During various welding processes workers are exposed to activities connected with audible and ultrasonic noise. In spite of the continuous development and improvement of production means, robotisation of welding works and the development of measures protecting workers against noise, the exposure to noise continues to be one of the major issues in welding engineering. The article presents experimental tests focused on the effect of gas-shielded metal arc welding technological conditions on the level of sounds generated during welding processes. The study discusses the results of tests performed for 7 selected gas-shielded arc welding methods, i.e. MAG, MAG Pulse, CMT (Cold Metal Transfer), ColdArc, RapidArc, MAG Double Pulse and AC Pulse. The test-related analysis was concerned with the correlations between welding material-technological conditions and the acoustic pressure level of sound A as well as the acoustic pressure level in the 1/3 octave bands of audible and ultrasonic noise spectrum.
