Excuse me, where is the place to weld aluminum alloy in Changchun? Thank you.

Changchun Bus Equipment Co., Ltd. in Changchun City, where the EMU is manufactured, all their car bodies are made of aluminum alloy. If you need to process and weld the workpiece, just contact their welder. All by private work. Their welding level can completely convince you, because their welders have obtained international welding qualifications, and welding aluminum alloy car bodies is not allowed without qualifications. All trained by Germans. The welding teacher who trained them is Guo Sen, also called Hou Gen, both of whom are German transliteration teachers.
