The emergence of welding robots has greatly liberated a certain amount of labor, making the welding process easier, because the welding robot is equipped with an automated wire feeding system, including wire feeding, wire feeding hose, welding wire reel and other components. Therefore, the welding wire can be sent to the designated position through the perfect configuration, in one step. The wire feeding system of the welding robot can feed wire in three different ways, namely push wire, wire drawing and push wire feeding.
1. Push wire feeding method: This structure is relatively simple, light, and easy to operate and maintain; its disadvantage is that the resistance of the welding wire is relatively large. As the wire feeding hose is lengthened, the wire feeding stability becomes worse. . Therefore, this wire feeding method is usually used in semi-automatic molten gas shielded welding with a wire diameter of 2.0mm and a wire feeding hose length of 5m.
2. Wire-drawing wire feeding method: There are two methods in this way. One is to separate the wire reel and the welding torch so that they are connected through a wire feeding hose; the other is to install the wire reel directly on the welding torch; and these two Both are suitable for thin wire semi-automatic melting and gas shielded welding. The diameter of welding wire is less than or equal to 0.8mm, and the wire feeding is relatively stable.
3. Push-draw wire feeding method: This kind of wire feeding system has both a wire pushing machine and a wire drawing machine. The wire pushing is the main driving force. The wire drawing is to straighten the welding wire. Although its wire feeding hose can be extended to 10m, However, due to its complex structure, it is not used much in practice.
Wire feeding is an indispensable part of the welding process, so when choosing a welding robot, this aspect should also be considered, and the appropriate wire feeding method should be selected.
