(54) СПОСОБ КОНТРОЛЯ ГЛУБИНЫ ПРОПЛАВЛЕНИЯ ПРИ ЭЛЕКТРОННОЛУЧЕВОЙ СВАРКЕ Изобретение относитс  к области электроннолучевой сварки. Известен способ контрол  глубинь. проплавлени  при электроннолучевой сварке по величине смещени  сварног шва относительно стыка с предварительной фиксацией местоположени  стыка 1. Недостатком этого способа  вл ет с  СЛОЖНОСТЬ контрол  глубины проплавлени  из-за необходимости нанес ни  на поверхность издели  рисок ме ханическим путем. Целью изобретени   вл етс  упрощ ние процесса контрол  глубины проплавлени . Это достигаетс  тем, что после сварки на поверхность верхней части шва без изменени  взаимного положеВИЯ луча и стыка нанос т риску лучо малой интенсивности и глубину проплавлени  определ ют по смещению этой риски. На чертеже показана схема осущес влени  способа. На поверхности издели  со стыком 1 и швом 2 без изменени  взаимного положени  луча и стыка лучом малой интенсивности нанос т риску 3. Определ ют рассто ние между риской 3 и стыком 1 и, зна  поперечное сечение шва, определ ют глубину проплавлени  h, что упрощает контроль глубины проплавлени  в результате отказа от дорогосто щей механической обработки. Способ осуществл ют следующим образом . Провод т контроль глубины проплёшлений цилиндрического издели  электронным лучом со следующим режимом сварки: ускор ющее напр жение 40 кВ, ток луча 10 мА, ток фокусировки 565 мА, скорость сварки 1 об/мин, фокусное рассто ние 50 мм.

После сварки без изменени  относительного положени  луча и стыка сосуда на сварный шов нанос т риску электронным лучом при токе X, 2 мА, соверша  полный оборот издели . Так как электронным лучом малой интенсивности повтор ют траекторию сварочного луча, риска оказываетс  точно по середине сварного шва.

Known way to control the depths. penetration during electron beam welding with respect to the weld displacement relative to the joint with preliminary fixation of the location of the joint 1. The disadvantage of this method is the COMPLEXITY of controlling the penetration depth due to the need to apply a risk to the surface of the product in a mechanical way. The aim of the invention is to simplify the process of controlling the depth of penetration. This is achieved by the fact that after welding, on the surface of the upper part of the weld, without changing the mutual position of the beam and the joint, the risk of a low intensity beam is put at risk and the penetration depth is determined by shifting this risk. The drawing shows a scheme for implementing the method. At the surface of the product with butt 1 and seam 2, without changing the mutual position of the beam and the butt with a low intensity beam, risk 3 is determined. The distance between pin 3 and butt 1 is determined, and the penetration depth h is determined, which makes the control easier penetration depths as a result of the abandonment of expensive machining. The method is carried out as follows. The depth control of the cylindrical product is controlled by an electron beam with the following welding mode: accelerating voltage of 40 kV, beam current 10 mA, focusing current 565 mA, welding speed 1 rpm, focal length 50 mm. Before welding, the distance from the joint to any PLANE on the product to be welded is fixed. After welding, without changing the relative position of the beam and the junction of the vessel, the weld is applied to the risk of an electron beam at a current X, 2 mA, making a full turn of the product. Since the low-intensity electron beam repeats the trajectory of the welding beam, the risk is exactly in the middle of the weld. Then, a linear measurement determines the displacement in the applied risk relative to the previously fixed location of the joint and, knowing the cross-sectional shape of the weld, the penetration depth is determined from the detected displacement.
