Laser Welding System
There are two types of lasers commonly used for industrial welding: gas lasers and solid state lasers. Gas lasers, often referred to as carbon dioxide lasers, use a mixture of CO2, helium and nitrogen. Gas lasers can cut and weld both metallic and non-metallic materials, though reflective metals are more easily worked if they are coated. Beam transmission is by mirror. Gas lasers are not suitable for fiber optics. Solid state lasers use use a solid bar of YAG (yttrium aluminum garnet) doped with neodymium. Solid state lasers can be used on all metals, including reflective metals, but cannot cut or weld non-metallic materials. They can be used for fiber optic applications, and are generally considered to be more precise but slower than gas lasers. Both types can be used in either continuous or pulsed modes. All laser welding systems have the advantage of great speed and precision when compared to other methods. Their highly concentrated beam results in a small heat-affected zone, even in materials with low diffusivity. The computer control makes it easy to change formulations, resulting in greater flexibility. Laser welding systems are also easily automated, an especially important consideration when labor costs are a huge element in overall costs. At Custom Machines, Inc. we have extensive experience with both lasers and robotics. We can put together for you a laser welding system, automated or manually operated, that will address your specific processes, needs and problems. You'll be amazed at how quickly such a system will pay for itself in increased productivity and high quality products.
