摘要： PURPOSE: An optical system for a laser-ultrasonic oscillation is provided to condense a high power laser pulse to the small size in an effective location by using the Fresnel lens and a dichroic mirror. CONSTITUTION: A prism refracts a plurality of laser beams radiated from a plurality of optical fibers(100a,100b,100c). The beam of a laser pulse refracted through the prism has the same path with a beam radiated from a virtual same light source. A condensing lens(220) condenses the beams of a plurality of laser pulses refracted in the prism to the specific location of an object material. A Fresnel lens condenses the beams of laser pulses of the optical fibers to the specific location of the object material(300). A dichroic mirror is installed between the optical fiber and the Fresnel lens. The dichroic mirror condenses the scattered light of the laser beam scattered in the specific location of the object material to the specific location.

摘要： A method and appts. are claimed for electroslag welding build-up of cylindrical elements, e.g. mill rolls, in which polyphase current is supplied to consumable electrodes(12) provided around a roll (10). Electrode sizes and numbers are such that the roll and mould(17) distance for the electrode is within 30 mm and the combined electrode width is at least 10% of the mold circumference, e.g. for 100mm build-up of a 100mm dia. roll, there are 6 electrodes at least 40mm thick and 50mm wide. During buildup, molten metal(13) from a separate source and suitably of the same compsn. as the electrodes is added to the molten padding pool at a rate, e.g. 5-30 kg/min.
