dc.description.abstract	To accomplish a specific task just like any other technology-oriented, the 10GN2MFA steel went for diffusion welding and the welded steel has gone through the fatigue mechanical test. Diffusion welding method used for improving joint interference, especially for fatigue strength, through atomic bonding along bainitic and pearlite microstructures. However, the purpose of the master thesis is to characteristics fatigue behaviour of 10GN2MFA basic and 10GN2MFA welded steel with the constant parameter. The heating and cooling rate of welding, chemical composition, and hardness highly influenced fatigue mechanical strength. The S-N diagram revealed after diffusion weld the 10GN2MFA steel reduced nearly 24% of fatigue strength. On other hands 400 MPa the welded steel fatigue limit could not be obtained even at 105 stress cycles. This test highly influenced towards stress amplitude, where fracture happened in the joint area above endurance limit. These results were compared load to load groups with the same frequency of fatigue cycles. The thesis all main points were discussed in conclusion of this work.	cs
