Utilizing Silicone-Bronze filler
Sometime soon I'll hopefully be starting my own manifold, I've done a few others but nothing terribly complicated. I'm planning on going with stainless for obvious durability reasons, as well as a fairly thick flange, and was wondering if I could use some Silicone-Bronze filler to help avoid distortion in the flange.
Also I was going to go for a more ram-horn or long tube manifold, as opposed to the mini-ram/log kind of deals I've done in the past. I'm going to have it bolted down as well but I was wondering if it would be worth the extra measure. The only thing that concerned me was that the strength of the actual bead is slightly reduced, which I could make up for with a bit more heat and less filler, but that kind of cancels the point of using it at all. I just wanted to hear what some experienced welders/ fabricators would say. |
Re: Utilizing Silicone-Bronze filler
i think it is like 80% strength but im not sure that is true at exhaust temps as well

Re: Utilizing Silicone-Bronze filler
I know its more flexible at heat than SS filler, whether thats good or bad is the question.

Re: Utilizing Silicone-Bronze filler
well when i tigged it, it seems like a was barely even on the peddle enough to even get the steel molten. it just kinda sucked in there and i smoothed it out with the arc. really weird to go from mild to try something like that.

I'm talking about using Silica-Bronze filler for Stainless. |
Re: Utilizing Silicone-Bronze filler
same thing

Re: Utilizing Silicone-Bronze filler
I've done it before, I didn't have to braze or preheat anything?
Care to elaborate? |
Re: Utilizing Silicone-Bronze filler
how are you doing this? torch, tig, heat gun set to nog?

Re: Utilizing Silicone-Bronze filler
I got a little Miller 200 tig, but my friend has a torch as well. I didn't think it needed preheating, just use the Bronze filler in place of the standard SS.
