摘要
大型铸钢件常见焊接缺陷有夹渣、气孔、咬边、裂纹等。本文针对常见焊接缺陷进行分析,结合生产实践提出改进措施,针对具体缺陷类型,从坡口角度设计、焊接工艺参数实施、焊材质量控制、焊前预热等方面进行重点控制,不断提高铸件焊接质量。
The common welding defects of large steel castings include slag,blowholes,undercuts,crack,etc.In this paper,the common welding defects were analyzed and the improvement measures were put fbrward.The welding quality of castings was continuously improved by the control of the groove angle design, welding process parameters, welding material quality and preheating.
