1.焊接法点焊早在十年前就引入自动化加工业,至今已被广泛应用。该法简单、经济、可靠,费用通常很少。采用功率为10～20W的中小型激光器和光束导向、光束传输装置,每小时可焊100(沁个点。采用中、小功率激光器还可进行脉冲式缝焊。 1. Welding spot welding as early as ten years ago, the introduction of automated processing industry, has been widely used. The method is simple, economical, reliable and usually costs very little. The use of small and medium-sized laser power of 10 ~ 20W and beam-oriented, beam transmission device, welding per hour can be 100 (Qin points. Medium and low power laser pulse welding can be carried out.
