ISF AACHEN WELDING PDF

Main emphasis is put on almost all industrially relevant, non-detachable joining methods. In connection with the research work, also work about welding processing of modern materials, automation and mechanisation, process simulation, occupational safety and environmental protection are carried out. In addition to fundamental process and method analyses in the above-mentioned fields, main emphasis is put on the application-oriented implementation of the gained knowledge in the field of new and advanced development of joining technologies for innovative materials and design. Moreover, direct industrial cooperation which is reaching from smaller individual projects up to long-term development cooperation makes up a large part of the scientific work. The large spectrum of joining core competences allows to find a target-oriented solution for almost all joining problems.

Thermal Cutting Thermal Cutting Thermal cutting processes are applied in different fields of mechanical engineering, shipbuilding and process technology for the production of components and for the preparation of welding edges. The thermal cutting processes are classified into different br-ere. Classification of Thermal Cutting Processes acc. The different energy carriers for the thermal cutting are depicted in Figure Fusion cutting The material is mainly fused and blown out by a high-speed gas jet.

Sublimation cutting The material is mainly evaporated. It is transported out of the cutting groove by the created expansion or by additional gas. Electron beams for thermal cutting are listed in the DIN-Standard, they produce, however, only very small boreholes.

Cutting is impossible. Thermal Cutting Figure These are: - flame cutting - metal powder flame cutting - metal powder fusion cutting - flame planing -oxygen-lance cutting - flame gouging or scarfing -flame cleaning In flame cutting principle is depicted in Figure During the process the ignition temperature is maintained on the plate top side by the heating flame and below the plate top side by thermal conduction and Figure 1.

Figure By means of different nozzle shapes the process may be adapted to varying materials and plate thicknesses. Hand-held torches or machine-type torches are equipped with different cutting nozzles: Standard or blocktype nozzles cutting-oxygen pressure 5 bar are used for hand-held torches and for torches which are fixed to guide carriages.

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. Together with its supplementary exercises, the lecture aims to teach students the basics of material-locking joining technology. 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. Copyright: DVS Media 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.
