Metallurgy - Introduction and basics

OBJECTIVES

At the end of the training course, the trainee will be capable of doing the following :

 interpret a material certificate,

 assess the manufacturing conditions and the significance of the results of basic mechanical tests,

evaluate the effects of cold and hot distortion,

understand the various heat treatments and to evaluate their consequences on operating characteristics,

 establish a dialogue with a metallurgist in order to optimize a manufacturing process or to check the operating characteristics,

classify steels in families, based on their standardized designation,

undergo specialized training in the metallurgy of welding.

 

SUITABLE FOR

Technicians and engineers, non specialized in metallurgy and confronted with the problems of implementation of metallic materials, wishing to specialize in the metallurgy of welding.

DURATION

5 days i.e. 35 hours.
 

GENERALITIES :

The course provides an introduction to the basics of metallurgy required for the implementation of metallic materials, with respect to welding. It is an essential precondition to acquire the indispensable knowledge required to get to the metallurgy of welding.

TEACHING

Active, dynamic and participative, alternating theoretical overviews with case studies. Lectures illustrated with video films, parts, macro and micrographs.
 
The Metallurgy MA1 and Metallurgy MA2 courses are fully complementary, and constitute an excellent basic training in the metallurgy steels welding.
