The first step.
Make the internal structure of the sculpture based on the artistic structure of the sculpture. And the stainless steel skeleton is made according to the sculpture ratio. The specifications of the inner frame of the sculpture generally use 12#, 10#, 6.3# channel steel and 76mm*3mm, 50mm*3mm, 32mm*2.75mm pipes, 5*5 angle iron and so on. From bottom to top, from thick to thin, from dense to sparse, welded into a sculpture shape. Before making the internal skeleton of the sculpture, there are some things to pay attention to:
1. Check whether each incision is smooth. 2. The pipe groove should have groove gap as required. 3. All load-bearing frames are fully welded on both sides. 4. After the overall skeleton is completed, use anti-rust paint to complete the journey three times.
The second step.
Use channel steel, angle steel and other profile welding. Also, connect all the completed skeletons so that they are connected into a whole main skeleton. The advantage of this is that the entire huge structure can be combined and separated very well. It is easy to separate and install later. Attention should be paid when connecting:
1. The design of the shape and size of each sub-branch frame. Use 1:5 medium sample model to measure. 2. When all structures are connected. Need to follow from the bottom plane, take the vertical plane.
The third step.
Step-by-step forging and production of overall sculptural shapes. After completing the skeleton of the overall sculpture, we began to forge the outer surface of the sculpture according to the outer skeleton. When the outer surface of all large sculptures is made, the shape is often irregular. The outline shape of the main skeleton cannot be made exactly the same as the shape of the statue. The stainless steel outer wall cannot be directly hung on the main support. When making, our engineers have to consider the different expansion coefficients of stainless steel and restore the original form of the sculpture. After the body is forged. It is necessary to weld each part of the block together according to the requirements of the work. There are electric welding and argon arc welding. In stainless steel sculpture welding, Aongking Technology commonly uses tungsten arc welding to ensure excellent welding quality. Because it is not easy to conduct heat, the deformation of stainless steel is small.
The fourth step.
Treat and polish the surface of the sculpture. We generally use stainless steel carbon steel plates (#316 and #304). When polishing stainless steel, first, use a grinding wheel to smooth the welds and excess areas on the surface of the sculpture. Then, use a soft wheel (cloth wheel) for polishing and sanding. When polishing the surface of the sculpture, apply polishing paste to increase lubricity.
For this larger stainless steel sculpture modeling production. It is unrealistic to directly make the whole sculpture based on the proportion of the sculpture. We use the method of making the sculptures by dividing them into pieces and then combining all the pieces together to make the sculpture. This method requires accurate calculation of the frame size ratio. The seams and butt joints also need to be very precise. Otherwise, there will be differences and the expected production effect of the sculpture will not be achieved.
