Dimensional characteristics of welds performed on AISI 1045 steel by means of the application of high power diode laser
Keywords:laser welding, high power diode laser, shielding gas, carbon steel, depth of penetration
The named High Power Diode Laser (HPDL), emits a beam of optical energy generated by diode stimulation and offers the capability of supplying levels of power up to 6 kW. The objetive of this research work was to study the main welding variables and their effects on dimensional characteristics of the beads performed by means of application of this novel laser. The results obtained, show that HPDL, is an energy source able to perform welds on AISI 1045 steel plates under conduction mode, without any kind of mechanized preparation, preheating or post-weld treatment and, without filler metal application.
