Reply:Morgan,Not trying to be a smartazz, but you could use a LOT more practice before you take on a bumper project where the bumper may actually bump something.What I'm seeing on the box you fabricated, are not welds.  What it looks more like to me, are what are commonly referred to as "bird droppings".A lot more practice on scrap in the flat position is recommended before you take on this project.  Not saying a bumper is a life or death situation, but if it falls off, rolls under the vehicle, it could make for a bad day.You don't just go to a box store, buy a squirt welder, and become a welder overnite.  Takes time and practice.EDIT:  Went back and looked at previous postings.  To be honest, you don't have the experience to even be trying to weld 3/8" material with a 125A machine.  Accident looking for a place to happen.Last edited by SundownIII; 03-28-2008 at 01:29 PM.Reason: additionSyncro 250 DX Dynasty 200 DXMM 251 w/30A SG XMT 304 w/714 Feeder & Optima PulserHH187Dialarc 250 AC/DCHypertherm PM 1250Smith, Harris, Victor O/ASmith and Thermco Gas MixersAccess to a full fab shop with CNC Plasma, Water Jet, etc.
Reply:taking on something? i sorry but bad day waitn to happen? if it falls down i am learning and having lots of fun i am not new to cars or anything like that. I know it will turn out great when i put my mind to something it usaly works. I wish somone like you would not just hate on what i am doing even if i need more practice why not try to be helpful or why even comment, those welds were on a consistant weld that i ground down flat rewelded reground and rewelded again i am sure they are not pretty but it can withhold me jumping on it and i weight 230 lbs , already i am able to form a bead most of the time like 70% with low slag on fluxcore, i am sorry my welding has upset you in anyway..... when i am just trying to have fun. alot of people cant even make what i have made with experience , you tell me later if it looks like ****,Last edited by morgan320i; 03-28-2008 at 06:53 PM.
Reply:day 2 of build i still have 2 more suports and a skid plate to add then light brackets on top
Reply:p.s i joined this forum for fun so i can learn alot and meet people who can teach me things about welding cause i crave more i have been here 3 days and you .... make me not wanna  even read here whatever lol
Reply:dude just practice practice practice practice practice practice practice .I have been trying to learn how to Oxy-Acetylene weld for a little over a week now and my welds suck 10 kinds of crap. I thought I did alright untill I started using RG45 filler.No filler:and now the mess that is my weld with filler:keep at it and have fun. but now im off to practice practice practice......
Reply:Sorry Morgan,I'm sure, with your skill and attitude, you'll be fully qualified to build an aircraft carrier and weld up the nuclear reactor piping within the next couple weeks.I thought I gave some pretty good advice.  Practice on scrap that doesn't matter before welding on something that goes on the road and could hurt someone.Syncro 250 DX Dynasty 200 DXMM 251 w/30A SG XMT 304 w/714 Feeder & Optima PulserHH187Dialarc 250 AC/DCHypertherm PM 1250Smith, Harris, Victor O/ASmith and Thermco Gas MixersAccess to a full fab shop with CNC Plasma, Water Jet, etc.
Reply:haha i hear ya morgan... you are doing a really good job for only welding for 3 days i think! my personal preference is to use gas w/ mig.keep it up!Certified Welding Inspector at your service...Level II Nuclear Welding InspectorLevel II Nuclear Electrical InspectorLevel II Nuclear Civil InspectorLevel II Ultrasonic Thickness Testing TechnicianCertified Smartass,and Wise Acre

