Stainless steel welding methods and skills

2018-04-25 03:12:02

The length of manual welding arc is adjusted by the human hand, submerged arc welding is suitable for stainless steel plate with medium thickness or more, gas welding is convenient and flexible, and can weld welds in various spatial positions. Argon arc welding is better for stainless steel.

Tools/Materials
1

Manual welding

2

Submerged arc welding

3

Gas welding

4

Argon arc welding

Methods/Steps
1

Manual adjustment The length of the manual welding arc is adjusted by the human hand, which determines the size of the gap between the electrode and the workpiece, and when used as an arc carrier, the electrode is also a filler material for the weld.

2

Submerged arc welding is suitable for the welding of stainless steel plate (6~50mm) with medium thickness. The submerged arc welding has high productivity and good weld quality, but it is easy to cause segregation of alloying elements and impurities.

3

Gas welding is convenient and flexible, and can weld welds in various spatial positions. For some stainless steel parts such as sheet structures and thin walls, gas welding can sometimes be used without corrosion resistance requirements.

4

When stainless steel is welded with argon arc welding, due to the good protective effect, alloying elements are not easy to burn, and the transition coefficient is high, the weld is formed well, there is no slag shell, and the surface is smooth, so the welded joint has high heat resistance and good mechanical properties.
