Helium leak detection

Technologie du vide
MS112 - 14 hours

COURSE OBJECTIVES

Understand the theory in relation to leak detection.
Improve the leak detection techniques: global, sniffing and accumulation tests.
Understand and interpret the results.

 

AUDIENCE

Technicians and engineers.
Management personnel
Leak detector users.

 

PREREQUISITES

Prior experience on leak detectors or vacuum installations is preferable.

 

INNOVATIVE TEACHING RESOURCES

Lectures and «hands on» exercises.
Custom training manual.
This course will provide you with knowledge and practice required to use and exploit the equipment to its full extent. It will allow you to find leaks using the helium spraying method and to quantify them by means of the global and accumulation sniffing techniques. The instructors are members of the 40-30 engineering activity and are certified COFREND level 2 or 3 (ICNDT – International Committee for Non Destructive Testing).
Prior interview with the trainees possible in order to qualify their needs.
Multiple choice questions at the start and end of the training.
Training centres integrated with 40-30 workshops.
Maximum 6 persons per group.

 

PRICE

1180 € per person
We need 3 registrations to open a session.
