Description

C-shaped steel submerged arc welding device Technical Field The application relates to the technical field of welding equipment, in particular to a submerged arc welding device for C-shaped steel. Background C-shaped steel is used as a key component in the field of steel structures, and is widely applied to various industries such as various building engineering, bridge construction, mechanical manufacturing and the like by virtue of the unique sectional shape and good mechanical properties. The high-efficiency and high-quality C-shaped steel welding technology can effectively improve the overall strength and durability of the steel structure, reduce the later maintenance cost and has important significance for promoting the healthy development of related industries. In the prior art, the welding technology of the C-shaped steel mainly adopts two modes of manual arc welding and semi-automatic submerged arc welding. Manual arc welding relies on a welder to manually operate a welding rod, and the base metal and the welding rod are fused by high temperature generated by the arc. The method is simple to operate, low in equipment cost and suitable for small-sized projects and complex welding environments. However, the welding quality is greatly influenced by the experience and state of welders due to complete dependence on manual skills, the welding speed is low, the production efficiency is low, and the requirement of mass production is difficult to meet. The semi-automatic submerged arc welding is improved on the basis of manual arc welding, and the rail trolley drives the workpiece to be welded to move, so that the automation degree and the efficiency of welding are improved to a certain extent. However, the semiautomatic submerged arc welding technology has obvious defects, and the problem that the pressing force cannot be adjusted is particularly remarkable. When the welding wire feeding wheel faces welding wires with different diameters, the clamping distance is not adjustable, so that when the welding wires with small diameters are fed, the pressing force is too small, the welding wires are not fed stably, the welding joints are formed well, and when the welding wires with large diameters are fed, the pressing force is too large, the welding wires are possibly damaged, the service life of the welding wires is reduced, and finally the welding quality is influenced.
