Abstract

The invention relates to the technical field of welding, and provides a pipeline argon arc spot welding process parameter quantitative control device. The device comprises a welding torch component and a clamping device. The welding torch component comprises a tungsten electrode clamping inner core, a tungsten electrode clamping jacket and a base. The tungsten electrode clamping inner core, the tungsten electrode clamping jacket and the base are both boss type open cylinder structure. The tungsten electrode clamping inner core, the tungsten electrode clamping jacket and the base are sleeved and connected sequentially from the inside to the outside. The clamping device is provided with a clamping part and a joint part. The pipe to be welded is fixed and positioned by the clamping part. Thebase is connected in the joint. The tungsten electrode clamps the extension line of the inner core axis through the butt joint of the pipe to be welded. The invention further provides a pipeline argonarc spot welding process parameter quantitative control system and method. The device, system and method solve the problems of the traditional manual welding method depending on the operator's experience in butt assembly and positioning, the height of the tungsten electrode and the arc angle in the welding process are artificially controlled, and the forming quality of the solder joint is affected.
