Abstract
22,078. Dollman, H. Sept. 28. [Addition to 14,555/09.] Welding; piling.-A modification of the process of making tubes from two hollow blooms described in the parent Specification consists of sand-blasting or pickling the edges of the blooms to remove the scale instead of machining, and then primarily welding the edges at the ends together and completing the weld in a furnace. To keep the blooms in position for welding, they may be prepared from one length A', A<2> by sawing nearly through the metal at 1 and then bending the part A<2> on to the part A<1> and primarily welding the edges 4, 5 together before completion in a furnace as before.
