Welding method of hot rolled medium and heavy steel plate

1. Arc welding
Arc welding is a good welding method for hot-rolled medium plate, but the equipment of arc welding is complicated, which is not suitable for practical operation under outdoor standard.

2. Resistance spot welding and wave soldering
This kind of welding method can be used to weld hot-rolled medium plate and thin pipe with thickness less than 5mm. However, the machine and equipment needed in welding are very complex, the welding current is large and the production efficiency is high, especially for the parts and components of mass production.

3. Single pulse argon arc welding machine
Single pulse argon arc welding machine can improve the reliability in the whole welding process, and adjust the main parameters to control the output power of arc and welding forming. The welding parts have small deformation and small heat affected zone. It is especially suitable for welding thin pipe, all position welding and forging pipe, hose and super hard pipe with strong thermal sensitivity.
