Abstract

677,868. Making tubes; welding by pressure. ETNA MACHINE CO. Oct. 3, 1950, No. 24175/50. Classes 83 (ii) and 83 (iv). A welding machine for producing longitudinally-jointed tubes formed from flat strip comprises a series of rolls on a bed, a transformer in a frame at the rear of the rolls, from which extends a rotatable shaft transverse to the rolls and carrying on the free end thereof a pair of electrode rollers which engage a tube in the rolls and means in front of the electrodes to adjust the position of the frame in a guideway on the bed and hence the axial position of the electrodes relative to the tube. In an embodiment a rotatable transformer 15 carrying electrodes 13 on a shaft 14 is mounted in a housing 16 vertically slidable on columns 17 which form a frame with a base 18 and a top 19. A motor 20 on the top 19 effects vertical movement of the housing 16 through gearing 24, 25, 26 and a rod 27 attached to the housing 16. The base 18 is grooved at 28 to receive guidebars 29 while a block 33 secured to the base 18 and movable in a slot 32 in the bed 10 engages a screwed rod 35 having a handle 41. Turning the handle 41 slides the frame across the bed 10. A key 31 engages a keyway in the base 18 and an electrode dressing device is provided on the housing 16.
