A quick question for those who have welded on roll crushers. I have been welding on these rolls for about 6 years now, usually about once a year. I have tried various rod and the last time I did it, I was sold a McKay hard face rod, but I never did document the exact type. However, it worked really well.
This time around I ordered some more and told my supplier (Rebuilding and hard facing out of Spokane) that I wanted the same as last time. I recieved a Stoody hard face rod. While it seems to weld ok, I am getting lots of cracks along the weld bead. Tried changing to cooler temp and doing shorter beads and helped but didn't stop the problem. I just don't want to permanently damage them. Any suggestions from those who have done them for years?
