摘要： It is necessary to determine the effects of welding pressure in order to control the high-frequency welding process in the manufacture of pipes with longitudinal seams. It has been discovered that measurements of the height of the welding bead provide an approximation that is satisfactory for determining the mass of the bead, which is proportional to welding pressure in known pipe geometry. The height of the bead is transmitted by an optical system to the diode matrix of a commercially available diode-matrix camera. The results are processed to control welding pressure.

摘要： A system for non-destructive testing of metallic materials and for, in particular, welding seams. An ultrasonic sensor is employed and ultrasonic defect signals are producted according to the pulse echo method. The ultrasonic defect signals are digitized and the digitized signals are combined with signals corresponding to longitudinal positions along the welding seam. A defect curve is produced form the data resulting from combining the digitized signals with the signals corresponding to longitudinal positions along the welding seam. The resulting defect curve is compared with data from a catalog of classes of defects. The system eliminates the need for manual ultrasonic reinspection of presumed welding defects.

摘要： Method and apparatus for the continuous industrial production of tubular bodies in which coated or uncoated steel strip is formed to a slit tube and the opposite strip edges are longitudinally seam welded at high speed by a laser beam of high energy density under protective gas with or without supply of additive material, and after a preparation adapted to the narrow melt zone and bringing together of the strip edges a fusion welding with subsequent controlled cooling and upsetting is carried out which results in a seam geometry suitable for any further processing.
