Abstract

502,547. Making tubes. HOMBURGER EISENWERK AKT.-GES. VORM. GEP. STUMM. June 11, 1937, No. 16301. Void. Convention date, June 26, 1936. [Classes 83 (ii) and 83 (iv)] Welding ; uniting by fusion.-Welded tubes are made by shaping a metal strip a by rolls b into a slotted tube c, then preheating by burners d supplied with cheap gas such as producer gas, coke-oven gas, or coal gas, preferably with the addition of air or oxygen, and the welding either by an autogenous burner e or by welding electrodes. The tube then passes through guide or straightening rolls f.
