[0002] Flange plate is suitable for connecting pipe component. In the production of large power iron tower, communication iron tower, flange plate will also be used, but due to the size of large iron tower is huge, so its pipe diameter is larger, and even the inner diameter can reach more than one meter, so the size of flange plate is also larger, and the thickness of flange plate is also thicker, generally more than 20mm. Such oversized flange plate cannot be directly processed due to size, generally a plurality of flange unit plates are cut from steel plate with corresponding thickness, and then the flange unit plates are sequentially spliced and fixed for welding. The welding equipment fully welds the welding groove between adjacent flange unit plates. Due to the thickness of the flange unit plate used for splicing the flange plate is thicker, the groove depth of the welding groove is also deeper, and the amount of welding material is also larger. When a large amount of welding material is accumulated in the welding groove, the adjacent flange unit plates will deform due to the high temperature of the welding material, and even the high-temperature molten welding material will escape from the bottom weld. If deformation occurs, the flange plate after welding needs to be reshaped. If the welding material escapes, the escaped welding material needs to be cut and polished later. The strength and hardness of such welding material are very high, which makes cutting and polishing very troublesome. Moreover, the cost of welding material used for such flange plate welding is relatively high, and the escaped welding material will also increase production cost and waste.
