Problems solved by technology

Therefore, it is difficult to popularize and use it in large quantities. It is only used in automatic arc welding and cannot be used in semi-automatic arc welding.
[0005] This shows that above-mentioned existing rotary arc welding obviously still has inconvenience and defective in the structure of method, equipment and use, needs further improvement

Embodiment Construction

[0031] In order to further explain the technical means and effects that the present invention takes to achieve the intended purpose of the invention, the specific implementation, structure, characteristics and features of the multi-wire rotary arc welding proposed according to the present invention will be described below in conjunction with the accompanying drawings and preferred embodiments. Efficacy, detailed as follows.

[0032] see figure 2 As shown, the multi-wire rotary arc welding of the preferred embodiment of the present invention includes a welding power source 1, a welding wire 2, and a wire feeding device 3. The welding wire 2 is a multi-strand welding wire, and at least one strand of welding wire is tightly wound around the rest of the welding wire in a helical manner. The outer layer of the welding wire (such as image 3 , Figure 4shown), or the outer layer of the central welding wire, under the action of the welding power supply, an arc is formed between al...

Abstract

The invention relates to an arc welding, in particular to a multi-wire rotating arc welding, which is a rotating arc welding utilizing welding wires wound in a certain helical angle, automatically formed in the welding process and having stirring effects on a molten bath. The multi-wire rotating arc welding not only improves welding melting efficiency but also enables welding line metal alloy to be even in component, and grain refinement is achieved.

Description

technical field [0001] The invention relates to an arc welding, in particular to a multi-wire rotary arc welding. It uses the welding wire wound at a certain helix angle to automatically form a rotating arc that has a stirring effect on the molten pool during the arc welding process, which not only improves the welding deposition efficiency, but also makes the weld metal alloy composition uniform and the grains finer. Background technique [0002] There are two types of existing rotary arc welding, one is the rotary arc welding proposed by the former Soviet Union in the 1950s, which refers to the formation of an arc between two joint end faces, and the arc rotates at a high speed under the action of a magnetic field to make the joint end faces It is a high-efficiency welding method that is heated and then connected by upsetting. This kind of rotary arc welding belongs to flash butt welding in contact welding, and does not belong to the category of arc welding. It is mainly ...
