Abstract

The utility model relates to the technical field of all-position pipe welding machines, in particular to a sealed all-position pipe welding machine which comprises a base, and supporting pads are installed at the four corners of the bottom of the base. The two gears rotate to drive the two bidirectional threaded rods to rotate correspondingly, and the bidirectional threaded rods rotate to drive the two movable plates to move relatively outside the bidirectional threaded rods, so that the two arc-shaped limiting plates are driven to move relatively to clamp the metal pipes, and limiting welding of the metal pipes of different sizes is facilitated; and by arranging a protection pad, damage to the exterior of the metal pipe is avoided, and therefore the problem that when a traditional sealed type all-position pipe welding machine conducts limiting welding on pipelines of the same size in the welding process, the pipelines need to be limited manually, and consequently the welding efficiency is low is effectively solved.

Description

Technical Field

[0001] The utility model relates to the technical field of all-position pipe-to-pipe welding machines, in particular to a sealed all-position pipe-to-pipe welding machine. Background Art

[0002] The sealed all-position pipe-to-pipe welder is an advanced welding equipment designed for the docking of various pipe fittings. It adopts all-position automatic non-melting electrode argon arc welding, which has the characteristics of high welding quality and long continuous welding time. It is particularly suitable for welding thin-walled stainless steel, carbon steel, titanium and titanium alloy pipes. This welding machine has been widely used in electronics, chemical food, drinking water, air conditioning, medical equipment, instrumentation and other fields. The sealed all-position pipe-to-pipe welder makes the tungsten needle inside the welding gun perform 360-degree rotation welding during the pipe-to-pipe welding process. The advantage of the welding machine lies in its efficient, stable and beautiful welding effect. Its closed cavity design and unique argon ring diversion system ensure continuous and uniform argon protection around the weld during welding, thereby ensuring the stability of the arc and the beauty of the weld. However, the traditional sealed all-position pipe-to-pipe welder is not convenient for fixed-limit welding of pipes of the same size during welding, and manual pipe limit is required, resulting in low welding efficiency and certain disadvantages.
