stone sculpture are very common in many squares and parks in our lives. There are many materials for these stone sculpture, and everyone loves these stone sculpture. There is a kind of Marble Sculpting that has attracted everyone's attention in recent years, and people are also very interested in its welding process, hoping to learn more about the welding of Marble Sculpting.
In recent years, with the continuous change of people's aesthetics, the
stone carving industry has an excellent development prospect. Now we can often find stone sculpture in every corner around us. Marble Sculpting is one of the more common stone sculpture now, so compared with traditional stone sculpture, what details do we need to pay attention to when welding?
1. There are usually two types of stainless steel electrodes: titanium-calcium type and low-hydrogen type. The welding current adopts DC power supply as much as possible, which is beneficial to overcome the redness and shallow penetration of the welding rod.
2. When welding marble sculptures, the stainless steel electrodes should be kept dry. In order to prevent defects such as cracks, pits, and pores, the titanium-calcium type coating is dried at 150-250 °C for 1 hour before welding, and the low-hydrogen type coating is dried at 200-300 °C for 1 hour before welding.
3. The welding joints used for welding Marble Sculpting need to be cleaned, and at the same time prevent the welding rods from being stained with 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, generally about 20% lower than that of carbon steel electrodes, the arc should not be too long, and the layers should be cooled quickly.
5. When welding Marble Sculpting, the arc cannot be struck at the non-welding part, and the arc strike plate of the same material as the weldment should be used to strike 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, thermal cracks will easily occur.
Pay attention to these problems in the process of welding Marble Sculpting, you can ensure the welding quality of Marble Sculpting, and you don't have to worry about the quality of Marble Sculpting.
