Laser marking machine, laser engraving machine laser welding technology is an important part of the laser industry, today we look at the robot and stainless steel laser welding machine the perfect combination:
Laser welding is the most rapid development of laser processing technology. Laser welding is a high-intensity laser beam radiation to the metal surface, through the interaction of laser and metal, metal absorption into heat to melt the metal after cooling crystallization of the formation of welding. Compared with the traditional welding methods (such as Table 2), robot YAG laser welding technology will bring many advantages:
A can realize the power and size of the laser focus dynamically adjusted according to processing requirements, while real-time monitoring of the processing process to achieve a wide range of applications may be.
B beam spots, processing accuracy doubled. Heat affected zone is very small, high quality weld, not easy to produce shrinkage, deformation, embrittlement and thermal cracking and other hot side effects, laser welding pool cleaning effect, to clean the weld metal, weld mechanical properties equivalent to or better than base metal .
C A stainless steel laser welding robot can replace 3 to 4 resistance welding robots. If you make full use of laser welding technology to process a body, the cost of tooling investment, welding preparation, material consumption and body sealing will be reduced by about 200%. US dollar, steel utilization can be increased by 50%. The use of stainless steel laser welding machine can save a lot of templates and tooling equipment, so that the workshop area by half, saving investment.
D uses optical fiber to transport the laser, so that it is not difficult to separate the energy source and the processing equipment from the space. Laser light can be transmitted through a very small diameter fiber to a far distance from the station, through the robot, to achieve the welding of the workpiece.
Stainless steel laser welding machine in the automotive industry, as a key component of the car body, the value of about 20% of the entire vehicle, the use of laser welding, can reduce the overlap width and some strengthening components, can also compress the body structure itself , Only the weight of a body can be reduced by 56kg. Similarly, for a large number of spot welding in body assembly, if a welding head is clamped on the edge of the workpiece for welding, the width of the flange needs to be 16 mm, while the laser welding is unilateral welding, only 5 mm, Welding, each car can save 40kg of steel. Welding with conventional 0.8mm steel plate stamping two pieces, an average of 20 points / min, welding torch is 25mm, the speed of 0.5m / min, with laser welding speed can reach more than 5m / min.
