July/August 2011

Our redesigned monthly DPCnewsletter now draws your attention on the papers published on this Website at the same time, or reminds you of some papers already published (all of them are still available!) on the same topics as those dealt with in the new papers.

Our Website is 3 years old since April 2011! Isn’t it funny how time slips away?

Time had come for us to look not backward, but forward, to be better.

Non-aqueous wet developer: how to apply a thin, even layer from a spray can?

April 2011

Updated in June 2011

While PT has been widely used the world over for many decades, we always wonder why so few people really know how to apply the non-aqueous developer (NAWD) the right way.
As it is such a critical step, and of the utmost importance for a reliable PT inspection, this paper is intended to help every PT operator get the best results.

Magnetic particle testing: some limits to magnetization by swinging field

March 2011

Every technique has its own limits, and magnetization by a swinging field is no exception to this rule.

This article explains some of the limits of this technique and therefore is an add-on to our DPCNewsletter N°033(1).

DPCNews 033 - Swinging field technique: it works!

Magnetic particle testing and the swinging field technique: it works!

February 2011


Detecting defects in a part by MT, whatever their direction, requires running in a row two magnetizations in somewhat perpendicular directions. Quite often, this is achieved by a transverse magnetization through a direct or an indirect current flow and a longitudinal magnetization through a solenoid or a magnetic head. This NDT method needs two successive operations, which may lead to a significant waste of time.
