Description
Известны способы сварки в защитных газах водородсодержащих металлов и сплавов с предварительным нанесением паст и флюсов на кромки свариваемых изделий.Known methods of welding in protective gases of hydrogen-containing metals and alloys with the preliminary application of pastes and fluxes on the edges of the welded products.
Однако эти способы не обеспечивают получени сварных швов без газовых пор.However, these methods do not provide welds without gas pores.
Предложенный способ отличаетс от известных тем, что реагент (флюс) нанос т на свариваемое изделие в виде суспензии, состо щей из органической летучей жидкости, например этилового спирта, и взвеси тонкоизмельченных порошков химически активных веществ преимущественно фтористых солей кальци или магни , вз тых в соотношении 15-30 г на 100 .ил жидкости. Реагент в силу его активности нанос т равномерным слоем не более 25 мк.The proposed method differs from the known ones in that the reagent (flux) is applied to the product to be welded as a suspension consisting of an organic volatile liquid, such as ethyl alcohol, and a suspension of finely divided powders of chemically active substances, mainly calcium or magnesium fluoride salts, taken in the ratio 15-30 g per 100.il liquids. The reagent, due to its activity, is deposited with a uniform layer of no more than 25 microns.
В результате повышаетс проплавл юща способность дуги, предотвращаетс образование газовой (водородной) пористости в швах и возможна качественна сварка водородсодержап:1их металлов и сплавов с температурой плавлени более 1000°С, например титана и его сплавов.As a result, the arc melting capacity is increased, the formation of gas (hydrogen) porosity in the seams is prevented and high-quality welding of hydrogen-containing materials is possible: 1 of their metals and alloys with a melting point of more than 1000 ° C, for example titanium and its alloys.
