Sigma Laser Systems is pitching precise, low-heat welding for crack-prone tool steel molds.
The systems combine 5-axis motion, Nd:YAG or Ytterbium fiber sources, Super Pulse Technology and Leica optics to control energy and heat in HAZ-prone alloys. Mobile units handle on-site repairs and large, complex tools; development and manufacturing are based in Hanau.
Sigma Laser Systems is aimed at mold makers welding hardening-prone tool steel grades such as commonly used 1.2343.
Precise control is essential. Its 5-axis kinematics handle complex weld geometries while limiting heat input, critical where high carbon content and alloying elements can drive martensite in the heat-affected zone. Super Pulse Technology meters energy precisely to reduce cracking and distortion risk.
Users can choose Nd:YAG or Ytterbium fiber lasers for specific material needs, with Leica 10× optics for fine weld placement. Mobile systems support on-site repairs and minimize downtime, while unlimited component size suits large, complex tools; the equipment is developed and manufactured in Hanau.
