Abstract
The phase composition of the solid component of welding aerosol (SCWA) obtained as a result of metal welding with electrodes of ANO-4 and TsL-11 types manufactured according to ISO 2560 E432R 21 and ISO E19.9NbB20 standards, respectively, and differing in com-position of their wires and coatings was determined with the help of a Siemens D500 diffrac- a Siemens D500 diffrac-tometer supplied with the manufacturer’s software. Four and thirteen phases were identified in SCWA-ANO-4 and SCWA-TsL-11, respectively. Evaluation of crystallite sizes by the use of the Scherer equation showed that the crystallites formed in the course of welding with a TsL-11 type electrode are larger than those in the case of an ANO-4 type one: 65-89 nm and 30-49 nm, respectively.
