El principio de la fabricación de tubos de acero soldados por alta frecuencia ERW
El principio de la fabricación de tubos de acero soldados por alta frecuencia ERW

La tubería de acero con costura recta ERW se fabrica mediante el uso del efecto superficial de la corriente de alta frecuencia para calentar rápidamente el borde del tocho de tubería formado a la temperatura de soldadura y luego extruirlo y soldarlo. Según los diferentes métodos de alimentación, los tubos soldados ERW se pueden dividir en soldadura por contacto de alta frecuencia y soldadura por inducción de alta frecuencia. Ambos utilizan el efecto de piel y el efecto de proximidad de la corriente de alta frecuencia y, al mismo tiempo, se sueldan a presión en tuberías de acero bajo la acción de rodillos de extrusión.


ERW pipe ASTM.jpg


La tubería de acero con costura recta para soldadura por contacto ERW utiliza dos electrodos o pies de soldadura para hacer contacto con los dos bordes del tubo formado, respectivamente. El efecto de piel y el efecto de proximidad generados por la corriente de alta frecuencia se utilizan para concentrar la corriente de soldadura en la muesca en forma de V y la muesca en forma de V El metal en el lugar se calienta instantáneamente a la temperatura de soldadura y al mismo tiempo , la tubería de acero se suelda presionando el rodillo de extrusión; La soldadura por inducción ERW es primero formar la bobina laminada en caliente a través de la máquina formadora en un tubo, cuando el tubo pasa a través de la bobina de inducción (alta frecuencia La bobina de inducción de la máquina de soldadura genera un campo magnético de alta frecuencia a través de la alta frecuencia actual), y la corriente de Foucault inducida de alta frecuencia se generará en el tubo, y luego el efecto de piel y el efecto de proximidad de la corriente de Foucault de alta frecuencia se utilizarán para hacer que la corriente de Foucault sea densa en el borde del tubo. Muesca en forma de V, la pieza en bruto del tubo formado se calienta rápidamente a la temperatura de soldadura debido a su propia resistencia y, al mismo tiempo, se suelda a presión en una tubería de acero bajo la extrusión del rodillo de extrusión.
