AWS A5.18

The American Welding Society (AWS) announces the availability of AWS A5.18/A5.18M:2005,   Specification for Carbon Steel Electrodes and Rods for Gas Shielded Arc Welding.   This specification prescribes the requirements for classification of solid carbon steel electrodes and rods, composite stranded carbon steel electrodes, and composite metal cored carbon steel electrodes for gas shielded arc welding. 

Classification is based on chemical composition of the electrode for solid electrodes and rods, chemical composition of weld metal for composite stranded and composite metal cored electrodes and the as–welded mechanical properties of the weld metal for each.  Additional requirements are included for manufacture, sizes, lengths, and packaging. 

A guide is appended to the specification as a source of information concerning the classification system employed and the intended use of the electrodes and rods.

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 independently of the other.

AWS A5.29

The Specification for Low-Alloy Steel Electrodes for Flux Cored Arc Welding, AWS A5.29/A5.29M:2005, is currently available, according to the American Welding Society (AWS).  This specification prescribes the requirements for classification of low-alloy steel electrodes for flux cored arc welding.  The requirements include chemical composition and mechanical properties of the weld metal and certain usability characteristics.  Optional, supplemental designators are also included for improved toughness and diffusible hydrogen.  Additional requirements are included for standard sizes, marking, manufacturing, and packaging.  A guide is appended to the specification as a source of information concerning the classification system employed and the intended use of low-alloy steel flux cored electrodes.

AWS C3.8

The AWS recently released AWS C3.8M/C3.8:2005, Specification for the Ultrasonic Examination of Brazed Joints.  This specification presents minimum fabrication, equipment, and process procedure requirements for the ultrasonic examination of brazed joints.  Its purpose is to standardize brazed-joint ultrasonic examination requirements for all applications in which brazed joints of assured quality are required.  It provides minimum requirements for equipment, procedures, and the documentation of such tests.

AWS D14.4

The American Welding Society also announces the availability of AWS D14.4/D14.4M:2005, Specification for Welded Joints in Machinery and Equipment.  This specification establishes common acceptance criteria for classifying and applying carbon and low-alloy steel welded joints used in the manufacture of machines and equipment.  It also covers weld joint design, workmanship quality control requirements and procedures, welding operator and welding procedure qualification, weld joint inspection (visual, radiographic,, ultrasonic, magnetic particle, liquid penetrant), repair of weld defects, and heat treatment.

AWS D18.3

The Specification for Welding of Tanks, Vessels, and Other Equipment in Sanitary (Hygienic) Applications, an American National Standard AWS D18.3/D18.3M:2005, has been released by the AWS.  This specification covers the requirements for welding of carbon steels, stainless steels, and nickel alloys in sheet, plate, bar, and other forms for the fabrication and construction of new tanks, vessels, and other equipment in sanitary (hygienic) applications.  The welding of pipe or tubing to a tank, vessel, or other piece of sanitary equipment for use as a nozzle or other opening is included in this specification.  This document excludes the welding of tube and pipe for the transportation of sanitary (hygienic) system products and cleaning or sanitizing solutions. 

The American Welding Society is the largest organization in the world dedicated to advancing the science, technology, and application of welding and allied processes, including joining, brazing, soldering, cutting, and thermal spraying. Headquartered in Miami, Florida, USA, AWS serves almost 50,000 members in the United States and around the world.
