Abstract
The method of fabricating low-cast, high-yield strength weld wire for welding includes displacing the weld wire through a rotary straightener having a pair of dies rotatable in opposite directions. Each die has a slider for introducing a bend in the wire as the wire is fed through entry and exit openings of the die. By rotating the dies in opposite rotational directions with bends introduced in the wire in the dies, the wire is cold work-hardened. The wire exiting the dies is wound on a spool. The weld wire when unwound from the spool has a low-cast and a high-yield strength.
