Are there any restrictions on the thickness of the steel plate, such as the minimum thickness of the steel plate?
If the intensity is enough, you should be the first 4mm for the economy. Carbon steel plate, with electrode arc welding, 2 diameter welding electrode on line.If it is stainless steel, tungsten argon arc welding is better
No minimum, no maximum, no requirements, what kind of plate can be welded, but the welding method is not the same as welding equipment.
The information of the building is incomplete and can not be determined. The welding technical parameters will affect the welding method, welding current, welding voltage, welding environment and specifications
