The invention relates to a semi-automatic welding system for a flange of a transformer tank cover, which belongs to the technical field of a steel structural component welding device. The technical scheme is as follows: the semi-automatic welding system comprises a centering device, a driving device (3), a rotation shaft (4) and a welding gun clamping device, wherein the driving device (3) is fixedly arranged on the centering device, one end of the rotation shaft (4) is fixedly connected with the driving device (3), and the other end of the rotation shaft (4) is fixedly connected with the welding gun clamping device. According to the invention, the semi-automatic welding system for the flange of the transformer tank cover has the following benefits: the semi-automatic welding system is applicable to a flange with an either circular or square inner bore, and has the advantages of low cost, strong applicability, high production efficiency, good welding quality and convenience in operation and the like; and in addition, based on CO2 (Carbon Dioxide) gas protection as main equipment, the centering device, the driving device and the welding gun clamping device are increased to realize the semi-automatic welding of the large transformer tank cover with the flanges of different sizes, so that the equipment is capable of greatly reducing the labour intensity of workers and improving the quality of welded joints.
Description
technical field [0001] The invention relates to a semi-automatic welding system for the flange of a transformer oil tank cover, belonging to the technical field of welding devices for steel structural parts. Background technique [0002] The flange weld of the transformer oil tank cover is an important part of the oil tank welding. There are many welds and high strength in these parts. The quality requirements of the welds here are relatively strict. Due to the small rotation space of the tank cover, high-position welding is generally used, which makes welding difficult. Poor control can easily cause leakage. Automatic welding and semi-automatic welding can not only improve the quality of welds, but also reduce the labor intensity of workers and greatly improve labor efficiency. In the field of transformer oil tank welding, automatic welding and semi-automatic welding have been widely used in certain parts of welding, such as transformer oil tank reinforced iron welds. Due...
