6 Testing and inspection of welds

6.2 Destructive testing
6.2.1 Mechanical test

• Tensile test
  • Stretch test metal piece of specified shape and measure stress up to break
    EX: Plstic region
    
    • Stress
    • Tensile: elongation
    • Yield Point: CD
    • Tensile Strength: E
    • Break: EF

• Bending test
  • Mold bending: Static test: Example welding defect
    • type
      • Table bending: Weight applied to welding surface
      • Back bending: weight on weld surface
      • Horizontal bending: weight on welding side
    • result
      • Undercut
      • Crack
      • Blow Hole
      • Break
  • Roller bending: Dynamic test: Omission
