Изобретение относитс к области стыкогюй контактной сварки методом непрерывного оплавлени и может быть применено при сварке встык черных и цветных .металлов.The invention relates to the field of butt fusion welding and can be applied in butt welding of ferrous and non-ferrous metals.
Известно устройство дл контрол качества сварного шва в процессе сварки, содержащее датчик перемещени сварочного издели , выполненный в виде мембраны, и св занный с ним измеритель времепи нахождени сваренного соединени под пониженным в результате образовани жидкой фазы давлением 1.A device for monitoring the quality of the weld in the welding process is known, which contains a sensor for moving the welding product, made in the form of a membrane, and a time meter for finding the welded joint under reduced pressure resulting from the formation of a liquid phase 1.
Недостатком известного устройства вл етс низка точность контрол качества сварного шва, что обусловлено инерционностью электромеханического датчика перемещени сварного соединени .A disadvantage of the known device is the low accuracy of the weld quality control, which is caused by the inertia of the electromechanical sensor of movement of the welded joint.
Наиболее близким техническим решением из известных к предлагаемому изобретению вл етс устройство,.содержащее элемент отсчета времени паузы в оплавлении, элемент сравнени , блок расчета численного значени сигнала, характеризующего качество сварки 2.The closest technical solution known to the present invention is a device containing a reference element of the pause time in the reflow, a comparison element, a unit for calculating the numerical value of the signal characterizing the quality of welding 2.
Недостатком известного устройства вл етс низкое качество контрол , так как известное устройство не учитывает изменени перемещени соедин емы.х деталей в процессе оплавлени их стыков и суммарной величины длительности пауз.A disadvantage of the known device is the poor quality of control, since the known device does not take into account changes in the movement of the connected parts during the melting of their joints and the total duration of the pauses.
Целью изобретени вл етс повышение качества контрол процесса сварки.The aim of the invention is to improve the quality control of the welding process.
Поставленна цель достигаетс тем, что предлагаемое устройство содержит датчик осадки и сумматор, при этом один вход сумматора подключен к выходу датчика осадки , другой вход сумматора подсоединен к выходу элемента сравнени , а выход сумматора подключен ко входу блока расчета численного значени сигнала, характеризующего качество сварки.The goal is achieved in that the proposed device contains a precipitation sensor and an adder, with one input of the adder connected to the output of the precipitation sensor, another input of the adder connected to the output of the reference element, and the output of the adder connected to the input of the unit calculating the numerical value of the signal characterizing the quality of welding.
На фиг. 1 изображена функциональна схема предлагаемого устройства; на фиг. 2 - график зависимости качества сварки от суммарного результата сравнени , вз того в относительных единицах.FIG. 1 shows a functional diagram of the proposed device; in fig. 2 is a graph of welding quality versus total comparison result, taken in relative units.