Reply:We call that coon sh$t on a log down here Sundown. Morgan, if you don't want to hear what the pros have to say, don't ask. I don't care how many times you have taken a grinder to it that does not appear to be a sound weld. In fact it looks awfully cold. It doesn't matter if you have 30 passes in there, if none of them are done correctly then it isn't a sound weld. Keep in mind that if this thing falls off going down the highway you are the one with the least worries about getting hurt. Now the ones behind you are a different story, and you can be held civilly and criminally liable. Ask any pro here and they will all tell you that the safety of others is your primary concern with anything you build.Practice your a$$ off on something that can't possibly hurt someone and one day you will get to where there is no concern. It's not hatin' on you. It's just pros telling the truth. You are asking guys who don't practice for welding tests, yet will take them on any given day with no worries (that's what makes them pros) to give an opinion on your work. If you can't handle that opinion don't ask for it. Go to the hobby boards for pats on the back.BTW Sundown, the synchro 250 is a dead duck, lol. Switched it to dc and turned the power on, heard a loud brrrt, saw a blue flash and now it's dead, lol.The difference between art and craft is the quality of the workmanship. I am an artist.
Reply:i dont want a pat on the back just there is a dif between crit/ and just being mean i cant build anything but when it comes to cars i can
Reply:Your fitment looks good, the layout is nice. You would benefit enormously by seeking the advice and help of someone near you with welding experience. Throw some good hot mig or tig welds on that assembly and they would be ALL THAT!City of L.A.

Reply:Morgan,This can be a tough crowd. It is also free access to some of the best and brightest welding minds out there. Personally, I'd rather have someone call B.S. on me, without sugar coating, if I was doing something with possible safety problems.Fatigue failures do happen unexpectedly. I think you need more heat. You should be able to see the puddle "wet out" on the edges. If you were set up right in the first place you would not have to grind and re-weld. Hang in there and good luck.
Reply:I concur; the truth may hurt but egos kill. Grind back a reweld would be my advice, fitup seems good enough to be worth it.Airco 300 squarewaveMig welding center...Powcon sm300/LN 25Powcon sm200/PD lHypertherm PM 1100Miller AEAD 200LE W/LN25 FCand now another sm200 pd l combo.
Reply:Maybe grind flat first sure, but the key in this instance is going to be gouge it out (grove it out) and reweld. That's from the outside on that corner. Get more down in and not so much top. Use a small cheapo propane torch to heat that puppy up good first, you'll be surprised.

Reply:Morgan, take the advice or leave it.....but they are right. The welds are not up to snuff by a good margin. Gasless flux core is not a great idea either. It is notorious for cracking under stress. You fit up skills are sufficient for now, but the welding skill needs more work, plain and simple. The replies were not even close to as rough as it will get if your bumper causes an accident or loss of life. Then it will cost you dearly and be exponentially rougher. Liability on vehicle modifications is a big deal. You will be asking for it believing otherwise. If someone kills one of my family members from garbage welds, I will own their azz legally and take them to the cleaners. Prison time would not be an option..it would be mandatory. But then what do I know..you have been doing it three days...I've been doing it well over 20 years.
Reply:I dunno maybe you could have a fab shop bend plate 90* for the frame mounts instead of welding two plates together?I like your design simple and clean
Reply:not all of the presure is on those plates it is bolted to the side so even if they were to sheer off i dunno how there would be the sides holding it pluse the other 2 mounts that will be at the bottom .only thing i can think of that would make it break is if i hit something even then i most i see happening is the bracking snapping in 2 but not falling off

Reply:can this thread end lol you think i am not listening but i am to what people have to say when its positive criticism  i was just adding my feedback and what i thought about it
Reply:Your welds are awesome! you the man!I like to party!Morgan, we got all kinds here....true hot-rods,self proclaimed hot rods,and wanna be's..there is a vault of knowlege here (go with the seniority not the degrees). Instead of slamming your work (your fab looks good, welds need some help) try this.....weld together a couple plates just as you did for your brackets and the infamous grogan welds and put one in a vise and smack the other plate from the back side. That's what everybody's trying to say. You may need a little more time, but, you also need a machine with more punch. Again, fab looks fine, you need more fire....KennyYeah, yeah, I know you are a weldor too. But, are you a good one?

Reply:Here is an example: 20 foot extension ladder falls out of the back of a pickup going down the interstate. It was tied down with a rubber bungie strap that broke. The guy in the car behind the pickup died. The guy in the pickup, a fireman btw, went to jail. He managed to get aquitted, but he lost everything to the lawyers. The civil suit is ongoing. At 65 mph even a small piece of steel can be deadly.The difference between art and craft is the quality of the workmanship. I am an artist.
Reply:im going to disagree with just about everyone on this topic.  I say do whatever you want, if you want to build a bumper, go for it.  Besides, how can a steel bumper be ANY WORSE than the piece of crap fiberglass "bumpers" they put on cars nowadays.I do agree with the fact that you do need more welding practice, but the tubework looks pretty good to me.

