The Mathematical Model

The method and results of the study of reverse extrusion of billet by cylindrical punch in a conical expanding matrix are described. The mathematical model, which we developed for the determination of specific extrusion force, is described too. The study by statistical method verified the adequacy of the model. This model made possible to assess the resistance of punches and showed the ability to produce deformation of a billet made of low carbon steel without heating. The developed process includes the operation of segmenting of the cylindrical workpieces from bar, heat treatment, lubrication and extrusion of the workpieces. The two-way cold extrusion of a billet is produced in a matrix alternatively by two punches. The design of the stamp is described. The stamp is specialized for reverse extrusion of a billet. In its construction the moving mechanism of action of the two alternately punches in one matrix is used.

Selection Of

The strength of the welding result is strongly influenced by several factors, one of which is the selection of high current. This study aims to determine the effect of high current of welding on the strength of low carbon steel welding joints. The process of welding the material uses the open V seam connection type. The variations of the high current used were 80 A, 100 A and 130 A. The specimen used was a carbon steel plate with code of 1.0038 with thickness of 8 mm and the electrode used was the E7018 electrode with diameter of 3.2 mm. The strength of the welding results is influenced by arc voltage, amount of current, welding speed, amount of penetration and electric polarity. Determination of the amount of current in metal joints using arc welding affects the work efficiency and welding materials. Based on the research, it was found that welding using high current of 100 ampere produced the highest tensile strength value of all test specimens that were given welding treatment and good penetration results.
