The invention provides a corrosion-resistant lock rod steel pipe forming process. The corrosion-resistant lock rod steel pipe forming process comprises the following steps that 1, a steel plate roll is discharged through an unwinding mechanism; 2, the two sides of a steel plate are milled by an edge milling machine, and the preset plate width and the groove shape are milled out; 3, the steel plateis pre-bent to the preset curvature by a pre-bending machine; 4, the pre-bent steel plate forms a tubular structure through a steel pipe forming machine, and a forming welding pipe is welded througha laser welding device; and 5, the cooled welding pipe surface is coated with an anti-corrosion coating through a spraying device. By the adoption of the corrosion-resistant lock rod steel pipe forming process, the corrosion resistance of a container lock rod is improved, and the reliability of a lock rod device is improved. 本发明提供了一种耐腐蚀的锁杆钢管成型工艺，包括以下步骤：步骤一：钢板卷通过放卷机构进行放料；步骤二：铣边机对钢板两侧进行铣削，铣削出预设的板宽和坡口形状；步骤三：预弯机对将钢板预弯至预设曲率；步骤四
