12. A welding procedure is being qualified using ASTM A709 Grade 100W Type E Plate. The thickness is 1-1/2" and the welding is done in the 2G welding position using SMAW process. Assume all requirements are successfully met. For what ranges of diameters will this qualification be valid? a. up to 4" diameters b. 4" to 10" diameters only c. 8 Preheat and Interpass Temperature for - WELDING When the base metal temperature is below 32°F [0°C], the base metal shall be preheated to a minimum of 70°F [20°C] and the minimum interpass temperature shall be maintained during welding. For ASTM A709 Grade HPS 70W and ASTM A852, the maximum preheat and interpass temperatures shall not exceed 400°F [200°C] for thicknesses up to 1-1/2 in Steel Construction in the New Millenniumsighted designers were advocating welding, and fabricators recognized the advantage of using fewer materials with a method that would gain 100 percent elastic continuity. This, coupled with the development of the Structural Welding Code by AWS, led to the demise of riveting and the development of the all-welded joint. Riveting, A Lost Art

Welding procedures must be selected that are suitable for the steel being welded and its intended use. Note the emphasis on use of proper procedures. ASTM Standard Specification A709/A709M, Section 1.3, states, When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade Welding metals of dissimilar strengths - The FABRICATORCertain joint designs may allow you to undermatch the filler metals strength to the lower-strength material. For instance, some fillet joints created by joining a 100-KSI yield, quench-and-tempered material like A514 to an even higher-strength, proprietary high-strength, low-alloy 130 material can accommodate welds with 70-KSI filler metals. a709 grade 50 steel gauge, astm a519 grade 1020 supplier A709 Structural, Carbon & HSLA Steel Plate Chapel SteelChapel Steel stocks A709 Grade 36, A709 Grade 50 and A709 Grade 50W.
