No milk welds on what I did today. Oh god Ill tell ya,I assed this guys kettle up today. I dont think it is salvageable. It was my fault. I didnt have anything to do a test weld so I went right into it. I made a couple of mistakes but the real reason I think is that the kettle is so thin. It is one of those really cheap ones I think.
Its melting away before I have even made a mark on the fitting. Im using a gas lens, and I am getting the tungsten tip right in there close trying to keep all of the heat on the fitting. But it is tough.
Finally had to move up from thin filler rod to 3/32 just to get some metal in there before the kettle wall fell away. I dont know, maybe I am doing something wrong.
I hate to pass the buck but I think the kettle needs to be thicker.
What I did wrong though was fill the entire kettle with back purge gas instead of a direct back flow on the weld.
With the wall getting so hot and the fitting drinking up all the heat there is not enough shielding the back is crystallized in at least two spots.
I never have any trouble with keggles but those cheap pots are a b****, unless there is a trick.
Now I am putting off calling the guy to tell him.
Thankfully it is a cheapo.
