摘要： Hot dip Zn-based alloy coated steel sheets (1, 1′) are arc-weld in such a way that (a) a current waveform is a pulsed current waveform in which (i) a peak current and a base current alternate with each other at a pulse period of 1 ms to 50 ms and (ii) an average welding current is 100 A to 350 A and (b) an average welding voltage is 20 V to 35 V. Each of the hot dip Zn-based alloy coated steel sheets (1, 1′) includes a coating layer that contains Zn as a main component and that contains Al at a concentration of 1.0% by mass to 22.0% by mass, and has a coating weight W of 15 g/m2 to 250 g/m2.

摘要： A laser welding method for welding materials having different thicknesses includes abutting two plates having different thicknesses such that one surface of the thin plate and one surface the thick plate are made flush with each other; and thereafter welding the plates by applying a laser beam to abutting surfaces thereof, wherein the laser beam is directed obliquely relative to an abutting end face of the thick plate, a target position of the laser beam is determined on the abutting end face of the thick plate, and a target position depth D on the abutting end face of the thick plate is determined based on the formula t/3≤D≤t where t is a thickness of the abutting end face of the thin plate.

摘要： A vacuum insulation panel manufacturing method that makes it possible to manufacture low-cost, high-performance vacuum insulation panels, and a vacuum insulation panel are provided. This method of manufacturing a vacuum insulation panel (1) involves: a stacking step in which a first metal plate (20) is stacked on one side of an insulating core material (10), and in which a backing member (50) having an opening (51) and a second metal plate (30) having an evacuation port (32) are stacked, with the opening (51) and the evacuation port (32) stacking, on the other surface of the core member (10) in the order of backing member (50) and second metal plate (30) from the core member (10) side; a first welding step for welding outwards of where the core member (10) is arranged in the first metal plate (20) and the second metal plate (30); an evacuating step from the evacuation port (32) to create a vacuum in an inner area which is held between the first metal plate (20) and the second metal plate (30) and in which the core member (10) is arranged; and a laser welding step in which, in a state in which the inner area is made into a vacuum by the evacuating step, the evacuation port (32) is sealed by means of a sealing material (60) and the sealing material (60), the second metal plate (30) and the backing member (50) are laser welded.

摘要： The present invention provides a method for producing a TIG-welded stainless steel tube without adding H2 to a shielding gas, while inhibiting generation of a weld defect. The method is a method for producing a TIG-welded stainless steel tube and includes the steps of bending a stainless steel strip in a width direction so as to butt both edges against each other and TIG-welding the both edges thus butted. A pulse waveform of a pulse frequency of 40 Hz to 300 Hz is used as a current waveform of a welding power source.
