Welding Equipment and Techniques
The technician may be called upon to repair important aircraft parts by welding. If the technician does not understand the process of welding or is careless, the weld may fail. It is, therefore, essential to be well acquainted with the approved welded repairs, techniques for welding, and the operation of welding equipment. The technician who is not sufficiently skilled to perform an airworthy welded repair should call upon a qualified welder to do the work. In any event, the technician must be able to inspect and evaluate the quality of any welded structure or welded repair.
