Embodiment Construction

[0022] The referenced drawings are only used to illustrate preferred embodiments of the present invention, and are not intended to limit the present invention. Now refer to figure 1 with figure 2 , it can be seen that the reference numeral 100 represents the twin-wire welding torch assembly of the twin-wire gas shielded welding equipment according to the present invention.

[0023] figure 1 with figure 2 The illustrated twin wire torch assembly 100 includes two separate and parallel welding wire conduits 1 , two power cord connectors 4 , shielding gas nozzle 10 and two contact tips 12 . Although not in figure 1 with 2 As shown in , the twin-wire gas shielded welding equipment also has a wire feeding unit, which is used to independently provide two independent electrode welding wires to the welding torch, and the two welding wires are fed through the two welding wire conduits 1 The welding wire is driven to the respective contact tip 12 .

[0024] In one embodiment, th...

Abstract

The utility model relates to a double-wire MIG shielded welding equipment, which has an adjustable welding torch assembly for welding wire spacing. The twin-wire welding torch assembly has a welding wire spacing adjustment mechanism. With the help of the welding wire spacing adjustment, the welding torch assembly can be used for a non-synchronously controlled droplet transfer welding process. The welding wires remain parallel before, during and after adjustment of the welding wire spacing.

Description

technical field [0001] The present invention relates to gas metal arc welding (GMAW), and more particularly to a torch for use with gas metal arc welding equipment employing two welding wires as electrodes and filler to apply metal to a single molten pool. The invention also relates to a metal gas shielded welding method using the welding equipment. Background technique [0002] GMAW (gas metal arc welding) welding is a commonly used industrial welding process mainly because of its advantages in terms of versatility, welding speed, and relatively easy adaptation to automation. In the single wire GMAW process, a single continuous and consumable electrode wire and shielding gas are supplied through the welding torch. [0003] To achieve higher welding speeds, twin wire GMAW welding equipment and its process have been developed, which employ two electrically insulated wire electrodes to combine two arcs in one weld pool. In the double wire gas shielded welding process, two wi...
