Hybrid Laser Arc Welding (1 PDH)

The development advances in continuous fiber power laser technology are bringing hybrid laser-arc welding (HLAW) into the twenty-first century. Although the use of laser radiation and electric arc together for welding of metals and alloys so that both sources of heating influence on a material within just one heating zone was developed over thirty years ago, these recent advancements have increased both the quality and the accuracy of the HLAW process. This paper covers the theoretical base of laser and hybrid welding; design of technological equipment for the hybrid process; and the peculiarity of metal structure formation in hybrid welding.
