1 前言为了适应工业发展焊接量增加的需要和焊工减少、老龄化的现状,急需提高焊接效率和质量,为此日本对MAG焊作了很多研究和改进。现将日本MAG焊最近的发展概况作一介绍。 2 MAG焊最近的发展概况 2.1 CO_2焊、MAG焊的发展概况 CO_2焊、MAG焊用于高速焊接时,易产生大颗粒的飞溅,清除飞溅需要大量辅助工时,阻碍了该工艺的使用和发展。为此日本分析了飞溅产生的原因,有针对性的采用控制、降低飞溅产生时的电流,减少飞溅,同
1 Preface In order to meet the needs of the industrial development of welding volume increase and the reduction of welders, the status quo of aging, the urgent need to improve the welding efficiency and quality, for which Japan made a lot of MAG welding research and improvement. MAG welding is Japan’s latest development overview for an introduction. 2 Recent Development of MAG Welding 2.1 Development of CO 2 Welding and MAG Welding CO 2 welding and MAG welding are easy to produce large particles when they are used for high speed welding. Large numbers of auxiliary man-hours are required to clear the spatter, hindering the use and development of the process. To this end Japan analyzed the causes of spatter, the use of targeted control to reduce the current generated when the spatter to reduce spatter, with
