Description
Technical Field
The utility model belongs to the technical field of aluminum alloy welding, concretely relates to TIG-CMT hybrid welding aluminum alloy device.
Background
Tungsten Inert Gas (TIG) is the most widely used gas-shielded arc welding process for joining aluminum and its alloys because of its superior flexibility and economy. TIG welding is a high quality, stable process with low spatter, good weld appearance, etc., but has problems such as low welding speed, incomplete penetration and lack of deposited metal. The Cold Metal Transfer (CMT) process is an improved MIG welding process based on a short circuit transfer process, and compared to the conventional MIG process, the droplet separation mode of the CMT process is not assisted by electromagnetic forces and thus spatter can be reduced. However, the low heat input in the CMT welding process can cause insufficient penetration of the aluminum alloy, discontinuous welding seams and insufficient local filling, larger penetration can be obtained by increasing the CMT current, but the stable short circuit transition of the CMT can not be ensured under higher current (more than 100A).
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that the current situation to prior art provides a TIG-CMT hybrid welding aluminum alloy device, can effectively solve the not enough, intermittent problem of welding seam of penetration.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: the TIG-CMT composite welding aluminum alloy device is characterized by comprising a tungsten inert gas shielded welding machine, a tungsten inert gas shielded welding gun, a cold metal transfer welding machine and a cold metal transfer welding gun, wherein the tungsten inert gas shielded welding machine is connected with the tungsten inert gas shielded welding gun, the cold metal transfer welding machine is connected with the cold metal transfer welding gun, the tungsten inert gas shielded welding gun preheats a base metal at the front end in advance, and the cold metal transfer welding gun fills a welding seam at the rear end.
In the TIG-CMT hybrid welding aluminum alloy device, the TIG inert gas shielded welding machine is an AC welding machine, the type is TIG Magic Wave4000, and the frequency is 60 Hz; the welder for cold metal transfer welding is a direct current welder with the model of Advanced CMT 4000R.
In the TIG-CMT hybrid welding aluminum alloy device, the shielding gas of the TIG-CMT welding gun and the welding gun for cold metal transfer welding is 99% pure argon.
Compared with the prior art, the utility model has the advantages of the welding speed of tungsten inert gas shielded welding (TIG) is low, and the penetration is incomplete and lack the cladding metal. Lower heat input during Cold Metal Transfer (CMT) welding results in insufficient penetration of the aluminum alloy, discontinuous weld and insufficient local filling. The large penetration can be obtained by increasing the CMT current, but the stable short circuit transition of the CMT can not be ensured under the high current (more than 100A), and the problems of insufficient penetration, splashing, insufficient deposited metal filling and the like in the aluminum alloy welding process can be effectively solved.
