Stainless steel is a metal material with good corrosion resistance and high strength, which is widely used in the manufacturing industry. However, due to the special properties of stainless steel, its welding is difficult. Here are some of the most commonly used welding methods for stainless steel.

1.TIG (tungsten argon arc welding) welding method.

TIG welding is currently one of the most commonly used methods of stainless steel welding, it uses DC or AC power supply, through the tungsten electrode to guide the arc, under the protection of argon gas will be melted stainless steel material, and then use the filler metal to fill the molten pool to form a weld. This welding method can obtain high quality weld seam welding process heat input is small, can reduce the stainless steel discoloration, oxidation and other phenomena. However, TIG welding speed is slow, the operation of the technical requirements of higher.

2.MIG (metal inert gas shielded welding) welding method.

MIG welding is through the protection of inert gas (such as gas), the formation of an arc between the stainless steel and filler material, melt the material and form a weld.MIG welding speed, suitable for thicker stainless steel plate welding, operation is relatively simple. However, due to the gas protection, the welding environment requirements are high at the same time also easy to produce porosity and other defects in the welding process.

3. Resistance welding method.

Resistance welding is placed between the two electrodes of stainless steel, applying current through the stainless steel to produce heat to melt, and then pressurized compaction to form a weld. Resistance welding is fast, suitable for high-volume production, welding quality is stable. However, due to the need to apply current and high temperature heat, the welding process is prone to discoloration, oxidation and other phenomena.

4. Long bar arc welding method.

Long bar arc welding is a method of welding through the electrode. In the stainless steel caused by the arc discharge, so that the stainless steel melts and forms a weld. Long bar arc welding is suitable for larger thickness of stainless steel sheet welding, can adapt to higher welding speed, but the operation of the technical requirements of the higher arc stability is poor.

5. Laser welding method.

Laser welding is a method of rapidly melting stainless steel and forming a weld through the high energy of the laser beam. Laser welding speed, heat affected zone is small, high quality welding. However, the laser equipment is expensive, the operator requirements are high, and the welding process requires strict safety measures.

In short, the most commonly used welding methods for stainless steel include TIG welding, MIG welding, resistance welding, long bar arc welding and laser welding. In the choice of welding method, according to the nature of the specific workpiece requirements, thickness and other factors for comprehensive consideration, choose the appropriate method to ensure that the quality and efficiency of the connection.
