White River Bridge – Arkansas
7/8 x 6 3/16 Headed Shear Connectors to Bridge Girders. This job called for roughly 4,500 ea 7/8 x 6 3/16 HSC’s. Our customer supplied the studs for this job and kept them in a conex underneath the bridge. The White River Flooded, and so did the conex with our studs inside. The customer had a team of guys that had to grind the rust off the head of the studs so they wouldn’t ruin our headed chucks. It helped, but we still burned though more chucks than we’d have liked. A rusty head on a stud scratches the inside of the chuck. This eventually causes the stud to arc against the chuck, and at 1900 amps, the chuck is toast. Lesson: Always let Stud Welding & Fasteners, Inc. provide the studs for any job Elrod Stud Welding is going to shoot for you. We’ll make sure they stay dry, our prices are probably less than what you’ll pay elsewhere, and in most cases we’ll bill you for the studs once we shoot them, which allows you to hold your money longer.
