The CTBA(Coupled torsion beam axle) of automotive rear chassis parts connects to trailing arm which assembled on the rear axle by whelding process and achieves a task of absorbing torsion from wheel when automobile pass through the curves. In the welding process between CTBA and trailing arm, the welding deformation of trailing arm which connected to wheel hub axle module occurs, and it can effect to tow angle, camber angle, and caster of the wheel axle. Thus, the welding deformation should be controled strictly. In this paper, the welding process between CTBA and trailing arm was analyzed by FEM(Finite Element Method), the effect of welding time, temperature after welding process, clamping time and cooling time was grasped, and phase transformation after welding process was analyzed to minimize the after-machining(milling) of the welding part.
