摘要
自主设计应用于双层气体保护非熔化极焊焊接工艺的焊枪枪头,实现D-GTAW焊接工艺。并与传统GTAW的电弧形态、电弧静特性以及焊缝熔池形貌进行比较。结果表明:D-GTAW焊接工艺能够改善传统GTAW的纯氩弧特性,提高热输入,增大焊道熔深。
The welding torch head for the welding process of D-GTAW was designed independently by comparing the arc shape, arc static characteristics and weld pool morphology of D-GTAW and traditional GTAW. The results show that D-GTAW welding process can improve the arc characteristics of pure argon used in traditional GTAW, and increased heat input and weld penetration.
