摘要： PURPOSE:To prevent the occurrence of blow holes and improve joint efficiency by adding a deoxidizer to the groove part in beam-welding of rimmed steels. CONSTITUTION:In welding a rimmed steel with a high energy density and low heat input heat source such as laser or electron beam, powder of a deoxidizer is beforehand dissolved in a solvent of high viscosity in the form of paste and this paste is adhered 3 on the groove part, then welding is carried out. Alternately, the foil 7 of a deoxidizer is beforehand set in the groove part and welding is performed, or a wire for welding 8 contg. the deoxidizer is added into the groove during welding. The similar effect is also obtainable by mixing the powder 6 of the deoxidizer into a shield gas 5 and injecting the same into the molten pool M during welding.

摘要： PURPOSE:To make it possible to perform lining for a wide area easily, by using foils of Ni or a specified Ni alloy as an inserting material when a corrosion-resistant material is fitted as a lining to a steel material by electric resistance welding. CONSTITUTION:A corrosion-resistance material composed of 9-33wt% Ni, 0.4- 1.8% Fe, 1% Mn and 1% Zn and the rest of copper is piled up on a steel material and the electric resistance welding is made on them by using a foil of Ni, an alloy containing 60% Ni and the rest of Cu, or another alloy containing 70% Ni, 16% Cu and 8% Fe, as an inserting material. At this time, the corrosion-resistant material is heated until its melting point comes but the steel is not practically melted, and the corrosion-resistant material and the steel are joined together. The rotary electrode, etc., is used as the electrode at the time of welding. A joining in which solid diffu- sion is utilized can be performed due to the resistance exothermic heat of the inserting material.

摘要： PURPOSE:To make minute the crystal grain of the weld metal, and to prevent the weld zone from cracking, by previously adding the specified necessary amount of V to be added, to at least one of welding wire, consumable nozzle, and auxiliary electrode plate, and by electroslag welding the butt weld zone of two parent metals under the ordinary welding condition. CONSTITUTION:Vanadium is added so as to make the rate of V in the produced weld metal to be 0.05-0.5wt%, in consideration of the dilution rate due to the parent metal and the consumption due to the oxidation of V while the welding work. The molten slag 6 is formed in the space formed by the parent metal 4 and the backing metal 5, and the temperature of the molten slag 6 is raised by the resistance heat caused by the current flowing through the welding wire 1, consumable nozzle 2, auxiliary electrode plate 3, molten slag 6 and parent metal 4. As a result, the welding wire 1, consumable nozzle 2, auxiliary electrode plate 3 and the parent metal 4 are molten, and form the molten metal 7, which solidifies and forms the weld metal 8.

摘要： PURPOSE:To prevent molten metal from drooping from a groove by allowing magnetic force having specified directivity to act on welding current at the time of horizontal position welding and allowing upward force to act on molten metal in the molten pool by electromagnetic induction between the two. CONSTITUTION:Welding current is led flow between a base metal 1 having a groove in horizontal position and energizing tip 11 to generate an arc 18 between the tip of a welding wire 12 and the base metal 1, and a molten pool is formed by melting of the welding wire 12. In this case, a core of magnetic body 15 is placed outside of the energizing tip 11 through an insulator 14, and a coil 16 is wound on it, and current is applied from a power source 17. A magnetic field 21 of the direction shown by the arrow mark is generated by the current, and moving force according to Fleming's left-hand rule is made to act on molten meta in the molten pool 30 by welding current 22. A magnetic field generated by current from a power source 17 is made to alternating field, and upward force 30 is made to act on the molten metal to prevent it from drooping from a groove. Thus, weld metal free from defective welding is formed.

摘要： PURPOSE:To maintain the upper part in the welding space owing to shrinkage on welding at an adequate gap and to permit prevention of the deformation in the adjacent spaces and to facilitate the detaching of a water cooled copper plate by tapering the welding space between a pair of billets facing each other to widen the side where welding ends and inserting a restraining plate in the adjacent space which is not welded. CONSTITUTION:The gap in a welding space 4 is preliminarily made as wide as to allow for shrinkage on welding and a restraining plate 13 formed to a desired size is inserted into the adjacent welding space 4 which is not welded and therefore even if the inside of the space 4 shrinks, stable welding is accomplished. The deformation due to shrinkage of the adjacent space which is not welded is prevented and a water cooled copper plate 6 is easily removed upon ending of welding. The plate 13 is more effective as said plate is provided nearer the rear of the plate 6 and after welding said plate is cut and removed by gaseous oxygen, acetylene, etc.

摘要： PURPOSE:To produce easily and quickly a large-sized steel material by partitioning the space formed of a pair of billets faced to each other by gates and subjecting the partitioned space to electroslag welding while cooling the end face of the gate on the non-welding side. CONSTITUTION:A copper plate 19 formed intenally with cooling water passages 18 is disposed to one end face (the space 152 side which is not welded first) of one gate 12 and a heat insulating material 10 is provided between the gate 12 and the plate 19. Plural pieces of hydraulic cylinders 20 are further interposed vertically between the plate 19 and the gate 12 behind said plate. Cooling hoses 17 are thereafter connected to the passages 18 and the supply of water is started; at the same time, plural pieces of consumable nozzle type electrodes provided with welding wires are inserted into the space 151 partitioned by the other end face side of the gate 12 to perform electroslag welding. A molten metal is then gradually accumulated in the space 151 and the gate 12 is heated and melted by the convection of the molten slag which is heated by the current.

摘要： PURPOSE:To maintain a satisfactory welding condition without generating any blowhole in the stage of semi-automatic welding with nongas arc by emitting an alarm indicating the deviation of the welding current signal in the stage of actual welding from a preliminarily stored correct welding condition when such deviation arises thereby maintaining the wire always at an adequate free length. CONSTITUTION:The relation between a wire feed speed and a correct welding voltage in accordance with the kind and diameter of a welding wire and the welding current ranges I1, I2 in the range of the adequate free length of the wire at a certain feed speed of the wire are preliminarily stored 14. The kind and diameter of a wire 2 are then inputted by a key operation 16, and further the voltage of the feed signal for the wire and the output voltage of a welding machine are set. An arithmetic section 15 is automatically operated upon starting of welding and the voltage signal IV proportional to the welding current is inputted from a detecting section 13 for welding current signal. An alarm signal indicating the need for a precaution is outputted if the above- described signal IV deviates from the stored 14 adequate current range. Said deviation is announced to the welder by the audible sound or display emitted from an alarm device 17.

摘要： PURPOSE:To obtain a press machine housing of high rigidity and strength by cutting out unit block of housing from a composite steel material made by combining and welding plural steel materials and welding the joint plane of each block. CONSTITUTION:Blocks 2, 3, 4 of the size necessary to form a housing are cut out from a large composite steel material made by putting steel materials (a), (b), (c) together and combined by a welding steel (d). A block 5 provided with a member 8 for pressing device at the center is manufactured separately from cast steel. This block 5 and blocks 2, 3, 4 cut out from the composite steel material 7 are put together and combined by welding. By this way, press machine housings stable in quality and shape can be manufactured without causing defects in the core of unit blocks 2, 3, 4, 5.
