Arc Welding objective questions and answers

26. In arc welding, if arc is too short, it will result in.......

   A.Electrode sticking to the base metal and base metal not melting and bead resting on top of the work, leading to poor fusion and gas and slag holes

   B.Formation of large globules in an irregular pattern because of wandering of arc, leading of poor fusion with base petal

   C.Arc extinction

   D.Operator hazard

   E.No welding

27. In arc welding, if arc is too long, it will result in.......

   A.Electrode sticking to the base metal and base metal not melting and bead resting on top of the work, leading to poor fusion and gas and slag holes

   B.Formation of large globules in an irregular pattern because of wandering of arc, leading of poor fusion with base petal

   C.Arc extinction

   D.Operator hazard

   E.No welding

28. Too low welding current in arc welding would result in.......

   A.Excessive piling up of weld metal, poor penetration, wasted electrodes

   B.Excessive spatter, under cutting along edges, irregular deposits, wasted electrodes

   C.Too small bead, weak weld, and wasted electrodes

   D.None of the above

29. Too high welding current in arc welding would result in......

   A.Excessive piling up of weld metal, poor penetration, wasted electrodes

   B.Excessive spatter, under cutting along edges, irregular deposits, wasted electrodes

   C.Too small bead, weak weld, and wasted electrodes

   D.None of the above

30. Too fast welding speed in arc welding would result in.......

   A.Excessive piling up of weld metal, poor penetration, wasted electrodes

   B.Excessive spatter, under cutting along edges, irregular deposits, wasted electrodes

   C.Too small bead, weak weld, and wasted electrodes

   D.None of the above
