Description
Предлагаетс способ электродуговой сварки нержавеюще ста.ш, например хромоникелевои, в среде защитных газов при применении метг ,л.И1ческих, уголь-гых или вольфрамовых электродов.A method is proposed for electric-arc welding of stainless steel, for example, nickel-chromium, in an environment of protective gases when using metg, lIlical, carbon, or tungsten electrodes.
Известные способы подобного рода не обеспечивают в наплав.1е;1коы метал,ле достаточного содержани азота, что приводит к умень :ению прочности сварного шва.The known methods of this kind do not provide in the welds 1e; 1, no metal, sufficient nitrogen content, which leads to a decrease in the strength of the weld.
В описываемом способе указанный недостаток устранен тем, что в качестве защитной среды примен ют азот или азот в смеси с аргоПрименение неплав щихс электродов и использование в качествеIn the described method, this disadvantage is eliminated by the use of nitrogen or nitrogen in a mixture with argon. The use of non-consumable electrodes and use as a protective medium.

Использование вместо аргона в качестве защитных газов азота или смеси азота с аргоном значительно снижает стоимость сварки.Use instead of argon as a protective gas of nitrogen or a mixture of nitrogen with argon significantly reduces the cost of welding.
Кролге того градиент потенциала дуги в среде аргона очень мал, что вызывает затруднени при проектирозании автоматов с электрическим управлением длиной дуги. При горении же дуги в смеси apiOHa с азотом или в чистом азоте градиент потенциала больше, что облегчает создание указанных автоматов.In addition, the gradient of the arc potential in argon is very small, which makes it difficult to design automata with electrically controlled arc length. When the arc is burned in a mixture of apiOHa with nitrogen or in pure nitrogen, the potential gradient is greater, which facilitates the creation of these automata.
