WELDING POSITIONS:
FEATURES
? Extremely low diffusible hydrogen weld deposit
? Low fumes and spatter
? Easy slag removal
? Able to bridge poor fit-up without burn-through
? Good impact toughness
? Virtually no slag coverage
? Smooth arc characteristic
BENEFITS
? Minimized risk of hydrogen-induced cracking
? No re-drying
? Excellent all position welding
? Resists cracking in severe applications
? Reduces clean-up time, minimizes risk of
inclusions
? Increases productivity, reduces part
rework/rejection
? Root welding with ceramic backing
? Automatic root welding with ceramic backing
