EBW of stainless steels and ODS ferritic steel
Original language description
Dissimilar welds are the integral part of design in chemical, nuclear and energy industries. One of the most common combinations is the joints between ferritic, austenitic and martensitic steels. These joints provide many advantages at the detriment of the worse weldability. Possible defects in dissimilar welds are caused by different physical properties of welded materials. Choice of electron beam welding (EBW) is achieved the reducing the amount of heat input into the weld and reduce the negative effects of the surrounding atmosphere. Suppression of defects can be done by the right settings of EBW parameters. Another way is right choice of the rolling direction of base materials against the orientation of weld joint, which is most occurs in a materials whose structure has grains with a large ratio length-to-width (e.g. extruded ODS steel). In this work were evaluated four heterogeneous welds of austenitic stainless steel, martensitic stainless steel and ODS ferritic steel, which vary
