接触焊接具有高度的生产率,并且能够在电热过程中自动控制焊接热量,使焊接质量达到令人滿意的要求,因此在工业上获得广泛采用我国目前生产的自动点焊机及自动縫焊机中,电热过程的自动控制設备如XN型及XQ型同期引燃管断续器等,都是比較精密的,其控制性能已远远超过一般电磁接触器、半同期电磁接触器及非同期引燃管接触器等要求。在通常情况下,使用这类控制设备已足够达到滿意的焊接质量。但是随着工业的
Contact welding has a high degree of productivity, and can automatically control the welding heat in the electrothermal process, the welding quality to meet the satisfactory requirements, so widely used in industry, China’s current production of automatic spot welder and automatic seam welder, Electrothermal process control devices such as XN-type and XQ-type simultaneous pilot tube interrupter, etc., are more sophisticated, and its control performance has far exceeded the general electromagnetic contactor, semi-synchronous electromagnetic contactor and non-synchronous pilot tube Contactor and other requirements. Under normal circumstances, the use of such control equipment has been sufficient to achieve satisfactory welding quality. But with the industry
