To change the intensity of the electromagnetic field in the welding zone, the nut 2 is moved along the housing 1 and the spiral current lead 3, thereby changing the number of turns of the spiral current lead 3, through which the current passes. 3 il.

Description

The invention relates to electric arc welding with a control electromagnetic field and can be used for welding with consumable and non-consumable electrodes in the environment of shielding gases and submerged arc.

The aim of the invention is the provision of adjusting the intensity of the magnetic field by changing the number | q of turns of the spiral current supply "

In FIG. 1 shows a torch for welding with a consumable electrode, section; in Fig.2 - the same option; Fig. 3 torch for welding with a non-consumable 15 electrode.

The torch for magnetically controlled welding with a consumable electrode (Figs. 1 and 2) consists of a housing 1 on which a spiral current lead 3 is fastened by means of a nut 2 made of conductive material 3, through which a consumable electrode 4 passes through a guide channel. Current is supplied to the consumable electrode 4 through a removable 25 tip 5, which is mounted on a spiral conductor with a nut 6.

In Fig. 1, the insulation of the consumable electrode 4 from the spiral current lead-30 water 3 is carried out by a non-conductive material 7, for example, ceramic. A similar material 8 provides insulation of the turns 9 of the spiral current supply 3 from one another and 35 from the housing 1. '

In FIG. 2, the insulation of the melting electrode 4 from the spiral electrode, the current lead to water 3 is carried out by a conductive material 7, located between the 40 internal parts of the spiral current lead 3 and the conductive sleeve 10 ”The conductive material 4 provides isolation of the turns 9 of the spiral current lead 3 from one another and 45 from the housing 1.

The torch for welding with non-consumable electrode (Fig. H) consists of a housing 1 on which a spiral current lead 3 is fastened by means of a nut 2 made of conductive material 3. The non-consumable electrode 12 is fixed in the collet clamp I3 by means of a nut 6 in which the ring 14 is mounted made of non-conductive $$ conductive material. The insulation of the turns 9 of the spiral current supply 3 is carried out by a non-conductive material 15 ₀ A similar material 15 is implemented to isolate the spiral current supply from the housing 1,

The burner (FIG. 1) works as follows "

When passing through the spiral current lead 3, an electromagnetic field is created around it, the intensity of which at constant current is determined by the number of turns 9. To change the intensity of the electromagnetic field, nut 2 is moved but to the casing and spiral current lead 3, which allows you to change the number of turns. 9 of the spiral current supply 3 through which current flows. To replace the removable tip 5, unscrew the nut 6, remove the removable tip 5 and replace it with a new one, after which the nut 6 is again screwed onto the spiral current supply 3. The burner shown in FIG.

The burner (FIG. 3) works in the same way as the burner shown in FIG. 1.

To replace the non-consumable electrode 12, the nut 6 is unscrewed, the non-consumable electrode 12 is removed from the collet clamp 13 and another electrode is inserted "After which the nut 6 is screwed onto the spiral current lead 3 with a force that tightly presses the collet clamp 13 to the non-consumable electrode 12 and the spiral current lead 3"

The proposed torch allows its use not only for welding with a non-consumable electrode, but also for welding with a consumable electrode ”

The manufacture of a spiral current lead is not from scarce and expensive materials that are used for the manufacture of non-meltable electrodes, but from. less scarce and much cheaper materials, such as copper, and the unlimited service life of the spiral current supply can significantly reduce the consumption of materials used for the manufacture of non-consumable electrodes and thereby significantly reduce the cost of welding. The proposed torch also allows to increase the stability of the welding process.
