摘要： PROBLEM TO BE SOLVED: To easily install a clamping press-fitting device for a pipe even in a narrow work space by reducing its weight and miniaturizing it to perform joining and press-fitting of a steel pipe pile continuously.
SOLUTION: An inner peripheral face of the steel pipe pile 40 is held by a lower clamp device 6 and an upper clamp device 5 of the clamping press-fitting device 2 to move it easily into the narrow work space having an existing structure 42. When joining the steel pipe piles 40, an inner peripheral face of a steel pipe pile 40b to be joined by the upper clamp device 5 is held, and an inner peripheral face of a steel pipe pile 40a press-fitted into the ground by the lower clamp device 6 is held to weld them in a flush manner. When press-fitting the joined steel pipe piles 40 into the ground, a flange 27 for receiving reaction force in a holding mechanism part 9 is applied and pressed to the existing structure 42 to drive a hydraulic cylinder part 7, and holding and release of the inner peripheral face of the steel pipe pile 40 joined by the lower clamp device 6 are repeated for press-fitting.

摘要： PROBLEM TO BE SOLVED: To prevent a welding transformer from burning by shutting off welding heat transferred from a welding heat source to the welding transformer with a simple constitution, and also to improve a working efficiency.
SOLUTION: When a welding surface is flash-welded while supplying current onto members 1a, 1b to be welded form the welding transformers 5a, 5b, the welding heat generated at a weld zone is cooled with heat shut-off plates 6 consisting of water-cooling copper plates arranged on the surfaces apt to affect the welding heat of the welding transformers 5a, 5b to prevent the high temperature welding heat from being transferred into the welding transformers 5a, 5b, whereby suppressing the temperatures rising of the transformers 5a, 5b due to the welding heat.

摘要： PROBLEM TO BE SOLVED: To simply correct dislocation between joining steel materials or deformation of the joined end parts in the steel materials in a short time and to prevent development of the dislocation between the joined steel materials or the deformation during welding.
SOLUTION: When an H sectional steel 1 is flash-welded, restricting members 2 are inserted from both sides of flange portions at both end parts in the H sectional steel 1 set to a frame and fitted to positions apart at a constant distance from the joining end parts. Thereafter, respective wedges 6 are driven in between respective pushing members 4 in the restricting members 2 and flange portions 11 in the H sectional steel 1, and the dislocation between the joined steel materials is corrected, and centering of the joining H sectional steel 1 is performed, and the welding is applied under the state of restricting the flange portions 11 in the H sectional steel 1 with the restricting members 2 and the restrictive wedges 6.

摘要： PROBLEM TO BE SOLVED: To surely collect produced weld fumes regardless of the direction of a welding torch.
SOLUTION: The weld fume collecting apparatus 10 collects weld fumes caused accompanying welding which is performed while a truck with a welding torch attached runs along a guide rail 3 installed on a workpiece 1. A surface facing the workpiece 1 is opened in the apparatus to mount a collection box 11 surrounding the periphery of the welding torch on the truck. Then, in the collection box 11, there is installed a connecting part 17 which is communicated with the inside of the collection box and is connected to a means for sucking the weld fumes.

摘要： PROBLEM TO BE SOLVED: To stably form a finish bead of high quality in which ruggedness on the surface is reduced in horizontal welding, and to efficiently perform the welding by reducing a welding operational time.
SOLUTION: When a finish bead is formed, from the side of an upper plate 2 on the surfaces of beads 5a to 5d stacked at passes (a) to (d), a bead 5e and a bead 5f are successively formed, the sagging lower parts of the preceding beads are remelted, and further, the height of excess metal is reduced by the action of gravity, thus the number of passes upon the formation of the finish bead is reduced. Further, since the excess metal of the finish bead is reduced, and the depth of the trough in the superposed parts of the bead 5e and the bead f is reduced, the finish bead can be made flat, and welding of high quality can be performed. In this way, a repolishing operation for the finish bead can be remarkably reduced.
