With the rapid development of welding technology and the continuous improvement of laser welding machine equipment, and laser welding technology promotes all engineering application materials to realize laser welding. The advantages of laser welding machine technology replace the traditional welding technology. What are the differences between laser welding machine and traditional welding equipment?
Firstly, the traditional resistance welding is applied to welding thin metal parts, clamping the welded parts between two electrodes, melting through large current and the surface contacted by the electrodes, that means welding is carried out through the resistance heating of the workpiece. The disadvantage is that the workpiece is easy to deform, and the resistance welding needs to be welded on both sides of the joint.
The laser welding machine only operates from one side. The electrode used for resistance welding needs regular maintenance to remove oxides and metal adhered from the workpiece. When laser welder welding thin metal lap joints, it does not contact the workpiece. In addition, the beam can also enter the areas difficult to be welded by conventional welding, and with fast the welding speed.
In addition, argon arc welding uses non consumable electrode and shielding gas, which is often used to weld thin workpieces, but the welding speed is very slow, and the heat input is much larger than that of laser welding equipment, so it is also easy to produce deformation.
In fact, compared with the traditional welding machine, the fiber laser welding machine also has limitations. Due to the high cost of its related systems, the equipment investment will be greater than the traditional welding equipment. In the welding process, it need assembly accuracy of the laser welder, and the position of the beam on the workpiece cannot be significantly offset.
However, compared with the traditional welding equipment, the biggest advantage of laser welder is non-contact welding, which is fast, efficient, simple and easy to operate. Therefore, laser welding equipment has gradually occupied the market. We know that laser welding technology is widely used in various industries, from automobile manufacturing, shipbuilding, aerospace, industrial electronics Precision machining replaces the defects of traditional welding in process application
Laser welding is a new type of welding method, which mainly aims at the welding of thin-walled materials and precision parts. It can realize spot welding, butt welding, overlap welding, seal welding, etc. it has high depth width ratio, small weld width, small heat affected zone, small deformation, fast welding speed, flat and beautiful weld, no treatment or simple treatment after welding, high weld quality, no pores, and can be accurately controlled, Small focusing light spot, high positioning accuracy and easy to realize automation.
At the same time, with the continuous upgrading and transformation of the laser welding machine, the precision of the laser welding machine is continuously improved. The refined processing method will make the laser welding technology play a more and more important role in the future micromachining field. Although the price of laser welding machine, laser marking machine and laser cutting machine are more expensive than traditional equipment, laser equipment has incomparable advantages in efficiency and technology, It is believed that in the future, laser welding technology will inject new power into our current processing together with other laser application technologies.
