Horizontal Pipe Inner Wall Straight Seam TIG Equipment

Horizontal Pipe Inner Wall Straight Seam TIG Equipment

This model is specially designed to cope with the application of MIG remelting or wire filling and cover welding of the root for the straight seam of the inner wall of the welded pipe required by the latest straight seam welded pipe standard. This model is compact, space saving and powerful. GTAW process is adopted to be suitable for automatic reflow welding or wire filling and cover welding of carbon steel wire, stainless steel wire, nickel base alloy wire and other wires.

Overview
Recommended Products

Straight seam welding system adopts the mode of horizontal movement of the workpiece for welding, and the welding gun system is fixed on the base of the tail.

Ø The welding torch head is installed on the high rigid round tube, and the linear motion of the linear module driven by the stepper motor and the special mechanism are converted into the up and down movement of the welding torch, so as to realize the contact of the welding torch to the workpiece and AVC tracking.

Ø The welding torch has automatic arc voltage tracking function, when the welding torch and surfacing surface deviation, it can adjust automatically in time.

Ø The welding gun including the whole head is cooled by temperature-controlled forced circulating water, which can realize long-term continuous welding.

It is powered by EWM Germany TETRIX 452 DC pulse arc welding power supply and the TETRIX 200 Hot Wire thermal wire power supply.
