Selection of Arc Welding Parameters of Micro Alloyed Hsla Steel
ثبت نشده
چکیده
Like all steel types, HSLA requires a definition and strict practical adherence to welding parameters in order to achieve the required weld quality. Different sources offer a varying array of welding parameters. Although their hierarchical importance can be disputed, their principal definition and practical adherence are prerequisites for the quality of welded joints 1,2 . The analysis of earlier data from tests on steels of same or similar mechanical properties and chemical compositions enable pinpoint testing of new steels, shorter and cheaper research and a comparison of results obtained by different authors. A contribution to weldability research of this particular group of steels will increase the reliability of welded joints – this is of particular importance for products at higher risk of manufacturing flaws, as well as Stress Corrosion Cracking (SCC) and failure during exploitation.
