Problems solved by technology

For hot wire MIGA welding, according to the relevant patent materials, it is mainly arc heating wire, which has two main problems: first, the functional structure of arc heating wire is difficult to realize in the application of MIGA welding; second , the temperature of the arc heating wire is difficult to control precisely
[0005] The above-mentioned invention heats the working end (or close to the working section) of the welding wire by the heating structure of the welding wire, which greatly interferes with the gas metal shielded welding. In addition, the heating method adopts arc heating, which also greatly interferes with the arc itself. Moreover, From the perspective of welding conditions, it cannot be heated continuously during work, which may affect the adjustment of welding dry elongation

Embodiment Construction

[0024] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] see figure 1 , A hot wire MIG shielded welding device of the present invention includes a welding power source 9 , a welding torch 56 , and a welding wire power source 4 . One end of the welding power source is connected to the workpiece 8 and the other end is connected to the conductive tip 5 of the welding torch 56 to form a welding circuit B. The conductive wire 10 is fed by a wire feeding device (not shown in the figure), and its end is clamped by the conductive tip 5 of the welding torch 56 . One end of the welding wire power supply 4 is electrically connected to the welding wire 10 that does not enter the welding torch 56 through a conductive joint 1, and the other end is electrically connected to the conductive tip 5 of the welding torch 56 or its relevant parts (for example, the conductive seat 50, see appendix figure 2 ) connected to...

Abstract

The invention provides a hot wire consumable electrode gas-shielded welding device. The hot wire consumable electrode gas-shielded welding device comprises a welding power source, a welding gun and awelding wire power source, wherein the welding wire power source is slidably and electrically connected with a welding wire which does not enter the welding gun through a conductive contact so as to heat the welding wire. Due to the fact that the welding wire power source is arranged on the hot wire consumable electrode gas-shielded welding device for heating the welding wire which does not entrethe welding gun, a non-working end part of the welding wire or a part not close to a work segment of the welding wire is heated by adopting the above heating setup, the heating setup causes small interference to consumable electrode gas-shielded welding, and additionally a resistance / current heating mode for the welding wire is adopted, and also causes small interference to electric arcs in work of the hot wire consumable electrode gas-shielded welding device, and furthermore due to the fact that the conductive connector electrically connected with the welding wire is arranged, the hot wire consumable electrode gas-shielded welding device can uninterruptedly heat the wire in the work, and has no possibility to influence adjustment of welding dry extension.

Description

technical field [0001] The invention relates to a welding device, in particular to a submerged arc welding device with adjustable welding wire distribution. Background technique [0002] At present, how to increase the efficiency of welding wire deposition is one of the main problems for gas metal shielded welding. For hot wire MIGA welding, according to the relevant patent materials, it is mainly arc heating wire, which has two main problems: first, the functional structure of arc heating wire is difficult to realize in the application of MIGA welding; second , It is difficult to accurately control the temperature of the arc heating wire. [0003] The Chinese patent with the notification number CN101862886A discloses a hot wire melting electrode gas shielded welding method and its realization device, belonging to the field of welding technology. It solves the problem of low welding efficiency and poor welding quality in the existing welding method of metal gas shielded we...
