Welding of two pieces of metal together with a butt weld can be carried out by different resistance welding processes. The butt weld consists of joining of two pieces of metal together either on face or on edge. It is of two types namely upset butt welding and flash butt welding. Type # 1. Upset Butt Welding: It is a [...]
In this article we will discuss about:- 1. Definition of Resistance Welding 2. Machines for Resistance Welding 3. Power Supply 4. Electronic Control. Definition of Resistance Welding: By definition, resistance welding is that process in which a sufficiently strong electric current is sent through the two metal pieces in contact to be welded which melts the metals by the resistance [...]
In this article we will discuss about:- 1. Definition of Arc Welding 2. Power Supply for Arc Welding 3. Arc Welding with DC and AC. Definition of Arc Welding: By definition, arc welding is that process in which the pieces of metal to be welded are brought to the proper welding temperature at point of contact by the heat liberated [...]
The following points highlight the five main types of arc welding. The types are: 1. Carbon Arc Welding 2. Metal Arc Welding 3. Atomic Hydrogen Arc Welding 4. Inert Gas Metal Arc Welding 5. Submerged Arc Welding. Type # 1. Carbon Arc Welding: Carbon arc welding differs from metal arc welding in that it is a puddling process and is [...]
The following points highlight the four main types of resistance welding. The types are: 1. Spot Welding 2. Projection Welding 3. Seam Welding 4. Percussion Welding. Type # 1. Spot Welding: By definition, spot welding is a form of resistance welding in which the parts or pieces are joined in spots, accompanied by heated relatively small sections of the parts [...]
