WELDING PRINCIPLES AND APPLICATIONS
9TH EDITION CHAPTER 1 AND 2 REVIEW
QUESTIONS WITH CORRECT ANSWERS
QUESTIONWhat does Shielded Metal Arc Welding (SMAW) use to conduct the welding current from
the electrode holder to the work? - answer-Consumable Stick Electrode.
QUESTIONWhat is the purpose of the solid flux that covers the electrode in shielded metal arc
welding (SMAW)? - answer-It protects the weld from atmospheric conditions along with other
beneficial factors.
QUESTIONWhat protects the molten weld from atmospheric contaminations in GTAW welding? -
answer-A shielding gas flowing from the gun nozzle.
QUESTIONWhy is it important to clean all contaminations such as oxides, oil, and dirt off of the
surface of the part being welded with GTA Welding? - answer-GTAW is the cleanest process
because there is no flux, only shielding gas.
QUESTIONWhat welding process uses a solid electrode wire that is continuously fed from a spool,
through the welding assembly, and out through the gun? - answer-Gas Metal Arc Welding (GMAW).
QUESTIONWhat are the advantages of GMA welding? - answer-GMA Welding is extremely fast and
economical because it can produce long welds rapidly that require very little post weld cleanup.
QUESTIONHow is flux cored arc welding (FCAW) electrode wire different from gas metal arc
welding (GMAW) electrode wire? - answer-FCAW wired is filled with a flux core, removing the need
for shielding gas.
What type of welding uses a hammer to join heated or softened metal? - answer-Forge Welding.
QUESTIONWhat advantage does resistance welding have over forge welding? - answer-Provides a
more reliable and faster way of joining metal.
QUESTIONWhat term describes the fusion or growing together of the grain structure of materials
being welded? - answer-Coalescence.
QUESTIONWelding is defined as a joining process that produces coalescence of materials by
heating them with or without the application of what? - answer-Pressure or Filler Metal.
, QUESTIONName three items that are manufactured using welding. - answer-Ships, Buildings, and
Bridges.
QUESTIONName three popular welding processes. - answer-Oxyacetylene Welding (OAW), Shielded
Metal Arc Welding (SMAW), and Gas Tungsten Arc Welding (GTAW).
QUESTIONWhat two welding processes are semi-automatic processes? - answer-Gas Metal Arc
Welding (GMAW) and Flux Cored Arc Welding (FCAW).
QUESTIONHow is a high-temperature flame produced at the torch tip in Oxyacetylene Welding
(OAW) and Torch Brazing (TB)? - answer-Acetylene gas is mixed with oxygen gas causing a bright,
hot flame.
QUESTIONName two commonly used thermal cutting processes. - answer-Oxyfuel Gas Cutting
(OFC) and Plasma Arc Cutting (PAC).
QUESTIONWhich cutting process uses a forceful stream of oxygen flowing out a center hole in the
tip to burn away hot steel? - answer-Oxyfuel Gas Cutting (OFC).
QUESTIONWhat cutting process uses a stiff, highly ionized, extremely hot column of gas to almost
instantly vaporize the metal being cut? - answer-Plasma Arc Cutting (PAC).
QUESTIONList three factors that can help determine which welding process to select for certain
job. - answer-Availability of equipment, Repetitiveness of the operation, and quality requirements.
QUESTIONName three methods used to perform welding, cutting, or brazing - answer-Manual
Operation, Semiautomatic Operation, and automated operation.
QUESTIONName five different types of welding career opportunities. - answer-Tack Welders,
Welding Operators, Welders' Helpers, Welder Assemblers, and Welding Inspectors.
QUESTIONWhat are some skills that entry-level welders need? - answer-Teamwork, leadership,
integrity, honesty, organizational skills, time management, understand the importance of workplace
diversity, and equal employment opportunity law.
QUESTIONWhat are the names of the two American Welding Society (AWS) levels of certification
for welders? - answer-Entry level welders and Advanced/Skilled welders.
QUESTIONWhat does the AWS abbreviation for "SENSE" stand for? - answer-Schools Excelling
through National Skills Standards Education.
QUESTIONWhat practical knowledge subject areas are covered in module one of the SENSE
program? - answer-Occupational Orientation.
