The technological heating effect in tensoresistor gluing and in welding on the mechanical and corrosion properties of martensitic-ageing steels for force-measuring elastic elements is studied. The influence of steel’s chemical composition on susceptibility to intercrystalline corrosion is analyzed; a method for improving the corrosion stability of welds at the expense of application of grit blasting is established.
