Description
Technical field
The invention belongs to increases material manufacturing technology field, and in particular to a kind of double tungsten electrode noble gas protecting electricity of stainless steel component
Arc (Gas Tungsten Arc, GTA) aids in consumable electrode gas-arc electric arc (Gas Metal Arc, GMA) increasing material manufacturing method
And system.
Background technology
Stainless steel due to its excellent high temperature resistant and corrosion resistance, thus be widely used in aviation, track traffic, automobile,
The fields such as building.At present, the traditional manufacturing process of stainless steel component includes casting, forging and machining, casting method shaping
Component mechanical performance it is not enough, forging method is by element structure complexity and production-scale limitation, machining process material
Expect that utilization rate is low, the manufacturing cycle is long.Therefore, the above method is all difficult to the flexibility for meeting high-performance labyrinth stainless steel component
Manufacture.In recent years, metal increases material manufacturing technology is gradually risen.Increasing material manufacturing is that one kind is based on discrete-accumulation principle, from the bottom to top
Successively accumulate with the manufacturing technology of forming three-dimensional entity.Compared with above-mentioned traditional manufacturing technology, technologic material loss is low, shaping
Efficiency high, eliminates cumbersome manufacturing procedure, it is adaptable to the flexibility manufacture of complex component, has in stainless steel component manufacture
Good application prospect.
Metal increases material manufacturing technology is thermal source frequently with laser or electric arc.Compared with electric arc, laser equipment cost is high, from drop
From the point of view of low manufacturing cost, it is advisable with electric arc as thermal source.At present, it is adaptable to which the electric arc thermal source of stainless steel increasing material manufacturing is main
There are GTA and GMA.It is small that GTA forming accuracies are high, forming process is splashed, but forming efficiency is low, by contrast, GMA forming efficiency
Height, is adapted to the direct manufacture of medium-and-large-sized metal parts.But GMA forming currents are big, heat input is high, arc force is big, molten drop is to molten
Pond percussion is strong, causes molten bath to cave in and is distorted with shaping, reduces forming quality.
The thermal conductivity of stainless steel is low, about 1/3rd of carbon steel, during stainless steel GMA increasing material manufacturings, heat accumulation
It is even more serious, molten bath cave in shaping distort the problems such as it is very prominent, metalwork shaping after showed forming accuracy, surface matter
Amount is also unsatisfactory with mechanical property.In addition, serious heat accumulation increases the interlayer cooling stand-by period, shaping is greatly reduced
Efficiency.Therefore, it is necessary to be improved stainless steel GMA increasing material manufacturing methods to improve its forming quality and forming efficiency；Together
When, while stainless steel component forming efficiency is kept, it is reduced as much as possible and shapes heat input, then is a kind of feasible improvement
Thinking.
The content of the invention
The invention aims to solve, stainless steel component heat input during GMA increasing material manufacturings is big, heat accumulation is tight
There is provided a kind of double GTA auxiliary GMA increasing material manufacturings of stainless steel component for the problems such as shape stability and forming quality difference caused by weight
Method and system.
For achieving the above object, technical solution of the present invention is as follows：
A kind of double GTA auxiliary GMA increasing material manufacturing methods of stainless steel component, a set of adopt is respectively mounted in the GMA rifles left and right sides
With the GTA rifles of independent GTA power supplys, double GTA auxiliary GMA rifles are constituted, GMA rifles connection GMA positive sources, left side GTA power supplys are just
