Flange welding deformation controlgear

The utility model provides a flange welding deformation controlgear, including oil pressure system, cooling system, welding spare clamping mechanism, welding clamping mechanism is including location copper dish, hold -down mechanism, cooling system by freezing location copper dish and flange reduce flange heat altered shape, and the common supported flange of oil pressure system and clamping mechanism is controlled its and is warp, and the step that sets up is gone up to location copper dish provides anti -deformation the space for the flange that compresses tightly, three kind above -mentioned control effects stack, make the flange welding after strain flow control within 0.4mm, ensure that the assembly product reaches the gas tightness requirement after the assembly, reduce the complicated process of carrying out plane degree processing to the fitting surface in flange welding back, the utility model discloses combine with process such as mechanical manual spin welding, the welding arc light radiation sched
