Portable All Position Tube TIG Welding Machine for Pipeline Construction

Product introduction

Closed all-position argon arc welding pipe automatic welding machine referred to as closed pipe welding machine.Closed pipe welding machine refers to the process of welding between pipe and pipe, pipe and elbow, pipe and flange, using the tube does not turn, tungsten needle inside the welding gun for 360 degree rotation welding form, the whole ring welding process is divided into 12 different sections, because the longer the welding time, the higher the workpiece temperature. A tube welder that can complete the entire welding process by setting the current in each section separately.

Closed pipe welding machine is mainly for stainless steel thin-wall pipe welding, using argon arc self-fusion welding, no wire filling, in welding, the inside of the round tube and the welding gun internal argon protection, less than 3mm pipe can be realized single-side welding, double-sided forming, and no matter inside or outside the tube weld forming good, no welding defects.

For semiconductor, food, medical, chemical and other industries, the quality requirements of the pipeline welding is very high. For such products that need to do strict inspection testing, the adoption of closed pipe welding machine can greatly save labor costs, improve work efficiency and product qualification rate.
