The welding process is related to the welding method and other factors. During operation, it shall be determined according to the material, brand, chemical composition, structure type and welding performance requirements of the weldment.
First of all, it is necessary to determine the welding methods, such as manual arc welding, submerged arc welding, tungsten argon 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 model (or brand), diameter, current, voltage, type of welding power source, polarity connection, number of welding layers, passes, inspection method, etc.
