Direct current with straight polarity is used
AnswerB.
Direct current with reversed polarity is used
C.
Alternating current is used
D.
Any one of these
Answer: Option A
Solution
Answer: Option A
Solution:
In welding copper alloys with TIG arc welding Direct current with straight polarity is used Copper and copper-base alloys have specific properties which make them widely used. Their high electrical conductivity enable their use in the electrical industries, and the corrosion resistance of certain alloys makes them very useful in the process industries.
