Laser-welded the damaged top of this copper alloy core. he could weld copper and aluminum alloys more easily. These machines have been instrumental in helping MTW become a leader in micro-laser welding. Due to the increased volume of work the company realized after the purchase of the 200-watt welder—and the quality, performance and customer service O.R. Laser provided—MTW has since purchased two more laser welders. "Using the most advanced laser welders has allowed us to achieve minimal to undetectable weld sink and distortion," Mesick says. "And the laser movement is mechanical, making it capable of providing a straight and consistent weld bead profile." Additionally, Mesick notes that these machines offer the ability to weld close to standing features without damage to surrounding areas; and the laser technician is able to deposit weld uniformly and accurately. And when it comes to necessary machine service, O.R. Laser quickly responds, Mesick maintains: "Like anything you own, there comes a day when some kind of service is needed. O.R. does whatever it can to service the machines. If I have trouble and an O.R. technician is available, he will drive or fly to Erie to fix the machine. I tell him what is wrong, and he has a general idea of what it could be. This knowledge enables him to narrow down the problem and select the appropriate part to bring with him. Then when he diagnoses the problem on site, he has the parts on hand to fix it." Laser-focused on the Future Business has exploded since Mesick added the 300-watt machine, and his experience with micro-TIG welding helped him pick up the new technology quickly and impart that knowledge onto his employees. "I was already working under a microscope, and the wire that I am using is the same wire," he explains. "The only thing that is different is the application: laser light vs. electrode elec- Laser-welded the ribs of a copper alloy core. tricity. It has been easy for me to pass this knowledge onto my team. The average learning curve is typically less than an hour. If you are experienced, you can pick it up even quicker. It all depends on the individual. There are crosshairs when you look through the lens and you can pinpoint the area that needs to be welded, and you just lay the wire right down by the crosshairs and hit the foot control." And because the machine is portable, it can be rolled right up to the part, if necessary. The faster laser machine allows MTW to turn work around quicker without sacrificing quality. "Quality is number one to my customers," Mesick says. "Speed is their number two concern, and price is third. This machine is high-quality." According to Mesick, MTW's work speaks for itself, and the fact that 90 percent of the work comes from out of town is proof. Mesick plans on adding another employee in the near future as well as another machine, once the economy is more stable. "It is a big purchase, but a definite one. O.R. Laser's equipment has enabled my business to expand and stay competitive." VIDEO: Micro Laser Welding and Micro TIG Welding short.moldmakingtechnology.com/mtw FOR MORE INFORMATION: O.R.
