Practical Guidance For The Prevention Of MPI Indications During Welding
Don’t fall into this trap!
Unnecessary repairs from MPI indications rather than genuine cracks can slow a job down – costing the workshop time and money.
We’ve created a practical guidance document that can be used directly in the workshop to help welders understand:
· How and why magnetic particle indications occur.
· What common operator induced defects look like.
· The root causes behind issues like crater piping/cracks, overlap/cold roll, and non-relevant indications.
· Simple & practical prevention techniques that can be applied immediately.
Because the reality is that MPI testing, which is required as a percentage in most contract specifications, should be breezed through if a workshop has their welding under control and rather than just identifying indications during inspection, this cheat sheet focuses on prevention, preparation & improving techniques to ensure there’s no costly hold ups at the end.
This downloadable guide is designed to be posted on the wall of a workshop and support welders in producing compliant, high quality welds the first time.
