The invention discloses an 18-degree welding process for a wear-resistant belt of a drilling tool, and the 18-degree welding process adopts an 18-degree welding device for the wear-resistant belt of the drilling tool to implement. The 18-degree welding process for the wear-resistant belt of the drilling tool comprises a drilling tool jacking mechanism used for placing a drilling tool, a rotary machine head mounted on the drilling tool jacking mechanism, a three-claw chuck which is mounted on the rotary machine head and is used for clamping the drilling tool, a welding gun lifter, a welding gun wiggler mounted on the welding gun lifter and a welding gun mounted on the welding gun wiggler, wherein the drilling tool jacking mechanism is horizontally arranged; the welding gun wiggler and the horizontal plane are crossed to form an angle of 20-22 degrees so as to be mounted on the welding gun lifter in an inclined mode; the welding gun is perpendicular to the welding gun wiggler, so that the welding gun and the horizontal plane are in an inclined state; and a top-blowing pipe is arranged at the right side of the welding gun. The 18-degree welding process for the wear-resistant belt of the drilling tool disclosed by the invention is safer than a skid-mounted type welding device in the prior art, is better in operability, and can greatly improve production efficiency.
Description
technical field [0001] The invention relates to a welding process, in particular to an 18° welding process for a wear-resistant band of a drilling tool. Background technique [0002] The wear-resistant band of the drilling tool needs to be welded at 18°. After the high temperature in the welding process, the molten iron will flow to the lower part, which will cause the accumulation of molten iron in the lower weld. In order to solve this problem, the prior art generally adopts skid-mounted welding, such as figure 1 Let the drill pry up 18° to weld as shown. This method requires a complex prying device. Increased welding costs. figure 1 As shown in , 11 is the drilling tool jacking mechanism, 12 is the 18 degree hydraulic jacking mechanism, 13 is the rotary head, 14 is the three-jaw chuck, 15 is the drilling tool, 16 is the welding torch lifter, 17 is the welding torch swing Device, 18 is welding torch.
