  • Welding Technology a Suncam Continuing Education Course
    033.pdf Welding Technology A SunCam Continuing Education Course Welding Technology By Roger Cantrell www.SunCam.com Page 1 of 35 033.pdf Welding Technology A SunCam Continuing Education Course Learning Objectives This course introduces the student to the concept of developing procedures for welding and brazing. Welding and brazing variables are introduced and some example concepts for applying each variable are highlighted to pique the student’s interest and perhaps lead to further study. Upon completion of this course, the student should be able to: • Understand the concept of creating a welding/brazing procedure • Identify several commonly used welding/brazing processes • Identify the more common welding/brazing variables • Appreciate some of the considerations for applying each variable 1.0 INTRODUCTION This course highlights the basic concepts of developing a welding or brazing procedure specification (WPS/BPS). There are a number of ways to approach this subject such as by process, base material, etc. It will be convenient to organize our thoughts in the format of ASME Section IX. The various factors that might influence weld quality are identified in ASME Section IX as "Welding Variables". "Brazing Variables" are treated in a separate part of Section IX in a manner similar to welding variables. The listing of variables for welding procedures can be found in ASME Section IX, Tables QW-252 through QW-265 (a table for each process). The layout of each table is similar to Figure No. 1. www.SunCam.com Page 2 of 35 033.pdf Welding Technology A SunCam Continuing Education Course Process Variable Variation (Description) Essential Supplementary Essential Nonessential Joint Backing X Root Spacing X Base P Number X Metal G Number X Filler F Number X Metal A Number X Continued in this fashion until all relevant variables for the subject process are listed.

  • Welding Operations
    WELDING OPERATIONS Date Initiated: February 1, 1993 Dates Modified / Updated: September 15, 1993 October 16, 1998 PROCESS DESCRIPTION: Many industrial and manufacturing facilities regularly use a variety of welding processes and materials. The processes include; - Gas Metal Arc Welding (GMAW) - a. k. a. Metal Inert Gas Welding (MIG), - Gas Tungsten Arc Welding (GTAW) - a. k. a. Tungsten Inert Gas Welding (TIG), - Shielded Metal Arc Welding (SMAW) - a. k. a. Manual Metal Arc Welding (MMA), - Flux Core Arc Welding (FCAW), - Submerged Arc Welding (SAW), - Arc Spot Welding, - Electrogas Welding, - Electrostag Welding, - Brazing, - Thermal Cutting, - Resistance Welding, - Plasma Arc Welding, - Electron Beam Welding, - Laser Beam Welding The majority of the common welding processes can be classified as either gas metal arc welding (GMAW) or shielded metal arc welding (SMAW). GMAW generally uses an electrical current to melt and apply a filler metal under a blanket of inert gas. SMAW traditionally uses an electrical current to melt specially coated electrodes which form a protective flux over the weld during application. Both processes use electrodes, filler metals, wire, coatings, and/or gases that may contain and emit several listed substances including NOx, CO, cadmium, cobalt, copper, chromium, manganese, nickel, lead, zinc, and fluorides. Welding operations release fumes and particulates with diameters of 0.001 to 100 microns. Previous studies of welding emissions have been primarily focused on worker exposure and safety. Many technical difficulties have been identified regarding proper sampling and analytical procedures due, in part, to the wide variety of processes, welding materials, and field conditions. The majority of existing test data which can be used to quantify welding emissions is based on studies performed by the American Welding Society (AWS).

  • Gas-Shielded Arc Welding TIG Welding
    Gas-Shielded Arc Welding Gas-shielded welding can be divided into the tungsten gas-shielded welding and the metal gas-shielded welding processes. The tungsten gas-shielded welding covers the processes − Tungsten plasma arc welding (PAW) − Inert-gas tungsten-arc welding (TIG), whereby TIG welding is the most widely used fusion welding process for aluminium. The plasma welding consists only of the plasma-arc welding process which works with a transferred arc. The metal shielded-gas welding is limited to the metal inert-gas welding process operating with an inert gas as shield, as well as a process combination with plasma welding (plasma metal shielded-gas welding - PMIG). The abbreviations used are: GAW Gas-shielded arc welding GMGMMA Gas-mixture shielded metal-arc welding GTAW Gas-shielded tungsten arc welding (MAGM) GMAW Gas-shielded metal arc welding MAGC CO2-shielded metal-arc welding AHW Atomic hydrogen welding NGW Narrow-gap welding CAW Constricted arc welding EGW Electro -gas welding TIG Tungsten inert-gas arc welding PMIG Plasma MIG welding MIG Metal inert-gas arc welding MAG Metal active-gas arc welding p Pulsed arc PJW Plasma jet welding sh Short arc PAW Plasma arc welding sp Spray arc PJPW Plasma jet plasma arc welding l Long arc TIG Welding Principle of TIG Welding TIG welding equipment Watercooled TIG welding torch Torch forms for TIG welding Shielding gases for welding and cutting Flow meters Flow meter for torches Effect of current and inert gas Argon consumption for TIG welding Tungsten electrodes

Department of The University of British Columbia 2075 Wesbrook Place Vancouver, Canada V6T 1W5 Date 7 ABSTRACT Previous studies of the properties of electroslag weld metal have been done using electroslag remelted ingots made under welding conditions. This procedure assumes the electrical and thermal regimes of these pro• cesses to be equivalent. To test this assumption an experimental program was devised in which the remelted metal of an ingot and weld made with each of three slag systems was analysed and the mechanical properties examined. The results show that each process imparted different properties to the remelted metal by alloy and inclusion modification. Consequently the above assumption was proved invalid. Special consideration was given to the effect of inclusion composition and overall distribution toward mechanical properties.

Brazing and Soldering: Melting of filler rod only • Brazing: higher temperature, ~brass filler, strong • Soldering: lower temp, ~tin-lead filler, weak 2.

  • Lecture: 3 Classification of Welding Processes II Apart from Technical
    Lecture: 3 Classification of Welding Processes II Apart from technical factors, welding processes can also be classified on the fundamental approaches used for deposition of materials for developing a joint. This chapter presents the classification of welding processes as welding processes and allied process used for developing a joint Keywords: Welding and allied processes, approach of classification, cast weld, resistance weld, fusion weld, solid state weld 3.1 Classification of welding processes There is another way of classifying welding and allied processes which is commonly reported in literature. Various positive processes involving addition or deposition of metal are first broadly grouped as welding process and allied welding processes as under: 1. Welding processes i. Cast weld processes ii. Fusion weld processes iii. Resistance weld processes iv. Solid state weld processes 2. Allied welding processes i. Metal depositing processes ii. Soldering iii. Brazing iv. Adhesive bonding v. Weld surfacing vi. Metal spraying This approach of classifying the welding process is primarily based on the way metallic pieces are united together during welding such as Availability and solidification of molten weld metal between components being joined are similar to that of casting: Cast weld process. Fusion of faying surfaces for developing a weld: Fusion weld process Heating of metal only to plasticize then applying pressure to forge them together: Resistance weld process Use pressure to produce a weld joint in solid state only: Solid state weld process 3.2 Cast welding process Those welding processes in which either molten weld metal is supplied from external source or melted and solidified at very low rate during solidification like castings.
