窄间隙TIG焊枪的研制

Research on Design of Narrow Gap TIG Welding Torch

针对我国工业中大厚壁结构件的焊接需求,设计窄间隙TIG焊枪,并用此焊枪进行工艺性试验,在焊接电流250A、焊接速度0.36m/min、送丝速度0.96m/min、气流量35L/min的规范参数下,成功进行窄间隙焊接,得到成型美观,无缺陷的焊缝。

To satisfy the needs of large-thick walled connectiong in Chinese industry, the narrow gap welding torch was designed, this narrow gap welding torch was used to carry out process experiment. While the welding-current is 250A, the welding-velocity is 0.36m/min, the feeding wire velocity is 0.96m/min and the rate of the protecting gas is 35L/min, the welding seams are perfect without defects.
