Description

Technical Field

[0001] The utility model belongs to the technical field of argon welding, and in particular relates to a rotary surround type argon welding machine. Background Art

[0002] Argon welding, also known as argon arc welding, is a welding technology that uses argon as a shielding gas. It is also called argon gas shielded welding, which means that argon shielding gas is passed around the arc welding to isolate the air outside the welding area to prevent oxidation of the welding area. The chlorine welding machine is a machine that uses argon arc welding and adopts a high-voltage breakdown arc starting method. Argon arc welding, also known as tungsten inert gas shielded arc welding, refers to a welding method that uses industrial tungsten or active tungsten as a non-melting electrode and argon gas as a shield. It is referred to as TIG and is generally used for thin plate welding and thick plate single-sided welding and double-sided forming backing welding.

[0003] The prior art discloses a rotary surround argon welding machine with patent announcement number CN217913336U. The patent includes a main body limiting mechanism, an annular welding mechanism and a threaded disassembly mechanism. An annular welding mechanism is arranged on one side of the main body limiting mechanism, and a threaded disassembly mechanism is connected to the back of the main body limiting mechanism. The rotary encircling gas welding machine, after fixing a tubular object such as a steel pipe by a limiting frame, can be used through a carrying seat arranged on two groups of annular frames, and a ring-shaped sliding structure formed by the carrying seat through a cylinder and the annular frame, so that the carried welding head performs an encircling welding process on the annular range of the annular frame. During welding, the connecting screws can also be screwed out from both ends of the carrying seat to separate the connecting plate from it, so that the user can use it alone by hand to perform other welding processes, or replace welding joints of different sizes for welding operations, thereby improving the flexibility of use. In this way, errors caused by hand-held welding are avoided, and the welding quality and efficiency are improved. However, the following deficiencies still exist in actual use: From a practical point of view, in the patent, when welding pipes of different specifications and sizes, it is necessary to disassemble and replace the limiting frame for fixing. This work process is repetitive and cumbersome, inconvenient to use, and reduces the convenience of using the device. At the same time, when performing annular welding through the annular frame, the distance of the welding head cannot be adaptively adjusted for welding, which leads to inconvenience in operation during welding work and welding errors.

[0004] Therefore, a rotary surround argon welding machine is needed to solve the problems in the prior art that the adjustable fixed installation cannot be quickly performed according to the size of the welding pipe and the distance between the welding head and the welding part is not convenient to adjust.
