Hybrid laser arc welding (HLAW), a term that has been used for many years, is often associated with adding a gas metal arc welding (GMAW) process that trails behind the laser beam. Hot wire laser is a process that combines a preheated wire with a large-width laser beam. Hybrid laser welding encompasses both HLAW and hot wire laser as they are both ways to create a hybrid process with the laser beam, although the former uses an arc while the latter does not. Each process has specific benefits, which are discussed be..
