Settings for automatic arc welding
Process for the implementation of the welding machine is not enough to require a number of additional devices that form the pole with one or more arc automatic installation package for automatic arc welding. These devices and arrangements can be quite varied, depending on the configuration and dimensions of the product, the nature of manufacturing, etc.
First of all, it should be noted mechanisms move the arc along the seam, then the mechanisms for regulating and adjusting movements of the machine and products. Most vehicles are essential accessories for the installation, turning and moving products. In addition, the required electrical measuring and regulation equipment, hoses electric current, Flux equipment and various special unit. Requires a current source feeding the automatic installation of equipment related to it, most often it is - single phase welding transformer. settings for automatic arc welding can be classified according to various criteria, primarily in the form of welded joints, which can be straight, circular and curvilinear. Further, we can distinguish the universal set, suitable for welding, without alteration of various products or various forms of joints, and specialized installations for at least a wide range of products, or only one form of welded joints. High degree of universality usually have installation with welding tractors. The plants can be fixed, which summarizes articles to be welded, and mobile or portable, which is supplied to a fixed product, which is convenient and the only possible for bulky items (hulls). Especially the high portability of different welding tractors. Moving the arc can be as automatic movement, and the product, especially when welding circular joints; In automatic welding units are important devices to move and rotate the product to production welds in the most convenient position for welding, particularly for fillet welds "in the boat," or to rotate the product with a given uniform speed welding of circular joints. Arc welding machines are usually powered by current from the welding transformer. With a small enough standard welding current welding transformers, commonly used for manual arc welding. For larger currents required usually with submerged arc welding, use a powerful welding transformers, for 1000 and 2000 A. In the absence of power transformers can be used in parallel connection of several less powerful transformers. In automatic arc welding current is usually so large that it becomes increasingly characteristic of the arc, ie, its voltage increases with increasing current. This circumstance, and especially self-regulation of the arc at a constant feed rate of the electrode makes it possible to power an arc from the current sources with hard or increasing performance.
