An ancient tradition within the FYCo has finally been brought back to life as the Kastenlauf 2021 is coming. A 2-3 hour duo event where you will hike from A to B and are required to -if you feel like winning- completing a number of tasks.

Metallurgists and scientists over the years gave gained a good understanding of the structure property relations of metals. This has led to a large variety of classes of steels specially made for specific  applications. Each type of steel has a different composition, different mechanical properties and is able to operate in a different environment. For fabricating a structure from these materials it is necessary to join them.

Fusion welding is the most common method to join two pieces of metal. For the entire structure to function, the joint not only has to meet the mechanical properties of the parent metals but in fact it has to exceed these properties in service. The properties of the parent metals are a product of processing and the thermal history. Welded joint is made up of a filler metal with a quenched structure and a heat affected zone (HAZ) in the parent metal. It is the metallurgy of welding that ensures that the joint will achieve required properties after welding.

In this colloquium we will discuss the physical process of arc welding. How the desired properties are achieved by the weld metal. Examples of practical applications of welding are discussed. Problems in fusion welding are addressed. Different developments in the welding processes are briefly outlined.
