China Portable laser cladding welding machine Manufacturer, Supplier

Laser cladding is the technology of high-eneregy laser beam (104-106w/cm2) radiation on the metal surface meanwhile additive alloy powder to form a new layer of low dilution rate to make up the shortage of the base material, of which the process of melting, spreading and solidifying swiftly to cladding a layer of material with a special features on the base. It would be cladding the metal and nonmetals as the needs, such as the heat resistance, wear resistance, corrosion resistance, oxidation resistance, fatigue resistance or optical, electrical and magnetic properties. It is the technology of high efficiency that it would make the eminent properties layer on the base of affordable material. That would save the cost.

Product Description

Rapid Cooling & Solidification

Cooling swiftly, up to 10⁶ ℃/s. Solidifying swiftly, it is easy to get the fine grains microstructure or the cenotype which cannot form under equilibrium producing conditions.

Controllable Metallurgical Bonding

It is possible to control the focus distance and penetration to adjust the dilution rate, due to the metallurgical bonding between the welding material and the base.

Minimal Heat Impact

Low heat impact and tiny deformation, only melting on the surface in the course of cladding (0.1-0.5mm).

High Density Cladding Layer

High density of the cladding layer. There is not any shortage of holes, slag, and cracks, with hardness reaching 18-60HRC.

Flexible Material Choice

Barely any limitation in choosing the powder, even allowing high melting point material cladding on low melting point ones.

Remote & On-Site Repair

Proper for remote transmission and suitable for repairing huge parts directly on-site.

Deep Hole & Groove Access

It is possible to clad in the place of grooves, deep holes, etc., because there is no need for physical contact during laser cladding.

Hand-Held System Operation

Works exceptionally well using hand-held laser cladding systems for parts with complex shapes, without the trouble of programming.

Frequently Asked Questions (FAQ)

What are the microstructural benefits of rapid cooling in laser cladding?

With swift cooling rates up to 10⁶ ℃/s, the solidification process happens rapidly. This makes it easy to obtain a fine grain microstructure or a cenotype structure that cannot be formed under balanced producing conditions.

How does laser cladding ensure strong bonding between materials?

Laser cladding creates a reliable metallurgical bonding between the welding material and the base. This process allows operators to control the focus distance and penetration depth to achieve the desired dilution rate.

Does laser cladding cause significant heat damage or deformation?

No. Laser cladding results in low heat impact and tiny deformation. The melting is localized, occurring only on the surface layer (0.1–0.5 mm) in the course of cladding.

What is the density and hardness achieved by the cladding layer?

The cladding layer features a very high density, and is free of defects such as holes, slag, or cracks. The hardness achieved ranges from 18 to 60 HRC.

Can laser cladding be used on complex shapes or remote areas?

Yes, because it is a non-contact process, it is possible to clad in tight spaces like grooves and deep holes. Additionally, hand-held laser cladding systems can repair complex shapes on-site, and it is proper for remote transmission applications.
