[TheForge] Silicon bronze

[Dave Mudge]

I have a client that makes large gears. He is making a brass  (or similar
alloy ) gear that is roughly 6" wide and 36" diameter. Somehow they cut a
gouge in the top of one tooth. Maybe 1/2" wide and 1/2" deep and a couple
inches long. Asked me if I could silver solder the gouge. I said that one
really can't "build up" silver solder but I happen to have a large spool of
Silicon bronze mig wire. I am sure that I can fill the gouge with that. Any
ideas on machine settings (Millermatic 251)
or preheat or process? Anything will be helpful. thanks, dave
