True or false: Resistance welding processes make use of the heat generated by electrical resistance to achieve fusion of the parts to be joined; no pressure is used. Correct Answer-False True or false: Weld failures always occur in the fusion zone of the weld joint, since this is the part of the joint that has been melted. Correct Answer-False, occur in heat welding zones Which of the following arc welding processes uses a non-consumable electrode a. SMAW b. GMAW c. FCAW d. GTAW Correc...
