The behavior and destruction features of organosilicate coatings and its components during electric arc welding / surfacing were considered. The effects of the organosilicate compositions (OS-51-03 (green), OS-51-03 (gray), OS-56-22 (gray) and OS-82-01 (green)), its thicknesses and influence of welding parameters on the porosity and the presence of the other defects in the weld metal were investigated. Gas pores, wormholes and nonmetallic inclusions are found as typical defects in the welded joints of organosilicate coated metal. Defects formed in the weld pool crystallization zone during the physical, chemical and metallurgical processes when the coating destruction products interact with a liquid metal.
