Speicherprogrammierbare (SPS)-Steuerungen,The word laser simply means Light Amplification by Stimulated Emission of Radiation. It gives a basic idea of the principles on which laser devices work, i.e., the generation of a monochromatic, coherent, collimated and intense beam of light. Every device capable of producing a laser radiation, the term laser is associated with that for extension.

Narrow Gap Welding,ding problem of large and thick plates has gradually attracted the attention of researchers. At present, the large and thick plates welding encountered in the manufacturing of thick wall structures are mainly submerged arc welding, electroslag welding and multi-layer multi-pass welding processes.