Reply:Drivethruboy,That's just about the stupidist argument I've heard this week.You must be one of those "box store" wannabe welders who just bought a 125A squirtgun welder and thinks he's ready to start building trailers and making frame repairs on his vehicle.Had the OP been talking about building a mig cart or yard ornaments, I would not have even commented.  He's talking about making STRUCTURAL modifications to a vehicle intended for highway use.  For your info, that flimsy fiberglas skin is backed up by a heavy, energy absorbing steel member, which was designed to minimize injury to the vehicle occupants.The welds I saw have no business on the highway.  The OP does not have the experience to be taking on this project, and even if he did, the machine he's using is not up to the task.  For 3/8" material he needs to be using at least a 200A 220V machine, or it needs to be stick welded.  End of discussion.Your comments are exactly what I've come to expect from today's newbe welders who don't have a clue about what they're talking about.  That's the problem with some of these cheap, "consumer" welders and the people who buy them.  The weld may look satisfactory on the surface and have absolutely no penetration (insufficient heat).  I'd appreciate it if you kept your comments to something which you do have experience with (not much).Even the design of the bumper system, to me, is questionable.  In VA I don't think that design would even pass state inspection.  The contact point for the bumper is too high.  In the event of a rear end crash, that design would cause the truck to ride up and over/into the passenger compartment of the front vehicle.  That bumper would not even make contact with 90% of the rear bumpers on today's passenger cars.Bad design combined with poor execution is a prescription for disaster.BTW:  I do have over 50 years of welding experience so I'm not "talking thru my hat".Syncro 250 DX Dynasty 200 DXMM 251 w/30A SG XMT 304 w/714 Feeder & Optima PulserHH187Dialarc 250 AC/DCHypertherm PM 1250Smith, Harris, Victor O/ASmith and Thermco Gas MixersAccess to a full fab shop with CNC Plasma, Water Jet, etc.
Reply:Sundown, I think you said it pretty well. If the kid had any experience he would know his machine is not up to what he is trying to do with it. Bet he will be surprised when it falls off and he runs over it. Wonder what it will tear off the truck when this happens.
Reply:[QUOTE=SundownIII;176885] p.s duh it wouldnt hit somones rear bumper if it was doneits like 1 foot over any bumper ........... there are more supports going down to the bottom sub frame i am not that retarded check out any bumper for a dakota that is fabbed its using the same points and directions. i bought a 110 for versatility. i am not making hard core ****. if i did it every day or big things id buy a 6k+ welder on the spot not worth it to me if im going to be welding only a few times a year. and p.s il probably get the big plates re welded but as far as the tubing i think i will do it myself i am getting a constant bead and good heat marks around the tubing i am sure its not amazing but its not going anywhere. you guys need to get over yourself and this topic wasn't meant to be a fight i was showing something i am working on.......................Last edited by morgan320i; 04-01-2008 at 04:33 PM.
Reply:Morgan,The general context of my postings was not intended to beat you up for your effort.  On one hand, I can appreciate the fact that you bought a welder and are learning to use it.  I can also see that you put a lot of effort and thought into bending the pipe, cutting the brackets, etc.My background for many years was in military special ops.  Mistakes or failure to follow established procedures got people killed.  Never been one to "soft shoe" around an important issue.Welding can be a great experience and can allow a trained person to create things which are not commonly available or would cost an arm and a leg.  As with most skills, though, it is not learned overnight.  Part of that experience is also knowing the limitations of the material and equipment you're dealing with.Twenty years ago, we didn't have cheap wirefeed welders available to the public.  What was available were the inexpensive AC buzzboxes which many learned to weld with.  They were less forgiving than the wire feeders so people had to learn to "read the puddle".  The wire feeders on the other hand can often lay down what appears to be a good bead, but when tested (say with a 2lb  hammer) the weld fails because there was no penetration into the base medal.Unless we in the industry (read oldtimers) start to police what's happening, it won't be long before a Certification Card will be required to buy a welder, buy a bottle of gas, or buy a roll of flux core wire.  Scuba divers already encounter this, and I can assure you that welding has much more potential for danger to others (other than the one using the equipment) than Scuba does.Keep working at it and a few years down the road, you'll look back and better understand where we're coming fromSyncro 250 DX Dynasty 200 DXMM 251 w/30A SG XMT 304 w/714 Feeder & Optima PulserHH187Dialarc 250 AC/DCHypertherm PM 1250Smith, Harris, Victor O/ASmith and Thermco Gas MixersAccess to a full fab shop with CNC Plasma, Water Jet, etc.

