Tungsten carbide weld material to be formed has sufficient plasticity so that the solder itself by plastic deformation of the stress relief part of the welding; appropriate melting point of solder, weld metal is lower than the melting point of at least 40 ° to 60 ℃ but requires higher than the operating temperature of weld 300 ℃, this way you can ensure that the tool can work in high-speed cutting time. Under the conditions allowed, should try to reduce the melting point of the solder to reduce heat stress and deformation welding carbide cutter body because heat generated. Due to uneven heat distribution, rapid heating and rapid cooling of the alloy may also produce significant transient stress. Rapidly heated, subjected to a tungsten carbide cutting tools outer layer stress, the intermediate layer is subjected to a tensile stress.
