Laser welding can achieve exceptionally high strength due to its deep seam and full connection of sheets. Despite their narrow appearance, laser-welded seams are incredibly stable. Unlike traditional methods, where seam width is crucial, laser welding excels through complete seam penetration. Our tests show that tube connections in heat exchangers have withstood pressures of up to 548 bars. Interested in testing your parts? We can perform welding trials and evaluate the results together.
