WHy LaserCarb®:Numerous industries use tools that require very high resis-tance to abrasion. The Lasercarb process is a hardfacing pro-cess, that is, one that adds an anti-abrasion material to wear parts. The Lasercarb process resolves numerous problems related to welding. Lasercarb uses powders based on fused spherical Tungsten Carbide produced by Technogenia.

prImAry ApplICATIONs:All steels that are difficult to weld with an oxyacety-lene torch: stainless/non-magnetic steels used for oil-drilling tools.> Wear parts in the agri-food industry, > Paper industry, > Ceramics industry, > Foundries, > Tunnel boring, > Pump ring and shaft, > Cylinders and rollers in the steel industry, etc.
spECIfICATIONs:> Deposit thickness: 0.5 to 3 mm. Greater thicknesses:
contact us.> Capacities: X = 3000 mm, Y = 1000 mm,
Z = 400 mm,> Weight: 3000 kg (Saint-Jorioz site)> Possibility of hardfacing done internally.
Contact us.> Lasercarb coatings can be ground either directly in
our workshops or subcontracted out, depending on the shape.
> Due to their extreme hardness, Lasercarb deposits cannot be machined except for grinding with diamond tools.
TypEs Of COATINGs:The Lasercarb process preferentially implements Techno-lase® powders based on Sphérotène®: Spherical fused Tungsten Carbide by Technogénia.
OTHEr pOssIBlE TypEs Of pOWdErs:
Stellite powders, powders based on Inconel.
rECOmmENdEd TypEs Of BAsE mATErIAls:
All weldable steels and most stainless steels. The Lasercarb process is particularly well suited to non-magnetic steels used for, among other things, drilling equipment.> Titanium,> Certain types of (weldable) cast irons,> Tool steels.
ExAmplEs Of ApplICATIONs
prINCIplE:The process consists in using the energy of a Laser beam to melt the deposition powder (NiCr or other material) on the part. A weld occurs between the deposit and the base metal.
BENEfITs: Integrating the hardness and toughness of Spherotene (cast tungsten carbide spheres) produced by Technogenia and the unique properties of a high energy laser has produces a weld deposit without equal. The cast spheres exhibit hardness of 3000 +- 500 Hv, along with the ability to pack close together to produce a dense deposit. The spherical shape also increases toughness in the carbide grain and the overall deposit as well.
> Uses powders based on fused spherical Tungsten Carbide (Sphérotène),
> Very high hardness: 3000 HV ± 500,> Fused Tungsten Carbides are not affected by Lasercarb,> Nearly total absence of porosity,> Extremely limited cracking and deformation,> Large deposit thickness of 0.5 to 3mm (0.020 in to 0.125 in),> Perfect adherence through welding,> Precision, Automation, Reproducibility.
