Question

4.) shielded metal are welding is also called *
a.) brazing
b.) electrode welding
c.) oxyacetylene welding
d.) stick welding

Explanation:

Shielded metal arc welding (SMAW) is commonly known as stick welding. In this process, a consumable electrode (covered with a flux) is used. The flux melts and forms a gas shield that protects the weld pool from atmospheric contamination. Brazing (A) is a different joining process where a filler metal is used that melts at a temperature above 450°C but below the melting point of the base metals. Electrode welding (B) is a very general term and not the common name for SMAW. Oxyacetylene welding (C) uses a fuel gas (acetylene) and oxygen to produce a flame for welding.

Answer:

D. stick welding
