Abstract
An ergonomic method for a composite floor structure with metal decking having ribs and flat sections with openings in the flat sections over the center of the I-beams for fastening and flattening the decking on the I-beams, removing contaminates from the I-beams through the openings to form a clean welding zone and welding studs in the clean welding zones. Tools for fastening, removing contaminates and welding are carried by carts having a bottom frame with rollers and an outrigger that keeps a working end of the tool perpendicular to the composite floor structure. In operation as the carts are rolled over the metal decking the rollers contact the ribs while other rollers extend over and free from contacting the flat sections. The carts have a tool balancer to minimize the effort required of a worker to raise and lower the tool into working position from an upright position.
