DIN17100 St37-2 steel plate weldability and related welding processes

DIN17100 St37-2 steel plate has good weldability and is suitable for conventional welding processes. Here are some common welding processes associated with them:

1. Manual arc welding: suitable for small batch production, simple to operate, and able to meet general welding requirements.

2. Gas shielded welding (MIG/MAG welding): The welding area is protected by inert gas or active gas, suitable for high-speed welding and thicker steel plates.

3. Arc welding: A layer of specific alloy is coated on the surface of the base material. Under the action of the arc, the alloy melts and fuses with the base material to enhance wear resistance and corrosion resistance.

4. Submerged arc welding: By placing the welding rod under the weld, the welding environment is protected during the welding process, and it is suitable for efficient welding of large structural parts.

5. Plasma arc welding: Using plasma arc to heat and melt metal, it is suitable for situations where high welding quality requirements are required.

6. Laser welding: The laser beam is used to melt the metal on both sides of the weld, which is suitable for occasions that require high welding accuracy and speed.

7. Friction stir welding: Heating the material through mechanical friction, then stirring to melt part of the material and completing the welding.

8. Friction stir welding: Use friction heat and mechanical stirring to melt and connect the welding interface.

Selecting the appropriate welding process depends on factors such as the specific application, material thickness and requirements. When welding DIN17100 St37-2 steel plate, attention needs to be paid to controlling the welding parameters and selecting appropriate welding materials and filler materials to ensure welding quality and connection strength.
