True or False?
Weld steel shrinkage isn't proportional to the quantity of weld metal. - ANSFalse
True or False?
Longitudinal residual stress may be as excessive because the yield strain of the base steel. -
ANSTrue
True or False?
There isn't any residual stress in a metallic plate with mill rolled edges without any additional
head remedy - ANSFalse
True or False?
Oxy-gas gas slicing alongside square metallic plates usually causes distortion. - ANSFalse
What is the subsequent formula applicable to?
S = 0.18 Aw / t + 0.05d - ANSTransverse shrinkage - butt welds
What is the subsequent method relevant to?
S = zero.0.5 Aw / Ar - ANSLongitudinal shrinkage - butt welds
In seam welding, what is the only form of distortion manipulate? - ANSStart on the equal
distance from the cease of the joint, creating a quick weld first
True or False?
Where planting and stiffeners are mixed as a deliver bulkhead work, the butt and seam welds in
plating should be welded before the stiffeners. - ANSTrue
True or False?
In filling up a weld joint, the variety of weld passes does now not have an effect on distortion. -
