The highly focused laser can thus provide welding, cutting and heat treatment functions. AWING entry level metal sheet laser cutting system, widely used in lighting, kitchen ware,cabinets,elevator etc industry. Laser Cladding, also known as Laser Metal Deposition is used to enhance, restore and strengthen the surfaces of metal components with unprecedented quality, reliability, wearability, and precision. Laser Cladding has a wide array of applications, and we believe the industry has yet to open the vast opportunities it presents. that deforms thin materials, produces poor visual finishes, is difficult when welding copper and limited welding metals of dissimilar thicknesses.
In comparison, the Neutec® PulsePoint™ Plus 140 packs a power output of 140 joules, which will allow you to work on even the hardest materials. AMADA WELD TECH is unique in that we not only manufacture the laser welders but also engineer and integrate laser systems, offering designers a one-stop shop for laser processing systems. This includes running samples of the process in-house to ensure it does the entire job as specified, and answering in-depth application questions. Learn the basics of laser welding and how manufacturers are using fiber lasers to solve common welding challenges. This webinar is ideal for those new to laser welding as well as anyone looking for a refresher course. For now, the fiber handheld laser welder is the advanced technology which is the best type for welding aluminum, it’s supper fast and eco-friendly but easy to operate.
The laser also enables operators to add additional alloy to jewelry pieces where needed. “Filler materials” of similar alloys, such as platinum, can be welded to castings, a technique commonly used to fill porosity holes. Filler materials are also used to increase the support structure of a complex assembly, mount settings to shanks, or resize rings. Laser is a acronym for “Light Amplification by the Stimulated Emission of Radiation.” This technology produces a sharply focused light beam that melts a very small area of metal and can be used to join similar or dissimilar alloys.
Widely used in manufacturing, this was the first welding method to use lasers. The process requires a transparent upper plastic layer and an absorbing lower layer. As the beam passes through the upper layer to heat the lower layer, the lower plastic reaches its melting temperature—passing heat to the transparent upper layer. The weld occurs at the interface when both plastics reach their melting stage. In transmissive welding, both plastics must have similar melting ranges. After setup, a high voltage power supply is applied to the laser machine.
When combined with robots, lap or seam welds can be made over a complete auto body. Other examples also include hermetic welding of battery packs and pressure seals. Material, component design and bond stress are a few factors that determine the joining method. The consistently high precision of laser welding is its outstanding feature. In addition to the particularly fine seam, the low temperature input is the most important plus. In contrast to gas-shielded welding, where work is slow and a lot of heat is applied, laser welding is extremely fast and minimally invasive.
With additive manufacturing, components are generated layer by layer using powder and laser light on the basis of a 3D model. Any explicit consent from you to process your personal data can be revoked at any time by unchecking the following checkbox.

Wobble welding oscillates the beam back-and-forth at various frequencies to produces wider seams, more aesthetic welds and for parts with poor fit-up. LightWELD comes with optimized, preprogrammed wobble parameters and allows on-the-fly control of up to 5 mm of wobble welding at adjustable frequencies up to 300 Hz. For stainless steel, galvanized steel, mild steel and aluminum, you can weld single-sided up to 4 mm and up to 10 mm double sided – copper single-sided up to 1 mm and double-sided up to 2 mm.
The low distortion of localized heating by laser welding also makes it easier to make high-precision parts with accurate dimensions. In many ways, laser welding fits right in with just about any application of standard, old-fashioned welding. Given how long welding has already been established as a manufacturing process, applications of laser welding aren’t exactly hard to identify. Localized delivery of power through the lasers means that joints are welded together pretty quickly. However, it also means that the heat in the joints is dissipated through the material just as rapidly.
The two-beam parallel and serial welding modes and welding at different welding speeds were studied. For high-reflective materials such as aluminum alloy, laser hybrid welding can preheat or melt the surface of the material by arc energy, which greatly improves the absorption of laser energy by aluminum alloy. Aiming at the stability of the aluminum alloy laser welding process and the quality of the weld. Once the “small hole” in the workpiece is formed, when the deep penetration welding starts, the absorption rate of the liquid metal to the laser increases rapidly after the metal is melted.
The laser beam can realize the spectrum separation on time and energy, it can do multi-beam processing at the same time, it provides the conditions for high precise welding. OREE laser hand-held fiber laser welding machine adopts the latest generation of fiber laser and is equipped with intelligent laser welding head. It has many advantages such as simple operation, beautiful welding line, fast welding speed and no consumables.
Laser hybrid welding increases the geometric size of the molten pool through the coupling of the laser beam and the arc, and changes the flow conditions of the material in the molten state, which is beneficial to the elimination of pores. In addition, in laser welding of aluminum alloy, the faster the welding speed, the more likely it is to crack. In the aluminum alloy welding process, some low-boiling elements (Mg, Zn, Mn, Si, etc.) are easy to evaporate and burn. The slower the welding speed, the more serious the burning, which changes the chemical composition of the weld metal. For highly reflective materials, such as aluminum alloys and copper alloys, it is necessary to provide a very large power density during welding. Based on some characteristics of the aluminum alloy itself, the laser welding process is more complicated, and it is urgent to improve and perfect.
For CW fiber lasers the power and spot size, and position of focus are key parameters. With each of the lasers these parameters are precisely controlled to provide the exact weld needed, whether for mechanical strength or a level of hermetic sealing. By virtue of the camera and the welding spot identification system of the handheld laser welding machine, the conditions of insufficient welding and omitted welding can be avoided effectively and therefore, the welding quality is guaranteed. Main parts uses imported accessories to ensure that the equipment works stably for a long time.
