Embodiment 1
[0020] Example 1: laminar flow plasma additive manufacturing forming ER83-G high-strength steel thin-walled boss parts, the chemical composition of ER83-G high-strength steel is shown in Table 1:
[0021] Table 1 Chemical composition of ER83-G high-strength steel welding wire
[0022]
[0023] Using laminar flow plasma additive manufacturing to form ER83-G high-strength steel thin-walled boss parts, the operation steps are as follows:
[0024] 1. Create a 3D model with SolidWorks software, such as figure 1 shown;
[0025] 2. Use the special software for laminar flow plasma additive manufacturing to slice the model. The forming trajectory has a total of 92 layers, including 62 layers for the square barrel (two layers of compensation layers are reserved), and 30 layers for the bezel;
[0026] 3. Set the forming parameters, the specific forming parameters are shown in Table 2;

Embodiment 2
[0031] Embodiment 2: laminar flow plasma additive manufacturing forming ER83-G high-strength steel round table piece, roughly the same as embodiment 1, the difference is that there are 22 layers of forming tracks, of which 12 layers are in the barrel part (two compensation layers are reserved). layer), the truss part has 10 layers, such as figure 2 shown; the specific forming parameters are shown in Table 3:

[0033]
[0034] The warm-up time is 20s.
Embodiment 3
[0035] Embodiment 3: laminar flow plasma additive manufacturing forming S960QL high-strength steel square barrel, the chemical composition of S960QL high-strength steel is shown in Table 4:
[0036] Table 4 Main chemical composition of S960QL high-strength steel
[0037]
[0038] Roughly the same as Example 2, the difference is that the model is sliced with the plasma 3D printing special software, and the forming track has a total of 42 layers (reserving two compensation layers), such as image 3 shown; the specific forming parameters are shown in Table 5:
[0039] Table 5 Specific parameters of S960QL high-strength steel square barrels formed by laminar flow plasma additive manufacturing
