Abstract (2. Language): 
Welding of two pipes joined by a connector is investigated numerically and experimentally. The simulation is performed in ANSYS finite-element software using its heat-transfer and structural capabilities. To verify the simulation results, a series of experiments is conducted with four different pipe thicknesses using an automated welding process, AISI 1005 low-carbon steel as the parent metal, a gas metal arc welding (GMAW) digital power source with premixed shielding gas, and a one-sided clamping technique. Comparing the simulation and experimental results shows that three-dimensional thermo-elastic-plastic finite-element analysis can predict welding deformation. The simulation results also show that the stress distribution is located on the connector part, which experiences high temperatures in the welding process. However, as the pipe thickness is increased, the deformation becomes less because of lower residual stress.
