Description
Известен Способ дуговой сварки с поперечными колебани ми.A known method of arc welding with transverse vibrations.
Предлагаемый способ отличаетс от известного тем, что ось колебани электрода в процессе сварки совмещают с нормалью к поверхности свариваемой детали в зоне сваркт путем сравнени напр жений в симметричных относительно оси колебаний точках. Это позвол ет повысить качество сварки.The proposed method differs from the known one in that the axis of oscillation of the electrode during the welding process is combined with the normal to the surface of the welded part in the zone of welding by comparing the stresses at points symmetric with respect to the axis of oscillation. This improves the quality of welding.
Сущность предлагаемого способа по сн етс чертежом.The essence of the proposed method is illustrated in the drawing.
Способ основан на линейной св зи напр жени дуги с ее длиной и заключаетс в том, что ось ОА колебаний электрода поворачивают вокруг точки О сварки до положени ралеиства напр жений Ljj и д, сварочной дуги в симметричных относительно оси колебаний точках Б и В траектории движени сварочной дуги.The method is based on a linear connection of the arc voltage with its length and is that the axis OA of the oscillations of the electrode is rotated around the welding point O to the position of the voltages Ljj and d, the welding arc at points B and B symmetrical with respect to the axis of oscillation of the welding motion path arc.
Овар-ку по предлагаемому способу ведут следующим образом.Ovar-ku on the proposed method are as follows.
Электрод сварочной горелки выставл ют строго над стыком (точка О) свариваемых поверхностей , заж1игают сварочную дугу и придают электроду поперечные колебани , симметричньге относительно стыка. Замер ют величины напр жений б .ц и сварочной дугиThe electrode of the welding torch exposes strictly above the joint (point O) of the surfaces to be welded, clamp the welding arc and give the electrode transverse oscillations that are symmetrical with respect to the joint. Measurements of voltages b. C and welding arc
в симметричных относительно оси колебаний точках Б и В и определ ют разность этих ъ&лпчин . После этого поворачивают электрод (ось его колебаний) относительно точки сварки и плоскости, проход щей через точки Б и В и ось колебаний электрода, до сведени разности At/д напр жений к минимуму (нзлю).at points B and C symmetrical with respect to the axis of oscillation, and determining the difference between these b & After that, the electrode (the axis of its oscillations) is rotated relative to the welding point and the plane passing through points B and C and the axis of oscillation of the electrode, to reduce the difference At / d of voltages to a minimum (ground).
Если сварку производ т с автоматической стабилизацией напр жени (и длины) дуги, в качестве сигнала ошибки используют вы .ходное напр жение, например, потенциометра, ползунок которого соединен с выходным валом механизма осевого перемещени горелки и электрода.If welding is performed with automatic voltage stabilization (and arc length), you use an input voltage, such as a potentiometer, the slider of which is connected to the output shaft of the axial movement mechanism of the torch and electrode as an error signal.
Предмет изобретени Subject invention
Способ дуговой сварки неплав щимс электродом с поперечными колебани ми от носительно свариваемого стыка, отличающийс тем, что, с целью улзчщени качества при сварке кольцевых щвов, ось колебани электрода в процессе сварки совмещают с нормалью к поверхности свариваемой детали в зоне сварки путем сравнени напр жений в симметричных относительно оси колебаний точках.The method of arc welding with a non-consumable electrode with transverse vibrations relative to the welded joint, characterized in that, in order to improve quality when welding annular welds, the axis of oscillation of the electrode during the welding process is aligned with the normal to the surface of the welded part in the welding zone by comparing stresses in symmetric about the axis of oscillation points.
