中文摘要: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0.96 m/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。
英文摘要:Design the narrow gap welding torch to satisfy the needs of large-thick walled connectiong in Chinese industry, and use this narrow gap welding torch to have 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 seams are perfect without defects.
