A laser-welding maker serving several industries
United Winners Laser's official range covers laser sources and welding machines plus automation for batteries, cars, electronics and other sectors. This page deals with its battery module line; other products in the range would be quoted separately.
A Shenzhen government report dated 16 June 2023 names 深圳市联赢激光股份有限公司 and describes its business as precision laser welding and intelligent manufacturing. It is a dated record of a company visit and gives background on the business. Joint quality on your parts is shown by your own weld trial.
A laser-welding company with several production bases
United Winners Laser says it was founded in 2005, with its headquarters and R&D base in Pingshan, Shenzhen. It lists further manufacturing in Liyang, Jiangsu, and in Huizhou, where it describes a 65,400 square metre site opened in 2017, as well as a Japanese subsidiary set up in 2012. It also names several provincial and municipal laser-welding laboratories and engineering centres.
For battery buyers the relevant work is laser joining in cell and module production: tab welding, busbar welding and sealing welds. Joints, not laser power, decide weld quality, so ask for sectioned samples, pull or shear tests and resistance measurements on your own cells and busbars. The acceptance testing page shows where those checks fit into a factory test before shipment.
