摘要
活性焊接是近十年发展起来的增大焊接熔深、改善焊缝成形和焊接质量、提高焊接生产效率的新技术。目前研究认为活性剂提高熔深的机理:一是活性剂可影响电弧特性,提高电弧的能量密度和作用于熔池的电弧力;二是活性剂影响了熔池的表面张力而提高了焊接熔深,或是两种原因兼而有之。在此利用活性焊剂在SUS304(厚度6 mm)的不锈钢板上进行各项试验,以得出该厚度不锈钢板的最佳工艺参数。
The welding with active agent has developed as a new joint technology in last decade because activate agent supplies a means of significantly improving weld penetration,performance and increasing the productivity of the welding process.Now the research on welding of aluminum and magnesium alloy with agent is ongoing.About the mechanism that activate agent can increase weld penetration,it was thought that arc visibly constricts in the presence of an activating agent,which improve arc energy density and arc force to pool,or that agent makes the pool to form a positive gradient and deeper weld penetration.Or both of them are playing role in increasing of weld penetration.The paper mainly is make use of the active flux in the SUS3046 mm thickness’ stainless steel to get the best craft parameters.
