it just got me fired up cause it sounded like you were sayin mig isn't good enough for you guys.
I have 3 years of woods ABUSE on the current buggy we beat on. and the only metal that broke was when we ripped the a-arm mounts out of the tube they were welded to. but the welds held, the tube is what gave.we re-welded and that was two years ago.
sorry in advance for the sound of frustration. I don't do the tack tack tack. skuWHEEZE that sombitch and let'er eat. you need heat, not too much, not too little either, you guys know the drill, so do I. it just got me fired up cause it sounded like you were sayin mig isn't good enough for you guys. I'm building an under 600 pound with liquids, mini. and using a 220 lincoln 175 pro mig. with a 75 / 25 gas mix. I have 3 years of woods ABUSE on the current buggy we beat on. and the only metal that broke was when we ripped the a-arm mounts out of the tube they were welded to. but the welds held, the tube is what gave.we re-welded and that was two years ago.all I'm ranting about here is, fabr is someone I respect from a builders perspective. despite what crap I'll hear for this, I think he know's what he's talking about and how to do this stuff and do it well. when he said he he would never final weld with mig anything that his ass rides in, I got a little chapped is all. cause thats all I do here at the house is mig. all I've ever done at the house. so now I question myself and if I need to get a tig for home and all that blah blah... dammit fabr, thanks
I mig most everything because thats the kind of welder I have. I used to have to tig where I worked and I would buy a tig if I found a good deal on one in a minute. Either is fine. Some feel that Tigging 4130 is a plus. Thus they do it. Thats all for preferance. There is a LOT more than I will get into on that after the weld here. But for joining the metal either can be good. Tigs tend to be pretty AND you get more control of the fill material in quanity and the type of fill material.But with proper methoeds and the right materails MIG is VERY strong. Some guys will get more mad at you talking about their welds than if they caught you with their girlfriend. But I will say the above parts in color need to be taken into account/thoughts. It IS COMPLETLEY possible that the arm mounts ripped the tube due to simple sheer strength issues. Steel can only take so much. BUT it is also very POSSIBLE that the welds HAZ area make the tube fail just outside the welds.I hear all the time guys who think they make stronger welds than the material as it often breaks just outside the weld. So the weld MUST be stronger!!But thats often cause the welding had somehow damaged the tube or other metal in a heat related way. Thus weakening it.You situation could have been either. Just be aware of that. Its not something to be ashamed of as much as learn from if it happens. So that you know to avoid it and not have welds that might fail and hurt you or someone.Its also why some prefer TIG as you do tend to have more heat control too. Done right.
