  • Must be applied to welds if a crack free weld is required
  • Should never exceed 300 dg C
  • May stress relieve
  • Must always be applied using gas flames
  1. Why have a high O.C.V. with MMA welding
  • To initiate the arc
  • To obtain penetration
  • To avoid lack of fusion

  • Radiography
  • All of the above would detect sub-surface defects
  1. What is the purpose of a ‘rectifier’ in relation to welding plant?
  • To adjust the voltage
  • To adjust the amperage
  • To convert A.C to D.C.
  • To prevent arc strikes
  1. Fish – eyes, chevron cracks and fissures are:
  • Not associated with welding
  • Types of cracks
  • Only encountered in MMA welds
  • Hydrogen related problems
  1. Pre heating prior to welding:
  • Must always be carried out
  • Need not be carried out if post heat treatment is to follow welding
  • Is always carried out using gas flame
  • None of the above
  • All of the above
  1. What does preheat prior to welding have an affected on?
  • Hardenability
  • Weldability
  • Cooling rate
  • All of the above
  • None of the above
  1. Which of the following butt-weld preparations is generally most susceptible to ‘lack of side wall fusion’ during MMA welding?
  • A ‘U’ preparation
  • A ‘V’ preparation
  • A ‘double V’ preparation
  • Lack of side wall fusion does not exist with MMA
  1. The toes of the cap on a butt weld:
  • Must overlap on the external surface of a pipe or plate by at least 1.5 mm
  • Must be grounded
  • Must never be grounded
  • None of the above
  1. What is the leg length of a fillet weld?
  • The distance from the toe to the face
  • The distance from the root and to the face center
  • The distance from the root to the toe
  • The distance from toe to toe
  1. What is ‘throat’ thickness of the fillet weld?
  • The distance from toe to the face
  • The distance from the root to face center
  • The distance from the root to the toe
  • The distance from toe to toe
  1. Quality assurance is:
  • The inspection of a product or service
  • A management system designed only to ensure material compatibility
  • Not solely related to planning and inspection
  • The implementation of quality control
  1. Which welding process is considered the most versatile?
  • SAW
  • TIG
  • MIG/MAG
  • MMA
  1. Quality assurance:
  • Is another term for inspection
  • Related to all activities and functions concerned with the attainment of quality
  • Is the activity of ensuring documents relating to specific contracts are in order
  • Is the activity of carrying out quality control
  1. Which NDT method would never be use on a 6” aluminium pipe weld?
  • Radiography
  • Magnetic particle inspection
  • Ultrasonic testing
  • Dye penetrant testing
  1. Why is hot-pass so called?
  • Because it is applied at a high amperage
  • Because it is applied when the root is still hot
  • Because it could cause ‘hot – shortness’
  • Because it heat treats the root
  1. Generally speaking a welding inspector, as a minimum requirement:
  • Must have at a thorough knowledge of NDT
  • Must know how to interpret radiographs
  • Must have a thorough knowledge of welding metallurgy
  • None of the above
  • All of the above
  1. Which of the following is not an inert gas?
  • Argon
  • Xenon
  • Carbon dioxide
  • Helium
  1. Why TIG welding is shielded?
  • To eliminate hydrogen
  • To retard the cooling rate of the weld
  • To eliminate the atmosphere
  • To ensure maximum heat input
  1. The primary duty of welding inspector:
  • Is ensure welds are defect free
  • Is to ensure the weld is free from residual stresses
  • Is to write job specifications
  • Is to ensure all welding and associated activities are carried out in accordance with the procedure(s)
  1. Which of the following welding process is most susceptible to lack of fusion?
  • Submerged arc
  • CO2 (135)
  • Manual metal arc
  • Tungsten inert gas
  1. Fillet welds are
