19th WCNDT 2016 - Information
The conference's focus is primarily practical. The papers will communicate recent developments within individual NDT sectors in a wide range of industries and contribute to enhanced development of further applications.
We know the theory behind the 90 degree criss-cross technique.
Penetrant Testing (PT), like I said before, is one of the simpler NDT methods
Reconciliation of the documentation to complete the data packs for final hand over.
Penetrant Testing is a relatively simple method and the practical application is basic.
ASNT Level III in UT, RT, PT and MT
ASNT Level III in MT, PT, RT, UT & ET.
I was always involved in NDT in areas where certification did not exist e.g. Mechanised UT and ET
Level 2 and 3 SAQCC in MT, PT, RT and UT; I also hold ASNT Level 3 in UT and RT
This is actually a Cold Shut. When the casting was poured, some of the molten metal splashed onto the mould wall and solidified. When the rising molten metal reached the solid metal it did bot fuse and a smooth, curving cold shut was formed.
Gas Metal Arc Welding. Porosity is usually formed when the parent material is contaminated or when the shielding gas is insufficient or is deflected away from the weld pool by a breeze.
Flux Cored Arc Welding. Actually Stop Porosity or Worm Tracking. Porosity results when gas becomes trapped in the weld metal and can appear at any specific point on the weld or along its full length. Worm tracking - marks on the surface of the weld bead caused by gas that the flux in the core of the wire creates.
Actually laminations. When non-metallic inclusions are flattened out in all directions, mainly in the direction of roll it is then called a lamination.
