摘要： Apparatuses and methods for detecting multilayer multipass welding trajectory are disclosed. The apparatus includes an imaging component, a first and a second directional light source group, a structured light source and a control and processing component. The imaging component is disposed in front of a welding gun and above a weld pass. The first and the second directional light source group are disposed symmetrically above the weld pass and at two sides of the weld pass. The structured light source is disposed above the weld pass. The control and processing component is configured to control the imaging component to capture an image of the workpiece surface separately when the first directional light source group, the second directional light source group or the structured light source emits the light to the workpiece surface and to obtain a multilayer multipass welding trajectory according to the images.

摘要： A method for welding two or more conduits includes aligning end portions thereof in an abutting relationship to define a gap. The method includes performing a spatter free root weld along the gap to configure a root layer while the inner circumferential surface side is unobstructed. After the root weld is complete, an outward thrust is applied along the inner circumferential surfaces of the conduits. During the application of the outward thrust, a filler weld is performed along the gap to fill the gap and to facilitate shrinkage of the filler and root weld materials longitudinally and radially outward while preventing pressing out of the filler and root weld materials radially inward of the inner circumferential surface.

摘要： A joint unit includes a first metal pipe, a second metal pipe, and a joint portion (a region including a joint interface at which the end faces of the first and second metal pipes are joined to each other. At the joint portion, an outer circumferential bead portion protruding toward the outer circumference side and an inner circumferential bead portion protruding toward the inner circumference side are formed. The difference between the width of the outer circumferential bead portion (the width L1 of a grinding portion and the width L2 of the inner circumferential bead portion in a direction from the first metal pipe toward the second metal pipe is equal to or smaller than 40% with respect to the average value of the width L1 of the outer circumferential bead portion and the width L2 of the inner circumferential bead portion.
