Use WeldOffice mobile app for reliable determination of compliance with welding codes & standards. The app comes with multi-code search features including material classifications for base metals and filler metals, definitions of welding and brazing terms, interpretations, as well as requirements identification based on test type, applicability of welding process and the type of variable. This single WeldOffice mobile app integrates previous individually published P Numbers, M Numbers and F Numbers apps with exclusive access apps addressing multi-code welding requirements. The app includes comprehensive UNS search tool. Multi-code searches include the following Standards Developing Organizations (SDOs): ASME, AWS, API, ISO.... AA, AAR, ABS, ACI, AISI, AMS, AS, AS/NZS, ASTM, CSA, DIN, EN, FED, GB, IRAM, IS, JIS, MIL, MSS, NACE, SAE. 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).
