uphill pipe welding typically requires a thicker root face than downhill welding?
true
false

Explanation:

Question 23

E7018 is a low - hydrogen electrode, but after the root pass, not all pipe welds can be welded with it. There are factors like the welding position, pipe thickness, and specific welding requirements that may restrict its use. So the statement is false.

In uphill pipe welding, due to the way the molten metal behaves (gravity - related and the need for better fusion and control), it typically requires a thicker root face compared to downhill welding. So the statement is true.

Answer:

False
