Claims (1)

Горелка для дуговой сварки в защитных газах, содержащая токоподводящий канал для направления плавящегося электрода, мундштук и сопло, соединенное с каналом подвода защитного газа, отличающаяся тем, что сопло выполнено длиной L, определяемой по формуле
Figure 00000001

где D - диаметр выходного отверстия сопла 3, D1 и D2 - внутренний и внешний диаметры кольцевого канала соответственно, L2 - длина основной части сопла, представляющей собой кольцевой цилиндрический канал, а длина L1 конусной части сопла равна: L1= 2•D. Угол конусности β2 внешних стенок выходной части сопла не больше угла конусности внутренних, последний из которых равен β1 = 8°.A torch for shielded gas arc welding, containing a current supply channel for guiding the consumable electrode, a mouthpiece and a nozzle connected to the protective gas supply channel, characterized in that the nozzle is made with a length L defined by the formula
Figure 00000001

where D is the diameter of the outlet nozzle 3, D 1 and D 2 are the inner and outer diameters of the annular channel, respectively, L 2 is the length of the main part of the nozzle, which is an annular cylindrical channel, and the length L 1 of the conical part of the nozzle is equal to: L 1 = 2 • D. The taper angle β 2 of the outer walls of the outlet part of the nozzle is not greater than the taper angle of the inner ones, the last of which is β 1 = 8 ° .
