The thesis may be divided into two parts, the theoretical and practical part. In the theoretical part of my thesis describe the permanent connection in engineering includes soldering, gluing, riveting and welding and further describe the building-up and weldability tests as part of the technological tests. In the practical part of my thesis describe what and how I was doing. How I progressed in the production of individual samples and testing. We can find there a description of the tensile test, graphical display each tensile test, measured and calculated values and evaluation of tests. Further describe the detection of microstructure and microhardness. Each photo of microstructure I worked to the table and commented what can we see on them. At microhardness we can read about the gist and execution of the test. Obtained values I compiled to the chart and commented. According to the hardness can recognize a structural component and phases. In conclusion is a summary of the measured values and evaluation.
