摘要： PURPOSE:To prevent electric shock accidents under the noload voltage in the touch sensing system of underwater dry arc welding, by supplying a preparation alarm current to the audiovisual alarm circuit interposed for the base metal and the electrode circuit at the noload voltage applying time and by cutting of this current in the arc start enable state. CONSTITUTION:In TIG welding device 1 as an underwater dry arc welding device, the cathode and the anode are connected to the electrode of torch 2 and material 3 to be welded through circuits 4 and 5, respectively, and relay circuit CR6, buzzer CR 7 as an audiovisual alarm circuit, and relay 8 are interposed in parallel between circuits 4 and 5. When a noload voltage is applied across electrode 2 and material 3 to be welded, buzzer 7 is operated through contact relays 6 and 8 to report voltage applying to the worker. When the alarm current is applied to said alarm circuit, interclock mechanism 9 is operated to lock welding start device 10 electrically. Next, when electrode 2 is brought into contact with material 3 to be welded to perform arc start, the alarm circuit is closed, and the worker operates start switch 11 to perform prescribed arc welding by device 10.

摘要： PURPOSE:To accurately weld the weld line ruggedly displacing in longitudinal directions and improve workability by displacing a welding desk in the longitudinal directions following up the weld line. CONSTITUTION:In the case of welding the weld line 9 displacing longitudinally by a distance l1 between a convex face 10 and a concave face 11 in a horizontal direction, if the detecting end 16 at the end of one detecting rod 15a out of the detecting ends 16 of a detecting mechanism 13 displaces relatively with the detecting end 16 of the other detecting end 15b, the extent of this displacement is detected by a longitudinal displacement detecting mechanism 13 which in turn sends the signal to a longitudinal driving source 12 and a carriage driving mechanism 2. When the longitudinal driving source 12 receives the signal, it closes a clutch 18 to rotate the driving source 19 in the arrow F direction, by which a sliding plate 26 is advanced in the arrow B direction via a rack plate 23 meshed with a pinion 20. Thereupon the motion is transmitted to a sliding plate 29 via a spring 32 to advance the welding desk 4 by the displaced portion so that the welding head is accurately responded to the weld line 9, whereby proper welding is accomplished.

摘要： PURPOSE:To make a welding with minute fillets possible to reduce the thermal distortion, by welding a lateral plate and a longitudinal plate after forming a groove, which has a form required to result a melted state to give to the lateral plate an almost equal thickness to the longitudinal plate. CONSTITUTION:A groove 3 having a bottom part 1b having a thickness W approximately equal to a thickness t1 of a longitudinal plate 2 and a thickness t2 is formed on a lateral plate 1 on the extension of the longitudinal plate 2 brought into contact with the lateral plate. Welding is started from the groove 3 to weld the lateral plate 1 and the longitudinal plate 2 under the state where minute fillets 4 are provided. Thus, a T-shaped welded joint having minute fillets is obtained.

摘要： PURPOSE:To accurately perform the welding of the works making curvature biasing deformation by swiveling the welding desk forward and backward in follow up to the weld line by the detecting signal of a curvature biasing detecting mechanism. CONSTITUTION:When the detecting end 20 at the end of one detecting rod 19a of a curvature biasing detecting mechanism 17 displaces relatively with the detecting end 20 of the other detecting rod 19b, the mechanism sends the detecting signal to a swivelably driving source 16 and a longitudinal driving source 12 as well as a carriage driving mechanism. Upon receiving the signal, the swivelably driving source 16 revolves the driving shaft 22 of a swiveling mechanism 21 forward in the arrow H direction to revolve a sector swivel 27 forward in the arrow C direction, thereby advancing a welding desk 4 via a driving mechanism 13 while swiveling the welding desk 4 in the same direction, and accurately welding the weld line along its curvature R1. In the curvature R2 part, the driving shaft 22 of the swiveling mechanism 21 is revolved backward in the arrow I direction by the detection signal to oppose the welding head accurately to the curvature R2 of the weld line while resetting the secctor swivel plate 27 and the welding desk 4, whereby the proper welding is accomplished.

摘要： PURPOSE:To weld a base metal having a groove gap of even 2-6mm., with small thermal strain, by welding the I-shaped groove formed in part of welding surface of a base metal by electron beams, and radiating electron beams to the extremely small groove formed continuously to the I-shaped groove to build up welding. CONSTITUTION:The end faces of protrusions 3, 3 projecting in the axial direction, which are formed preliminarily, are set butt to butt in the central part of the welding surface 2 of base metals 1, 1 to form an extremely small gap 4 of about 2-6mm.. In thisf state, the materials 1, 1 are set opposedly to each other. By butting the end faces of the protrusions 3, 3, an I-shaped groove 5 having a groove gap of 0-0.1mm. is formed in the central part. Welding is then performed by radiating electron beams 6a to the groove 5. Then, the end part of a wire feeder 7 is inserted into the gap 4, and beams 6a are radiated to the wire 8 being fed successively to build up welding 10 consisting of plural layers 91, 92-9n while rotating the materials 1, 1, for example, in the direction of 5a, so that the materials 1, 1 may be completely welded.
