摘要： PROBLEM TO BE SOLVED: To safely and reliably perform welding with an electro-gas arc welding. SOLUTION: An additional wire 20 is inserted from an inserting hole 5a formed at the back side of a molten pool 4 to generate a Lorentz force directing upwards and acting on the molten pool 4 by causing an electric current to flow directed from the side of an arc 3 to the side of a bead 65 located on the back side in the molten pool 4 to which an electromagnetic field is applied by an electromagnetic field generation means 10. The inserting hole 5a through which the additional wire 20 is inserted is provided with a cap 22 formed of ceramics which has high resistance to high temperatures, an excellent insulation performance, and characteristics with which the molten metal forming the molten pool 4 hardly sticks to the ceramics. The additional wire 20 is inserted through a hole 23 formed at the center of the cap 22.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device for magnetically controlled welding for a narrow bevel which can attain proper welding execution and high efficiency welding without generating welding defect such as undercut and overlap even at narrow bevel welding when manufacturing steel shapes structure. SOLUTION: A wire 6 or an electrode 5 is arranged by inserting it in the narrow grove 29 and welding is executed by a welding power source 18 and at that time current 25 is made to flow between a filler wire 7 and a welding electrode 7 in a direction crossing inside of a molten pool 3. Otherwise in the molten pool 3 formed at a post stream side of arc, perpendicular magnetic field 23 is applied to an iron core and further a magnetic field leakage preventing coil 10 is surrounded around an outer periphery of the iron core except a top end thereof. Consequently magnetic lines of force are made to enter the narrow bevel 29 by the iron core 5 and further the magnetic lines of force are made to act only on the molten pool 3 by surrounding the magnetic field leakage preventing coil 10 around the entered iron core 5.

摘要： PROBLEM TO BE SOLVED: To smoothly perform treatment such as peeling and cleaning of paint film and surface oxide even in the case of performing blast treatment using dry ice of low hardness. SOLUTION: Laser beam is pulse-radiated to a subject surface to be treated to form a number of fine holes 31a in only a coating layer such as a paint film on the surface, and dry ice grain is jetted to hole formed parts at high speed after or simultaneously as the fine holes 31a are formed. By wedge effect when the dry ice grain jetted at high speed to advance along a boundary surface between the subject surface and the paint film, and by volume expansion effect of it when it is gasified, coating 31 such as a paint film layer and surface oxide layer can be peeled or cleaned.

摘要： PURPOSE:To shorten a construction period, by a method wherein a work platform mechanism is lifted by jacking-up devices being raised along external board-reinforcing members, following which a set of horizontal beams are stacked in multistage shape and the work platform mechanism is simultaneously raised, and thus blocks of a towerlike structure and horizontal beams are fixed. CONSTITUTION:Internal and external cylindrical blocks 3a, 4a are progressively lifted by a tower crane 1, and the external cylindrical blocks 4a divided and the internal cylindrical blocks 3a are respectively installed at an upper work platform 11a and at a lower work platform 11b. At this time, stoppers 91, 92 for each of guide supports 9 are engaged with a ring 12, securing pins for upper and lower clamping devices each are inserted into pin holes, and thus supporting devices for masts 10 are ready to break away from the ring 12. After that, the work platforms 11a, 11b are lifted by jacking-up devices, the masts 10 are moved to the most upper position and supporting devices for the masts 10 are engaged with a ring 12. During this work, horizontal beams 7 are placed, following which the stoppers 91, 92 are allowed to break away from the ring 12 and the jacking-up devices are lowered by operating and thus the guide supports 9 rise. After that, the upper and lower stoppers 91, 92 are engaged with a ring 12 and the supporting devices for the masts 10 are allowed to break away from the ring 12. Such erecting movements are repeated and a chemney stack is progressively erected.

摘要： PURPOSE:To provide an air cleaning device capable of reducing an energy consumption amount and making its size compact without applying any gas absorption tower, water vapor generating device and secondary cooling device or the like. CONSTITUTION:A cooler 3 cools polluted air fed from a clean room 1 to reduce its moisture condensate, so that water-soluble gas contained in the polluted air is absorbed into the condensate, cleaning the polluted air. A humidifier for the polluted air is installed at an upstream side of the cooler 3, or a gas- liquid separator is installed at a downstream side of the cooler so as to increase a removing efficiency of the polluted air. In addition, a pressure reducing device is arranged in place of the cooler 3, the polluted air is reduced in its pressure to generate the condensate and the water-soluble gas contained in the polluted air is absorbed and removed.
