Welder Testing and Certification
The requirements to perform qualification testing and supporting certified documentation for welders is a widely misunderstood concept. Various individual codes and standards that are referenced by local/jurisdictional laws will often require performance testing as will industry-specific codes and standards. Additionally, your company or organization may have internal requirements related to the process that is a basis for maintaining a quality product. Regardless of the reason, we as SVAM-CoE are here to help.

In many cases, the need to perform qualification testing for welders is driven by local or state regulations. One such case is when welding on structural steel for buildings. Virginia has adopted the “International Building Code” as law for building constructed from steel. This code contains rules in Chapter 22 which in turn references AISC 360. AISC 360 requires all welding to be performed in accordance with AWS D1.1. AWS D1.1 requires ALL welding to be performed by welders who have completed welder performance qualification tests in accordance with the rules contained in AWS D1.1.
If you or your organization have any questions about welder performance qualification testing, please contact us.
In many cases, aluminum is the material of choice for the manufacture and erection of metal structures. The American Welding Society has published the AWS D1.2 Structural Welding Code-Aluminum to address the requirements needed to assure weld quality is maintained while building or erecting aluminum structures.
SVAM-Coe can assist your organization with welder performance qualification testing in accordance with AWS D1.2. Please contact us if you need any information.
NOTE: Because of the wide variety of aluminum types and welding methods, please understand that a consultation is needed prior to scheduling any aluminum testing.
The American Welding Society D1.3-Structural Welding Code-Sheet Steel This code covers the requirements associated with welding sheet steel having a minimum specified yield point no greater than 80 ksi [550 MPa]. The code requirements cover any welded joint made from the commonly used structural quality low-carbon hot rolled and cold rolled sheet and strip steel with or without zinc coating (galvanized).
We can provide welder testing and qualification in accordance with D1.3 or the AWS QC-7 Supplement C for sheet metal.
Please let us know if you need any additional information.
AWS D1.5 covers the welding requirements for AASHTO welded highway bridges made from carbon and low-alloy
constructional steels. For performance qualification, no power tools are allowed during testing. We can perform SMAW performance qualification testing using our WPS’s, however, it is suggested that contractors provide there own WPS’s for performance qualification testing in the scope of AWS D1.5.
Additionally, the engineer may or may not accept testing performed by an outside organization…or they may require it. In Virginia, the Virginia DOT follows the requirements of AWS D1.5 verbatim for performance qualification testing.

AWS D1.6 covers the requirements for welding stainless steel structural assemblies. We can assist your organization with the qualification of welders in accordance with AWS D1.6.
API 1104 This standard covers the gas and arc welding of butt, fillet, and socket welds in carbon and low -alloy steel piping used in
the compression, pumping, and transmission of crude petroleum, petroleum products, fuel gases, carbon dioxide, and nitrogen and, where applicable, covers welding on distribution systems. It applies to both new construction and in-service welding.The welding may be done by a shielded metal-arc welding, submerged arc welding, gas tungsten-arc welding, gas metal-arc welding, flux-cored arc welding, plasma arc welding, oxyacetylene welding, or flash butt welding process or by a combination of these processes using a manual, semi-automatic, or automatic welding technique or a combination of these techniques. The welds may be produced by position or roll welding or by a combination of position and roll welding.
The ASME Boiler and Pressure Vessel Code Sec. IX is referenced for all ASME Boiler and Pressure vessel codes for boilers, pressure vessels, and piping. This code typically requires the manufacturer or contractor to observe all testing. Some exceptions are allowed. If you need assistance qualifying your welders in accordance with Sec. IX, Please contact us and we can go over the process with you.
