Question

In DC Welding operating efficiency is
A) Very High
B) Low
(C) High
(D) Medium​

Answer 1

Answer:

answer it is A

Explanation:

DC type of current produces a lower amount of spatter, resulting in a smooth weld and higher product yield.

DC is most efficient in welding thinner metals and thus it is desirable to many welders. ... The reliability of DC type of current is higher, making it much easier to work with.

Answer 2

In DC Welding operating efficiency is Low.

• A DC welding machine has a higher cost and lower efficiency.

• A DC welding machine is a costly affair. It is also heavy in weight and more complex.
• By changing polarity, it can be used to weld any type of metal.
• The overall efficiency of the machine is very low. It ranges from 0.3 to 0.6.
