Heavy-wall tube cutting is one of the most demanding applications for tube laser cutting machines, requiring high laser power, advanced cutting parameters, and robust machine construction. Tubes with wall thicknesses of 12mm to 50mm are used in applications such as pressure vessels, offshore platforms, heavy equipment frames, and pipeline construction, where structural integrity and weld quality are critical. Traditional cutting methods for heavy-wall tubes—oxy-fuel torches and plasma cutters—produce wide kerfs, large heat-affected zones, and rough edges that require extensive grinding before welding, adding significant labor costs and reducing productivity. A high-power fiber laser cutting machine cuts heavy-wall tubes with a kerf width of just 0.2mm to 0.4mm, a heat-affected zone of less than 0.5mm, and a clean, square edge that is ready for welding with minimal preparation. RAYMAX’s high-power tube laser cutting machines are available with laser sources from 6000W to 12000W, capable of cutting carbon steel tubes up to 50mm wall thickness and stainless steel tubes up to 40mm wall thickness in a single pass. The machine’s heavy-duty L-shaped bed structure provides the rigidity needed to maintain cutting accuracy under the high dynamic loads associated with thick-wall cutting. For a heavy equipment manufacturer processing 25mm wall thickness carbon steel tubes for excavator boom arms, RAYMAX’s 6000W tube laser cutting machine reduced cutting time from 45 minutes per tube (using oxy-fuel) to 4 minutes, with edge quality that eliminated grinding before welding. The machine’s bevel cutting capability (optional) allows operators to create V-grooves and other weld preparations directly on the heavy-wall tube end, further reducing downstream processing. The three-chuck design provides stable support for heavy tubes weighing up to 2000kg, ensuring that the tube does not deflect during cutting, which would affect accuracy. For oil and gas pipeline applications, the ability to cut bevels on heavy-wall pipe ends with a tolerance of ±0.5° ensures consistent fit-up for field welding, reducing installation time and improving joint integrity. The machine’s enclosed design with fume extraction protects operators from the heavy smoke and particulate generated during thick-wall cutting.
