Embodiment 1

[0043] Use the welding method of aluminum alloy automatic MIG welding double-body walking equipment to weld the 5083 aluminum alloy flat plate with a plate thickness of 20mm and a specification of 20×800×5000mm. The welding process adopts full automatic welding, and the welding wire is ER5183 aluminum welding wire with a diameter of Φ1. .6mm.

[0044] The blunt edge thickness h of the groove is 6 mm, the assembly gap p ranges from 0 to 2 mm, and the groove angle α is 60 degrees. For joint groove form, see Figure 6 shown.

[0045] The track setting adopts a flexible track that can be attached to the board surface and is flat welded.

[0046] Such as Figure 7 As shown, the upper surface in the figure is the front side, and the lower surface is the reverse side.

[0047] The specific welding technical parameters are shown in Table 1:

Embodiment 2

[0053] Use the welding method of aluminum alloy automatic MIG welding double-body walking equipment to weld the 5083 aluminum alloy arc-shaped plate with a plate thickness of 40mm and a specification of 40×1300×9000mm. Φ2.4mm.

[0054] The blunt edge thickness h of the groove is 6mm, the assembly gap p ranges from 0 to 3mm, and the groove angles α and β are 80° and 100° respectively. For joints and grooves, see Figure 4 shown.

[0055] The track setting adopts a flexible track that can be attached to the board surface and is flat welded.

[0056] Such as Figure 5 As shown in the figure, the upper surface is convex and the lower surface is concave.

[0057] Select the convex surface for welding, and the welding torch moves forward along the weld seam without swinging.

[0058] Select the concave surface for welding, and the welding torch swings forward perpendicular to the direction of the welding seam.

[0059] The specific welding technical parameters are shown in Tab...

Abstract

The invention discloses a double-type aluminum alloy walking arrangement for automatic MIG welding and a welding method thereof. The arrangement comprises a wire feeder walking trolley, a welding gunwalking trolley and a digital semi-automatic MIG welder; the wire feeder walking trolley is arranged on a wire feeding trolley rail and carries a wire feeder, the welding gun walking trolley is arranged on a welding gun trolley rail and fixedly provided with an oscillator, the oscillator is fixedly provided with a welding gun, the welding gun is connected with the wire feeder by a welding gun cable, and a signal wire is connected between the welding gun walking trolley and the wire feeder; and the MIG welder is connected with the wire feeder by a trunk cable. The walking arrangement can meet the production requirements of manual semi-automatic welding and can also fulfill the requirements of full-automatic welding at a flat welding position. The walking arrangement can reach the welding quality and welding efficiency equivalent to those of full-automatic welders, and has the advantages of low cost, applicable popularization and the like.

Description

technical field [0001] The invention belongs to the field of welding technology, and more specifically relates to a flexible welding method, which can not only meet the production requirements of manual semi-automatic welding, but also meet the requirements of fully automatic welding in the flat welding position, and can be used for curved aluminum alloys. An aluminum alloy automatic MIG welding two-body walking equipment and its welding method for effective welding of test plates and saving investment. Background technique [0002] In recent years, with the development of information technology, various well-known welding equipment manufacturers have successively developed a variety of digital MIG welding machines, such as the TPS series of Fronius Company in Austria, the Pro series of Kemppi Company in Finland and the TRI series of SAF Company in France, etc. . These welding machines can achieve very good welding quality on aluminum and aluminum alloys. However, most of ...
