摘要： The present invention is to provide a forming method and forming stand for forming a welded pipe of high dimensional accuracy on a welded pipe manufacturing line in which a metallic strip of a predetermined width is continuously formed by rolls and then welded, and more particularly the present invention is to provide a forming method and forming stand for forming both edge portions of the metallic strip with high accuracy. Positions of two pairs of upper and lower horizontal forming rolls or two upper horizontal forming rolls, the rolls being provided when the upper and lower horizontal rolls are divided into two with respect to the width direction of the metallic strip, can be adjusted in the width direction, and each divided upper roll can be turned and fixed on a vertical axis. Further, in order to exhibit the effect of the present invention at the maximum, the turning direction and turning angle of each upper roll is limited. When the forming stand is constructed in the above manner, the edges of the metallic strip can be appropriately formed without deteriorating the accuracy of wall thickness of the metallic strip to be formed, and further the roll can be shared when metallic strips of different pipe diameters are formed.

摘要： A hollow precision-machined body, such as a circular waveguide for transmission of millimeter wavelengths, is welded to a metallic body with minimum distortion of the precision body, by directing a concentrated beam of heat-producing energy such as an electron beam or a laser beam or a plasma across and peripherally about the interface between the precision and metallic bodies to produce a bead whose width at the contact area is related to the clearance between the bead and the inner surface of the precision tube and the maximum allowable strain at the inner face of the precision tube. Alternately, the energy beam is directed along the interface and around the periphery thereof to produce a bead whose depth of penetration is related to the thickness of the precision body and the maximum permissible strain at the inner surface of the precision body.
