Diode Lasers for Cladding & Coating

Supplier: Raymax Lasers playlist_addCompare

Coating processes are used for a multitude of metal components that are subject to corrosion or wear. Using state- of-the-art fiber-coupled diode lasers, they become particularly stable and are easily automated

In cladding, hard particles or metal powders are injected into the laser beam and fused with the base material. In one single operation, the substrate is coated, alloyed or locally reworked. This yields high precision and excellent reproducibility in cladding and coating - a guarantee of quality.


The range of applications of diode lasers in cladding and coating is very large. Diode lasers are used in corrosion and wear protection in the automotive industry (such as valve seats), in wear protection for tools in offshore oil drilling, for hydraulic cylinders in mining, and for reworking expensive tools.

Diode lasers - wherever it is important to maintain value.

  • Coating with low heat input
  • Homogeneous microstructure of sound adhesion
  • High process stability
  • Robust, easily automated process
  • High reliability in production
  • Highest process efficiency of all laser types

In many industrial fields, diode lasers stand for cutting edge technology. In cladding and coating they are also considered proven and well established. Their intriguing profitability is based on the extremely high efficiency of the laser and the high processing speed.

Furthermore diode lasers are virtually maintenance free, even in very dusty environments of coating applications.

Fiber-coupled diode lasers in the power range between 2,000 W and 8,000 W are used for cladding and coating applications. They are usually equipped with dust protection and use standard cladding heads.

Their flexibility and high reliability in production result in further cost advantages for the user.

There are many different ways of surface treatment to protect against corrosion and wear, but diode lasers provide an increasingly popular solution. The range of possible applications is huge and the technology has proven itself to be very innovative.

In comparison with conventional technologies, the advantages of diode lasers can be summed up in two words:

Better quality.

Traditional processes in cladding and coating often lead to high heat input with the consequence of component distortion, formation of coarse grain structure and an inferior adhesion to the base material. The diode laser, however, stands for low heat input and consistently high quality.


The advantage of diode lasers over other laser technologies can also be summarized in one resounding argument unrivaled in their cost effectiveness and extremely robust. Therefore, complex coating applications will always return to this equation:

quality + profitability = diode laser
