EMAE 160 Welding Questions with Complete Solutions

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. T/F? Correct Answer-False. Welding failures always occur in the fusion zone of the weld joint, since this is the part of the joint that has been melted. T/F? Why? Correct Answer-FALSE. Failures also occur in the HAZ. Roughening of mating surfaces prior to gluing tends to: Correct Answer-Increase the strength of an adhesive joint Which arc...
