Patent ID: 6870119

Claim:
A method of rapidly welding rebar sections using gas metal arc welding (GMAW) to obtain a fusion weld joint, comprising: shearing the rebar sections into lengths appropriate for a construction application; bending the sheared rebar into shapes appropriate for the construction application; placing the rebar sections into a welding jig; positioning the rebar sections to physically touch and intersect at a desired location; adjusting an electrical power source of the welder within a range of approximately 100 to 185 kilowatts; positioning a welding rod at a rebar intersection point; positioning a filler material at the weld location; delivering a shielding gas to the weld location; applying electrical power to a welding electrode wire using an electrical power delivery system; and arcing said electrode wire at the intersection point to form a fusion weld joint having a flare bevel groove.
