Lesson 10 - Reliability of Welding Filler Metals

© COPYRIGHT 2000 THE ESAB GROUP, INC. LESSON X 10.3 THE AMERICAN WELDING SOCIETY (AWS) The AWS publishes a number of specifications, standards and codes that have been adopted by many governing bodies and industries. The AWS may be considered to be the basic source of welding and welding engineering information in the USA. Many other codes and specifications will include or refer to various AWS Filler Metal Specifications. Electrode and welding filler metal manufacturers assign the appropriate AWS Classification to their products wherever possible, as a means of standardization, according to the AWS Filler Metal Specifications. The specifications prescribe the classification requirements including such items such as chemical composition of the weld metal, radiographic (X-ray) soundness tests, weld metal tension tests, impact tests, bend tests, and fillet weld tests where applicable. The following is a complete list of the AWS Filler Metal Specifications for ferrous and non-ferrous materials. 10.3.1 AWS Filler Metal Specifications Specification No. Description A5.1-91 Carbon Steel Covered Arc Welding Electrodes A5.2-92 Iron & Steel Oxy Fuel Gas Welding Rods A5.3-91 Aluminum & Aluminum Alloy Covered Electrodes A5.4-92 Corrosion Resisting Chromium & Chromium-Nickel Steel Covered Electrodes A5.5-96 Low Alloy Steel Covered Arc Welding Electrodes A5.6-84 Copper & Copper-Alloy Covered Electrodes A5.7-84 Copper & Copper-Alloy Bare Welding Rods & Electrodes A5.8-92 Brazing Filler Metals A5.9-93 Corrosion-Resisting Chromium & Chromium-Nickel Steel Bare & Composite Metal Cored & Stranded Electrodes & Welding Rods A5.10-92 Aluminum & Aluminum Alloy Bare Welding Rods & Electrodes A5.11-90 Nickel & Nickel Alloy Covered Welding Electrodes A5.12-92 Tungsten Arc Welding Electrodes A5.13-80 Solid Surfacing Welding Rods & Electrodes A5.14-89 Nickel & Nickel-Alloy Bare Welding Rods & Electrodes A5.15-90 Welding Rods & Covered Electrodes for Welding Cast Iron A5.16-90 Titanium & Titanium Bare Welding Rods & Electrodes
