Hi All, i got dragged into our shop today at work as they were having issues with a automated welder. It's used to weld branches or outlets on pipe work. It's quite an old set up but all seems to be functioning well apart from the weld profile on the finished article. At the top of the weld, lets call it 12 0'clock the profile is fine, but at 3 & 9 o'clock its not. Best way I can describe it is its "muffin top" Ive havent been professionally welding for about 20 yrs but then again this machine must be as old if not older, I just can work out what I want to do to improve the profile. If I was manually welding I would change the angle of the torch at these points but that's not an option with the setup we have. What I can do is; Change the pass speed Change the weave amount Change the amperage Change the distance the torch is from the work piece Change the wire speed Where should I start? I tried a few of the above today but it didn't improve matters. I cut open one of the welds and although I would have preferred some more penetration the throat thickness was fine, It will be holding 15 bar of water and I would say it was what I used to refer to as a class II weld, not penetrated but no porosity and throat thickness as wide as the pipe wall thickness. Is this as good as it gets with this set up Am I expecting to much from an robotic weld?
