摘要： The invention relates to a welding method, especially an arc welding method for carrying out a welding process. According to the inventive method, a welding rod (13) that melts off in an arc (15) is used, which welding rod is supplied with power by at least one regulated source of current (2).

摘要： In a pulse welding apparatus which effects the arc welding or the short-circuiting arc welding utilizing pulse discharge that generates at the tip of the wire electrode, the contact position becomes irregular in the torch chip of wire electrode due to bend in the wire electrode and the arc length changes instantaneously between the tip of the wire electrode and the material to be welded, causing the molten mass to be removed irregularly. In order to detect instantaneous change in the arc length, therefore, the arc voltage and arc current are detected between the wire electrode and the material to be welded, the detected arc voltage is converted into a reference arc voltage change and is then compared with the above detected arc voltage, to calculate a true arc length that changes from time to time. There are further set a mimic arc length signal and a mimic welding current reference waveform whose levels change depending upon the welding steps, the mimic arc length signal is compared with the calculated arc length signal, and the mimic welding current reference waveform is corrected depending upon a difference in the signals to produce a welding current waveform which is then instantaneously controlled depending on the detected arc length or the wire feed speed to quickly obtain an ideal arc length. In the welding steps, furthermore, the wire electrode performs stable welding maintaining the mimic arc length.
摘要翻译：在利用在线电极的尖端产生的脉冲放电的电弧焊接或短路电弧焊接的脉冲焊接装置中，由于线电极的弯曲，线电极的焊炬芯片的接触位置变得不规则，电弧长度在线电极的尖端和被焊接材料之间瞬间变化，导致熔融体不规则地去除。因此，为了检测电弧长度的瞬时变化，在线电极和待焊接材料之间检测电弧电压和电弧电流，将检测到的电弧电压转换为参考电弧电压变化，然后与检测到电弧电压，计算出不时变化的真弧长度。进一步设置模拟弧长信号和模拟焊接电流参考波形，其电平根据焊接步骤而变化，将模拟弧长信号与计算出的电弧长度信号进行比较，并且模拟焊接电流参考波形根据产生焊接电流波形的信号的差异，该焊接电流波形根据检测到的电弧长度或送丝速度瞬时控制，以快速获得理想的电弧长度。此外，在焊接步骤中，线电极保持模拟弧长度的稳定焊接。

摘要： A welding control method alternately repeats a short circuit period, during which a welding wire and an object to be welded short-circuit, and an arc period, during which an arc is generated and discharged, to weld the object to be welded. The method compares average output voltage, which is an average of welding voltage calculated during welding, to set voltage preliminarily set, and controls a welding output current produced when an arc is generated based on the comparison result therefrom, to regulate the meltage of the wire for adjusting the arc length, which brings the short circuit cycle closer to a constant one when a disturbance (e.g. extended or shortened arc length) occurs.

摘要： A system and method for stabilizing a welding arc is disclosed. The method of initiating the arc includes the steps of defining a wire feed speed based on a user selected wire feed speed and then abruptly reducing the wire feed speed before the wire feed speed reaches a relatively stabilized speed for welding, thereby allowing a welding arc to initiate and propagate to a generally steady state.

摘要： An arc length controlling method that is used in the practice of the pulsed welding in which welding is carried out by feeding an consumable electrode at a substantially constant speed while the pulse frequency f is set to a predetermined value. This method is carried out by effecting a welding after the counting time Tr and the target short-circuiting frequency Nr have been set, detecting the detected short-circuiting frequency Nk, and controlling the output voltage Vt to a value effective to allow the detected short-circuiting frequency Nk to be equal to the target short-circuiting frequency Nr.
