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 perform stable welding that generates little spatter in consumable electrode type gas shielded arc welding by using an arc current pulse current consisting of main pulse current and sub-pulse current. CONSTITUTION:When a base metal to be welded 18 by generating an arc 17 between a consumable welding wire 16 in welding torch 15 and a base metal to be welded 16 under the presence of shielding gas, welding current is set to pulse current constituted of current values 6, 7, 8. In this case, current generating devices 3, 4, 5 are switched by a time 2 to be times 9, 10, 11, 12 to obtain pulse current having main pulse 13 and sub-pulse 14 of smaller current than the main pulse. A droplet is formed at the end of the welding wire by the main pulse current 13, and the droplet is separated from the tip of the wire 16 to a molten pool by the sub-pulse 14. Thus, stable consumable electrode type gas ghielded welding that generates little spatter can be performed.

摘要： PURPOSE:To improve productivity in rolling operation by pouring a high-temp. molten steel into the space formed of the ends of preceding and succeeding billets and copper straps and cooling said steel to solidify on a heat resistant traveling belt then subjecting the billets to continuous rolling. CONSTITUTION:A clearance W is maintained between the high-temp. billets 1 and 2 on the heat resistant traveling belt 8 and the apertures on both sides in the transverse direction are closed by water-cooled copper straps. The molten steel 3 is poured from a vessel 7 for the molten steel into the space formed of the rear end of the preceding billet 1, the front end of the succeeding billet 2 and the copper straps. The vessel 7 is removed upon completion of pouring. The billets 1, 2 are transferred on the belt 8 and the molten metal 3 cools to solidify, thus forming a joint layer 4. The billets 1, 2 joined via the layer 4 are conducted to rolling rolls by the belt 8 and are successively rolled to a product. Since the joining is completed simply by pouring and cooling of the molten steel, the productivity in the rolling operation is improved.

摘要： PURPOSE:To join continuously thick-walled steel materials with high efficiency by forming respectively a sloped recess and sloped projecting part to both ends of the thick-walled steel materials, fitting and coupling the recess and projecting part and hot rolling the fitted and coupled parts thereby pressure welding said parts. CONSTITUTION:The rear end of preceding slab 11 and the front end of a succeeding slab 12 which slabs are thick-walled steel materials are sloped to the angle alpha at which the ends can engage with each other. A recessed dovetail groove A is formed to the rear end of the slab 11 in the transverse direction thereof and a projecting dovetail B engaging with the groove A is formed to the front end of the slab 12. The slopes of the slab 11 and the slab 12 are mated with each other to fit the groove A and the dovetail B to the state of preventing fluctuation in the thickness. While the top and bottom surfaces of the plates 11, 12 are supported by plural guide rollers 13 in a way as to avoid disengagement of the juncture therebetween, the plates are rolled by rolling rolls 13 to roll and join the fitted joint surfaces. The thick-walled steel materials are joined by making successively the above-mentioned operation by which productivity is improved.

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.
