Abstract: Methods are provided which comprise the steps of: a) emitting through the cutting head of the laser cutting machine a focused laser beam that does not cut or etch the material of the tube; b) moving the cutting head along a given scanning direction; and c) while the cutting head is moving along the scanning direction, detecting through suitable sensors the radiation reflected or emitted by the tube and establishing point by point, on the base of the signal provided by these sensors, the presence or absence of the material of the tube.

Abstract: A welding system (10) which allows a single welding operator to perform quick, easy and high quality vertical welds comprises a welding fixture (12) with a pair of opposing, positionally adjustable welding shoes, and lock screws for attaching to a workpiece (56) such as an I-beam. Welding fixture (12) is located adjacent the end of an articulating boom (20), and includes a welding torch (14) and oscillator (48). A rotary straight wire feeder (18) removes the cant and helix from welding wire as it is fed to the welding torch (14). The welding torch (14) prevents welding wire from fusing to a guide tube. A distributed welding control system comprising a plurality of controller modules (46, 48, 50, and 52) is interfaced with a common bus (54) and allows a welding operator to program automated welding cycles for various welding operations. The welding system (10) is particularly useful for installing stiffener plates (58) onto structural beams (56).

Abstract: A laser processing machine includes a work head, a platelike work working table for processing a plate-like work, a rod-like work working table including a rod-like work holder for processing a rod-like work, and a work area in which the work head is movably provided. The plate-like work working table is provided movably from one side of the work area into the work area. The rod-like work working table is provided movably from another side of the work area into the work area that is opposite side of the one side. According to the laser processing machine, when switching over between a processing of a plate-like work and a processing of a rod-like work, it is needed only to move/evacuate the plate-like work working table and the rod-like work working table to/from the work area, so that the switching-over operation can be easily done.
