The effect of the laser spots overlap on the structure during square parts quenching of 1.1191 steel
Original language description
Laser technologies are among the unconventional methods of heat treatment and machining. Among the biggest advantages of laser quenching (hardening), it can be included high speed and process efficiency, a narrow thermally affected area and the possibility of processing complicated parts in shape that could not be workable with common conventional methods. During laser quenching of large surface parts, it is necessary to solve the problem of mutual overlap of laser spots. There is an unquenched area when insufficiently overlapped; with a large overlap, it can occur a tempering of the already quenched belt. Both cases negatively influence the resulting structure and mechanical properties. This article deals with finding the optimal degree of point laserspot overlap to ensure a high-quality quenching of large surface parts and with setting appropriate quenching parameters.
