Title : Friction welding of dissimilar metallic materials

Abstract:

Welding is an essential assembly process in the manufacturing industry. Friction welding is a process that is becoming more and more widely used because it is an environmental process. This process is based on friction between the parts to be welded. Likewise, this process is divided into three types of welding and which are linear friction welding, rotational friction welding and friction stir welding. One of the advantages of this process is that it is used in joining dissimilar metals such as welding steel with an aluminum alloy. Despite the number of dissimilar metals welded by friction, it was noted that this number remains limited because certain challenges remain to be overcome to achieve a weld joint with good mechanical properties. This is why several research projects are being carried out to answer all the questions that require solutions.

Audience Take Away Notes:

• The public will be able to know this type of weldin
• Engineers can know the types of friction welding which is a modern welding process
• Research in the field of friction welding of dissimilar metals is current. Moreover, it can be taught in the course related to metal welding
• Friction welding solves the problem of welding dissimilar metals using conventional methods such as electric arc
• Friction welding is an environmental process because it does not emit smoke like arc welding. In addition, the friction welded joint for certain dissimilar metals has good mechanical properties compared to the arc welded joint
