The LWS2000 is a LASER welding machine with LASER cutting facilities. Two stainless steel flat sheets that make the heat exchanger are placed on top of each other on the table (right picture). The sheets are pulled into the welding area using the gripper clamps on both sides of the sheets (right picture). In the welding area (middle picture) the sheets are hydraulically clamped by the clamping bench to avoid deformations during the welding. The LASER welding head can weld in an area of 35 x 3000 mm. Once welded, the gripper clamps move the metal sheets 35 mm further. The laser welding is done using a shielding gas, resulting in a perfectly white coloured weld. Once the complete surface is welded a water inlet is manually welded on the heat exchanger. Subsequently water under high pressure is injected to inflate and create a tubed surface as shown in the picture below.
