In a fillet weld, the effective throat thickness Te is calculated as.
Te=ks
Te=k×s
Te=s2×k
Te=sk
Deep penetration fillet welds are defined when penetration beyond the root is.
< 1.0 mm
< 1.8 mm
< 2.4 mm
≥ 2.4 mm

In butt weld design, reinforcement thickness is.
Always considered in design
Neglected in design
Equal to effective throat
Half of plate thickness
For standard fillet welds, the ratio Te : s is.
1 : 1
1 : 1.41
1 : 2
2 : 1
Gauge distance in riveted joints is also known as.
Row pitch
Edge pitch
Diagonal pitch
Effective pitch
TRUE / FALSE: The maximum size of a fillet weld with a square edge is plate thickness minus 1.5 mm.
True
False
ASSERTION–REASON: Assertion (A): Reinforcement increases the static load strength of butt welds. Reason (R): The reinforcement increases the effective throat thickness considered for design. Choose the correct alternative.
Both A and R true, R explains A
Both A and R true, R does NOT explain A
A true but R false
A false but R true
FILL IN THE BLANKS: The size of a normal fillet weld is the minimum (a) of the fillet weld.
FILL IN THE BLANKS: Effective length of a fillet weld = Actual length − (a) .
FILL IN THE BLANKS: In welded joints, the critical stress in a fillet weld is (a) stress.
