A Practical Manual of Autogenous Welding (Oxy-Acetylene)

Abstract

AUTOGENOUS welding consists in uniting metals by fusion without the intervention of solder. Ordinary welds may be effected by heating in a forge, but the local application of heat by an electric current or by the heat of an intense flame is more properly called autogenous welding in contradistinction to the junction of metals made by solder. The work before us treats of welding as done by the oxy-hydrogen and oxy-acetylene blowpipe, the introductory matter on soldering and electric welding being outside the main purpose of the work. The oxy-hydrogen weld was used before oxy-acetylene, but the latter is now the most common. Acetylene burnt with an equal volume of oxygen gives a temperature which is 1000° C. higher than the oxy-hydrogen flame. For successful welding minute attention to the details of construction of the blowpipes is necessary, and the author describes the forms of blowpipes used and the generators for producing acetylene economically.
