Reply:I don't know the specific alloys in question, but MANY hardfacing/hard-surfacing fillers will "check crack" or "cross check". No matter what.If the filler you are using is subject to check cracking, there is pretty much nothing you can do about that (except use a different alloy not subject to cross checking). But cross checking is not a fault, it is just cosmetic (although it can look pretty severe!). The best laid schemes ... Gang oft agley ...
