Basic equipment: RFL-C6000 laser, welding head, welding machine, wire feeder, hard shot
Welding platform: robot
Wire feed speed
5mm aluminum alloy butt joint
6mm aluminum alloy butt joint
Both application solutions were installed in our terminal customers (a rail transit equipment manufacturing company in Qingdao). One of the products produced was the locomotive parts, as shown in the figure below, and achieved good welding results.
Comparing the two options
the scope of application is different
For materials with the same thickness of welding, Laser Welding with Filler Wire requires higher laser power, but higher welding efficiency can be obtained, and it has a greater advantage in welding thinner plates. For the RFL-C6000 laser, the recommended thickness of the aluminum alloy is 1 to 4 mm.
Laser-arc Hybrid Welding can achieve the same weld penetration with lower laser power because of the arc heat into the welding process. However, to ensure the formation of the weld, the welding speed cannot be too fast, and the equipment cost will increase, but the Laser-arc Hybrid welding can complete the welding of the thick aluminum alloy. For the RFL-C6000 laser, the recommended thickness of the aluminum alloy is 4 to 7 mm.
Compared with traditional arc welding and resistance welding, laser welding has the advantages of fast welding speed, high production efficiency, narrow weld and heat affected zone, and small welding deformation. Therefore, research on the laser welding technology of stainless steel body in the field of rail transportation has received increasingly attention.
We will use laser welding to solve the problem for the manufacturing of key components of rail transit. We also expect that laser technology will be used to help the rapid development of China's rail transit and the entire manufacturing industry in the future.
