 Classification of the Thermal Cutting Processes

Classification of the Thermal Cutting Processes

Thermal cutting processes can be classified according to different aspects. According to the common physical processes, a distinction can be drawn between flame cutting, fusion cutting and sublimation cutting. The material is treated as follows: When flame cutting, it is mainly burned, and the combustion products are expelled by an oxygen jet of high kinetic [...]

Basic of weld design – Stresses in Welded Joints

Upon explaining the material stresses resulting from the action effects axial force N, shear force V and bending moment M. The peculiarities of stresses in welds and welded joints are considered. The stresses in welds can be categorised as to the kind and direction of the actions and the type of weld. Axial stresses parallel [...]

Ignition of the arc

Ignition of the arc

The welding arc is ignited by direct contact of the electrode with the workpiece. Due to a short circuit a high current density is created in the contact area. By this means, the melting phase and the metal vapour is formed, by which the ionisation can start quickly. The arc increases as soon as a [...]
