7. In Are Welding Process, when Direct Current Straight par Straight Polarity is woed 2/3 of the total heat is released at the base metal 1/3 of the heat is released at the base metal. O All the heat is released at the base metal O No heat is released at the base metal. 8. The reason for Are Blow in Are Welding when usin in DC Current Surrounding magnetic fields created by welding sun Surrounding electrie fields created by welding sure No Are blow in Arc Welding when using DC current o Worker does not have enough experience 9. The part shown requires: O Milling Punching Blanking Punching and blanking 10. The measuring instruments shown is: o Outside caliper Inside caliper Compass Vernier Caliper o 11. The instrument which gives better accuracy in measuring diameter is Protractor o Bevel Protractor Sine bar o None of the above 12. The length of cut for the punching of the part shown is: o 13 o 21 0 42 08 is used for supporting hanging cores: o Core prints o Core seats O Chaplets o Mallet
