Embodiment Construction

[0027] In order to further understand the content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0028] Such as figure 1 with figure 2As shown, the present embodiment provides a magnetically controlled K-TIG welding torch based on a permanent magnet array. A magnetically controlled device is installed on the lower edge of the copper sleeve of the welding torch head 1. The magnetically controlled device includes a cross fixing plate 2, a magnet fixed Slot 3, permanent magnet 4 and magnet fixing block 5.

[0029] The cross fixing plate 2 is a cross-shaped plate structure with four supporting plates, and its center position is provided with a circular welding torch fixing hole 201 according to the size of the welding torch head 1. The proper position of the torch head 1, and directly or through the gasket material is fixed on the lower edge of the...

Abstract

The invention belongs to the technical field of K-TIG welding guns, and discloses a magnetron K-TIG welding gun based on a permanent magnet array. A cross fixed plate is mounted on the lower edge of a copper sleeve of a gun head of the welding gun; magnet fixed grooves are respectively formed in the lower parts of four support plates of the cross fixed plate; a certain quantity of permanent magnets are put in the magnet fixed grooves; the permanent magnets are limited by baffle plates of the magnet fixed grooves and magnet fixed blocks arranged in the magnet fixed grooves; and the permanent magnets in the four magnet fixed grooves are arranged in a manner of N poles to N poles and S poles to S poles, and are symmetrically and equivalently arranged. The permanent magnets with controllable number are used for replacing electromagnets to form an annular magnetic field to compress K-TIG welding arc; the device is simplified under the precondition of guaranteeing controllable magnetic field; the restraint effect and the penetrating power of the arc are improved; the heat source characteristics of the welding arc are improved; the stability is improved; and the numbers of the permanent magnets in all directions are adjusted to obtain needed process windows in a targeted manner to realize high efficiency of the TIC welding.

Description

technical field [0001] The invention belongs to the technical field of a K-TIG welding torch, and in particular relates to a magnetically controlled K-TIG welding torch which increases an adjustable magnetic field and shrinks an arc column. Background technique [0002] TIG welding can achieve high-quality welding, but the existing TIG welding arc energy density is low, which limits its welding efficiency. Based on the traditional TIG welding gun, the water-cooled tungsten electrode produces the cathode shrinkage effect, and with the large welding current, a new perforation welding process method is obtained, which is called CF-TIG welding or K-TIG welding; the principle lies in: TIG welding process , the welding arc is established between the tungsten electrode (cathode) and the workpiece molten pool (anode), the adhesion form between the arc and the cathode is mainly determined by the thermionic emission behavior of the cathode, and the thermionic emission of the cathode m...
