1. AWS groups welding processes based primarily on ?: Mode of energy trans- fer, and the influence of capillary action in the effecting distribution of filler metals in the joint 2. AWS defines welding as?: A joining process producing coalescence of materials by heating them the the welding temperature with, or without the application of pressure or by the application of pressure alone, and without or without the use of filler metal. 3. AWS welding processes are grouped into which major follow...
