INTEGRATED APPS
- P-Numbers and M-Numbers apps provide quick lookup of base metal weldability grouping numbers for welding procedure and performance qualification. Data is provided by C-spec from the master source used for generation, proof-reading and maintenance of ASME Section IX Table QW/QB-422, AWS B2.1 Table C1 and C2, and ISO/TR 20173.
- F-Numbers app provides quick lookup of filler metal groupings for welding procedure and performance qualification. Lookup includes classifications with respective descriptions of intended use. Data is provided by C-spec. F-numbers and A-numbers assignments are based on ASME Section IX Table QW-432 and QW-442, ASME Section II Part C, AWS B2.1 Table B1 and B2, and AWS A5.1 through AWS A5.36.
- A-Numbers app calculator determines the A-Number and the type of weld deposit per ASME Section IX Table QW-442.
- UNS app searches materials classified in the SAE Unified Numbering System.
- ISO 15608 app searches base metals in ISO/TR 20172, ISO/TR 20173 and ISO/TR 20174.
- AWS D1.1 Base metals app searches base metals permitted for use with the AWS D1.1 Structural Steel Code.
- Term Definitions app compares API, ASME, AWS and ISO published definitions of welding and brazing terms.
- Interpretations app searches API, ASME and AWS published interpretations.
- Turbo Code app identifies ASME Section IX code requirements based on applicability of test type, welding process and type of variable (essential, supplementary essential and nonessential).
