AWS A5.16/A5.16M:2013

This specification prescribes the requirements for the classification of over 30 titanium and titanium-alloy welding electrodes and rods. Classification is based upon the chemical composition of the electrode. Major topics include general requirements, testing, packaging, and application guidelines.
Scope : 1.1 Scope. This standard specifies requirements for the classification of solid wire electrodes, solid wires and rods for fusion welding of titanium and titanium-alloys. The classification of the solid wires and cut lengths and spools of wire is based on their chemical composition. For titanium welding consumables, the compositions of the wire electrodes for the gas metal arc welding (GMAW)process are the same as for the gas tungsten arc welding (GTAW) process, the plasma arc welding (PAW) process, the laser beam welding (LBW) process, and other fusion welding processes. Therefore, the use of the word â??wires/rodsâ? in this classification refers to both â??wire electrodesâ? and â??wires and rodsâ? in this standard. NOTE: In this standard, the word â??titaniumâ? is used for â??titanium and titanium-alloys. â??The classification of titanium wires/rods is based upon the chemical composition of the wires/rods. 1.2 Units of Measure. This standard makes use of both U.S. Customary Units and the International System of Units (SI). The latter are shown within brackets ([ ]) or in appropriate columns in tables and figures. The measurements may not be exact equivalents; therefore, each system must be used independently when referring to material properties. Standard dimensions based on either system may be used for sizing of electrodes or packaging or both under A5.16 or A5.16M specifications. 1.3 Safety. Safety and health issues and concerns are beyond the scope of this standard; some safety and health information is provided, but such issues are not fully addressed herein. American Welding Society: (1) ANSI Z49.1. Safety in Welding, Cutting, and Allied Processes (2) AWS Safety and Health Fact Sheets (3) Other safety and health information on the AWS website Material or Equipment Manufacturers: (1) Material Safety Data Sheets supplied by materials manufacturers (2) Operating Manuals supplied by equipment manufacturers Applicable Regulatory Agencies Work performed in accordance with this standard may involve the use of materials that have been deemed hazardous, and may involve operations or equipment that may cause injury or death. This standard does not purport to address all safety and health risks that may be encountered. The user of this standard should establish an appropriate safety program to address such risks as well as to meet applicable regulatory requirements. ANSI Z49.1 should be considered when developing the safety program.
