Stainless steel sculpture production process and welding precautions
We can see all kinds of sculptures everywhere in our lives. Among them, stainless steel sculpture is a relatively common one. For stainless steel sculptures, people may still have a little understanding of it. Let me introduce you to the production process and welding of stainless steel sculptures. Matters needing attention. 1. Process of making stainless steel sculpture 1. Make the shape first with a model: generally use foam or other materials of clay. 2. Draw each small piece of stainless steel according to the shape, and try not to be too large. 3. According to the small cast iron Cut out the stainless steel plate from the piece, and then beat it to have a curvature. 4. Then weld these small pieces. 5. Weld, polish, polish, and finish the ground. Different colors can also be used for the sculpture according to needs. 2. Stainless steel sculpture Welding precautions 1. Stainless steel electrodes usually have two types: titanium calcium type and low hydrogen type. Welding current uses DC power as much as possible, which is beneficial to overcome the redness and shallow penetration of the electrode. 2. When the stainless steel sculpture is welded, the stainless steel electrode should be maintained Drying. In order to prevent defects such as cracks, pits, pores, etc., the titanium-calcium type coating is dried at 150-250℃ for 1h before welding, and the low-hydrogen type coating is dried at 200-300℃ for 1h before welding. 3. Used Welding joints for welding stainless steel sculptures need to be cleaned, and at the same time, prevent the welding rod from getting oil and other dirt, so as not to increase the carbon content of the weld and affect the welding quality. 4. In order to prevent corrosion caused by heating, the welding current should not be too large. It is about 20% lower than carbon steel electrode, the arc should not be too long, the interlayer is fast cooling, and narrow pass welding is suitable. Arc plate is used to start the arc. 6. Short arc welding should be used as much as possible. The arc length is generally 2-3mm. If the arc is too long, it is easy to cause thermal cracks. The above content is brought to you by the Beijing stainless steel sculpture manufacturer about the stainless steel sculpture production process and The introduction of its welding precautions, I hope it can help you.
