The advantages of laser welding machine in thin metal production

Laser welding is one of the most important part in laser processing. With high energy laser beam as a heat source, laser welding is a high precision welding technique. It uses high energy laser beam to heat up the surface of the work piece and then the heat will spread from the material surface to the inside. With the parameters of the laser pulse parameters being adjusted, the laser beam energy will melt the materials and then molten bath will form.

Laser welding machine can combine materials of different types, different thickness and different shapes through the laser energy so that the finished work piece can get the best performance from each part.

So what is the advantage of laser welding machine in thin metal production?

Stainless steel has a wide application in different industries. And thin stainless steel welding has become an important procedure in metal production, but the unique feature of thin stainless steel makes it hard to perform welding on it. So the thin stainless steel welding used to be a great challenge.

As we know, thin stainless steel has very small heat conductivity coefficient which is only 1/3 of the normal low carbon steel. Therefore, once some of its parts receive heating and cooling during the welding process, it will form uneven stress and strain. The vertical contraction of the weld line will form certain amount of stress on the edge of the thin stainless steel. The drawback of using traditional welding machine on thin stainless steel is more than than this. Burning and deformation are also real headaches for the metal fabricators.

But now, the advent of laser welding machine perfectly solves this challenge. Laser welding machine features small weld line width, small heat affecting zone, little deformation, high welding speed, beautiful weld line, ease of automation, no bubble and no requirement of complicated post-processing. With all these advantages, laser welding machine is gradually replacing traditional welding machine.

Most of laser welding machines used in the thin metal production are powered by fiber laser from 500W to 2000W. Fiber lasers of this range are easy to generate lots of heat. If those heat can not be dissipated in time, it will cause critical damage to the fiber laser and shorten its lifespan. With industrial water chiller unit, the overheating is not a problem any more. S&A Teyu CWFL series industrial water chiller unit is the perfect cooling solution for the fiber laser ranging from 500W to 20000W. The CWFL series industrial water chiller units share one thing in common - they all have two independent cooling circuits. One is for cooling the fiber laser and the other is for cooling the laser head. This kind of design not only improves the refrigeration efficiency but also saves space for the users, as now only ONE chiller can finish the cooling job of two. Besides, the temperature control range is from 5-35 degree C, which is sufficient enough to provide efficient cooling for the fiber laser welding machines.
