3 Elements
of Submerged Arc Welding Four
elements are present in the making of a submerged arc weld:
1. Heat generated by
the passage of an electric current through an arc. 2. Welding
wire of consumable bare metal. 3. The
pieces which are to be welded. 4. Submerged
Arc Flux - a granulated mineral welding composition. 5. A
fifth element, present in making all except mold and plug welds, is
relative motion between the welding
head and the work. General
Sequence of Operations Reducing
submerged arc welding to its simplest terms, with one frequently
used equipment assembly, the general sequence of operations
in making a submerged arc weld is as follows: 1.
Setting Up the Welding Equipment (Simple Portable Installation).
a) The Submerged Arc
Welding Head is assembled in accordance with
the instructions supplied. b) The
head, control, and wire reel are mounted on the self- propelled
carriage. Continued
