Abstract
The research investigated properties of aluminum bronze welded to structural steel St 52-3 N. Surface material CuAl-A3 was welded in one and two layers. There were dimension, metallographic examination of structures and hardness measured before and after heat treatment and after pressurization of tested specimens. It was determined that the specimens achieved the best performance by welding two layers of surface material, by postweld heat treatment and by “hammering“.
