Utilization of Electrical Energy MCQ PDF 2
Utilization of Electrical Energy is a important subject for RRB,SSC and others AE,JE & Technician exam, In this subject Today we are providing Electric Welding MCQ 2,In upcoming days we will cover Illumination, Electric heating, Electroplating, Electric drives and motors.
1) If the blowpipe is moved to and fro frequently while cutting the kerf will
- not be affected
- be less
- of correct size
- be more
Answer-4
2) In gas cutting, if too little cutting oxygen is supplied
- the metal will be cooled down
- the kerf will be narrow
- the kert will be wide
- the metal will fail to cut completely
Answer-4
3) The top edge is melted round and the cutface is not smooth in gas cutting. This is due to
- extremely slow cutting speed
- insufficient acetylene pressure
- the tip being held too high
- too much cutting oxygen pressure
Answer-3

4) In a gas cut plate, the cut shows groove sand has deep drag lines. This is due to
- tip too close to the cut surface
- too much travel speed
- less oxygen pressure
- smaller size cutting nozzle
Answer-1
5) In a gas cut plate, the cut is high quality although there is some surface roughness caused by vertical drag lines. This is due to
- too slow cutting speed
- smaller size cutting nozzle
- impure cutting oxygen
- less preheating flame
Answer-1
6) The size of the cutting nozzle used in oxyacetylene cutting process depends mainly on
- thickness of metal to be cut
- purity of oxygen
- duration of cut
- type of cutting blowpipe
Answer-1
