Welding method for prefabricated pipe of pipeline workstation

First, TIG welding

TIG welding is a manual welding method with high quality and high efficiency. It uses a tiny tungsten rod to generate an arc welding spark, while inert gas (such as argon) is used to protect the welding area, and a filler metal strip is used to fill the weld.

TIG welding is a high-precision welding method that is suitable for a variety of metals, including materials such as stainless steel, copper, aluminum and titanium. Its welding speed is slow, but very fine welds can be obtained with almost no oxidation or other contaminants.

Two, MIG/MAG welding

MIG/MAG welding is a semi-automatic welding method that can quickly weld a large number of pipes. It uses metal aluminum wire or steel wire to fill the weld while inert gas is used to protect the weld area.

MIG/MAG welding is suitable for welding various metals, including steel, aluminum and copper. Its welding speed is very fast, and large pipes can be welded quickly. At the same time, it can also get better welding quality, but for smaller welding areas (such as energy saving clips, etc.), MIG/MAG welding may not be suitable.

Three, arc welding

Arc welding is a manual welding method, and it is also a common welding method for prefabricated pipelines in pipeline workstations. It uses a fusible welding core that melts the surface of the core and the substrate through an electric arc, so that the core and the substrate solidify into a weld.

Arc welding is suitable for a variety of metals, including steel, copper, aluminum and nickel. It is not only suitable for pipelines under high pressure, high temperature and high corrosion environment, but also can weld pipes of various shapes. However, there are certain differences in the welding quality of arc welding, which requires skilled workers to master welding skills.

【 Conclusion 】

There are many welding methods for prefabricated pipes in pipeline workstation, among which TIG welding, MIG/MAG welding and arc welding are the three common welding methods. Each welding method has its applicable occasions and non-applicable occasions, and it is necessary to choose the appropriate welding method according to the needs in actual production. At the same time, reasonable use of various welding skills to ensure welding quality and safe production is the basic requirements of pipeline workstation prefabrication pipeline construction.
