Establishes guidelines to prevent most forms of environmental cracking of weldments in carbon steel refinery equipment and piping. Welding processes covered by this standard include shielded metal arc welding (SMAW); gas metal arc welding (GMAW), including flux-core arc welding (FCAW); gas tungsten arc welding (GTAW); and submerged arc welding (SAW). Almost all types of weld configurations are included. The standard also addresses corrosive environments, hardness, and total stress in relation to in-service cracking of carbon steel welds.
Key words: carbon steels, cracking, hardness, hydrogen embrittlement, refinery equipment, welds.
