The German glass machinery manufacturer GlamacoCoswig has developed a new technology for laser welding of flat glass in cooperation with IFW Joining Technology and Materials Experimental Institute. The extremely high cooling rate and the small heat-affected zone of laser welding create favorable conditions for the compatibility of materials with different structures after welding and melting of many different metals. From the foreign situation, the laser beam quality and output power stability has been quite high, will not become a problem for laser welding. Currently, China’s lasers are still difficult to use for laser welding in terms of beam quality and power output stability. The laser welding process often uses inert gases to protect the melt pool, and for most applications helium, argon and nitrogen are often used for protection. Due to the small focused spot of laser welding, the equipment accuracy of the workpiece joint is required to be high, and a small equipment deviation can produce a large processing error.
In order to manufacture metallic objects by means of 3D printing technology, the only option left until a few years ago was to use these materials for the production of casting cores. However, metal-powder laser welding now makes it possible to manufacture products of any shape by means of 3D printing. This discovery is currently providing laser welding with another boost.
Fiber laser system manufacturers, thus, have developed new hardware that makes new product applications possible. Each of these welding processes have multiple practical uses within the manufacturing industry. In the hands of the right professional, the technology can help create customized pieces for various applications. Thus, heat conduction welding is used mostly to join parts with thin walls. The laser produces a smooth, rounded seam that does not require any extra grinding or finishing.
It should be noted that the upper layer can be colored and even opaque using special non-absorbing colorants. Application of the system can fully or partially replace arc welding, resistance welding and other traditional welding processes. The industrial blue laser manufacturer has appointed technology industry veteran Guy Gilliland, Ph.D., as CEO alongside photonics executive Chris Baldwin as CFO. Semicrystalline types are a mixture of small crystallites surrounded by amorphous material.
This precision decreases machining and rework time because there is less weld to remove. Another limitation of lasers early on was that they were a stationary pieces of equipment with relatively limited physical reach. That made laser welding impractical in many cases, particularly with large molds. This may not be visible from the top of the finished weld, but it will be revealed once the area is machined. Molds repaired with laser and TIG welding may look the same to the naked eye. However, once you put those molds to the test of a repetitive injection molding process at 20,000 psi, the results will be very different over time.
After all, these classic welding techniques are still the most commonly practiced and are likely the entities that laser welding will be put up against. Quick, reliable solutions for welding bumpers, tail light assemblies, dashboards and many more applications. The GLX is Branson’s premier, global laser welder offering high speed, high volume welding of medium and large parts. The GLX allows designers to incorporate barely visible, particulate -free weld lines into large designs. Laser Welding is a joining solution that creates a particulate-free, clean joint. Laser welding is capable of joining together a wide range of materials.
When it comes to the automobile industry, speed and quality are probably the two most important factors to consider. The tool-free operation of lasers welders means that there is reduced downtime for regular maintenance and tool changes. Laser welding machines are typically fully automated and have enclosed working spaces. This means that personnel no longer need to be exposed to the high temperature and particulates generated during welding. Even on this merit alone, a laser welding machine is already a worthwhile investment.
