| 摘 要： | 由于焊接变形具有诸多危害,为保证产品理论尺寸及控制其精度,文章通过选择合适的焊缝形状和尺寸、合理的焊接顺序和工艺参数、刚性固定法以及反变形法对车架焊接变形进行控制,最终将变形控制在合理范围之内,使产品满足装配要求。虽然焊接变形具有不可预测性,但只要掌握其规律并采取相应措施,就能很好地加以控制。

Control Methods of Welding Deformation in the Process of Automotive Frame Welding |

| Abstract: | As many hazards of welding deformation,in order to ensure product theoretical size and control its accuracy,welding deformation of frame welding is controlled by choosing appropriate weld shape and size,rational welding sequence and process parameters,rigid fixing methods and reverse deformation.And eventually deformation is controlled in the reasonable scope,the product is met the requirements of assembly.Welding deformation is unpredictable,but its regularity is mastered and take corresponding measures,welding deformation can be controlled better. |
