[0002] Generally, saw blades need to be tested with a hardness tester after heat treatment and welding. The base testing of saw blades and the welding strength testing of the tooth back of circular saw blades after welding are particularly important. Hardness testing plays an absolute guiding role in guiding the adjustment of welding process and the process guidance of tempering after welding.

[0003] Since the hardness of the saw blade needs to be sampled at different positions during the hardness test, and the hardness of different saw blade thicknesses needs to be controlled, and the hardness of special saw blades such as planer blades and boss saw blades needs to be controlled, generally only the hardness near the center hole can be detected, and other positions cannot be accurately detected. Sometimes the saw blade will have its own torque measurement, which affects the detection accuracy; and the hardness after welding and welding tempering at the tip of the saw blade cannot be detected, making process control extremely difficult to achieve. The quality can only be controlled by the proficiency of the workers, the experience of the engineers, and the characteristics of the plate itself. It cannot be quantitatively controlled, resulting in uneven product quality.
