The wire feeder design can be fed during the welding process automatically, which is suitable for industry and household use. The hand-held welding gun is more flexible and convenient, meets welding at various angles and positions. The welding seam is beautiful and firm, and the operation is simple, fast, flexible, and low in processing cost. Compared with traditional argon arc welding and TIG welding, the efficiency has a huge increase.
Carbon steel is a classic example of a metal that tends to become brittle and crack when cooled too quickly. Pulsing controls heat input, increasing quality of weld seams and preventing cracking. A variety of input and output signals are very easy to achieve the machine’s automated production and assembly line production. Excellent spectral system minimizes energy loss to ensure that the laser energy of each fiber is almost the same. It adopts a specific fiber to achieve the welding of tiny solder bumps.
Laser welding between different materials is only possible with certain combinations of materials. The connection of wire to lumped elements can be successfully achieved using laser welding, where the lumped elements can be of any size. The metal vapor absorbs the laser beam and ionizes into an equal plasma, and if too much plasma is present, the laser beam will be consumed by the plasma to some extent.
The portable handheld laser welding machine will take over the traditional argon arc welding and electric welding technology. Laser welding is often the ideal solution for joining metals that require relatively fast processing speed, low heat input, low heat affected zone and minimal distortion. The good beam quality of kW class fiber lasers coupled with medium to high average powers offer a wide range of laser welding mechanisms from narrow high aspect ratio keyhole welding to shallow wide conduction welding. Low to medium power CW fiber lasers are used for welding a very wide range of thin sheet materials up to 1.5 mm thick at very high speed.
Welding is usually used to focus the laser, generally choose 63~254mm (2.5″~10″) focal length of the lens. The flow rate should also be controlled, otherwise the laminar flow of shielding gas becomes turbulent and the atmosphere becomes involved in the molten pool, eventually forming porosity. The protective gas is injected through the nozzle at a certain pressure to the surface of the workpiece. It is not easy to cause porosity because of the light mass and can escape.
The parameters are adjusted by the lever in the sealed cavity, which is simple and highly efficient. Fast, efficient, deep, little distortion, little heat-affect area quality welding, welding points free from pollution, saves energy. You are provided with the laser, focusing optics with sensor system, and laser machine all from a single source and perfectly adapted to your specific application.
Laser welders are capable of delivering a precise pulse of light with accurate, repeatable power, energy and duration. When the laser pulse is focused into one place – a small spot – (adjustable anywhere from approximately 0.02 to 1.0 mm (0.001”-0.040”) in diameter) on the part, the power density is sufficient to cause rapid melting to create the weld. The high power density enables efficient absorption of the laser by creating the “keyhole effect.” As the pulse ends, the liquified metal resolidifies and creates a small spot weld.
In contrast, the Pulsed Fiber lasers deliver a pulse of energy which is typically ten to twenty times higher than their average power. For example, a laser can have 300 W average power and 6000 W peak power. These lasers are often referred to as Quasi Continuous Wave Fiber Lasers. Depending on the intensity of the laser radiation, laser welding is categorized as heat conduction welding or deep welding. How the model is built determines how much and on what you’ll be able to use it. You can choose from small and compact machines to very large laser welders with a bulkier build.
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.
Compared to TIG welding, pulsed laser-welding technology is said to enable faster overall mold repair time while maintaining higher metal hardness. If you would like to integrate a plastic welding machine into your round the clock production line, we will advise you the best machine for your purposes. See below for fact sheets and specifications and please feel free to contact our sales team for more information. The modular architecture of EBES’s Beamer Series addresses various customer requirements.
By controlling the width, energy, peak power and repetition of laser pulse Frequency and other parameters, the workpiece melting, forming a specific pool. Because of jewelry laser welding machine’s unique advantages, has been successfully applied to gold and silver jewelry processing and micro, small parts welding. It’s more flexible to implement flexible transmission of non-contact welding for those difficult to weld site.
The only danger to people present during this procedure is to accidentally look into the laser beam. For this purpose, special protective goggles were developed that absorb, attenuate and disperse the incoming laser light. Provided all people present pay attention to their personal protective equipment, laser beam welding is a particularly safe process. The processes and applications of laser welding are most prominent in the automotive industry, where lasers boost productivity at a low cost when welding automotive parts – such as roof , door or filter assemblies – together. Our Fiber Lasers for welding are supplied as complete units in 19” rack configurations. The carbon footprint is significantly smaller than traditional welding equipment which allows the Laser to be placed close to the application or to use the advantages that fiber delivery can give.
Above all, the use of laser welding for metal parts improves productivity by reducing the time spent on welding and straightening the welded parts and allows greater freedom in the designing of parts . Laser welding also helps make savings by reducing production costs and the materials consumed by the welding process. This welding method also affects the quality of the assembly by offering mechanical strength that is at least equal to that of the base material, and by reducing the part deformation rate.
