A Production Engineering Study of Iron-Powder or Contact Electrodes for Manual-Arc Welding Operations.
Abstract
To review, analyze, and summarize assorted commercial and technical information related to the operation, performance, economic aspects, and application of iron-powder or contact electrodes utilized in the manual-arc, weld-fabrication of mild-and low-alloy steels. The degree of commercial acceptance hitherto achieved entitles iron-powder or contact electrodes universal recognition as an additional valuable tool available for manual-arc welding operations. The major advantage to be gained from the use of contact electrodes is in reduction of labor costs through inherently faster welding speeds. In applications where replacement of conventional electrodes with equivalent sizes of the contact types is tolerable, savings ranging from 10-55 per cent may be anticipated. However, in applications where joint design and welding position can impose restrictions of size and grade upon the contact types, utilization of larger sizes of the conventional types may serve to reduce; and in some cases, even nullify the greater economic potential of the former.
