Applications
The main fields of application are to be found in machine-tool and plant engineering, and engine manufacturing for the aircraft and automotive industries. Laser cladding can be used for a wide variety of purposes.
Process
Laser cladding is a deposition welding process in which a layer of powder is deposited on the substrate material, and the two materials are fused by metallurgical bonding through the action of a laser beam. The characteristic features of this process are:
- highly precise, automated deposition of a layer of material with a thickness varying between 0.1 millimeters and several centimeters
- Metallurgical bonding of the cladding material with the base material
- Low heat input into the substrate
- A wide selection of homologous and non-homologous powder materials
- The ability to process virtually any type of metal alloy By varying the process parameters and selecting different powder materials, a component’s surface can be either alloyed or cladded with a carbide or similar coating. Typical deposition rates lie in the region of several cm2 per minute for layers with a thickness of around 1 mm.

Clients
From welding of special gears for small batches of gearboxes, to rack-and-pinion steering gear, differentials, cylinder blocks, suspension arm strengthening ribs and advanced devices at the cutting edge of racing technology, you can depend on us to keep your team in pole position. We weld aluminum alloys, steel and titanium and resolve your high-tech welding issues. Prototype work is frequently undertaken.
Standard motors have straight plain output shafts, and need gears or actuators welding on. Laser welding is ideal for its accuracy in aligning the gear and welding it firmly in place, and the low heat input avoids damaging the motor. Cars weld front wing trim actuators and gear selector motors for various teams.
The laser spot welding is an important aspect of laser process technology application. The spot welding process is thermal conduction, i.e. the laser radiation heats the surface of work piece, and the surface heat diffuses to the interior through thermal conduction and melts the work piece by controlling the width, energy, peak power and repeating frequency of laser pulse to form specific molten pool. Because of its unique advantage, it is widely used in the process of gold and silver jewelry and welding of mini and small parts.
Pulse laser welders are electronically compatible and ideal for voltage sensitive applications. Precision automated or manual welding construction can be performed on electronic/industrial components with a high degree of accuracy, while eliminating the potential hazards of heat damage or thermal stress to complex manufacturing materials.
For flat plate solar energy collectors, the aluminium sheet and copper tube is thin, traditional welding will cause irregularity in welding depth, blemish, and destroying the covering film of the collector.
Laser Hybrid welding is a type of welding process that combines the principles of laser beam welding and arc welding. The combination of laser light and an electrical arc into an amalgamated welding process has existed since the 1970s, but has only recently been used in industrial applications.
We manufacture & supply an excellent assortment of our Glove Box Welding Machines, which is widely accepted by our clients all across the globe. Our such range is fabricated from high grade material that makes it more reliable and durable. These machines are very efficient as they are built using advanced technology.
The Pillow Plate (or thermo plate) consists of two steel plates, connected by laser welding. After being welded together, the plate is inflated by using water pressure. The water pressure creates a specific single or double embossed profile – the pillow plate, through which the cooling or heating medium is conducted. While the thickness and the spot pattern is determined by the design pressure.
Tailored blanks are semi-finished parts, which are typically made from sheets with different alloys, thicknesses, coatings or material properties. After joining, these will be subjected to deep drawing or stamping.
It incorporates space saving design and ease of use. Its high cutting speed and very low operating cost makes the most affordable system on the market. The Lasersystem can cut both framed and frameless stencils, without requiring any changeover. The light weight motion system allows excellent positioning accuracy while maintaining cutting speeds that are the highest in its class.
