一、纤焊作业的主要影响要素钎焊刀具一般都是钎焊刀片后再经刃磨加工而成。然而,钎焊时如残留有内应变,就会在刃磨时易于产生裂纹,即使在刃磨时不产生裂纹,但这内应变也会使刀具在使用初期易于损坏,刀片脱落,产生裂纹,降低刀片使用寿命,而不能充分发挥硬质合金和金属陶瓷等的特长。影响钎焊作业的主要要素有: (1)刀体和刀片(材质、外观形状、钎焊部形状)。 (2)钎(焊)料(熔点、钎焊强度、焊
First, the main elements of the role of welding operations Brazing tools are generally brazed blades and then by grinding processing. However, if there is residual strain during brazing, it will be easy to crack during sharpening. Even if there is no crack during sharpening, this internal strain will cause the tool to be easily damaged in the initial stage of use, the blade will fall off and produce cracks, Reduce blade life, but can not give full play to the advantages of cemented carbide and cermets. Affect the main elements of the brazing operations are: (1) body and blade (material, shape, braze shape). (2) Brazing (welding) material (melting point, brazing strength, welding
