Laser Fusion

Laser fused sections are produced by welding individual components to make one complete section. The parts are usually flat laser-cut strips, but may also be prefabricated solids, hollows or other shapes. The welds are made with powerful lasers without the use of filler material, producing very small weld seams. Virtually all commercially available steels can be welded and come with the appropriate approvals and certifications. The lasers can cut material up to 1-1/4” thick. Monolithic, homogeneous welds up to a depth of 3/4” are possible. This technology is used for the production of mild steel, stainless steel and duplex steel sections.

Laser fused sections generally feature small radii measuring max. .02" and therefore have sharp edges. They can be manufactured as tees, channels, beams and other sections. Hollow structurals are also available as well as square or rectangular tube. These can be made in almost any size with a small minimum order. The processed flat components can have different thicknesses and even different grades of materials fused into one section. The sections are manufactured on a large scale on several production lines, the selection depending on quantity, size and configuration. Laser fused items can be produced in quantities as small as one ton, as well as large projects of more than 1,000 tons per batch. The maximum production length is 40 feet, maximum width 40”and a maximum height of 80”. Small sections (1” X 1”) can be produced as well, with a minimum thickness of 1/8”. Most production consists of material welded at an angle of 90°., but it is possible to weld at other angles. Even round materials can be welded onto flat edges provided they can be joined perfectly tight. For such geometries it may be necessary to flatten the round material at the contact point.



Laser fused sections generally have a much better surface finish than hot-rolled or extruded products, as the raw material components are cut from high quality hot rolled plate or made from cold drawn flats. After welding, the sections are straightened and then sand blasted and passivated in an acid solution. This means impurities caused by the welding process are no longer visible on the material. Since box and angle sections generally have external welds, they are machined prior to sand blasting. With this operation welds are no longer visible, i.e. the surfaces are flat and even. The sections undergo a stringent quality control process, involving continuous checks with special measuring equipment. This measuring equipment is checked at regular intervals by TÜV (external approving authority) to verify its reliability. The sections are therefore supplied with appropriate certificates and approvals.

Load-bearing sections are also approved and are certified. Laser fused sections are used in many areas, including general building & construction, machinery, foodprocessing, pharmaceutical manufacturing, chemical process control, waste water systems and shipbuilding.
