1AWS Fundamental Terms and Definitions Learning to talk like a welder
2IntroductionFundamental terms and definitions used in the welding fieldCommunicate effectively with Supervisors, Engineers, Inspectors, your co-workers and ……your Welding Instructor. Need to know for Printreading for WeldersDemonstrating the knowledge and ability to communicate welding information in a professional manner may enhance your potential for career advancement.
3Define - “Welding”A joining process that produces coalescence of materials by heating them to the welding temperature, with or without the application of pressure or by the application of pressure alone, and with or without the use of filler metal
5Advantages: Joins all commercial metals Most common method for joining 2 or more metals to make them act as one pieceAllows the production of a monolithic structure that is strong in all directionsIs the lowest cost, permanent joining method.Affords lighter weight through better use of materialsCan be used anywhereProvides design flexibility
25Parts of groove welds Root opening – space between base metal Root face or “land” – flat spot used to control penetrationGroove or Bevel face – where weld interface occursBevel angle – degrees of bevelGroove angle or Included Angle – total of bevel angles
27Parts of fillet welds Legs – used to specify weld size Face – side from which welding is doneRoot – opposite the face – weakest pointToe – where face intersects the base metalThroat – gives the weld strength
29Welder Qualification “Certification” Part of a Quality Assurance System designed to insure as much as possible that welds of sufficient quality are being producedThere is no certification that qualifies a welder for all types of workSpecific to process, metal, position, progression, etc“Certified” welder has a document certifying that he or she produced a weld that met a specific standard or code.
30Process Select a code (AWS, ANSI, API, CWB, etc) Write a Welding Procedure Specification (WPS)Qualify the WPSQualify the welder (welder performance qualification test)Issue documentation
