45#钢作为中碳结构钢,具有良好的综合力学性能,并且广泛的用于制造高强度的运动杆件零件上,但由于是运动构件,承载着交变载荷,难免会产生缺陷进而需要补焊处理。本文着重对补焊方法进行描述,并通过具体实例加以分析,为其他构件补焊做参考。 45 # steel as a carbon structural steel, has good mechanical properties, and is widely used in the manufacture of high-strength parts of the moving rod, but because of the movement of components, carrying alternating loads, it will inevitably produce defects and then need to make up Welding treatment. This article focuses on the method of welding repair described, and through specific examples to be analyzed for the welding of other components for reference.
