Hello all, got a problem with the overlap on an automated pipe to flange circular weld. Fixed torch, turntable setup. Weld is nice all the way round then for the last 10-15mm it decides to go skinny, more convex, and generally doesn't seem interested in the flange. These parts then get leak tested and a lot of them are leaking around the overlap. Easily reworked but this is high volume stuff so quite important to get rework down to a minimum.
Weldset - Fronius TransPuls Synergic 4000
Wire - CKY430M (W18LNb)
Pipe - Dia 54mm x t1.5mm, CKSUS409L
Flange - t8.0mm, SP220S
I now have this effect on several different machines welding the same type of flange with the same type of wire. When using a different wire (307) there is no problem. There are many other different components welded on these machines and others that do not show this problem. No matter what I try I can't seem to improve it.
Cheers,
Calso
