Closed pipe automatic welding equipment

This machine is a special welding gun for all position automatic argon tungsten arc welding (without welding wire) designed for butt welding of various pipe fittings. Before welding, the sealing chamber shall be filled with shielding gas to ensure that the weld is well protected. Air cooling in gun body and fixture body. In addition, multiple clamps within the pipe diameter range are customized according to the customer's requirements. The clamp system can ensure the accurate positioning of the weldment without spot welding, so as to provide customers with efficient and high-quality special welding guns. It can precisely realize all position TIG pipe/tube welding, with high reproducibility of welding results and ideal welding effect. It is mainly used for pipe/tube welding in electronic, instrument, pharmaceutical, engineering installation, military and nuclear power industries.

Operating conditions

Ø Pipe diameter: MT80: φ 12.7- φ 76.2mm； (The minimum pipe diameter is no less than φ 12mm）

Ø Pipe thickness: ≤ 3mm; (Argon hydrogenation gas mixture is recommended for wall thickness above 2.5mm)

Ø Pipe material: stainless steel, carbon steel, titanium alloy, etc;

Ø Welding posture: all position welding;

Ø Welding form: butt joint, straight pipe to straight pipe, straight pipe to elbow, straight pipe to tee, etc;

Ø When welding carbon steel pipes, 5-8mm of the welded junction shall be polished to remove rust, exposing the original metal color;

Ø The pipe cut shall be flat, vertical and deburred, and there shall be no gap between the two pipes after they are aligned. The two pipes shall be spot welded together;

Clean the oil stain with acetone or alcohol;
