The Plasma-Arc & Laser Hybrid Welding Technology combines conventional and laser machinery to produce a highly economic welding source.
High Power Lasers were introduced for industrial applications in the early seventies, replacing arc processes for cutting, welding, drilling, and coating. The high power laser market is a rapidly growing market, yet lasers have captured only a fraction of the arc market: while arc processes are typically of low initial investment and high energy efficiency compared to lasers, the drawbacks are poor controllability, limited depth of penetration, limited processing speed, and limited quality which results in expensive post-processes. Lasers offer higher processing speeds, and superior quality as well as high controllability. However, they require a high initial investment, and are energy inefficient.
The concept underlying dual technology is to combine the advantages of both sources: utilizing the cheaper plasma source to provide the bulk of the processing power, the combination and interaction with a laser source results in a new, combined discharged, with controllability, speed, and quality comparable to laser processing.
