What's wrong with my weld?

admin

Newbie welder here. Lincoln electric SP-175T5E setting so full heat and half speed. C25.035 wireWelding these bolts to a pipe.Is it too much wire? Not enough heat?I was able to just bang on the bolt and it cracked off.

Reply:All you did was lay wire on top. You never burned into the pipe. Crank the heat up , point wire in between bolt and pipe, burn into pipe and move to bolt.
Reply:What is that shinny stuff on the pipe. Cosmoline? If there is a rust inhibitor you may have to grind it off. Some of the greases used in products like Rectoseal breakout, are good to 1,800 degrees. So you would have to preheat that quite a bit before you could start welding on it.                        Sincerely,                            William McCormickIf I wasn't so.....crazy, I wouldn't try to act normal, and you would be afraid.
Reply:what william said.lightly grind that pipe down to shiney steel and crank up the heat.Miller 211Hypertherm PM 451961 Lincoln Idealarc 250HTP 221  True Wisdom only comes from Pain.
Reply:I agree it sucks :/ I will grind it down, use less wire and try prep the metal by heating it up. It was already on full heat so I can't do much there. How would I know if the welder isn't receiving enough power from the wall?

Reply:I might actually know something useful...  Start your bead an inch or so north or south of the bolt, get your puddle going, get some heat moving on your way into and around one side of the bolt.  Clean and repeat for other side.  Aledgedly, it's something I learned last weekend, seemed to work in practice.  Full disclosure though, I've had exactly one class thus far... SO Yeah, FWIW, YMMV, AFAIK, etc...ETA; AS for an answer to your question, zero penetration on the pipe is the problem, just no heat.
Reply:There is a thread here somewhere...About steel that is hard or impossible to weld toI only mention this because it looks like didnt penetrate the pipe at all Sent using Tapatalk Pro 2.0Miller 211Hypertherm PM 451961 Lincoln Idealarc 250HTP 221  True Wisdom only comes from Pain.
Reply:I like the bead ahead of time trick. I was thinking how the heck will I start a bead going around the bolt. It was just producing so much of a metal glob it was difficult to get going before having to stop. Thanks again guys.
Reply:It is producing the "glob" because you are feeding too much wire too fast.  Slow the wire down and let a puddle develop.  Hold out on the pipe a bit longer until a puddle shows and then "wash" it into the bolt as you work your way around.  If you are still having heat problems, pre-heat it with a torch.  Clean/shiny metal is your friend.Miller Dynasty 200DXMiller 252 Miller 250xMiller Syncrowave 250Miller AEAD200 LegendMiller 375 Xtreme plasmaLincoln WeldPak 100Victor O/A
Reply:Those welds look so cold I'm wondering if your getting 220v to the welder. Your not trying to run it on 110v are you? If not I would check your line feed and cord to makes sure both lines are feeding the welder. I had one of those and they are great little welders and you should be way short of wire speed at your settings, not over feeding.Yeah, I know, but it'll be ok!Lincoln Square wave 255Miller Vintage mig30a spoolgunThermal Dynamics Pacmaster 100xl plasmaSmith mc torchEllis 1600 band saw
Reply:how thick is the wall on the pipe? if it's a 220v welder there shouldn't be a reason for it not penetrating the pipe. when I'm welding different thicknesses of materials, I set the machine for the thicker of the two and focus the heat on that and then move to the thinner piece (referred to as "wash"ing above). There is no reason you shouldn't be able to travel at least half the circumference of the bolt in one pass. But in reality you should be able to do the full circumference if you get yourself in the right position and practice your pass before you actually weld it. Practice who you're going to change the angle of the gun, your body, etc. to maintain proper arc height and speed.There are no problems. There are only solutions. It's your duty to determine the right one.Hobart Handler 210Airco 225 Amp MSM Stinger
Reply:You should be able to easily start a bead on steel pipe. You should wiggle the torch though. Start with the torch perpendicular to the pipe aiming just at the pipe. Then turn the torch to the stud. Then back to the pipe then back to the stud. While slowly moving ahead.                       Sincerely,                            William McCormickIf I wasn't so.....crazy, I wouldn't try to act normal, and you would be afraid.
Reply:Also you may have too much heat, not enough wire, and the metal could be flame spraying or dripping onto the pipe. And it is getting picked up by the hot melted stud. I like a little crackle and pop, especially for something like that. You do not want the wire lifting up your torch. But you should here some electrical crackling. It does some cleaning of the surface.                       Sincerely,                            William McCormickIf I wasn't so.....crazy, I wouldn't try to act normal, and you would be afraid.
Reply:Try welding on something else about same settings thickness and see what it does.
Reply:I spent some time playing with various methods. I was successful with the "wash" method. I cleaned the metal a bit first and probably took about 1-2mm of pipe away to make it just a tad thinner. As for heat and wire speeds, I backed off a bit on the wire speed to about 3-3.5. Left the heat up on full. Either way I glanced inside the pipe and noticed that I was actually penetrating the metal. Thanks to all.Last edited by Shockwavecs; 05-04-2015 at 11:47 AM.Reason: edit
