Learn why MIG, pulsed MIG, TIG and pulsed TIG are the ideal choices when welding sheet metal. When welding thin metal, the main objective is to avoid warping, burn-through and excessive heat-affected zones while still ensuring the weld has enough mechanical strength for the application.

The "adjacent box beam system" is typically more than 21 inches deep. The beams are normally three feet or four feet wide; however, some states have used wider sections. Figure 2.2.3-2 shows cross sections of common butted precast prestressed beams. In this study, the live-load moment-distribution factors (LLMDFs) were evaluated for an adjacent precast prestressed concrete box beam bridge. The bridge used a new shear key configuration, which was grouted with ultrahigh performance concrete (UHPC) and contained noncontact lap-splice dowel bars.
