摘要： A hot wire TIG welding apparatus has a current detector for detecting the peak period and base period of the arc current. The welding apparatus further has a controller which controls, in response to the detection signal from the current detector, the operation of the wire heating power supply such that the wire heating power is supplied only during the base period of the arc current. According to this arrangement, a hot wire switching TIG welding apparatus can be produced using commercially available power supply systems for TIG arc welders, without requiring substantial change or modification of the control circuits in the TIG arc welders.

摘要： A method and an apparatus for controlling the hot-wire welding process is disclosed in which the heating power for a hot-wire is automatically regulated to a proper value. The wire-heating power after fusing of a filler wire by being overheated is set to a level lower than the heating power immediately before wire fusing, and the wire-heating power is again increased gradually from the set value until the wire is fused by being overheated. By repeating this process, the molten state of the filler wire in the hot-wire TIG welding is automatically kept in optimum condition without requiring any operation of the welding operator or his intuition. Further, during the energization of the filler wire, the instant of fusing by overheating of the wire is detected, and the detected signal is used to sharply reduce or suspend the wire current immediately, whereby spatters which otherwise might be caused by fusing of the overheated wire is prevented or greatly reduced, and the adhesion of the spatters to the arc electrode is prevented, thereby permitting a hot-wire welding operation continuously over a long time. Furthermore, a pulsed current is used for heating the filler wire, and the wire terminal voltage during de-energization of the wire is detected, thereby detecting whether the wire is in contact with a base metal. If the wire is not in contact with the base metal, a current is not supplied during the next pulse application period, so that the current is prevented from flowing from a tungsten electrode to the wire while the wire is not in contact with the base metal.
摘要翻译：公开了一种用于控制热丝焊接工艺的方法和装置，其中热丝的加热功率被自动调节到适当的值。通过过热将填充线熔接后的线加热功率设定为低于线熔点之前的加热功率的水平，并且线加热功率再次从设定值逐渐增加，直到线熔断为止过热通过重复该过程，热丝TIG焊接中的焊丝的熔融状态自动保持在最佳状态，而不需要焊接操作者的任何操作或他的直觉。此外，在填充线的通电期间，检测到线的过热的熔化瞬间，并且检测到的信号用于立即急剧地减少或暂停线电流，从而由于过热的熔化而引起的飞溅防止或大大降低线，并且防止飞溅物与电弧电极的粘附，从而允许长时间连续地进行热丝焊接操作。此外，使用脉冲电流来加热填充线，并且检测线的断电期间的线端电压，从而检测线是否与贱金属接触。如果导线不与基体金属接触，则在下一个脉冲施加期间不提供电流，从而防止电流从钨电极流向导线，同时电线不与基体金属接触。

摘要： A semi-automatic hot wier TIG (Tungsten Inert Gas) welding equipment comprising: a portable TIG arc torch; a portable filler wire feed torch; a hot wire switching power source for energizing the TIG arc torch, the filler wire feed torch and a base metal; a filler wire feeding device for feeding the wire to the wire feeding torch at a desired rate; a welding condition control device for controlling wire heating power so as to provide wire heating power commensurate to the wire feed rate; means for measuring the resistance value of the wire extension section between the terminal end of the wire and the terminal end of the filler wire feed torch; and means for controlling said filler wire feeding means to change the wire feed rate in response to the detected wire extension.According to the present invention, the welding operations are performed while the filler wire feed torch is held in one hand and the TIG arc torch is held in the other hand, so that the position where the arc and wire are inserted can be desireably adjusted. Adjustment of the welding conditions such as regulation of the welding arc current and adjustment of wire feed rate can be readily performed during welding.
