AWS A4.5M/A4.5: 2020 (ISO 15792-3:2011 MOD) STANDARD METHODS FOR CLASSIFICATION TESTING OF POSITIONAL CAPACITY AND ROOT PENETRATION OF WELDING CONSUMABLES IN A FILLET WELD
This standard describes preparation and assessment of a fillet weld test piece. Test conditions prescribed and results required should not be considered to be requirements or expectations for a procedure qualification. This specification makes use of both U.S. Customary Units and the International System of Units (SI). Since these are not equivalent, each system must be used

This document establishes standard procedures for determination of moisture content of welding fluxes and welding electrode coverings. The test involves combustion of a sample in an oxygen carrier gas at elevated temperature. Any water evolved from the sample or formed by the combustion process is measured by means of either Karl Fischer titration or infrared detection. The key differences between these methods and traditional thermo gravimetric techniques are the inclusion of instrument calibration procedures, system verification checks and use of more accurate analytical techniques for water detection.

AWS A4.2M:2020 (ISO 8249:2018 MOD) STANDARD PROCEDURES FOR CALIBRATING MAGNETIC INSTRUMENTS TO MEASURE THE DELTA FERRITE CONTENT OF AUSTENITIC AND DUPLEX FERRITIC-AUSTENITIC STAINLESS STEEL WELD METAL
Calibration procedures are specified for a number of commercial instruments that can then provide reproducible measurements of the ferrite content of austenitic stainless steel weld metals. Certain of these instruments can be further calibrated for measurements of the ferrite content of duplex ferritic-austenitic stainless steel weld metals. Calibration with primary standards (non-magnetic coating thickness standards from the U.S. National Institute of Standards and Technology) is the preferred method for appropriate instruments. Alternatively, these and other instruments can be calibrated with weld-metal-like secondary standards. Reproducibility of measurement after calibration is specified. Problems associated with accurate determination of ferrite content are described.

AWSA3.0M/A3.0:2020 STANDARD WELDING TERMS AND DEFINITIONS; INCLUDING TERMS FOR ADHESIVE BONDING, BRAZING, SOLDERING, THERMAL CUTTING, AND THERMAL SPRAYING
This standard is a glossary of the technical terms used in the welding industry. Its purpose is to establish standard terms to aid in the communication of information related to welding and allied processes. Since it is intended to be a comprehensive compilation of welding terminology, nonstandard terms used in the welding industry are also included. All terms are either standard or nonstandard. They are arranged in word-by-word alphabetical sequence.

This metric practice guide is based on the International System of Units (SI) as defined in the U.S. Federal Register notice of July 28, 1998, “Metric System of Measurement: Interpretation of the International System of Units for the United States.” It includes the base units, derived units, and rules for their use. Also covered are conversion factors and rules for their use in converting U.S. customary units to SI units. Recommendations are presented for style and usage in such areas as prefixes, punctuation, number grouping, etc. There are also suggestions to industry for managing the transition.

This document provides methods for determination of welding heat input, both in the case of traditional welding systems and those employing waveform-controlled welding. It is intended that this specification be referenced by other qualification and fabrication welding standards requiring the measurement and calculation of heat input for maintenance of distortion and weldment properties such as strength, toughness, and corrosion-resistance.
