The hulls of vessels, components of ship engineering, pipelines in domestic shipbuilding, etc., are produced using advanced materials and methods of arc welding. The latter include mainly manual welding with coated electrodes, automatic and mechanised submerged-arc welding of steels and CO sub 2 welding, manual and mechanised welding in argon and nitrogen of alloys based on aluminium, copper and titanium. The introduction into production of a large range of structural and welding materials, the methods of arc welding, etc., has necessitated investigations into the effect of welding technology on the nature of emission of the electric arc in order to determine the harmful effect of this emission on the eyes, the efficiency of industrially produced means of protection of the eyes and the correspondence of the parameters of the domestic light filters to the physiological special features of the eyes. Welding trials were carried out using low-alloyed hulls of steel 09G2, AMg6l aluminium-magnesium alloy, VT6 titanium alloy and MNZh5-1 copper-nickel alloys.
