Regulation of the phase compositions at the submerged-arc deposition under flux by addition of filler wire

The results of researches of properties of deposited metal of the different purpose, containing as one of basic structural constituents metastable austenite are presented. The necessity of controlling the amount and stability of austenite for increase of deposited metal wear-resistant is shown. The automatic submerged-arc welding with the addition of filler wire of different composition is effective method, that allowing to regulate chemical, phase compositions and properties of deposited metal and also to promote the productivity
