Abstract
The utility model discloses a combined welding gun, which comprises an outer cover, wherein two welding protection connection heads and a plasma welding gun are fixed in the outer cover; and coils are arranged between the two welding protection connection heads and a gun body of the plasma welding gun and close to the gun body of the plasma welding gun. According to the welding gun, plasma arc welding and metal-inert gas welding (MIG) are compounded on the same welding gun; two near-distance welding modes are compounded by improving a nozzle of the plasma nozzle and additionally arranging a transverse magnetic field, so that stable electric arc is generated; excitation currents (such as direct current, pulse current and alternating current) with different directions and different magnitudes are applied to the magnetic poles of the coils, so that a welded joint fusion depth and a welded joint width are changed under a plasma arc, and a distance between the plasma arc and an MIG arc can be adjusted; and therefore, the welding gun can be adjusted according to welding requirements of various products.
Description
Technical field
The utility model relates to a kind of compound welding gun that consumable electrode noble gas protective (MIG) welding and plasma arc welding (PAW) are combined.
Background technology
The MIG solder technology has developed for many years, in commercial Application, is widely used.In the process of MIG welding, adopt self-feeding continuous consumption electrode, the gas in the shroud air.Electric energy is that metal transfer from sacrificial electrode is to the workpiece that is soldered.Transfer maybe be through one of following three kinds of basic models: (one) short circuit transmission, (two) shift spherical, (three) transfer of spraying.The spraying transmission mode is the most desirable, and under the environment of rich argon protective gas, spraying is a highly discrete drip, and it is powerful to the influence that is enough to overcome gravity to drip fast arc.The spray transmission mode is possible, if arc current is higher than a so-called transition current, diameter of wire and type of material depend on its value.Yet, high deposition rate, it is excessive that the transmission mode of typically spraying possibly produce the molten bath, can't be supported in the surface tension of vertical or built on stilts position.In addition, sedimentation rate, its amplification all become bigger welding current increase.This causes excessively filling metal electrode fusing and overconsumption.
It is reported that MIG weldering commonly used can realize the lockhole welding in PLASMA ARC WELDING (PAW) process. its major defect is a low speed.The speed of lockhole pattern is limited, the speed of scope from per minute 100mm to 600mm.
The speed of MIG is than faster, but welding penetration is limited, causes in the welding of slab, needing multiple welding.
The final welding quality of plasma welding is good, and speed of welding only limits to about 400mm/min usually.Under the situation of high-speed welding, plasma arc can produce towards the drift of the direction opposite with welding direction.
In the high-speed applications (PAW and MIG composite welding),, caused electric arc unstable before this, can't weld because the characteristic that plasma arc lags behind exists the risk that MIG electric arc blows plasma arc.
