actual exam with 100% verified
questions and correct solutions
A consumable electrode is: - Correct-answer-AN electrode which melts
and provides metal to fill the joint
The weld heat affected zone is: - Correct-answer-the portion of the
base metal adjacent to the weld metal whose properties have been
changed due to the heat of welding
When an arc is formed between two electrodes - Correct-answer-
electricity flows from negative cathode to positive anode
The magnetic pinch force helps in the process of the detaching the
molten metal drops from the electrode tip. The magnetic force -
