What's wrong with my bike's welding?

admin

Hello I recently noticed this mark on my new bikes frame where the tip tube and headtube welding meets.Is my frame damaged? And since this is a bmx which I do tricks on, would this effect the frame when landing jumps etc?
Reply:Is it a custom made frame ? They ended the weld badly. They needed to add more filler weld.TO INVENT  YOU NEED A GOOD IMAGINATION  AND A  PILE OF JUNK'' - THOMAS EDISONMost Of The Time People Don't see The Quality of a Good Job Unitl they see a Bad Job !! -Scott Esplin
Reply:No it's not a custom. Is it bad?I emailed the company but they said its "only a weld overlap" and shouldn't effect anything. But I thought I'd ask here as well.

Reply:That's a weak spot, no doubt about it.Let them know that you have talked to welders, & they agree.I'd return it, that's going to break sooner or later.Probably when you least want it to.What type of frame?Buy American, or don't whine when you end up on the bread line.

Reply:I wouldn't worry too much. Not the most severely loaded part of the frame anyway, and I would hope there is a safety margin for minor defects.

Reply:Originally Posted by WeldingMachineIf your head tube pops off, it'll start right there.I'd return it personally, when a head tube rips off it is rarely pretty.

Reply:Do you guys really think that weld would fail before the pipe itself somewhere else on the bike?  Assuming this bike is something like 0.049 chromoly, wouldn't that weld, even with the small defect, have a higher PSI than the surrounding tube?  It seems to be a lot thicker than 0.049...edit:  well, I mean the weld would be lower PSI, but since it is more like 0.1, even if it were 40,000 psi and the 0.049 tube were 70,000 psi, the weld joint would be stronger than the rest of the tube...the defect is not on the edge of the weld.Last edited by IGBT; 02-13-2013 at 10:41 AM.

Reply:Originally Posted by shovelonCorrect!!!!!!Your frame is 4130. If it fails it will fail there first. Well at least if you have a catastrophic failure there and break your neck, you will have grounds for litigation. Believe me. Once the manufacturer hears of your concern, they will offer up a replacement. That crater is a disaster in the waiting. And good luck if you ever want to sell it, as a knowledgeable rider will not tolerate such defects.Where did you buy it?WeldingMachine, is that a Heckler?
Reply:WeldingMachine, is that a Heckler?
Reply:Originally Posted by BmxriderCan you explain to me how it would fail there first?I don't know anything about welding and I joined this forum to ask about my bikeI actually bought it from a bike shop interstate, since the all in my state didn't have it.But I linked this thread to the company and they are offering me a replacement
Reply:Originally Posted by shovelonThat crater is a stress riser right in the middle of the weld. Not to mention it in the termination of the entire joint. The first and last place that a weld usually fails is in the initiation or termination of a weld. Not only that, but on a bike you would want those initiations and terminations at the bottom or inside of the triangulation. When you hit berms or doing nose wheelies, or nose hops, you are pulling on that joint and flexing the crater to open up. Anyway, take the manufacturer's offer and replace it.

Reply:lol, those cranks are monster WeldingMachine.  i broke a tubular flight crank arm in the 80's, i have the hole scar where the crank entered my  leg.

Reply:Thanks Shovelon,The cranks are actually made by Shimano, part of the "saint DH" groupo.  Forged Alum, pretty light for as beefy as they are.  The best Shimano product ever IMHO!Can't wait for spring!Buy American, or don't whine when you end up on the bread line.

Reply:That bike looks Xpensive. Upside down forks;   WP no less?I would say Woi2ld is rite haha. You have a little ding staring you right between your eyes. The little ding is factory and on the hood, kinda like a cracked windshield on a brand new car. To visible of  start or finish weld.In my opionion, they should replace because of cosmetics in your face. No more questions asked, unless your a 200# + rider dropping 5 ft daily and put lots of pressure on your handlebars. Even then, those upside down WP forks would take alot of  blow , unless they leak from being worn. Doubt it.You could negotiate for a big  big rebate and then fill the ding with black caulking.  you could use the rebate for upgrades .I think they would owe you that much. The only problem is, the factory  is gona start to charge more to step up QC and all. REbate and upgrades would be: everyone wins.Bottom line, it doesnt look good on your hood from the factory: whoever welded it was IT. They gotta do something. Replace or Rebate.  Was it made in the USA, AUSTRIA , CHINA, MEXICO or somewhere??Last edited by Insaneride; 02-13-2013 at 09:36 PM.Reason: Then you could try to destroy IT
Reply:It'll be fine... My kink whip has a similar weld where the bottom bracket meets with the chain stay. I've been riding that frame for about 2 years and a half now and i haven't had a problem with it. Although like most of these guys said any frame can break just cause the frame is 4130 chromoly doesn't mean it won't break. Are you new to riding? I saw your post on vital i don't post on that site no more since everyone acts like smartasses so i tend to stay away from it i just lurk every now and then. Back to my point your frame will be fine, like i said before my frame has something similar to yours in fact i think it's a bit bigger and i've ridden it for 2 years i've also done decent drops on it. I've gone through a bottom bracket and i just broke my pedals a week ago the frame is still running fine. It's just wear and tear don't stress over it i know that feeling when my bike was new i would come home and clean it every day whenever i fell or bailed out the first thing i'd check would be my bike. Ultimately don't worry about it you'll be fine =)
Reply:Personally I wouldn't be in complete fear of that particular defect in itself. There are many factors that will contribute to the lifespan of that weldment. From a pure fatigue standoint, the toes of the weld are going to be the suspect areas for cracks to start, much more so than the middle of the fillet. Just doing a tiny tack weld to fill the void would probably end up doing more damage than good. If I had money to bet, it would be that that frame will eventually fail, but not from that defect.
Reply:I'd agree with that, if it was aluminum and on a motorbike subjected to constant vibrations I'd worry but on that chromoly bmx frame I wouldn't even give it a second thought as far as a safety factormiller 330a bp TIGmiller dynasty 200DX TIGmillermatic 185 MIGthermal dynamics cutmaster 101 plasma cuttersnap-on YA5550 plasma cutterhypertherm powermax 30 plasma cutterbaileigh CS225 cold sawetc....
Reply:Too much worrying going on in this thread.  The frame is fine.  The headtube is not going to break off where that "crater" is.  People are forgetting that the heavier bottom tube connects there as well, which would have to provide zero resistance for that to break off at the top.That frame is good for quite a few hard crashes.  The frame will hold up until OP decides it's time to quit BMX'ing or upgrades. lolBack in the early 2000's I rode a Federal bike with my own fair share of burly parts.  Broke quite a few things, but never a frame.
