Q:- Some codes require the excess weld metal (weld cap) on cross weld joint tensile specimens to be flush ground, this is because:

• Flushed caps will always break in the weld metal area 
• This is to remove any porosity in the excess weld metal (weld cap) 
• It is easier to calculate the cross section areas of the joint when fused 
• Flushed caps have fuser stress raisers and therefore give a more aqua rate result
