Carbide and HSS

I really don't know, I never studied the process. I only know they make door panels with honeycomb sandwiched together, and they put 'em in an oven and they come out brazed. Weight is a big factor in aircraft.

does this question pertain to bi-metal bandsaw blades? if so, it's an autogenous weld with pressure applied, then tempered. the little welders designed for this job are the only way to go.

I believe it's called "furnace brazing" . we do alot of it here, at my plant.

AL...........I GIVE UP NEVER TRIED, THEY GET IT TO ATTACH TO STEEL SAW BLADES BUT DON'T THINK I KNOW THE PROCESS LET'S CALL THE HOBART SCHOOL OF WELDING TECHNOLOGY. 1-888-462-2789 OR E-MAIL THEM AT WWW.HOBARTBROTHERS.COM HAVE THEM GET YOU TO THE APPLICATIONS LAB AND TALK TO KRIS, IVAN, BUTCH, DENNY, ANY OF THOSE FOLKS WILL KNOW THE PROCESS...........ROCK..........

You could, but I wouldn't trust it. Use silver braze.

Curiosity wants to know, can I weld carbide or high hardness steel with mig welder hh175?

I do not have a need to do this, I just wanted to know if it can be done with my equipment.
