Hey all,
So, I have a couple upcoming projects that will involve brazing some carbide to steel. I have a large stack of some older slightly worn carbide inserts (SPG, TPG mostly) that are somewhat used up and too large for my smaller South Bend 9. But, I do see a lot of utility in some of them for making a few brazed on bits, and some for scraper blades. Particularly some 6xx IC SPGs for scraping.
I am already getting a green wheel for my bench grinder, but wanted to learn more about what I'd need to braze them on.
Googling, and searching here turned up some good, but seemingly incomplete results.
So far I think it sounds like if I get silver braze in roughly 45-60% in either rod/roll form or maybe more ideally in foil form I'd be ok.
I was planning on using simple MAPP gas (though I may have access to borrow my shop mates Oxy/Act setup) along with some fire bricks for support/heat containment.
Would a welding (Airgas) store have some of what I am looking for?
Any other tips? Thoughts?
Thanks,
sbx
