摘要： A tube is formed from a polycrystalline silicon carbide having a density of from 3.18 to 3.21 g/cm.sup.3, a maximum impurity content of 20 ppm, and imperviousness to fluids by a process which comprises precipitating the silicon carbide on the surface of a rod-shaped graphite structure by a chemical vapor-phase synthesis method and thereafter removing the graphite structure. A water-jet nozzle of high resistance to abrasive wear can be produced by using this tube as an inner tube thereof to form the flow path for a water jet to be ejected therethrough.

摘要： An apparatus for continuous production of seam-welded steel tubing is proposed. The apparatus includes a series of shaping rolls for shaping a strip taken out from a strip coil into a tubular intermediate product, the roll series including a finpass roll group. The tubular product is subjected to seam welding under the action of a seam welder. Before arrival at the welder, a substantial main part of the preformed tubing with exception of opposing edge zones thereof is subjected to heating by a heater compensate for excess compressive stresses induced in the edge zones, while these zones are subjected to cooling by a cooler for avoiding otherwise formation of disadvantageous edge wavings which would otherwise occur.

摘要： A process of continuous production of seam-welded steel tubing is concerned.A steel strip is taken out from a strip coil and conveyed to a tube-preshaping step including a plural of shaping roll stand positions. In the preshaping step, the strip is laterally rounded up gradually from band strip to a rough-shaped tubing until the side edges are brought into a mutually abutting state ready for seam-welding. The preshaping step is divided into a plurality of local regions. In these local regions, substantially body portion with exception of corresponding marginal edge zones of the tubing stock is separately subjected to heating. The heating width and heating intensity at these regions are increased stepwise as the tubular stock advances from upstream to downstream for avoiding conventionally appearing edge wavings and buckling undulations in the material of the steel tubing.

摘要： A radiographic test is conducted on a welded portion of a pipe or the like to form a radiographic image, which is introduced into a computer. Volumetric defects and planar defects in the radiographic image are emphasized and extracted by separate methods to obtain a volumetric candidate defect image and a planar candidate defect image. The candidate defect images are then combined to form a single image in which defects can be easily identified. Features of defects in the images are measured, and a set of interference rules is applied to the measured features. Each inference rule gives a degree of certainty that a defect is of a certain type. The degrees of certainty determined by a plurality of the rules are collated to obtain a total degree of certainty, and the type of a defect is inferred from the total degree of certainty.

摘要： In the manufacture of welded pipes, edge buckling or waving of the strip is prevented by heating. In one method, during the process for bending the strip into a tubular form, the edges of the strip are heated so that tensile stress exerted thereon is reduced to a minimum and, thereafter, before the edges are abutted against each other, the strip is wholly heated so that the compressive stress exerted on the edges is reduced to a minimum. According to another mode, during the process for bending the strip gradually into a tubular form or during the process in which the edges of the strip are held in abutment against each other, the strip except its portions of the edges is substantially or partially heated so that the strip except its portions of the edges is subjected to compressive stress while the portions of the edges are subjected to tensile stress, and under these conditions the edges are welded together.

摘要： A nozzle for gas shielded arc welding having a support ring to be mounted on a welding torch, a cylindrical nozzle member to be mounted on the support ring and a holddown ring for securing the nozzle member to the support ring. The nozzle member is formed of a heat-resistant non-conductive material so that spatters seldom adhere to the nozzle member. The nozzle member is fixed by being pressed against the support ring, which structure facilitates the manufacture of the nozzle member. This is useful especially as a nozzle for CO.sub.2 arc welding.
