This document provides welding procedure specifications for SMAW welding of joints with various base metals and filler metals. It specifies details such as preheat temperature range, welding positions, electrical characteristics, and techniques. Welding can be done in multiple passes on joints of any design using a direct current electrode negative polarity and weaving technique with a string or weave bead. Post weld heat treatment is not required.
