Description

Technical Field

[0001] This invention relates to the field of industrial pipeline welding technology, and in particular to a welding device for industrial pipeline installation. Background Technology

[0002] Plasma arc welding is a precision welding technology that uses a plasma arc as a heat source. The plasma arc obtains higher energy density, temperature and stability by compressing the electric arc. The core relies on the plasma gun to constrain the electric arc into a slender arc column. The ionized gas forms a high-temperature plasma that impacts the welding base material. This technology is an upgrade and improvement of ordinary argon arc welding. It makes up for the defects of traditional arc welding, such as energy dispersion, poor weld formation and insufficient precision. It can realize micro-penetration deep welding of thin-walled parts and precision components, and is suitable for refractory metals such as stainless steel, titanium alloys and high-temperature alloys.

[0003] Chinese Utility Model Patent Publication No. CN211331739U discloses a welding device for industrial pipe processing, comprising a body. A quick-connect plug is provided at the bottom of the front surface of the body. A connector is inserted into the port of the quick-connect plug. A baffle is provided on one end of the connector, and a rectangular hole is formed on one end of the baffle. A support column is provided inside the rectangular hole, and the support column fixes the surface of the body. This utility model utilizes a designed baffle that blocks the connector at its end after insertion, thereby limiting the connector and ensuring it will not detach from the quick-connect plug under tension. This ensures more stable and reliable use. The designed support column supports the baffle, and the designed connecting rod facilitates the installation and support of a spring.
