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.

The equipment is suitable for the welding of 1XXX~8XXX series of aluminum alloy materials, and can complete single-sided friction stir welding of aluminum alloy plates or profiles with a thickness of 2-30mm, a width of ≤3000mm, and a length of ≤4000mm. In addition, the equipment is equipped with a special heavy-duty A-axis swing system for medium and thick plates, which can realize any angle adjustment within the range of ±30° on the A-axis, can realize the welding of flat straight welds and spatial bevel welds. The equipment can be applied to mass production.
