Description

Technical Field

[0001] The utility model belongs to the technical field of tungsten wire welding, and in particular relates to a special welding electrode for tungsten wire. Background Art

[0002] Tungsten wire electrodes have good heat resistance and can work stably in high temperature environments. They are suitable for occasions that require high temperature welding, such as aerospace, nuclear industry and other fields. Tungsten wires include: pure tungsten wires and tungsten wire alloys. This type of tungsten wire is used for photovoltaic silicon wafer cutting and carbon steel welding. In the prior art, when carbon steel is welded, the carbon steel welding electrode is prone to vibrate during the welding process, causing the weld to be skewed. As a result, the carbon steel welding electrode cannot remain stable due to the shaking, which reduces the success rate of carbon steel welding.

[0003] To this end, a tungsten wire welding device with convenient adjustment is disclosed with the announcement number "CN214444218U", which includes a base plate, a tungsten needle clamping plate arranged above the base plate and clamping the tungsten needle, a tungsten needle height adjustment device arranged on the base plate and adjusting the height of the tungsten needle clamping plate, a base plate rod arranged on the side of the base plate facing the tungsten needle clamping plate, a tungsten filament clamping plate arranged on the base plate rod and clamping the tungsten filament, and the tungsten needle height adjustment device includes a threaded rod rotatably connected to the base plate, a threaded rod threadedly connected to the threaded rod and detachable A driving block unloaded and connected to the tungsten needle clamping piece, a guide rod arranged on the bottom plate and passing through the driving block, an upper block rotatably connected to the threaded rod and fixedly connected to the guide rod, and a knob coaxially fixedly connected to the threaded rod are provided. The knob is provided so that the tungsten needle clamping piece can stably move in the vertical direction. At the same time, the tungsten needle clamping piece will not rotate along with the rotation of the threaded rod, so that the tungsten needle clamped and fixed by the tungsten needle clamping piece can easily be aligned and abutted with the tungsten filament, thereby improving the stability of the tungsten wire during welding.

[0004] However, for the above-mentioned tungsten wire welder with easy adjustment, although the tungsten needle pair should be inserted into the fine groove of the tungsten needle clamping plate so that the tungsten needle is clamped, and the length direction of the tungsten needle is parallel to the length direction of the base plate, and then the two ends of the arc-shaped tungsten filament are correspondingly inserted into the fine groove of the adjustment plate so that the tungsten filament is clamped, the following obvious defects still exist during use: when the fine groove in the tungsten wire clamp is used to clamp the tungsten wire, due to the fine groove's specific semicircular structure, the tungsten wire is easy to rotate unstably in the fine groove during the welding process, and the curled tungsten wire cannot be curled and welded.
