Copper clad metal strip with aluminum instead of copper power system was increasing, and then appeared at the contact between aluminum and copper due to corrosion caused by poor contact, fever, sparking, and even lead to increased resistance equipment accidents, increased maintenance times, affect the safe operation of other undesirable phenomena. 
If aluminum is used in the joints - copper clad  aluminum transition joints, which can effectively solve the above problems. At present, the commonly used aluminum on the market - the copper transition joints to flash welding products mostly. However, due to the complexity of the flash welding process requires large equipment, resulting in high production costs, the narrow scope of the problem. Based on this situation, referring to the company's advanced experience at home and abroad, using advanced welding technology rolled explosive welding technology successfully developed aluminum - copper transition joints.
