type laser pointer is relatively bigger

As the balance of heat input is low, high precision, can reduce reprocessing costs. In addition, the dynamic transfer of laser welding costs are relatively low, can reduce production costs. Easy to automate and fine positioning of the beam intensity can be effectively controlled. Deep penetration of laser equipment. Deep penetration of laser generally used continuous wave CO2 laser, these lasers can maintain a sufficiently high output power, resulting in "holes" effect, penetration throughout the workpiece cross-section to form a tough welded joints. The volume of torch type laser pointer is relatively bigger.
The laser itself, it can produce just as a heat source, a good parallel to the beam direction of the device. If it is oriented and effective treatment of the workpiece after the shooting, the input power to a strong compatibility, so that it can better adapt to the automation process. In order to effectively implement welding, laser and other necessary optical, mechanical and control components together to form a large welding system. The system consists of laser, beam delivery components, the workpiece handling and mobile devices, as well as control devices. This system can be only manually by the operator simply moving and fixed parts, including parts can also be automatically loaded, unloaded, fixed, welding, inspection. The system design and implementation of the total requirement is to secure a satisfactory weld quality and high productivity. Laser welding of steel materials. Ordinary carbon steel and alloy steel laser welding. In general, the good effect of laser welding carbon steel, the welding quality depends on the impurity content. The same as other welding processes, sulfur and phosphorus are the welding crack sensitive factors. In order to obtain a satisfactory weld quality, carbon content exceeds 0.25% needs to warm up. When different carbon steel welded with each other, the welding torch can be a little biased towards low-carbon material side, to ensure joint quality. The technology development of laser pointer has been finished.
Low-carbon rimmed steel as sulfur and phosphorus content, not suitable for laser welding. Low-carbon killed steel due to low impurity content, welding results are good. Medium and high carbon steel and ordinary steel can be a good laser welding, but need to preheat and post weld treatment to eliminate stress, to avoid crack formation. Laser welding of stainless steel.
