| HYBRID LASER WELDING |
 |
ATS originally began research into hybrid laser welding to provide affordable, lightweight, precision structural shapes for shipbuilding. Our patented system combines laser welding with a gas-metal arc welding (GMAW) system, greatly reducing thermal distortion. The ATS hybrid system provides superior travel speeds, improved metallurgical properties,  better tolerance to fit-up variations (especially gaps), reduced distortion, better final weld contour, and improved structural fatigue life. We also developed a unique process control and quality assurance (PC/QA) system to adapt process weld parameters and perform on-the-fly inspections of weld size, porosity, undercut, and other quality attributes.
Our innovative, semi-automated system uses a series of cameras to both guide the welding process and inspect the weld during and after completion. This capability enables the user to manufacture products at higher speeds and with greater reliability and repeatability than previously possible. ATS has participated in multiple weld qualifications for the HLAW process from the U.S. Navy, ABS and AWS. |
