1, Is the cutting material. The tool generally used is an electric scissors, which can cut a sheet of 2 mm or less, but the flatness is not good after cutting. There are also cutting machines, thick plates, thin plates can be cut, but can only cut the line, there is nothing to do when encountering the arc. To cut the stainless steel sheet into a flat and multi-shape, use a plasma cutter. Plasma cutting machines can use high plasma to cut metals that are difficult to cut with conventional oxygen cutting methods. Since the current and gas are passed into a special nozzle cooled by water, a strong compression arc is generated to form a very high temperature (more than 10,000 degrees) plasma flow, so that the cut stainless steel sheet is neat and not deformed. Note that the hand must be stable when cutting, otherwise the material will be cut. After the material has been cut, it is necessary to plan according to the shape required by the work. Do not leave any damage on the board surface, so as not to leave a flaw after polishing the work.
2. It is a method of making carbon steel sculptures and stainless steel sculptures. The carbon steel plate and the stainless steel plate are not knocked on the mold, but the material is cut out according to the different shapes of each part of the plaster model. According to the fluctuation of the plaster, the consciously tapping is performed, and the bend is bent. The place where the edge is knocked, can be beaten on any tangible solid object, and then the knocked stainless steel plate is taken to the mold to compare, the shape is correct and can be completely combined with the model, and then these scattered carbon steel plates, stainless steel The plates are welded from top to bottom, and each piece is adjusted to the mold. The texture of each stainless steel plate must be the same, which must be forged while being shaped. You can also forge the point and then cut it. When forging points, the round head of the hammer should be uniformly and regularly row-forged, and the width and the narrow distance should be the same. Do not know how to knock, otherwise it will destroy the overall sense of the sculpture.
3. After the body is forged correctly, they must be welded together according to the requirements of the work (with electric welding and argon arc welding). Electric welding should prepare electric welders, welding handles and welding rods. Due to the high level of light generated during welding, it is very irritating to the eyes, so wear a protective cover to avoid being damaged by strong light. With electric welding, the stainless steel plate has a large degree of thermal deformation, so some measures must be taken, such as spot welding or cooling while welding. Argon arc welding is superior to electric welding. It is a gas-shielded arc welding method that uses argon gas to protect the metal melted by the arc at the joint to avoid the harmful effects of oxygen and nitrogen in the air. According to the electrode materials used, argon arc welding can be divided into argon arc welding and non-melting arc welding or tungsten argon arc welding. In stainless steel sculpture welding, tungsten argon arc welding is commonly used, which can obtain excellent welding quality. . Because it is not easy to conduct heat, stainless steel is more deformed.
4, Carbon steel, stainless steel polishing First use the grinding wheel to make the welds and extra places of the production work, and then use a soft wheel (cloth wheel) for polishing, polishing the work with a polishing paste to increase lubrication, so that the work is thrown out Brighter, giving a good visual aesthetic.
5, The larger shape of the simple stainless steel sculpture, can also be used without welding. The steel frame can be directly made according to the proportion of the work, and the electric drill can be used to make a hole in the designed position, and the stainless steel plate can be fixed on the skeleton with rivets. This method requires that the scale of the skeleton be calculated very accurately, and the seams should be right, otherwise there will be differences that will not achieve the desired results.
