Laser surface modifications at Tata Steel

In the manufacture of steel strip work, components have to perform in exceptionally aggressive environments and withstand service at high temperatures in corrosive atmospheres under mechanical wear and frequent and heavy impact loading. Conventionally, components that are subject to high wear or corrosion have often been manufactured from rich chemistry steels or hardfaced using submerged arc clad martensitic stainless steels (MSSs) to increase their service life and therefore maximize line throughput by extending maintenance intervals without any sacrifice to product quality.

Laser surface modifications in steel industry

Components used in the manufacture of steel strip work in exceptionally aggressive environments and have to withstand service at high temperatures in corrosive atmospheres under mechanical wear and frequent and heavy impact loading. Conventionally, components that are subject to high wear or corrosion have often been manufactured from rich chemistry steels or hardfaced using submerged arc clad martensitic stainless steels to increase their campaign life and therefore maximise line throughput by extending maintenance intervals without any sacrifice to product quality.

Weld spot in the limelight

The camera of Precitec’s coaxial LPF seam tracking system directly observes carroof seams through the welding optics. In the example described here, two line generators positioned on top of one another create two light stripes that run perpendicular to the weld about 3 to 5 mm in front of and behind the weld spot.

Intelligent high-power welding head

For the challenging task of welding variable joint positions, the tools of choice are intelligent welding heads, which measure the position of the joint in order to place the weld seam at the correct position.

Smart laser welding heads provide excellent quality

concerted functionality enables high productivity and efficiency

Equipped with pulsed Nd:YAG lasers, single-mode fibre lasers and “conventional” CO2 lasers, the BBW Lasertechnik GmbH in Prutting, Upper Bavaria, tackles cutting, drilling, inscribing and welding tasks. BBW mainly processes sophisticated small components in stainless steel, spring band steel, steel and aluminium.
