Study the Quality of Welded Joints of Steel S235

Abstract:

Presented article is focused on welding of structural steel using coated electrode. Weld can be defines as a permanent join of two or more materials. Welder unit was Inventor 140 GC, where was weld 6 samples with different parameters of welding. Samples were tested by non-destructive methods such as visual control, capillary method and ultrasound method. Detection of defects in microstructures was made by destructive method – metallographic method. Testing of quality provide the most suitable welding parameters for welding constructions from structural steel S 235.
