摘　　要：轮式洗砂机斗轮圆板多采用分瓣下料、拼焊成型的制造工艺。传统焊接方法施焊需要预先开坡口,焊接效率低、变形大,对斗轮圆板的整体成型造成了一定困扰。利用活性TIG焊、不开坡口的方式对8 mm厚低碳钢试件进行双面焊接试验。活性TIG焊工艺参数对焊缝成型的影响与普通TIG有所不同。在适当的焊接工艺参数条件下,活性TIG焊双面拼焊成型效果良好,在不开坡口、无预留装配间隙、无焊材填充的条件下实现了双面对接,无需进行背面清根、焊接变形校正等工序,大幅提高了焊接效率。The circular plate of the bucket wheel of the wheel sand washing machine is often manufactured using the manufacturing process of segmented cutting and welding.Traditional welding methods require pre groove preparation,resulting in low welding efficiency and significant welding deformation,which poses certain challenges to the overall formation of the bucket wheel circular plate.Using active TIG welding,double-sided welding tests were conducted on 8 mm thick low carbon steel specimens without opening grooves.The influence of active TIG welding process parameters on weld formation is different from that of ordinary TIG.Under appropriate welding process parameters,the double-sided splicing effect of active TIG welding is good.It achieves double-sided docking without opening grooves,reserving assembly gaps,or filling welding materials,without the need for back cleaning,welding deformation correction,and other processes,greatly increasing welding efficiency.
