JK 2000
Laser Processing System


JK Series — the top choice
The JK 2000 offers high-speed welding, cutting and surface treatment in most metals, even highly reflective materials such as aluminum.

JK 2000 — an everyday production tool
Compact and sealed to NEMA12/IP55, the JK 2000 is already field proven as an industrial workhorse, working “around-the-clock” in the toughest factory environments. This system provides efficient modular construction facilitates for rapid set-up and easy maintenance.  This system is user friendly.

Classic applications
Automotive industry:  JK 2000 is ideal for on-line applications such as welding the roof to the side panel and welding tailored blanks. High speed welds are produced with good ductility. Precision fiber optic beam delivery simplifies machine design–reducing up-front investment costs.  Other applications include: tube welding for household radiators and other domestic fittings, and welding in the industrial and domestic pump industry. The JK 2000 laser processing system also handles deep section welding for the nuclear industry. Spatter free joints can be produced within seconds reducing the manufacturing costs and scrap rate. The flexible fiber optic cable allows the process to be performed remote from the laser source.
Nuclear industry: The JK 2000 laser processing system expertly manages deep section welding for the nuclear industry. Spatter free joints are produced within seconds (reducing the manufacturing costs and scrap rate). With the flexible fiber optic cable, the process can be performed remotely from the laser source.
