摘要： PURPOSE:To reduce the generation rate of undercut and incomplete fusion, by wind-welding a corner of the end part of a member by chamfering, R-finishing or groove-cutting. CONSTITUTION:A corner of the end part of a member 1 in case of wind-welding is brought to chamfering of >=2C, or R-finishing of >=2R. Or with respect to a corner of the member 1 and a range of about 50mm. for the corner, edge preparation of about 45 deg. is executed. In this way, generation of undercut and generation of incomplete fusion of a padding welding route part are prevented, the workability is improved and the reliability is raised.

摘要： PURPOSE:To restrain the area occupied by a depositing metal smaller, to reduce the amount of a filler metal and shorten the welding time by forming the soft toe part becoming the weld zone with its projection in advance at both sides of one end of a bone member. CONSTITUTION:The soft toe part 7 becoming the weld zone onto a skin plate 2 is formed with its projection in advance at both sides of one end of a skelton member 6. The soft toe part 7 has the 1st inclined face 7a inclining so as to increase the plate thickness of the skelton member 6 gradually toward the one end and the 2nd inclined face 7b forming a groove in the space with the skin plate 2 with its inclining so as to reduce the plate thickness of the skelton member 6 gradually toward the one end from the tip of this inclined face 7a, and the cross sectional shape makes an about triangular shape. An adequate R is made on the part (A) connecting to the side face 6a of the bone member 6 by the 1st inclined face 7a and the generation of stress concentration is prevented. The angle theta for the skin plate 2 of the 2nd inclined face 7b is 0 deg.

摘要： PURPOSE:To perform continuously multicircumferential welding without erasing an arc by reversing the moving direction of a welding carriage, which can feed a filler wire from two directions, front and rear, in the weld line direction, so as to overrun upon every one full circumferential welding. CONSTITUTION:A welding carriage 2 is run while regular welding is performed. The carriage is moved forward in a clockwise direction and the movement is continued until an electrode 4 arrives at a point S. Current supply, arc voltage control, vertical position adjustment of a wire and carriage traveling are maintained even after the arrival at the point S and only the wire feed speed is gradually decreased. The current is decreased with slight delay from the decrease in the wire feed speed and the decreasing state is continued even after the feeding of the wire is stopped. The wire is retreated by a prescribed distance in synchronization with the decrease of the current to the arc holding current. The carriage 2 is stopped where it overruns by a required distance, then the carriage is moved backward. The carriage 2 is again stopped where the electrode 4 coincides with the start point S and the current to the electrode is increased up to the initial current. The wire is fed from the 2nd feeder 3' in the backward movement.

摘要： PURPOSE:To carry out all position automatic welding and improve working efficiency greatly by forming beads all over the circumference of a pipe by padding weld reciprocating a welding torch at the predetermined distance in parallel to the axis. CONSTITUTION:A welding head stops on a movable rail. An electrode moves by a given length a from p to q in parallel to the axis and then moves by the determined length a in the opposite direction of the previous from r to s. Then the welding head moves by a given distance b from s to t in the circumferential direction on the rail. The above mentioned parallel and reciprocating motion is repeated in the form of an oscillating curve. On the whole the welding head moves in the circumferential direction and beads with the width of a are formed all over the surface of the pipe. If pulsing current is applied to a welding electrode, welding of not only vertical upward and downward but also overhead position can be carried out greatly easily.

摘要： PURPOSE:To perform the fillet welding along a weld line at a high speed by detecting a welding current or the arc voltage of two welding wires and comparing the values to detect a deviation of torches from the weld line and sliding the torches to correct the deviation. CONSTITUTION:The welding currents flowing between the tips of the respective welding wires 8 and 8', and base metal 1 are detected by ammeters 13 and 14 respectively the these detected currents are sent to a comparison computing element 15. The comparison computing element 15 compares the detected currents and in case the difference between both the detected currents is positive or negative, a slide motor 7 is rotated normally or rotated reversely by a normal and reverse rotation commanding device 17 to slide and move a sliding device 6. The welding torches 4 and 4' are moved in a direction to cross at right angles with the weld line 2 together with the welding wires 8 and 8' and stopped at the position where intervals between the tips of the respective welding wires 8 and 8' and the base metal 1 become equal. The tips of the welding wires 8 and 8' are advanced along the weld line 2 without weaving to perform the fillet welding at the high speed by performing the above-mentioned control continuously.

摘要： PURPOSE:To obviate lack of fusion, and to form a smooth joint bead by making a welding current high, when changing to a stationary bead part from a lap bead part. CONSTITUTION:In case of a symmetrical sequence welding of a joint part, a welding condition of a lap bead part 1a and 2a is set so that deposited metal quantities W1a, W2a of a unit length become smaller against deposited metal quantities W1b, W2b of a unit length of stationary bead parts 1b, 2b. Also, it is determined so as to become a relation of W1a+W2a=W1b=W2b. Moreover, in the welding condition, a switching current difference of a welding current is set to >=30A. In this regard, the welding condition is changed by one stage. According to this bead joining method, a lack of fusion in a part X is obviated, and a smooth joint bead can be formed.
