17-4 material has copper in it that is heat sensitive. the throat of the weld needs to be convexed to prevent cracking on thin material. Butter the ends of joint with filler metal of 17-4PH start on tack or use run off tabs.Tell your welder to make the senter of the weld look like its bulging...
No! 4043 is not a copatable filler metal for that base alloy. Your welders screwed up.Please don't try to butter over with 5356 now or you will have worse problems with mag silide weld fractures.The welds have to be cut out and replaced with 5356 or you are putting your company in a very bad...
First you should be using 100% argon gas. Voltage on base should be around 19 volts to start,tweek as needed.If you are using .035 dis. wire gun speed should be around 5. If you are using .045 dia. wire around 3. When porammertes are correct. You should be in a high spary transfer. Tweek example...
I think that we can join this material with regular mild steel mig wire. Example E70s-2 in G.M.A.W. process. I can't find any info to prove this. The company is now using 309 sst. filler that is causing many leaks in the tank of the product. The base materal is regular steel alun. diped. If we...
