Support about PT method

Hello everyone
I have 2 question want to ask you. Please share
1) Which PT method is not only sensitivity but also reducing cost?
2) Which PT method is applied for weld joints of large tank?
Thanks

My opinion Dye Penetration Testing Colour Contrast Water Washable would satisfy your requirements especial with welds on large storage tank.
For sensitivity, you can use PT crack test panel to verify the sensitivity of the method applied.

Color contrast water washable not only faster but it also provide distinct advantage unlike solvent removeable method thats leave lots of back ground colors due to insufficent removeable by manual lint free cloth solvent wipes on uneven weld joint surface that leave interpretation huge challenge.
