摘要： PROBLEM TO BE SOLVED: To provide a storage container for storing waste which has a gas valve for injecting and sealing an inactive gas after storing the waste and causes no leak of the gas in the welding of a seal at an inlet of the gas valve.
SOLUTION: The storage container 1 for storing the waste is made by placing the gas valve 3 in an upper lid 2 of the storage container 1. The gas valve 3 has two upper and lower chambers 4 and 5. In the upper chamber 4, a bar-shaped valve 8 pressed against a through hole 12a formed in an upper plate 12 of the chamber 4 by a spring 7 is placed. In the lower chamber 5, a spherical valve 10 pressed against a through hole 14a formed in an intermediate plate 14 dividing the upper and lower chambers 4 and 5 by a spring 9 is placed. Moreover, the gas valve 3 is constituted by forming a gap (g) between a protrusion 8d at the lower end of the bar-shaped valve 8 and the spherical valve 10. When a gas is injected, the gas valve 3 is opened by allowing the protrusion 8d of the bar-shaped valve 8 to push down the spherical valve 10. In the welding of the seal, each of the valves 10 is closed with the gap (g) by being pushed up with the springs 7 and 9.

摘要： PROBLEM TO BE SOLVED: To provide a method for always generating an arc between a work and a tip of a wire and remarkably reducing generation of spatter. SOLUTION: In the consumable electrode arc welding method for conducting the welding while feeding a wire charged with a voltage, and generating an arc between the tip of the wire and the base metal, upon starting an arc, first the wire 2 is fed with a lower speed, while a voltage is charged to it, so that the tip of the wire 2 is brought into contact with the base metal 3 to make an electric current flow. Within 50 ms after detecting the current to start flowing, the wire 2 is retracted so as to be made apart the mother metal 3 by 1-10 mm. After confirming that the arc 6 is formed, the wire 2 is fed with a speed set for welding. Thus the time period can be made shorter for an excessive short circuit current to flow through the contact of the wire 2 with the mother metal 3. In this way, the wire 2 between a power supply tip 1 and the mother metal 3 is not heated until it is softened, therefore a large volume of or large size of spatter is prevented from being generated even if a sudden gas expansion may be generated by the generation of arc 6.

摘要： PROBLEM TO BE SOLVED: To decrease the possibility of the instability of an arc due to a magnetic blowing caused by a wire electric current. SOLUTION: The hot wire welding equipment (TIG welding torch) is provided with a hot wire TIG welding power supply where the energizing term of a heating electric current for one or more added wires 10 is controlled by being synchronized with an oscillation phase of a TIG arc which oscillates in a wide range where the amplitude is 10 mm or greater and the frequency is 10 Hz or greater. In this case, when two or more wires 10 are used, an energizing time is controlled so that each of the wires 10 is not energized simultaneously and a power supply transformer is so constructed as to supply one or more independent wire heating currents. The energizing term of each heating electric current supplied to plural added wires 10 is controlled to stabilize the magnetic blowing condition of the arc and multiple outputs are available from a single power supply by preventing the simultaneous energizing.

摘要： PROBLEM TO BE SOLVED: To enable vertical upward welding of a narrow groove in a thick planar structure by synchronizing the movement of the wire with that of the welding torch. SOLUTION: With a welding torch 6 on the left side in a narrow groove 10, if a roller 4 is on the left of the wire feeding unit 1, the wire 8 is supplied to the torch 6 along the outer diameter of the roller 3; therefore, a propensity for bending to the left is imparted to the wire 8, which comes out from the torch 6 while facing to the left. Consequently, the tip end of the wire 8 can be aimed at the corner 17 on the left face of the narrow groove 10, enabling the welding of the left face of the groove 10 without tilting the torch 6. With the torch 6 on the right side in the groove 10, if the roller 4 is on the right of the feeding unit 1, the right face of the groove 10 can be welded in the same action as written above. Incidentally, the wire feeding unit 1 is moved horizontally by an oscillating mechanism 11, with the center part of the groove welded during this horizontal movement.
