Abstract

Spatter generation in CO2 arc welding was investigated, using 1.2 mm solid wires with various chemical compositions. Correlation between the amount of spatter, measured by collection on a copper plate with a diameter of 1, 200 mm, and the number of short circuit longer than 1 msec were investigated. Increase of manganese, silicon, selenium and titanium in wire decrease the amount of spatter, while carbon, aluminum and REM increase the amount of spatter. However, an excess of selenium increase the amount of spatter. Spatter generating process was classified into five groups, and it was concluded that the spatter in CO2 welding was mainly caused by the explosive enengy of the arc.
