Metallurgy expertise and Laboratory

Metallurgy Expertise

This expertise pertains to the detailed investigation of an equipment part and its immediate environment (mechanical failure or in-service wear) to identify the causes and determine who is responsible for the problem. These two elements will make it possible for a company to seek compensation from the provider for production losses, free replacement of the comprised part, and even inspection fees.

The Lac-Mégantic Tragedy

Televised report, November 17, 2013: QMC engineer Luc Lafrenière, explains the metallurgical analyses conducted following the July 2013 train derailment and explosion.

Laboratory

Both QMC researchers and industries consult these laboratory experts who investigate materials using a variety of testing methodologies and advanced technology. Here, in compliance with established standards, quality control analyses are conducted on both the chemical and mechanical aspects. QMC facilities provide extensive services in metallurgical analysis on a wide range of metals, alloys and related products. Each inspection follows strict industry guidelines, such as ASTM, ASME, AWS, etc. and many of our tests are certified ISO 9001-2008 and ISO 17025-2005.
