Overview This 400 W pulsed YAG laser welder adds a 4-axis ball-screw table with a rotating worktable to the standard 2-axis platform. The rotary axis lets the machine weld cylindrical parts — shafts, sleeves, bushings and round mold inserts — without refixturing, while the linear axes cover flat sealing seams up to the full table stroke. With 150 J maximum pulse energy, 0.1–3.5 mm welding depth and a 0.3–1.2 mm spot, the system handles both micro build-up work on tool steel
