焊条电弧焊单面焊双面成形技术的操作要领与技术(国外英文资料) The operation essentials and technology of single side welding double sided forming technology of welding rod arc welding. Operation essentials and technology of single side welding double sided forming technology of arc welding Chu Mei Hua Jiangsu Hongxing Pressure Vessel Manufacturing Co., Ltd. Abstract: the main points and skills of double sided welding technology of arc welding are introduced. Namely: five essentials and Six Skills, which is based on absorbing the experience of welder training across the country, after years of exploration and practice summed up a set of suitable for boiler and pressure vessel welding evidence of the welder training teaching method. After many welders training proved that it can achieve twice the result with half the effort. Key words: single-sided welding, double sided forming, essentials, techniques, welder training. 1, preface One side welding technology is SMAW difficult a technique, but it is also a kind of skill test, technical competition, especially the basic skills of boiler and pressure vessel welder must master. As soon as possible to master the operation tips and techniques of forming technology of one side welding, is not only a skill test, about technology contest and boiler and pressure vessel welder forensics problem, but also the main content of welder training school coach must explain and demonstrate the. In this paper, the following five methods (see, hear, accurate, short, control) and six kinds of skills (solid, transport, start point, end arc, joint, closing), if master the five essentials and six basic skills method, the welding quality will be qualified for the inside and outside the weld a. Taking arc welding as an example, the specific application of five essentials and Six Skills in the arc welding, single side welding, double face forming and backing welding are introduced respectively. 2, five essentials 2.1 see In the welding process, in addition to carefully observe
