Learning outcomes 

After the course, the student is able to select the most suitable heat treatment process and to give the main characteristics of the heat treating parameters for achieving the required properties such as yield/tensile strength, ductility, toughness, surface hardness and/or fatigue strength. The student is also able to explain the metallurgical phenomena occurring in a sample during heat treatment. In the area of welding technology, the student is able to explain the most essential principles and applications of the conventional welding and cutting processes. The student is able to estimate weldability of different materials and to analyze the factors affecting weldability. The student can also explain the most essential matters regarding weld joint properties, weld defects and their inspection, and a healthy working environment. In addition, the student is generally able to take into account the effects of productivity and costs on the competitiveness.


Heat treating and welding processes, their applicability.

Mode of delivery 

Face-to-face teaching.

Learning activities and teaching methods 

Lectures (32 h), and the three laboratory exercises in small groups. The final grade is based on the points from the final exam or small exams.

Target group 

Students in the Bachelor's Phase in Mechanical Engineering; especially those who chose the course of study in Automotive and Machinery Engineering, Mechanical Design, Materials Engineering, and Industrial Engineering.

Prerequisites and co-requisites 

465101A Introduction to Materials for Mechanical Engineering; 465102A Materials for mechanical Engineering.

Recommended optional programme components 

The course is an independent entity and does not require other studies to be completed at the same time.

Recommended or required reading 

Lecture handouts (in Finnish) and other given materials.

Assessment methods and criteria 

Midterm exams or one final exam is required and accepted exercises. The laboratory exercises will be graded as pass/fail.


Numerical grading scale 1-5.
