Opis:
The design of sheet metal parts, pressed, used in the automotive industry is very complicated. Many factors influence the final shape of the part. Contemporary designer does not need to have the knowledge needed to understand the essence of its all requirements that are placed on parts of the body. It is only important that they are aware of their existence and know who in the company can help them in their fulfilment of the construction. Nowadays, only the constructor creates a CAD model geometry, which is assumed to provide the functionality. The rest of the aspects such as the provision of adequate stiffness, manufacturability, assembly features, vibration analysis, etc., are the arena of other specialists. This is the essence of constructing simultaneous, where many cell companies often work on the same element, giving it a set of features impossible to obtain by one expert on everything. Therefore, the role of the designer is often limited to being only a CAD system operator.

Opis:
Welding with coated electrodes is still growing method of joining metals in construction machinery. If the electrodes are properly selected and current welding can weld materials in a wide range of geometric dimensions and species. With carefully selected ingredients one can introduce additional elements to the welded material and the joint during welding. An important issue in the electric welding is a welding current selection, depending on the thickness of the electrode and material thickness. The use of too low operating current cause instability and inadequate mechanical properties of the weld, resulting from insufficient melting of the material combined. Too high operating current results in the weld metal spraying and thermal overload of the electrode. For welding samples that were used to test the strength of the electrode used ESAB OK. 46.00 a diameter of 3.2 mm. Product of the company will provide a range of welding current ranging from 80 A to 150 A. The samples were welded currents amounting to 90 A, 115 A and 150 A. Due to problems with arc ignition and its instability is not made of welded samples current of 80 A.
