Downloaded from https://www.everyspec.com MIL-STD-336 FOREWORD This document contains information on a welding process where fusion is w achieved over the entire abutting surfaces of two plates, bars or tubes without utilization of filler metal in one welding operation. This fusion is achieved by the heat generated by the resistance to the flow of electric current between the faying surfaces followed by the application of pressure when the required heating is completed. iii ---
