Abstract:The existence of martensite-austenite constituents in the weld metal and heat-affected zone seriously reduces the fracture toughness of the welded joint. Therefore, we have investigated the formation of the martensite-austenite constituents when high-strength low-alloy steel is welded with a high heat input or using multi-pass welding. This paper deals with the effects of martensite-austenite constituents on the fracture toughness, the metallurgical features of the martensite-austenite constituents, and the prevention and elimination of the martensite-austenite constituents in the welded joints.
Keywords:arc welding, high-strength low-alloy steels, microstructure, martensite-austenite constituents, weld metal, heat-affected zone, cooling rate

Title:The role and formation of martensite-austenite constituents in HSLA welded joints
Abstract:Martenzitno-avstenitne sestavine v varu in na toplotno vplivanem področju drastično zmanjšujejo lomno žilavost zvara. Zaradi tega je treba posebno pozornost nameniti nastanku teh sestavin pri večvarkovnem varjenju visokotrdnostnih jekel z visoko vneseno energijo. V članku je opisan vpliv martenzitno-avstenitnih sestavin na lomno žilavost, metalurške značilnosti le-teh ter njihovo preprečevanje in odpravljanje v zvarih.
Keywords:varjenje, varjenje v zaščiti plina, visokotrdnostna malolegirana konstrukcijska jekla, mikrostruktura, martenzitno-avstenitne strukturne faze, visokotrdnostna nizko legirana jekla, var, toplotno vplivano področje, hitrost ohlajevanja
