Got the brass down pat guys Whoo Hoo. I will post some pics later but What I did was switch over to A/C with full Penetration. I managed to get the top edges of the metal melt into the weld and just poured in the brass filler rod into the gap. I was so stoked to have it happen. The base metal was 12 gauge solid brass and the filler was 16 gauge sheet cut to 1/8th"

I started at 90 amps and had very little penetration with it. Except at the very end of the weld. I turned up by 10 amps with each test weld I did. I noticed that the penetration of each weld was getting longer till it was half way down the weld with the second last test. So I started preheating the metal and then welding it. I got to 6 preheat passes and that is when the entire weld had decent penetration. Success.

On the final test I had decent penetration but nothing fantastic. I could see minor bubbling of the base metal on the back. Showed my boss and he was in awe lol.

These pieces do not have to have perfect penetrations at all. They only need to be decent welds on the top of the brass. We grind the corners down and shape them with a barrel sander to round them off. After that we use a stroke sander to put a sanded finish on the metal.

So I ground it down and it looked perfect. Everyone was ecstatic that I was able to pull this off. I wound up at 115 amps with the final weld and I was so happy. That is what I love about Welding. Being able to master something you know damn well you can do and nailing the hell out of it despite second guessing yourself.

Hey there,

Great to hear that you're kickin' goals. Thats real grass roots stuff, Having a problem and having to work it out by yourself. Really good job. Now to ask the boss for a pay rise. (Not LOL)

Well I am there through a temp agency but they said that once the contract is due they are going to negotiate a higher pay for me. She told me no way that they should be paying for a welder at the rate I am getting now. I am expecting a 10 to 15% boost next month. Yay
