1. Способ дуговой сварки соединений, стойких к электрохимической коррозии, при котором сварку ведут в несколько проходов односторонним или двухсторонним способом на постоянном токе прямой полярности, с применением металлохимической присадки и других известных мер снижения перемешивания металлической ванны, отличающийся тем, что вначале контролируют содержание кремния в основных и сварочных материалах, их подбирают так, чтобы не допускать большой разности материалов по кремнию [ΔSi≥0,30%], особенно при пониженном его содержании [0,15%≤Si≤0,25%] хотя бы в одном из материалов, а для ответственных металлоконструкций проводят пробные сварки образцов с контролем фактического химического состава сварного шва, и, если разность по кремнию между материалами любой детали и сварным швом превысит 0,30%, то материалы корректируют в сторону сближения их химических составов.1. The method of arc welding of compounds resistant to electrochemical corrosion, in which welding is carried out in several passes one-way or two-way with direct current of direct polarity, using a metal-chemical additive and other known measures to reduce the mixing of the metal bath, characterized in that they first control the silicon content in the main and welding materials, they are selected so as to prevent a large difference in silicon materials [ΔSi≥0.30%], especially at its low content [0.15% ≤Si≤0.25 %] at least in one of the materials, and for critical metal structures, test welding of samples is carried out with control of the actual chemical composition of the weld, and if the silicon difference between the materials of any part and the weld exceeds 0.30%, then the materials are adjusted in the direction of convergence their chemical formulations. Способ по п.1, отличающиеся тем, что, если разность по кремнию между материалами любой детали и сварным швом превысит 0,30%, то между такими несопрягаемыми стальными деталями вставляют прокладки из материалов промежуточного состава по кремнию, разбивая таким образом недопустимое сварное соединение на несколько последовательно расположенных допустимых сварных соединений.The method according to claim 1, characterized in that if the difference in silicon between the materials of any part and the weld exceeds 0.30%, then gaskets of materials of intermediate composition in silicon are inserted between such non-conjugate steel parts, thus breaking the invalid weld on several consecutive permissible welds.
