Study of Welding Parameters Effect on the Weld Quality for Structural Steel S235 J0

Abstract

Welding technology at current level provides wide range of applications such as automotive or aerospace industries. New technique, ways of approach and use of new materials (for example aluminum or composite parts of car body parts) creates necessity of optimizing of welding.The article is focused on welding of two parts using Metal Active Gas (MAG) welding. The main task is to design most suitable parameters for welding structural steel S235 J0. Samples were prepared by CNC machining center by chamfering edges 30°. Machined samples were placed against each other creating angle of total 60°. Welding machine Einhell BT-GW 170 MAG was used to create V and Y shaped welds with various technological parameters. Goal of the article is experimentally determine combination of technological parameters for V and Y shaped weld joints of steel components with thickness of 6 mm focused on hardness. Every welding machine and of course additive material has some recommended values of parameters in large scale, therefore it is necessary to determine most appropriate combination of main welding parameters. Data obtained from experiment showed most suitable combination of variables of welding process in order to achieve highest quality of weld joint.

Simulation of Weld Elbows Hot Forming Process

“…[6]- [8] Boundary conditions define contact between workpieces to provide permanent contact during simulation process (preset COMFORM COUPLING in Deform 3D). Symmetry planes were not set by the reality from the reason of subsequent research should point on eccentricity of pipes (dimension and shape).…”
