为减少废品率,研究用冷焊加焊后回火处理的工艺方法来焊补缸体、缸盖铸造缺陷,试验结果表明,其补焊区域加工性良好,能满足产品技术性能要求。
In order to reduce the reject rate, the cold welding and the post-welding tempering process were used to weld the defects of the cylinder block and cylinder head casting. The test results showed that the workability of the welding repair area was good and the technical performance of the product could be met.
