And its own precision advantages will also be applied in more precision instrument manufacturing industries, thereby continuously benefiting the development of mankind and society. As a result, it itself is mainly used in high-tech fields, and in the future as people’s understanding and mastery of this technology continue to deepen, it will inevitably be applied to more industries and fields. So the factory should produce products with enough beauty and delicacy to improve competitiveness. In a certain range, as the flow of protective gas increases, the tendency to suppress the plasma increases, thus increasing the melt depth, but increases to a certain range that tends to smooth out. protection of the focusing lens from metal vapor contamination and sputtering of liquid molten droplets.
The reason for this difference is firstly due to the different degrees of ionization of the gas molecules and also due to the difference in the diffusion of the metal vapor caused by the different densities of the protective gases. Ionization energy 24.4615.6814.55.967.617.83As can be seen from the table, the plasma cloud size varies with the protective gas used, with helium being the smallest, followed by nitrogen, and the largest when argon is used. The presence of plasma as second energy on the working surface makes the depth of melt shallower and the weld pool surface wider. The second role of using a shielding gas is to protect the focusing lens from metal vapor contamination and sputtering of liquid molten droplets. The use of surface coating or surface generation of oxide film method to improve the absorption of the material to the beam is very effective. The absorption of the laser by the material depends on some important properties of the material, such as absorption rate, reflectivity, thermal conductivity, melting temperature, evaporation temperature, etc.

Developed for copper material processing in the electronics industry, these blue diode lasers are now available in six power levels between 300 and 2000 W. Polymer products can be laser-welded using a variety of process mechanisms and alternative equipment configurations such as gantry, robotic, scanner, or fixed diode arrays. The laser provides an efficient energy source to give precise heating and localized melting. The welds are completed rapidly, with high strength and good appearance. The advent of alternative absorbers for laser welding in 1998 allowed the joint to have much less visible color.
The introduction of arcs greatly improved the laser energy utilization rate, and the weld penetration ratio also increased by 5%-20%. There will be no dents after welding, and the amount of polishing and grinding after welding is reduced, saving production costs. In the welding of aluminum alloy, continuous laser has obvious advantages. Arc craters are prone to appear during argon arc welding, and laser welding is the same. Figure 2 shows the comparison of the welding seam of the battery shell after pulse laser welding and continuous laser welding. Embrittlement or even cracks occur when using traditional laser welding.
The purpose in developing the human-machine interface for its laser systems was the intuitive visualization and simplification of the laser welding process operation. Cailabs has introduced its CANUNDA-HP laser welding head for submillimeter ring beam shaping at powers up to 16 kW. laser was first used for this process, and welding of thin film is possible at very high speeds. Welding has been demonstrated with a range of plastic films at speeds of up to 1200 m/min.
Laser welding is a non-contact process that allows metal parts to be assembled mainly by means of a laser beam. Product designers and process engineers considering laser welding as an alternative to more conventional types of welding, such as MIG/TIG arc welding, will find each has its plusses and minuses. But for many applications laser welding is a cleaner, more precise, and more controlled method of welding and is especially much faster, cheaper and better controllable. A remote laser welding head, in combination with our robot controller, optimizes path configuration “on the fly”. The three-dimensional mobility of the laser beam increases utilization of the robot and minimizes the time between welds.
Our range of Fiber Lasers are “fit and forget” and are inherently zero maintenance with all of the traditional Laser components built into a fiber optic. This removes the requirement for re-alignment and makes it a truly industrial tool which can be operated with a minimum amount of fuss and hassle. DIVYA MEDIA PUBLICATIONS PVT. LTD is in the business of publishing magazines from last 20 years in the industry. Today it is recognized as one of the leading publishing company headquartered in the Mumbai, India.
Delivering a focused heat source, laser welding creates a strong seam at a high speed. Some of the laser welding machines utilize a 5- or 6-axis control and others utilize a fully articulated wrist. Generally for low thickness of metal like 0.5 to 0.6 mm, it is difficult to weld with traditional technology but with fiber laser welding system it can be done efficiently, cleanly and smoothly. Also aluminium to aluminium welding was a typical task with traditional technology but with this technology; one can do aluminium welding very easily. Because of increase in consumption of fiber source and price war among fiber laser source producers, the price of fiber laser source is coming down. As a result, the prices of fiber laser cutting machine, welding machine, and marking machine are also coming down and they have become truly affordable to anyone.
This standard configuration limits each setup to a specific application. In the field of tool manufacturing, the versatility of laser welding is the characteristic that comes into play. Laser welding is often brought in to join separate elements and achieve a tool’s intended form factor.
