    摘要： A welding process and an apparatus used therein for providing a significant improvement in the detrimental tensile residual stress condition on the root side of welds, especially on the inside wall of piping welds. The method combines an extremely thin weld joint design with a non-circular cylindrical, thin welding electrode having an elongated cross-sectional shape. During welding, the elongated dimension is aligned parallel with the length of the weld joint. This combination enables joining of piping and other residual stress-sensitive components with both the initial weld joint preparation and the completed weld having a uniquely thin width and with a high aspect ratio of depth to width. Use of this high-aspect-ratio weld joint process substantially mitigates welding-induced residual stresses, without the normally required internal water cooling. The process is considered to be effective in mitigating residual stresses and the associated welding strains (distortion) in joints having any path shape, whether welded from one or more sides of the material.

    摘要： An apparatus for machining a weld tab on an article. In one embodiment, the apparatus includes: a base member including at least one rolling element for contacting an underlying surface, the base member having a leading end and a trailing end; a cutting apparatus operably connected to the base member, the cutting apparatus including: a cutting member positioned proximate the leading end of the base member, the cutting member sized to coincide with a size of the weld tab; and a handle member proximate the trailing end and operably connected to the cutting member, the handle member for modifying a position of the cutting member relative to the base member.
