摘　　要：文章主要研究在低碳钢与不锈钢这两种材料用炉中钎焊的方式进行焊接时,通过控制焊缝间隙、保温时间等工艺参数,对焊件进行金相分析、硬度试验,对焊缝进行分析,进而得出影响焊缝质量的因素,以及内部元素扩散得到的结果。通过试验所得的数据可证明,焊件在钎缝间隙为0.12mm时焊缝缺陷最少;通过硬度试验得出,焊件内部元素的相互扩散使扩散区域的硬度变强。The paper mainly studies the two materials of low carbon steel and stainless steel which used in the furnace brazing welding way. The metallographic analysis, hardness test and weld analysis of welding pieces are analyzed by controlling the welding seam clearance, heat preservation time and other process parameters. The factors affecting weld quality and the results of internal element diffusion are obtained. Through the test data, when the brazing gap is 0.12 mm, the weld defect is the least. The hardness test shows that the interdiffusion of the elements inside the welding pieces makes the hardness of the diffusion area stronger.
