Laser welding is a laser beam fusion material with high energy density. It has the advantages of fast welding speed, high strength, narrow welding seam, small heat impact zone, small deformation of workpiece, less work load and high flexibility. Laser welding can not only weld common carbon steel and stainless steel, but also weld materials such as structural steel, aluminum, copper and other metals which are hard to weld, and can weld various forms of weld.
The requirements for the quality of the welding strength and the appearance effect of the modern sheet metal processing are becoming higher and higher, especially the high added value and high requirements for the welding quality, which can be done without further processing or very little subsequent processing. Because of the huge heat input, the traditional welding methods will inevitably bring about distortion and distortion of the workpiece. In order to compensate for the deformation of workpiece, a large number of subsequent processing methods are needed to increase the cost.
Laser welding has a small heat input, minimal heat affected zone, significantly improving the quality of welding products, and reducing the subsequent work time. In addition, the welding efficiency and stability can be greatly improved due to the fast welding speed and the wide ratio of welding depth to width. Therefore, laser welding is becoming more and more popular in sheet metal processing.
Laser welding: a two - one tool
In modern sheet metal processing, different products require different quality requirements for welding strength and appearance effect. For example, the appearance of elevators, Kitchenware and food equipment needs beautiful, smooth and non distortion welding effect. However, some internal structural parts or subsequent parts need to be sprayed have higher requirements for welding strength and welding speed. This can reflect the advantages of laser welding, because the laser welding can not only realize the heat conduction welding of the welds, but also the deep welding of high welding strength and high welding speed.
