Welding Quiz

What is arc blow?

• A type of weld bead made without significant weaving motion

• The deflection of the arc from its intended path due to magnetic forces

• A discontinuity consisting of localized melting of the base metal

• A defect that occurs when the cross-sectional thickness of the base metal is reduced

What does the term 'drag angle' describe?

• The angle less than 90 degrees between a line perpendicular to the major workpiece surface and a plane determined by the electrode axis and the weld axis

• The travel angle when the electrode is pointing in a direction opposite to the welding bead’s progression

• A repetitive and consistent side-to-side motion

• The straight line drawn through the center of a weld along its length

What is the function of a quench?

• To cool down a freshly welded component

• To drain into the weld puddle

• To describe a type of weld bead made by transverse oscillation

• To initiate an arc

What is a stringer bead?

• A defect that occurs when the cross-sectional thickness of the base metal is reduced

• A type of weld bead made with any significant weaving motion

• A type of weld bead made without any significant weaving motion

• The deflection of the arc from its intended path due to magnetic forces

What is an undercut in welding?

• A discontinuity consisting of localized melting of the base metal

• The deflection of the arc from its intended path due to magnetic forces

• A defect that occurs when the cross-sectional thickness of the base metal is reduced at the edges of the weld

• A type of weld bead made without any significant weaving motion
