Welding castings

Just to add my twopenn'th, the principal of 'buttering' is to save expensive filler material on welding large cast sections where the remainder of the joint can be filled using a dissimilar or even a 6013 on a non-critical job. And as the faces would require machining for alignment, I'd spend the money on an adaptor plate. W/A

kinda, but IMHO also helps prevent HAZ cracking by producing a softer more ductile layer.....
