【摘要】：文中系统开展了Q235薄钢板单丝MAG,双丝MAG以及TIG-MAG复合等电弧搭接焊工艺研究,对上述焊接方法的焊接接头成形、微观组织、拉伸性能以及焊接熔化效率进行了对比分析。研究结果表明,在本试验条件下,单丝MAG焊接速度可达到0.9 m/min,焊接飞溅较少;双丝MAG焊速度可达到1.8 m/min,焊接飞溅多于单丝MAG焊;TIG-MAG复合焊接速度可提高到2.4 m/min,焊接飞溅最少。通过计算表明,与单丝MAG焊和双丝MAG焊相比,TIG-MAG复合搭接焊方法具有显著的低焊接热输入和高熔化效率特征。
[Abstract]:In this paper, the arc lap welding process of Q235 thin steel plate monofilament MAG, double wire MAG and TIG-MAG composite is studied systematically, and the welding joint forming, microstructure, tensile properties and welding melting efficiency of the above welding methods are compared and analyzed. The results show that under the experimental conditions, the welding speed of single wire MAG can reach 0.9m 鈮，
