Army Hospital – Ft. Campbell, KY
¾ x 4 7/8 Headed Shear Connector shot thru-deck and multiple sizes of Deformed Bar Anchors (DBA). Weather was a huge obstacle in completing this project. The flutes were filled with ice and snow and it took a large effort to prepare the deck for studs. Another problem was the multiple odd length DBA that were supplied by the fabricator, and it was left in the weather and became scaled with rust. This made for a very difficult installation because our chucks would arc out often and when they did shoot, they wouldn’t properly arc due to the weld end being rusty. We went through many chucks and lots of scrap DBA to finish this one out.
Of course, Elrod Stud Welding approaches every job like it will be 100% inspected. So, we did our due diligence to ensure we left a quality product. Finally, since the fabricator supplied the studs, they too because rusty. Many of them couldn’t be used. In addition, the fabricator ordered way too many studs for the job. And they were left with about 3000 ea ¾ x 4 7/8 HSC’s that were ruined by the weather. If the fabricator would have ordered the studs from Stud Welding & Fasteners, sister company to Elrod Stud Welding, the fabricator would have only been charged for the studs used on the job.
