This thesis by TIG Welding process on copper and steel welding of dissimilar materials, As copper and steel welding of dissimilar material for the development of theoretical basis and experimental basis.

(1)Copper and steel of physical properties and chemical composition varies greatly, copper steel weld is easy to produce a lot of defects such as cracks, pores fussion, etc, but as long as the implementation of reasonable welding process, welding operations technical mastery, will still be able to obtain satisfaction of copper-steel welded joints.

(2) Through welding inspection, welds with good performance, and prove that welding process and its arguments are reasonable.

(3)Metallographic examination, the internal organization of uniform welds; copper and copper alloy uniform, combined with the zone of transition; copper and steel weld line straight, no holes, and Cu And Fe Each other to a certain extent, the fusion zone for metallurgical combine.
