摘要： A method for limiting fitting distortion when welding a fitting to an in-service pipeline—where the fitting includes a thick, longitudinally extending, seam located between fitting halves—involves welding, on each side of the fitting, a middle third section of the seam in a pyramid-like fashion using an inward progression starting from an end of the middle third section along a profile of a seam bevel, and welding outer third sections of the seam using an outward progression from an end adjacent to the middle third section along a profile of the seam bevel. The welding of each of the three sections per side includes a temper bead welding technique of at least two layers to provide stress relief in lieu of traditional post weld heat treatment.

摘要： The disclosed apparatus, systems and methods relate to the design principles for forming a welded joint between two sections of tubing or pipe. The material at the end portion of a first section of tubing to is folded inwardly to create a support surface. This support surface improves the ability to weld light gage material with traditional arc welding and it creates conditions to allow brazing to be as strong as traditional arc welding by using A shaped piece of filler material which is located at the intersection between the support surface of the first section of tubing and a side wall section of the second section of tubing. While holding together the first and second sections of tubing with the filler material, heat is applied at the intersection at a temperature and for a duration sufficient to melt the filler material and form the 3t joint.

摘要： A vehicular differential device includes a differential case, a ring gear, and a welded portion positioned on an abutting surface where the differential case and the ring gear are in contact with each other. The welded portion is configured to join the differential case and the ring gear for integral rotation of the differential case and the ring gear around a rotation axis of the vehicular differential device. The welded portion includes a plurality of welding surfaces positioned at predetermined intervals along a circumferential direction around the rotation axis.

摘要： A heat-weldable weld fitting that has a cylindrical fitting main body portion. The cylindrical fitting main body portion includes an outer periphery including a first end portion, a second end portion, and a middle section between the first end portion and the second end portion, and positioning scales formed at equal intervals in a peripheral direction of the second end portion of the outer periphery of the fitting main body portion. The first end portion being configured to be heated by a heater and is welded to an end portion of another weld fitting. The positioning scales are configured to define an angular portion of the weld fitting relative to the welding apparatus at the time of welding the first end portion to the first end portion of another weld fitting by matching the positioning scale with a reference mark provided on the clamp portion of the welding apparatus.

摘要： A weld joint assembly is provided. The weld joint assembly includes a first structural member having a first thickness. The weld joint assembly also includes a second structural member having a second thickness. The first thickness is different from the second thickness. The second structural member is connected to the first structural member through a weld joint. A plate is connected to the first and second structural members through the weld joint. The plate has a third thickness. The plate extends and abuts a surface of one of the first and second structural members and is welded thereto at outer edges of the plate leading away from the weld joint. At least a portion of the outer edge of the plate that is opposite to the weld joint is free of attachment to the surface.

摘要： A structural member includes a body having a first surface, a second surface, and an end surface at an end portion of the structural member. The end portion of the structural member includes a root protrusion extending radially outward from the second surface of the structural member along a root protrusion radius to an outer end of the root protrusion to define a root protrusion height extending from the second surface of the structural member to the outer end of the root protrusion. The root protrusion further includes a root protrusion width extending between an inner edge and an outer edge of the outer end of the root protrusion. The root protrusion radius, the root protrusion height, and the root protrusion width are configured to define a stress protected weld root region isolated beyond and away from a root stress flow path propagated through the body of the structural member.

摘要： An assembly of mechanical components includes a solder joint between two metal components. A mounted component is retained on one side of a support structure by a solder joint on the other side of the support structure between a retainer and a connector that is fast with the mounted component and extends through the support structure. The retainer is of sheet metal construction, so that a height of the solder joint is no more than the thickness of the retainer, thus providing a low-profile joint.
