Abstract
The results of study of the effect of technological factors and groove shape on deformability and cyclic fatigue life of welded joints of rail steel are given. Dependences of variations in deformability h_cr of butt joints with the V- and U-shaped grooves on the welding heat input, preheating temperature and conditions of cooling of the joints after welding are presented. The technology of arc welding of longitudinal joints in rail ends of railway frogs was developed.
 
 
Keywords: arc welding, rail steel, ends of rail frogs, welded joints, deformability, cyclic life, fracture resistance
