Our courses in Gothenburg
Basic Materials Technology and Failure Analysis
Provides a fundamental understanding of terminology and mechanisms within the field of metallic materials. Naturally, its scope is the material used within the vehicle industry. Among other things, it treats failure analysis in detail, hardening mechanisms and material selection. Moreover, a practical demonstration will show how materials are analyzed through microscopy, metallography and tensile testing.
Thermal spraying is a rather unknown technology but it expands rapidly. This course gives an introduction about thermal spray technology and how it can be used to give specific properties to surfaces. The different processes are presented, as well as some applications (research and industry) and guidelines for designing a coating.
This course is best suited for people working with cast components such as cylinder blocks and heads, chassis brackets and castings. The course discusses casting processes, castings design, mechanical properties, and microstructure. It also focuses on different cast materials such as grey iron, Compacted Graphite Iron (CGI), nodular iron, aluminium and magnesium.
Screw Joints – Basic
There are over 2000 screw joints in a truck. This course gives an introduction to screw joint technology. Basic features such as strength classes and static strength is covered. Influence of friction and settlements on clamping forces are shown. The importance of joint stiffness considerations for fatigue strength is discussed together with different assembly methods. Some practical examples are presented together with rules of thumb for screw joint design.
Screw Joints – Calculations
This course is best suited for designers who want to learn more about calculations and measurements of screw joints. It includes basic calculation methods for static and dynamic strength, clamping forces and some statistics.
Steel, Heat Treatment and Forging
This course discusses steel manufacturing, heat treatments, forging methods, blasting & shot peening and pressure rolling. Correctly executed heat- and surface treatments will increase component performance considerable whereas incorrect treatments can be disastrous for a component.
Tribological questions do not always have easy answers. For instance, switching to a harder material might sometimes increase the damage of wear rather than reducing the damage. This course is developed to give a basic understanding of surfaces and their properties during friction and wear. How can, for instance, wear and friction problems be prevented? The course will discuss different types of wear and how various surface coatings can reduce such problems. Furthermore, a presentation of the process for a number of common surface treatments is also included in the course.
Several important components/systems (e.g. turbo, injection system, exhaust after-treatment system, exhaust manifold) in our products are exposed to high temperatures, which in combination with a harsh environment (e.g. urea) may lead to extensive high-temperature corrosion that in turn leads to failure. The aim of this course is to give a general understanding of high-temperature corrosion in order to make it easier for designers to minimize the risks for high-temperature corrosion when designing components/systems for high operating temperatures.
Sintered steels are produced to net shape without machining, and the number of sintered products in the vehicle industry is constantly increasing. The course discusses manufacturing processes, properties and design issues regarding sintered steel.
Corrosion – Focus on engine components
The aim of this course is to give a general understanding of corrosion and corrosion protection:
• Why do metals corrode?
• Corrosion mechanism
• Different types of corrosion
• Corrosion protection
The course has a focus on engine components, including air inlet and exhaust parts.
Welding and Brazing Methods
The course discusses welding and brazing of the most common components and base materials. Areas of focus are different weld and braze methods, how welding affects the properties of the base materials, defects in welds and Volvo standards for welding.
The importance of residual stresses and their affect on the fatigue life of industrial components makes it very important to be measured both on the surface of the material and beneath the surface to a certain depth of measurements. Different manufacturing processes and heat treatments give different levels of residual stresses in the components, which make it very interesting to be known and examined even for further researches. There are many different ways for measuring residual stresses and the X-Ray diffractions method considered to be the most efficient industrial method nowadays.
