NOTE TO INSTRUCTOR: in Constructing Variations to the Questions in This

question 62

Multiple Choice

NOTE TO INSTRUCTOR: In constructing variations to the questions in this chapter, care should be taken in the selection of multiple choice responses. The responses used in the questions herein were carefully selected to avoid controversy. For instance in question 1 SMAW or FCAW were not used as responses because these processes are also widely used in plate girder manufacturing although the SAW process is the best selection for typifying this type of application. The text mentions only SAW for plate girder manufacturing and the other three choices offered in the quiz question 1 (RSW, RSEW, and TW) are clearly incorrect responses to this question. This caution is offered to avoid challenges by students who may be experienced welders and may question the correct answer to a multiple choice question if the responses are not carefully selected to avoid such controversy. The same caution is urged for other sample questions offered for this chapter.
-Which of the following types of welding is associated with inert gas shielding?
