Depending on the type of material on which welding will be applied, it is considered as metal welding and plastic material welding.
Our area of interest is metal welding. So what is metal welding?
Combining metallic material using heat or pressure or both, and with or without adding a material of the same type or with the same or approximate melting range, is called metal welding. If an additional material is used to join two parts, this material is called filler metal.
