摘要： PURPOSE:To obtain an intact weld zone having a uniform bead shape by providing a coil near the weld zone to generate a shifting magnetic field, and applying the thrust in the direction opposite from the outflow direction of a molten metal on said metal that flows downward as a pipe inclines in its position according to its rotation. CONSTITUTION:A welding position 15 where a steel hoop 7 and a spiral pipe 14' contact with each other is internally welded by a welding torch and a shifting magnetic field heading toward the rotating direction (b) of the pipe is generated from a magnetic field coil L attached near a molten metal 22. As a result, the thrust in a direction F is acted on the molten metal 22 moving diagonally upward according to the rotation of the pipe and the outflow of the metal 22 going to flow downward by its own weight is prevented by such thrust. An electromagnetic stirring effect by the shifting magnetic field is generated in the metal 22 in this stage. The formation of a recess in the weld bead of the spiral steel pipe is thus averted and the intact weld zone is obtd.

摘要： PROBLEM TO BE SOLVED: To provide a method by which welding is automatically performed by preventing interference and separation of a shield nozzle and a workpiece even when it is the workpiece the joint angle of which is varied.
SOLUTION: This method includes: a step (S105) where the reference orbit information of a welding torch is generated on the basis of the design data of the workpiece; a step (S107) where the amount of deviation in position of the welding torch to the workpiece mounted actually in the welding position is acquired by touch sensing to the workpiece; a step (S109) where actual orbit information is manufactured by correcting the reference orbit information on the basis of the amount of deviation in position of the welding torch; and a step (S111) where welding is performed by controlling the orbit of the welding torch on the basis of the actual orbit information. The welding is performed while bringing the shield nozzle into contact with a fillet weld joint part, the reference orbit information is generated as the welding is performed while bringing the shield nozzle into contact with the workpiece and the amount of the deviation of the welding torch is acquired by bringing the shield nozzle into contact with the workpiece.

摘要： PROBLEM TO BE SOLVED: To attain a flexible and smooth friction stir joining when base metals are subjected to the friction stir joining using a bobbin tool by controlling heat inputs on both the surface and back sides in the joints of the base metals.
SOLUTION: In the friction stir joining, frictional heat is inputted to the respective joints of base metals from the surface side and the back side with them held, and, by the plastic flow of the joints, joining is performed. In this case, the joining is performed so that the frictional heat inputted to the joint close to the surface side and the frictional heat inputted to the joint close to the back side are independently controlled. For independently controlling the frictional heat inputs to the joints close to a back pressure member 10A and to a surface pressure member 10B, the pressure to the joining face close to the back pressure member and the pressure to the joining face close to the surface pressure member are allowed to independently be controlled, or the rotational speed of the back pressure member and the rotational speed close to the surface pressure member are allowed to independently be controlled, or at least one of the back pressure member and the surface pressure member is provided with a heater or a cooling mechanism.

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： PURPOSE:To apply to joint welding of all kinds of steel tubes and to improve its efficiency by attaching a copying tube having an end face parallel to the weld line and of the same shape and moving a welding torch so as to follow the end face. CONSTITUTION:When the welding device is started, a driving pinion 7a rotates, and a truck 7 is moved along a rail 6 through a rack 6a. With shifting of the truck 7, a sensor attached to a copying shaft 8 detects the copying end face 4 of a copying tube 5, and the copying shaft 8 moves vertically while following the copying end face 4. At this time, as the copying end face 4 and weld line 3 are parallel and of the same shape, the welding torch slaways shifts on the weld line 3.