Reply:Morgan, it seems to me you are the one bringing the attitude. No one blew sunshine up your butt and you didn't like it. You did not take the advise or criticism well at all. Some of us have been doing this forever and have seen the rise and fall of new guys like yourself...so excuse the crap outta us if we try to prevent you from making a big mistake. You tell us to get over ourselves....now that is arrogant. Try to get a job welding with an attitude like that and you'll see what the real world of welding is like. You either perform at 100% or you go home if you can. With some of the stuff I used to do...peform badly and you die. This bumper doesn't need a 6k+ welder. It simply needs one that will handle what you are welding at the moment. That comment shows the lack of experience you actually have. It has nothing to do with the price of the machine, it has everything to do with its capabilities. No one has any business trying to weld 3/8 with a 120v machine on a critical item...and yes, a bumper is considered a critical item.So, since you aren't listening anyway...do whatever you want.
Reply:lmfao? am i saying anything bad about anyone here.. where is my attitude lol
Reply:Your attitude is you know more than we do. Lots of us have a list of certs as long as our arms that say we know more....and better yet....can prove it. No one called you any names, no one was rough on you at all and everyone tried to help you. But that was not what you wanted obviously.
Reply:now onto your attacks of my opinion:He's talking about making STRUCTURAL modifications to a vehicle intended for highway use. For your info, that flimsy fiberglas skin is backed up by a heavy, energy absorbing steel member, which was designed to minimize injury to the vehicle occupants.-take a look at the FACTORY welds on your car, his welds are not much behindThe welds I saw have no business on the highway. The OP does not have the experience to be taking on this project, and even if he did, the machine he's using is not up to the task. For 3/8" material he needs to be using at least a 200A 220V machine, or it needs to be stick welded. End of discussion.-sorry, but not end of discussion, preheat and beveling goes along way, mr professional.Your comments are exactly what I've come to expect from today's newbe welders who don't have a clue about what they're talking about. That's the problem with some of these cheap, "consumer" welders and the people who buy them. The weld may look satisfactory on the surface and have absolutely no penetration (insufficient heat). I'd appreciate it if you kept your comments to something which you do have experience with (not much).-im hardly a newbie, in fact im a structural steel welder-pipe and plate-7018 6010 and innershield 232.  Oh, i also TIG, MIG, and held a job in structural steel for over a year based simply on the fact that i can burn better than most of you "highly qualified" old timer idiots.  I also have a degree in welding, and actually understand metallurgy, heat input, heat treatment, design and fabrication, machining, layout etc...  I dont just stick two peices of metal together and pray they stick.Even the design of the bumper system, to me, is questionable. In VA I don't think that design would even pass state inspection. The contact point for the bumper is too high. In the event of a rear end crash, that design would cause the truck to ride up and over/into the passenger compartment of the front vehicle. That bumper would not even make contact with 90% of the rear bumpers on today's passenger cars.-i guess my 99 dodge diesel with an after market STEEL bumper, that is not designed to buckle in an accident is not okay either because my truck is on a 6" lift and would mangle some foreign made sedanAnd yes i do have a squirt gun welder in my garage, two of them in fact.  Except they are millermatic 250's, maybe you can come over and show me how to use them one day...50 years of experience, yea, ive seen what so called experts can do, most of them are not very impressive.Next time you feel like spouting off from your poop shoot, point in another directiondont pretend to know me, what i do, or what i own, or what my capabilities aresundown-i think not, you can take your ignorant comments and shove them where the SUNDONTSHINEthanks-
