First, the most important characteristics of laser beams and the available high-power laser types for welding purposes are presented. Then, several methods of welding with electric arcs are described in detail. Finally, various ways of combining electric arcs with laser beams to hybrid laser-arc processes are shown.enwelding heat sourcelaser beamelectric arclaser beam weldingarc weldinglaser-arc weldinghybrid welding621671book article
