Laser cladding enhances high wear component lifecycle and reliability

There are numerous different heavy vehicles and machinery components where the laser cladding process can be used to mitigate the environmental and operational impact on their performance, in turn enhancing their life-cycle and reliability. Excavator buckets, track components, mechanical crusher components, engine and drive train parts and conveying

Andy Toms explains: "The laser makes it possible to quickly and efficiently coat even large surface areas with powder deposit welding on the often high value components within these sectors that require repair or reconditioning. Unlike some alternative technologies, the localised and controlled heat affected zone produced by the laser does not impact the mechanical properties of the surrounding material. This also ensures that component distortion is avoided. In addition, the repeatability and precision of the process guarantees consistent quality on each and every part."

The laser cladding technology available from Bromsgrove based TLM Laser is ALPHA LASER’s AL-TW, AL-FLAK and AL-ROCK laser systems. These systems use Fiber Lasers to deliver the high power (450 / 900 watts) required for laser powder deposition welding.

ALPHA LASER’s systems’ which have already established an enviable reputation for laser welding, can also be used as powder coating / cladding systems. The AL-TW is an open system that provides the highest levels of flexibility within a workshop environment. The high levels of stability inherent within the system allows the precision focusing required to achieve the best results at all times. The AL-FLAK is an extremely robust laser welding system with a high laser power and large reach. The innovative movement mechanism and the projecting laser arm make it possible to work easily on large components, either manually or in programmed mode. 

The AL-ROCK also boasts high laser power and large reach. The combination of the ability to move the system under its own power, the articulated robot arm, plus the systems 3D scanning head make it possible to easily work on large components, performing either deposit welding or hardening processes in three dimensions. The area to be processed can be easily programmed, using the scanner software, by simply selecting the area that you wish to scan. The robot then moves the scanner automatically to the marked area over multiple tracks. The result is a real-time 3D model. The operator then simply configures the process-relevant parameters, after which the program is simulated virtually.

These highly flexible, powerful and precise laser systems are available from Bromsgrove based TLM Laser, ALPHA LASER’s UK and Ireland distributors, and just part of the comprehensive range of laser based technologies and systems offered by the company.
