The quality of spot welding of Aluminum alloys largely depends upon the surface condition of the faying surface of the materials. Therefore, the surface treatment is usually required in order to remove natural oxide films, for obtaining good spot welding quality.
However, it has been said that the surface treatment contains many problems, such as, condition of laying surface, regulating the time up to the beginning of the welding after treatment, or control of treat solution, etc.
Thus, new spot welding machine, in that good welding quality can be obtained without preparatory surface treatment, is devised and constructed.
This report describes the process of studies have been made in designing this welding machine, also it gives some examples of the spot welding test results, or fabrication on Aircraft, from using this machine.
