# QMOS expertise laboratory

## As an industrialist you are looking for a laboratory capable of carrying out a QMOS expertise

### What is QMOS expertise?

QMOS expertise assesses the ability of a welder or company to make welds that meet the required standards and technical specifications. QMOS qualification is often required for construction and manufacturing projects where welds are critical to the safety and quality of the final product (shipbuilding, pipelines, bridges, industrial buildings, etc.).

The FILAB laboratory inspects welds to ensure that they meet the required quality standards.

## The FILAB laboratory carries out QMOS expertise of welds

Welding failures can be various:

- Welding process failure
- Mechanical failure
- Corrosion problem
- Quality control

With methods adapted to each of your samples, controls and characterisation examinations will allow us to identify the causes of a weld failure and to set up immediate corrective actions.
