Fiber laser welding machine of Raycus laser source Vicky

Compared with traditional welding methods, laser welding machine has significant advantages-low heat input, fast welding speed, small heat affected zone, and small thermal deformation. In recent years, laser welding machine has been widely used in the automotive industry. Shipbuilding industry. Nuclear power industry, aerospace industry, and other high-tech industries are becoming more and more widely used. And with the reduction of the cost of complete equipment. Applications in daily hardware and other life-related fields have begun to grow rapidly.

In order to meet the development needs of various industries. The methods have also been improved. Laser wire filler welding, due to its concentrated welding energy and small deformation. It can reduce the gap margin during butt welding, reduce welding defects. And become an effective alternative to traditional arc welding in rail transportation and the automotive industry.

The laser not only needs welding wire. But also needs to melt the base metal and form a small hole effect peculiar to laser deep fusion welding on the base material to form a deeper molten pool. The welding wire component fully mixed to form a new mixed molten pool. The element composition of the mixed molten pool, its proportion, and quality are relatively different from those of the welding wire and the base metal. Therefore, according to the performance defects of the base metal itself. The suitable welding wire can add to the welding process. So as to be on a micro level Purposefully improve the crack resistance, fatigue resistance, corrosion resistance, wear-resistance and other aspects of the weld.

With the development of laser filler wire welding technology and the increase of the upper limit of laser power, the application scope of laser filler wire welding is becoming more and more extensive:


Application fields of laser filler wire welding

1 laser filler wire welding aluminum alloy

2 laser filler wire welding dissimilar metals

3Improve weld formation

4 Narrow Gap Filler Welding

Among them, for the two applications of improved weld formation and narrow gap filler wire welding, we use actual application cases to see the effect of laser filler wire welding.
