The welding process and welding method are related to other factors, and the operation should be determined according to the material, grade, chemical composition, welding structure type and welding performance requirements of the welder.

First of all, it is necessary to determine the welding method, such as manual arc welding, submerged arc welding, GMAW and so on. There are many kinds of welding methods, which can only be selected according to the specific situation. After the welding method is determined, the welding process parameters are formulated. The types of welding process parameters are different. For example, manual arc welding mainly includes: electrode type (or brand), diameter, current, voltage, welding power supply type, polarity connection, welding layer number, pass number, inspection method, etc.
