Butt welds qualify full and partialpenetration butt welds and fillet welds. Fillet weld tests shall be required where this is the predominant form of production welding.
This paper analyzes the unsteady-state flow of a slightly compressible fluid into a slanted well and gives an equation for calculating the partialpenetration and slanting of a well.
The penetration depth is one of the most important quality parameters in partialpenetration laser welding, and therefore real time monitoring for penetration depth becomes extremely significants.
