Answer

Brief Explanations:

  • For question 6: In SMAW (Shielded Metal - Arc Welding), DCEN (Direct Current Electrode Negative) is also known as straight polarity. Reverse polarity is DCEP (Direct Current Electrode Positive). AC Balance Polarity is related to alternating - current welding and not the same as DCEN. Direct Current European Norm is not the correct term for DCEN.
  • For question 7: The given welding symbol represents a single - vee weld. A single bevel weld has a different symbol. A V - cut Groove weld is not the standard term for this symbol. A V - Butt joint is a type of joint, not the correct term for this specific weld symbol.
  • For question 8: When viewed from the top, a T - joint is represented by the shape in option A which shows a vertical member intersecting a horizontal member in a 'T' shape.
  • For question 9: A joint between two members located approximately at right angles to each other in the form of an L is a corner joint. An edge joint is different, a tee joint has a different configuration, and a lap joint involves overlapping members.
  • For question 10: When two members of a joint are aligned approximately in the same plane, it is called a butt joint. A butt weld is the weld made in a butt joint, a butting member is not the correct term for the joint, and buttering is a different welding operation.
