EVERY TEST HAS THERE OWN IMPORTANCE.

PT: is good for surface defect.
RT: is good for volumetric type defect.
UT: is good for planar type defect.

the X-ray test that is the most applicable method in the industry

PT,MT,RT,UT
These method are normally use to check the weld soundness
PENETRANT TEST ,DUE TO TO ITS EASY OF ACCESS ,LOW COST,AND MOST OF THE WELD ARE REQUIRED ONLY TO BE CRACK PROOF AS FITNESS FOR PURPOSE APPROACH,AND LPT IS VERY USEFUL IN DETECTING SURFACE CRACKS BY LOWEST OR NO AMOUNT OF SKILL.
