HLAW combines best attributes of laser welding with those of conventional arc welding. Research related to this area is in fancy stage. Understanding of process phenomena, appropriate selection and precise control of process parameters may yield favorable high quality weld with respect to bead geometry, mechanical metallurgical characteristics of the weld and HAZ. Apart from process modeling, simulation and parametric optimization, thermal aspects of this technique including interference of two different heat sources affecting weld quality, phase change and solidification phenomena are also important which need to be investigated thoroughly. The paper highlights challenges of Hybrid Laser Arc Welding (HLAW); prior state of art and future scope of work.

Abstract


HLAW combines best attributes of laser welding with those of conventional arc welding. Research related to this area is in fancy stage. Understanding of process phenomena, appropriate selection and precise control of process parameters may yield favorable high quality weld with respect to bead geometry, mechanical metallurgical characteristics of the weld and HAZ. Apart from process modeling, simulation and parametric optimization, thermal aspects of this technique including interference of two different heat sources affecting weld quality, phase change and solidification phenomena are also important which need to be investigated thoroughly. The paper highlights challenges of Hybrid Laser Arc Welding (HLAW); prior state of art and future scope of work.
