Standardized operation and precise forming establish a stable and reliable chassis welding process system.

This production line specializes in manual welding manufacturing of motorcycle and electric vehicle frames and sub-assemblies. It serves as a core process carrier ensuring overall vehicle structural strength and key dimensional accuracy.

The line follows a process-oriented layout of “sub-assembly pre-installation – main frame integration – post-weld treatment”. Based on dedicated rigid fixtures for positioning, it integrates manual MAG/MIG arc welding, spot tack welding, stud welding, post-weld straightening, and dimensional inspection stations, enabling full-process machining from tubes or stamped parts to complete frame assemblies.

Considering the complex spatial structure, thin wall thickness, and high sensitivity to welding deformation of two-wheel vehicle frames, a segmented symmetrical welding process and high-rigidity anti-deformation fixtures are adopted. This effectively controls welding distortion and ensures critical dimensional accuracy and weld joint strength at key points such as the front fork head tube and rear swingarm mounting positions.

The entire line implements standardized operation management with complete process documentation and safety protection systems, ensuring stable and controllable production while supporting flexible manufacturing of multi-model and multi-batch frame production.
