Fundamentals of welding inspection including requirements of the inspector, welding
inspection operations, quality assurance, and metric conversions
Welding processes including shielded metal arc welding (SMAW), gas tungsten arc welding
(GTAW), submerged arc welding (SAW), gas metal arc welding (GMAW), flux cored arc
welding (FCAW), electro slag welding, electro gas welding, plasma arc welding, stud welding,
oxyfuel welding (OFW), and carbon arc gouging
Test positions for welding procedures: pipe groove, plate groove, late fillet, and pipe fillet
Common welding materials: iron and iron alloys, steel (plain carbon, alloy steel), aluminum,
magnesium, copper, nickel titanium, zirconium, and tantalum
AWS electrode designation system: definitions, SMAW designations, SAW designations,
GTAW designations, FCAW designations, OFW designations, and specification briefs
Welding symbols: reference line, fillet weld symbol, fillet weld leg, orthographic views, weld
size, weld length, intermittent welds, weld-all-around, contour, finish, process methods,
plug welds, groove weld symbols, backing, melt-thru, and surfacing welds
Weld related discontinuities: hydrogen cracking, austenitic stainless steel, laminations,
lamellar tearing, dimensional, and weld discontinuities
Destructive testing: hardness testing, tensile testing, impact testing, creep testing, fatigue
testing, bend testing, chemical analysis, macrographic examination, and micrographics
metallography
Proof test
Leak test
Visual inspection
Dye penetrant inspection
