Analysis on welding processing properties of plasma-TIG coupling arc hybrid welding

  • 摘要: 针对低碳钢材料焊接效率低的问题,提出了等离子-TIG耦合电弧焊接方法,通过设计集约化枪体结构促使等离子和TIG电弧在电磁力作用下实现稳定耦合,优化复合焊接热源特征,并研究了电弧形态、焊缝成形和力学性能.结果表明,等离子-TIG耦合电弧具有优异的深熔焊接特性,相对于等离子和TIG焊接方法具有更加合理的深宽比,且对熔滴、熔池有震荡搅拌效果,促使晶粒细化,并降低熔合区联生结晶倾向.使用5 mm厚Q235B钢板进行对接试验,实现了稳定的单面焊接双面成形,焊缝美观无缺陷且抗拉强度优于母材.
    Abstract: The plasma -TIG coupling arc hybrid welding process was proposed to improve the welding efficiency of mild steel. The stable coupling arc of plasma and TIG is realized under the action of electromagnetic force by designing the intensive torch, and the welding heat source characteristics of the coupling arc have been optimized. The arc shape, weld formation and, mechanical properties are analyzed. The results showed the coupling arc still have good deep penetration welding characteristics. Compared with plasma and TIG welding method, the coupled arc has more reasonable depth-width radio, and has the effect of shock stirring on droplet and welding pool, which promotes grain refinement and reduces the tendency of joint crystallization in fusion zone. One-side welding both sides formation could be achieved by use of the butt welding test with 5 mm thick Q235B steel plates, the weld was smooth without defects and the tensile strength was better than the base metal.
