Carbide and HSS

[Al T.]

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.

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

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

Is brazing the prefered way because of the lower temperatures required? Do the lower temperatures protect the hardness of the metal from being lost?

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 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.
