Laser Cladding of Copper Alloys on Steel

Аннотация

The paper discusses the process of welding copper-based powder on samples of steel 40 Kh by radiation of a continuous CO₂ laser. It is shown that the friction coefficients are 0.014–0.021 for samples cladded by a scanning beam, which is lower by a factor of two than for samples of cast bronze. The effect of transverse beam oscillations on the quality and performance of the cladding process is studied. It is shown that, for a beam scanning frequency of 220 Hz, the cladding performance increases by a factor of 1.5.
