Nice looking welds, I've got a ways to go with my TIG'ing... Did you just use ER70S-2 filler?

Nice looking welds, I've got a ways to go with my TIG'ing... Did you just use ER70S-2 filler? I believe I used ER70S-6 but ER80-? might be better. I did try and heat the bar up before hand with some propane torches and a heat gun but the bar is relatively heavy so it was difficult to get much heat into it. I might have got the ends up to 150F or so before welding, which is still better than room temp. The stresses are going to be low at this end of the bar so my hunch is that if it didn't crack already it’s not going to crack in operation... we'll see. I've seen welded sway bars on race cars with welds connecting the arms to the long 'torsion spring' part of the bar,,,, and with that my hunch is that failure is immanent. Springs are very highly stressed and see many cycles which makes that a very bad place for a weld. The end link ends of the bar arms have very little stress in comparison. |
