摘　　要：在高频焊接过程中,焊接温度和焊接时间是影响PCD复合圆锯片焊接质量的两个重要因素,焊接温度过低和焊接时间过短会降低焊接强度,而焊接温度过高和焊接时间过长会导致PCD复合片的石墨化以及出现“过烧”的现象。通过实验对比在焊接温度580℃、620℃、660℃和700℃条件下,采用300 mm/min、250 mm/min、200 mm/min、150 mm/min的送丝速度来控制焊接时间,设定每齿的焊接送丝长度为12 mm,从而对比不同工艺下的焊接强度,得出采用焊接温度660℃、送丝速度150 mm/min的焊接工艺能够达到最高的焊接强度。In the process of high frequency welding,welding temperature and time are two important factors to affect the welding quality of PCD composite circular saw blade.Too low welding temperature and too short welding time will reduce the welding strength.However,high welding temperature and long welding time will lead to graphitization and"overburning"of PCD composite sheet.For the experimental condition of the welding temperature at 580℃,620℃,660℃and 700℃,the wire feeding speed of 300 mm/min,250 mm/min,200 mm/min and 150 mm/min is used to control the welding time,and the welding wire feeding length of each tooth is set to be 12 mm.According to the comparison of the welding strength under different processes,it is concluded that the welding process with the welding temperature 660℃and wire feeding speed 150 mm/min can achieve the highest welding strength.
