Abstract

The invention provides vacuum welding equipment capable of automatically detecting a weld joint and a using method of the vacuum welding equipment. The vacuum welding equipment comprises a vacuum device, a welding vacuum chamber, a feeding vacuum chamber, an electron beam welding device, a welding worktable, an argon arc welding device, a nitrogen generation device and a weld joint detecting device; the welding vacuum chamber and the feeding vacuum chamber are provided with a piston sealing plate and a lifting sealing plate correspondingly; the electron beam welding device is arranged on the piston sealing plate, and the welding worktable can be overturned by 180 degrees and rotated by 360 degrees; the argon arc welding device is mounted on the piston sealing plate in a replaceable mode, and the nitrogen generation device can provide liquid nitrogen for a welding gun and a weldment for cooling; and the weld joint detecting device is arranged at the bottom of a feeding conveying belt. Adetecting frame is arranged to be of a semi-arc structure and can rotate, detection through a probe on the detecting frame is more thorough, when the weldment is transferred out from the equipment, the quality of the weld joint of the weldment can be quickly, conveniently and accurately detected, and the production efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of vacuum welding, and relates to a vacuum welding equipment capable of automatically detecting welding seams and a use method thereof. Background technique [0002] In the existing welding equipment, there are many technologies such as explosive welding and vacuum welding.

[0002] In the existing welding equipment, there are many technologies such as explosive welding and vacuum welding. Among them, vacuum electron beam welding is the welding of materials in a vacuum environment. Electron beams can weld different metals and alloy materials, especially high refractory metals. Welding, and the welding precision is high, the efficiency of welding large and thick parts is higher, the welded joints are of high purity, the weld seam is pure, smooth, mirror-like, and free of oxidation and other defects; but at present, due to the long vacuuming time of large-scale vacuum electron beam welding, about It takes 10-15 minutes, and repeated vacuuming is required for each welding, which affects the production efficiency of the equipment. Especially when welding small parts, continuous welding cannot be carried out, and the vacuuming time seriously affects production efficiency; in addition, in the existing welding process, there are It is necessary to switch to use argon arc welding equipment for alternate welding operations. During the welding process, a large amount of smoke is generated, which seriously affects the welding quality of the welded parts and the health of personnel. At the same time, the weld quality cannot be automatically detected after welding, which affects production efficiency.
