Heavy-duty Dynamic Gantry Friction Stir Welding Equipment was successfully delivered to the customer

The heavy-duty dynamic gantry friction stir welding equipment, which was independently developed and designed by Aerospace Engineering Equipment (Suzhou) Co., Ltd. (hereinafter referred to as “AEE”), was recently packaged and delivered to customers in the rail transit field: Quality supplier of Zhuzhou Lince Group Co., Ltd. — CRRC Zhuzhou Locomotive Co., Ltd.

This equipment is mainly used for the welding of traction beam and sleeper beam in rail transit field. It is helpful to solve the problems of large welding distortion, low performance, multi-lager and multi-pass welding in traditional aluminum alloy fusion welding of medium and thick plates, and effectively improve the welding quality and welding efficiency.
