Weldability of steel and its carbon content

Which materials are weldable? Since the possibility of welding and welding safety can be strongly influenced by machines and aids, the consideration of the basic weldability of a substance is usually most important. It may happen that a substance that is not suitable for fusion welding, can be very well suited for a pressure welding. The weldability can therefore always be evaluated only in relation to a welding process . Weldability of components The weldability of components is decided on the basis of three criteria. Weldability is the ability of the fabric to be inseparably linked to the same or different fabric when using a welding technique. The possibility of welding refers to adequate equipment for carrying out the planned welding process, ie it is aimed at a suitable workplace. Welding reliability weighs the likelihood of deformation or other errors due to welding influences. Which properties should a weldable material have? “Weldability is available if, under consideration of qualitative and economic aspects, a spot welding meeting the requirements can be produced.” The most important ability of a substance is that it regains its strength after welding and after cooling. At the same time, however, high hot workability is beneficial for[…]
