摘要： The present invention relates to an automatic welding system for a corrugated membrane sheet of a membrane type liquefied-gas cargo hold, a structure for guiding and fixing an automatic welding apparatus for a corrugated membrane sheet of a membrane type liquefied-gas cargo hold, and a structure for guiding an automatic welding apparatus for a corrugated membrane sheet of a membrane type liquefied-gas cargo hold. When a corrugated membrane sheet is welded, a cross-anchor strip having a fixing groove is installed on a portion where longitudinal and lateral anchor strips, which are attached to the upper surface of a heat insulating panel on which the corrugated membrane sheet is mounted, cross each other, which makes it possible to install a welding guide that supports the automatic welding apparatus and guides movement of the automatic welding apparatus using the fixing groove, thereby stably performing automatic welding on the corrugated membrane sheet.

摘要： The purpose of the present invention is, in gas shielded arc welding using an active gas and flux-cored wire with primer-coated steel plates as a base material, to suppress occurrences of poor appearance in welded parts caused by pores originating in the primer. A welding method for a welded article positions a first steel plate and a second steel plate formed from primer-coated steel plates in a T shape and welds each of corner parts formed in two locations. Using flux-cored wire (100), which is formed by filling the inside of a steel outside skin with flux, and a shielding gas (carbon dioxide gas), a welding pool (400) is formed in the corner part by supplying a welding current to the corner part via an arc from the flux-cored wire (100) by means of the shielding gas; additionally, an alternating magnetic field is applied to the welding pool, and the welding current and the alternating magnetic field are set such that the welding current (A) and the magnetic flux density (mT) for the alternating magnetic field have a relationship of 20000 ‰¤ welding current × magnetic flux density ‰¤ 30000.

摘要： In a plate assembling step, a gap (5) is formed between a leading end portion (3A) of a groove (3) provided on an upright plate (2) and a lower plate (1). In this state, in a first welding step, an arc is generated from a welding wire (7) toward a back surface (3C) side of the groove (3) through the gap (5), to form a satisfactory penetration bead (8) on the back surface (3C) side of the groove (3). Next, in a second welding step, the welding wire (7), the lower plate (1), the groove (3) of the upright plate (2) and the penetration bead (8) are fused to form a first-layer welding bead (9), thereby firmly joining the lower plate (1) and the groove (3) of the upright plate (2). In this case, since the first welding step and the second welding step can be performed continuously after performing the plate assembling step, it is possible to enhance workability at the time of welding the lower plate (1) and the upright plate (2).

摘要： The weld line-detecting method of the present invention is a weld line-detecting method when fillet welding by an industrial robot including a welding torch is taught. The welding torch on which an angle sensor having a contactor is attached is moved toward a welding object, angle information obtained when the contactor is in contact with the welding object is transmitted to the industrial robot, and the industrial robot moves the welding torch based on the angle information so that the angle of the contactor becomes zero. These operations are repeated, and the welding torch is moved toward a fillet part along the surface of the welding object. When the contactor arrives at the fillet part of the welding object, a signal indicating that the contactor is pressed in the axial direction of the contactor is transmitted to the industrial robot. Thus, the industrial robot detects that the contactor arrives at the position to be welded on the weld line.

摘要： The objective of the present invention is to provide a similar-metal-composition welding solid wire, and weld metals therefor, with which both excellent bead shape and high ultralow-temperature toughness for the weld joints can be achieved when welding 9% Ni steels together by means of a high-efficiency MIG welding method. A fixed ratio of a REM and O are included in a similar-metal-composition welding solid wire of a 9% Ni steel base material, and oxygen is supplied in a trace amount in a range that does not hinder the ultralow-temperature toughness of the weld joint (1a) but that is capable of forming fine REM oxides in the weld metal (3) and of controlling the weld metal to produce an excellent bead shape. In addition, both Al and Ti are regulated and an argon gas that contains little or no carbon dioxide gas is used as the shield gas in the MIG welding method. Thus, both an excellent bead shape and high ultralow-temperature toughness for the weld joint (1a) can be achieved.
