利用电焊机电弧钎焊硬质合金刀片,既简单又经济,能保证刀具使用寿命,提高生产效率。在一些焊刀设备条件差的机修厂,能及时解决问题。选用一般电焊机,调至小电流挡(70—80A),取手电池(即1号电池)中碳棒两根(有条件可用电影座机用弧光碳棒或其它粗细相当的碳棒),一根夹在电焊钳上,地线上设法接一焊钳夹持另一根碳棒,两碳棒相接触产生电弧,保持两碳棒间隙,以稳定电弧,用此热量焊接硬质合金刀片。其工艺如下:
The use of electric arc welding brazing carbide blade, both simple and economical, to ensure tool life, improve production efficiency. In some bad welding equipment repair shop, can solve the problem in time. Selection of general welding machine, transferred to a small current block (70-80A), take batteries (ie battery No. 1) in the two carbon rods (conditional available landline carbon or other equivalent carbon rod), a Clip on the welding clamp, the ground trying to take a welding clamp to hold another carbon rod, the two carbon rods contact arc, maintaining two carbon rod gap to stabilize the arc, with this heat welding carbide blade. The process is as follows:
