Problems solved by technology

However, conventional hot wire TIG welding also has the following disadvantages: the current passing through the non-melting electrode is very limited, therefore, the filling amount of welding wire per unit time is small, and the welding efficiency is limited
Increasing the current through the welding wire during high-speed welding will increase the current through the workpiece at the same time, which may cause welding defects such as weld penetration and undercut

Abstract

The invention discloses a double consumable electrode and single arc bypass coupled compound welding system and a welding method thereof. The compound welding system comprises a first welding machine, a second welding machine, a first welding wire and a second welding wire, wherein anodes of the first and second welding machines are connected with the first welding wire; the first welding wire and a workpiece form an arc; a cathode of the first welding machine is connected with the workpiece; the cathode of the second welding machine is connected with the second welding wire; and the second welding wire and the workpiece do not form the arc. By adopting the technical scheme provided by the invention, the melting efficiency of the welding wires is greatly promoted, high-efficient welding is realized, a stable welding process is realized, the heat input quantity of base metal is controlled, the possibility of occurring a welding defect is reduced, and the compound welding system is beneficial to acquiring excellent welding quality.

Description

technical field [0001] The invention provides a new type of welding system and method, more specifically, it relates to a double melting electrode single arc bypass coupled hybrid welding, and relates to the technical field of welding engineering. Background technique [0002] Due to the limited current carrying capacity of the tungsten electrode in traditional TIG welding, the arc power is limited and the welding efficiency is also limited. Hot wire TIG welding can improve the deposition rate and welding speed of TIG welding. Hot wire TIG welding is to preheat the welding wire on the basis of ordinary TIG welding, so as to increase the heat input and increase the melting speed. The welding process of hot wire TIG filler welding is very stable and has good welding quality. However, conventional hot wire TIG welding also has the following disadvantages: the current passing through the non-melting electrode is very limited, therefore, the filling amount of welding wire per u...
