Steel tube with a circumferential laser weld seam
SISMA SL 35/50/80 is a series of pulsed Nd:YAG flash-lamp laser sources for automatic welding at high speed and precision, with fibre beam delivery, water cooling and Cruise Control on the PLUS version.

SISMA SL is a series of laser systems for automatic welding, built for high speed and precision. Its main component is a Nd:YAG flash-lamp laser source developed by SISMA.
The laser light is delivered through an optical fibre, available in several sizes, and a water cooling system keeps the pulses constant and repeatable. The PLUS version adds Cruise Control, which keeps the energy of each pulse stable under harsh conditions.
Three sizes are offered, SL 35, SL 50 and SL 80, in PLUS and GO versions. Maximum pulse energy is 25, 30 and 70 J, with pulse durations from 0.3 to 25 ms and pulse frequencies up to 50 Hz, on a 230 V single-phase supply.
The SL sources are offered for automatic welding in jewelry and industry.
