Fundamentals of Joining

Joining technology is one of the key technologies in production technology, regardless wether on a manual or industrial scale. Hardly any product can do without them. The book “Fundamentals of joining technology – welding, brazing and adhesive bonding” offers an introduction to this technology.

Together with its supplementary exercises, the lecture aims to teach students the basics of material-locking joining technology. It is divided into two parts:

The first part of the lecture teaches the material basics (dealt with more intensively in the lecture “Joining Technology II”) in the welding processing of steel as well as basic knowledge about welding processes commonly used in trade and industry, such as arc, beam and resistance welding processes, in their basic variants and mechanical joining. Derived from the functional principles, possible applications and limits are explained. This part of the lecture is completed by recommendations on welding and process-compatible design (intensively dealt with in the lecture series "Joining Technology III") as well as on the necessary occupational safety.

This is to enable students to select suitable joining processes for common joining tasks. Furthermore, they will be familiar with the material and design conditions necessary for their process-safe use as well as the necessary occupational safety measures.

This basic knowledge is extended in the second part of the lecture. Variants of the welding processes learned in the first part are presented which, as improvements of the original versions, extend their fields of application or are more economical. Mechanization and automation concepts for integrating welding technology into industrial production will also be taught. Special welding techniques optimized for the highly effective fulfillment of specialized joining tasks as well as soldering and bonding complete the list of methods presented in the lecture series. Upon completion, the students now know the industrially relevant material-locking joining methods and can apply them for a joining task and its use. They also know the basic behaviour of steel during welding and hava a basic knowledge of the design of welded constructions.
