Which welding process is most commonly used and specified for steel building construction?
Submerged Arc Welding
Gas Metal Arc Welding
Shielded Metal Arc Welding

What is the primary function of the electrode coating in SMAW?
Acts as a filler metal
Forms a gaseous shield to protect the weld
Increases the arc temperature
Prevents oxidation of the base metal
Which of the following is not an advantage of welded connections?
More rigid and less deformation
Takes up less material and space
Easier to inspect than bolted connections
Can develop full design strength

w
0.5w
0.707w
1.414w
Which welding process uses a granular flux to form a protective gas shield?
SMAW
SAW

GTAW
What is the nominal strength of a linear weld group loaded through its center of gravity?
0.75FexxAwe
0.60FexxAwe
0.85FexxAwe
1.0FexxAwe
In a combination of longitudinal and transverse welds, which expression gives the maximum nominal strength?
Rn = Rnl+Rnt
Rn = max(0.85Rnl+1.5Rnt,1.5Rnl+0.85Rnt)
Rn = 0.85Rnl+1.5Rnt
Rn = 1.5Rnl+0.85Rnt
