Abstract

1321444 Making tubes; welding by pressure VEREINIGTE OSTERREICHISCHE EISENUND STAHLWERKE AG 2 Sept 1970 [8 Sept 1969] 42085/70 Headings B3A and B3R Two strip-shaping rolling machines 7, 8 and associated welding heads 33, 34 produce in one arrangement, Fig. 1, two one-seam tubes 16, 11 from two strips 5, 6 running through side by side and in a second arrangement, Fig. 3, one twoseam tube from two strips 20, 21 running through one above the other or one single seam tube. The strips are butt welded using high frequency current conductively or inductively supplied to the strips. The rolling machines 7, 8 are displaceable vertically by means of a removable floating plate 9; the shaping rolls 12, 15; 12<SP>1</SP>, 15<SP>1</SP> of each machine are displaceable horizontally along their shafts and the high frequency welding heads 33, 34 are suspended so as to be displaceable in longitudinal and transverse directions. After welding, the tube(s) are cooled at 39 and then fed through calibrating machines 40, 41. Means such as flying shears or saws are used to cut the tubes to length. Two one-seam tubes of round, flat, oval, square, rectangular or hexagonal cross-section may be produced simultaneously, or one two-seam tube of round or rectangular cross-section and with e.g. 8 fold flanges may be produced.
