Nondestructive Tests (ASNT, MIL-STDs):

nondestructive testing from WJMG's independent in-house laboratoryNDT or Nondestrcutive testing can be performed using procedures and instruments that do not affect the future usefulness of the object or material. NDT allows parts and materials to be inspected, measured and analyzed without damaging or altering them. Because it allows inspection without interfering with a product's final use, NDT provides an excellent balance between quality control and cost-effectiveness.

Our testing is done in-house, in our own independent testing laboratory over seen by not only an AWS CWI, but also an ASNT Level III P.E. WJMG strives for the most complete and comprehensive reporting when it comes to the materials being inspected.
