The American Welding Society (AWS) is a not for profit organization dedicated to the advancement of welding technology and practices. The organization is headquartered in Miami, Florida (strangely enough) and has some 73,000 members worldwide.

The welding standards as dictated by the AWS are some of the most widely followed. When AWS code is specified in a contract for a job, these regulations become mandatory. Below is a sampling of the most relevant portions of the AWS code for structural welding that regularly impacts professionals. Other sections of the code refer to inspection and various methodologies, among other topics.

  • D1.1
    • Regulations for the erection and fabrication of welded steel Structures, where the material used is greater than ⅛ inches, or 3.2 millimeters thick.
  • D1.2
    • Code for structural welding code aluminum. Generally good for fabrication of appurtenances and support structures.
  • D1.3
    • For arc welding of structural support steel.
  • D1.4
    • On welding reinforcing steel.
  • D1.5
    • The section relevant for bridge welding.
