With the continuous advancement of science and technology and the rapid development of industrial manufacturing, welding technology, as an important connection process, plays a vital role in various industries.
In the laser welding process, wire feeding is a common auxiliary technology that can improve welding quality and efficiency. Laser welding is suitable for self-fusion welding. Usually, no welding material is added and the joint is formed by melting the welding material itself. However, to reduce the assembly accuracy, improve the weld formation and improve the adaptability of the welded structure, the filler metal is also required. Filler metal is usually added in the form of welding wire, which can be cold or hot. During deep penetration welding, the amount of filler metal should not be too large, so as not to damage the small hole effect.
Laser welding machine wire feeding advantages
1.Laser welding machine wire is beneficial to the welding of brittle materials and dissimilar metals. For example, laser welding of dissimilar steels or steel to cast iron may cause weld cracks due to differences in carbon and alloying elements. The filler wire can adjust the metal composition of the weld, reduce the carbon content, increase the nickel content, and inhibit the formation of brittle structures. Laser multi-layer wire welding can also use lower-power laser welding equipment to realize the welding of large-thickness plates and improve the adaptability of laser welding to thick plates.
2.Multi-material composite welding can be realized by using wire-feeding technology in the laser welding machine process. By simultaneously feeding wires of different materials, composite materials can be formed in welded joints to meet specific engineering requirements.
3.The wire feeding technology can control the wire feeding speed of the welding wire, which matches the laser welding machine speed, and realizes the uniform and continuous formation of the welding seam. This method can increase welding speed and improve production efficiency.
4.Laser welding machine and wire feeding technology can be combined with automation systems and robot technology to realize a highly automated welding process. Through the precise control and intelligent algorithm of laser welding and wire feeding process, automatic tracking and real-time monitoring of complex welding paths can be realized to improve production efficiency and product quality.
