چکیده مقاله
Paper gives an overview and main characteristics of low alloyed steels based on chromium and molybdenum as the main alloying elements Chrome moly steels are intended for high temperature applications especially for the need of energetic industry Welding issues of these steels is presented and general recommendations for welding of CrMo steels are presented In experimental part of this paper GTA welding of 10 CrMo 9 10 tubes in 5G position were performed in such a ways that approved welding procedure specification WPS was, regarding thermal conditions and prerequisites disobeyed, no preheating and no control of interpass temperatures without and with tubes restrain and with complete obeying of WPS using restrain Disobeying adequate welding procedures can result in detrimental quality loss by welding of 10 CrMo 9 10 tubes
