Claims (2)

1. Способ сварки плавлением изделий с замкнутым внутренним объемом, характеризующийся тем, что сварку ведут в несколько проходов в защитном газе, при этом после первого прохода повышают давление газа и выполняют, по меньшей мере, один последующий проход, причем переплавляют металл сварного шва предшествующего прохода в объеме, соответствующем глубине расположения образовавшегося дефекта, но не более чем на 98%.1. The method of fusion welding of products with a closed internal volume, characterized in that the welding is carried out in several passes in a protective gas, and after the first pass, the gas pressure is increased and at least one subsequent pass is performed, and the weld metal of the previous pass is remelted in a volume corresponding to the depth of the location of the defect, but not more than 98%. 2. Способ по п.1, характеризующийся тем, что в качестве защитного газа используют преимущественно инертные газы, углекислый газ.2. The method according to claim 1, characterized in that inert gases, carbon dioxide, are mainly used as protective gas.
