Circular-saw blades are equipped with hard-metal blades to increase their wear-resistance.
Up until now, component assembly has been carried out by means of induction soldering, which however, involves negative effects due to high thermal stress.
Using a special workstation developed by KUGLER, a laser-assisted soldering process divides the laser beam into two partial beams (twin optics), which are subsequently defocused and applied to both sides of the joining area. In this way, the joining area is heated up homogeneously, which reduces overheating.
Contrary to conventional inductive processes no effort is required for rework after thermal treatment or re-adjustment after soldering.
Conclusion:
Besides improving the mechanical properties of the saw blade, laser-beam welding considerably contributes towards reducing the overall manufacturing costs and at the same time increases the useful life by approx. 40%.
