ARC WELDING SAFETY & CALIBRATION

ARC WELDING SAFETY:

  • Every body is the safety responsibility.
  • OCV exceeded to 100v: Risk Of Fatility; Electronic Equipment may damage.
  • Duty cycle: it is safety value for welding equipment.
  • Ultraviolet radiation excess may cause skin cancer[or] permanent eye damage.
  • If you Sea a welder is welding on cadmium coated plate what action you will take as an inspector: immediately stop welding.
  • Degreasing components should be removed completely because it will produce : Toxic gases [ or] harm full gases.

 

CALIBRATION:

Calibration: determining the magnitude of errors in a measuring device.

Validation:  checking the controlled Knobs & switches provided the same level of

Accuracy when returned to a predetermined point.

Accuracy:    closeness of an observed quantity to the defined.
