摘要： PURPOSE:To obtain a good joint part without separating beams in electron beam welding of metallic sheets having high surface tension. CONSTITUTION:The butt parts of the sheets 1, 2 consisting of an Ni-Ti alloy or Ni-Cr-Fe alloy are worked to a shape to allow butting at 30 to 45 deg. angle theta(the upper limit is 60 deg. in the case of an Ni-Cr-Ti alloy) and thereafter, these parts are subjected to electron beam welding at the time of subjecting the above-mentioned sheets to the electron beam welding(EBW). The butt parts are preferably partially fixed by resistance welding prior to the electron beam welding. This method is suitable for production of cylindrical pipes and the production of a composite material formed by laminating another metal into the cylindrical pipe is possible.

摘要： PURPOSE:To perform a series of stages for flux cored wires continuously and to improve productivity by packing a flux in a tube while subjecting the seam of a steel hoop formed to a tubular shape to induction welding and drawing the tube. CONSTITUTION:A belt-like wire W1 is supplied from a storage part, and is run in parallel in the part of guiding rolls 1. After the direction is changed to a downward inclining direction by a guiding roll 2, the wire is formed to a semi- circular wire W2 by curving rolls 3. Further, while the wire is formed to a tubular shape by means of tube forming rolls 4, the seam right after the same is welded with an induction coil 5 and a nozzle extending from the bottom end of a hopper 6 is inserted into the formed tube and a flux is sprayed and packed therein from the nozzle. The tube is passed through squeezing rolls 7, and if necessary, the tube is passed through a deburring device for the induction weld zones; thereafter, the tube is conducted to a die 8, by which the tube is drawn to a prescribed size and the product is obtained.

摘要： PURPOSE:To gather, preserve, and process freely large-capacity high-speed data, by providing first and second storage means for storage of input data, a means for processings of data, and a means which transmits data to a large-capacity processing device. CONSTITUTION:The welding signal from a welding machine is inputted to a waveform storage device 1, and the device 1 converts the input signal to a digital quantity, and data obtained as the result is supplied together with a clock signal for strobe to a bulk memory controller BMC 2. The controller BMC 2 stores this data in a bulk memory 3 and outputs stored data to a computer board 6. The computer board 6 stores input data in a floppy disc 9 by the control signal from a CPU 7 and executes various statistical processings on a basis of stored data, and processing results are sent to a terminal/hard copy device 11 through an interface I/F 10 for communication to obtain the hard copy and are sent to a large-capacity processing device 13 as required to analyze data in the device 13.

摘要： PURPOSE:To carry out heat radiation of an earth electrode efficiently and make the electrode highly corrosion resistant. CONSTITUTION:An earth electrode 10 is made to have a center part 11 made of pure nickel having no less than 80W/m.k thermal conductivity at room temperature and the most outer layer made of a corrosion resistant nickel alloy having no more than 20W/m.k thermal conductivity or to have multilayered coatings of at least two kinds of metals 12, 13, 14 on the outer circumference of the center part without the most outer layer. As a result, the earth electrode can have excellent heat radiating properties and corrosion of the multilayered materials is prevented.

摘要： PURPOSE:To join a metallic member and a metallic net member with good joinability by subjecting the metallic member to electron beam piercing welding to form a reinforcement bead of weld on the rear surface side and filling the gap part of the metallic net member with the reinforcement bead of weld. CONSTITUTION:The metallic member 1 and metallic net member 2 having prescribed thicknesses are joined. The metallic net member 2 is disposed on the rear surface side of the metallic member 1 at this time. The metallic member 1 is irradiated with an electron beam EB and is subjected to the piercing welding. The reinforcement bead of weld is thereby formed on the rear surface side of the metallic member 1 and the gap part of the metallic net member 2 is filled with this reinforcement bead of weld. The metallic net member 2 is disposed on the rear surface side of the metallic member 1 and a metallic backing metal 3 is placed on the substrate 2. The metallic backing metal 3 is then subjected to the electron beam EB piercing welding. The two members are welded in this way without impairing the shape of the metallic net member.
