The most commonly used type of stainless steel welding is gas shielded welding.
Gas shielded welding
It is a welding method that uses gas as a protective layer, which can effectively prevent the influence of oxygen and nitrogen in the air on the welding quality. This welding method has been widely used in stainless steel welding due to its advantages of fast welding speed, stable quality, and low cost.
Classification of gas shielded welding
Gas shielded welding can be divided into melting electrode gas shielded welding (MIG/MAG welding) and tungsten inert gas shielded welding (TIG welding) depending on the gas used and the protection method. MIG/MAG welding uses inert gas or mixed gas as a protective layer, and the welding wire is fed into the molten pool through an automatic or semi-automatic wire feeding device for welding. It is suitable for welding parts with high density distribution. TIG welding uses anhydrous argon gas as a protective gas to heat the stainless steel electrode to a molten state, and then contacts it with the workpiece to form a weld seam, especially suitable for welding medium and heavy plates of plates and pipes.
Although TIG welding is a complex process with slow welding speed, high labor intensity, and high cost, it can provide high-quality welding results, so it still has a wide range of applications in stainless steel welding.
In addition, manual arc welding is also one of the traditional methods for stainless steel welding. It involves manually operating an arc welding gun for welding, which has high flexibility and adaptability and is suitable for workpieces of various shapes and sizes. However, the disadvantages of manual arc welding include slow welding speed, high requirements for welder skills, and significant human factors affecting welding quality.
Therefore, although manual arc welding is still used in certain specific situations, gas shielded welding has become the most commonly used type in stainless steel welding due to its high efficiency and stable quality.
