Abstract
Conditions of formation of stresses in arc surfacing of high-carbon steel plates are considered from the standpoint of different-orientation cold cracking. It is shown that formation of longitudinal cracks is caused in a number of cases by the presence of peaks of temporary stresses induced by martensitic transformation of austenite.
Keywords: hardenable steels, welded joints, arc surfac¬ing, martensitic transformation, residual stresses, cold cracks, preheating
