Specific embodiment
Below in conjunction with Figure of description, the present invention will be further described.
Welding pliers of the invention, include two calipers 02 linked together by bearing pin 01 conventional pliers as shown in Fig. 1-2, each caliper 02 includes the binding clip 21 in front of bearing pin and the embedding handle 22 positioned at bearing pin rear, there is shear blade 211 on binding clip 21, the method have the characteristics that as shown in figures 5-13, binding clip 21 includes matrix 212, and shear blade 211 is welded on matrix 212 from cutting performance better than the material of binding clip matrix；Matrix uses the mass percentage content of carbon by the carbon steel of 0.35-0.65% is made, and the hardness of matrix is 30-55HRC, and shear blade is made of high-speed steel, and the hardness of shear blade is 58-66HRC.
Further, the carbon steel for being made matrix is the steel alloy less than 2.5% containing at least one of Cr, Mo, V alloying element and alloying element mass percentage content.
Preferably, matrix uses the mass percentage content of carbon by the carbon steel of 0.40-0.60% is made, and the hardness of matrix is 40-50HRC.The carbon steel for being made matrix is the steel alloy less than 1.6% containing at least one of Cr, Mo, V alloying element and alloying element mass percentage content.
