Sculpture has existed for centuries; However, the welded steel sculpture is a fairly new concept, with the earliest recorded welding sculpture production time of about 1932. It is very interesting to make sculpture and make a great garden function. What you need: Welder/oxygen/acetylene set leather welded gloves closed shoes ( Leather is best) Welder helmet scrap pair (long shirt and trousers) Hold sculpture) Clamp wire brush hammer tin shear angle grinder (optional) The first thing you need to do is choose a theme or something to make a sculpture. It can be an animal, a person, or an object. This should be something that is easy to create. Get some pictures from the Internet of your item and draw it from 3 angles ( Top, side and front). The next task is to obtain a welder or an oxygen/acetylene device. Most hardware stores will have welding machines and welding rods, but you have to go to the store to buy an oxygen/acetylene suit. Since the Arc will blind you, you have to wear a welder helmet or goggles! Your welder and brush should come with a shard hammer. The angle grinder is optional, but helps to shorten the time and cut the steel more quickly. If you don\'t have a angle grinder, the Hacksaw is enough. You can cut the sheet metal that makes up most of your sculpture with tinsnips. You can ask businesses that process scrap metal recycling to sell you some scrap. Before you start welding on your sculpture, it\'s a good idea for you to practice a piece of scrap. You should clean the entire welding surface before starting welding. Step: 3. 1. 1 understand the working principle of arc welderAn arc welding machine is to pass the current through the electrode, the electrode jumps to the ground metal through the air gap, and because of the high current and the tip of the heat melting Rod, therefore, welding surface. Step: 3. 1. The easiest way to prepare the welded surface to clean up the welded surface is to use the angle grinder. But if you don\'t, just clean the gap with sandpaper and brush. Remove paint and rust. Step: 3. 1. 3 set up your welder you have to set your welder to the correct number of amps so that you can make high quality welds. The machine is set too high, it will only cause a lot of splashing welds and melt the ground metal too much. The machine that is too low will make the electrode stick to the ground metal and will not provide a highly penetrating weld. The height you need to set up your machine depends on what welding electrodes you have. ( Guide at the bottom of the document)Step: 3. 1. 3 tap the arcTo to start the arc, you have to hit the bar like you hit the pool, the bar has to scrape along the ground metal. Soon you will see an arc of light, and in order to continue this arc of light, you will have to have an air gap between the rod and the ground metal, so generate enough heat to melt the rod and melt the metal. Step: 3. 1. When you weld, you have to move the electrode to make the beads, which can be formed by moving the rod in different modes. Some popular patterns are; New Moon and zigzag. Step: 3. 1. 5 clear slagAfter you finish a bead and you will have a layer of slag and you can cut it off with a shard hammer and remove the carbon from the weld using a brush. IMPORTANT! : After each weld, before starting another weld, remove and clean the weld first. Step: 3. 1. 6 Test the welding quality depends on which part of the sculpture you weld, you have to test the strength of it, to do this, you have to move it by hand, if you can\'t break it, it\'s strong enough. Since it\'s only for the purpose of the decoration, you don\'t have to make it super powerful. Step: 3. 1. If the metal, electrode or gloves are wet, do not Weld by arc welding machine. This can lead to electric shock. Don\'t touch your workpiece for at least 5 minutes without gloves, as it will last for a long time. Arc welding causes hot metal debris to \"explode\" in each direction, ensuring that there is no flammable material around. Step: 3. 2. 1 understand the oxygen/acetylene setAn oxygen/acetylene group ( Or short for oxygen sleeve) Combined work of 2 gases ( Oxygen and acetylene) Place the different mixture in the hose and then come out of the welding nozzle, which must be mitigated by the forward. You can get the welding nozzle from 000 ( Thin metal welding)to 3 ( Thick metal welding). Step: 3. 2. What you need, what you need; Each gas cylinder, acetylene gas cylinder, regulator and hose, welding torch with welding nozzle (around 000) Welding goggles and strikers ( Light the torch)Step: 3. 2. 3 The amount of gas you have to adjust when welding with an oxygen device. To do this, you need to use the faucet near the gas cylinder. First, you open the acetylene cylinder by turning the faucet. Set the acetylene regulator to 5 psi, open the needle valve on the torch and let the acetylene escape. Adjust the regulator until the acetylene is in a solid state of 5 psi and then close the pin valve. Fully open the main oxygen valve and then adjust the oxygen regulator to 10 psi. Let it stabilize and continue to adjust it to maintain 10 psi and close the needle valve for oxygen. Open the acetylene valve about. 1/8 turn, then ignite the acetylene gas with the striker. Step: 3. 2. 4 Prepare the flame to continue to release acetylene until the flame is about to leave the tip of the torch, slowly turn on the oxygen pin and set it to a neutral flame. In a neutral flame, the ratio of oxygen to acetylene is equal. The Blue part in the middle will be merged into the blue part in white, which is a neutral flame. Step: 3. 2. Weld with oxygen when you are ready for the flame, ready for your surface, and have your safety equipment ready for welding. You must use the middle blue part of the flame to Weld; This part must touch your artifact. Continue to heat the two surfaces of the metal until a pool is formed in both parts. If this does not happen, the pool should be merged into a pool to continue heating the unmelted part. Once this happens, you have to use a flame to stir the two pools together, which will form a weld. After the welding is completed, first close the oxygen pin valve and then close the acetylene valve. Step: 3. 2. Because the oxygen group uses oxygen, it is very dangerous to ignite things. Oxygen accelerates the burning process and can be fatal. When welded with oxygen Group, the workpiece can maintain heat for a long time due to the heat generated by welding. This can be dangerous if you don\'t have leather gloves. Reverse fire: reverse fire will cause the flame to shoot to the nozzle and stop at the lightning arrester; This will cause a loud noise. Flash back: flash back is like a reverse fire, but it can be carried into the tube of the tank. First, the oxygen torch should be closed, then the acetylene torch valve should be closed, followed by the oxygen tank valve, and finally the acetylene tank valve. When welding, you may encounter steel pools or droplets that fall off the workpiece. This will cause a sensation and may send hot pieces everywhere. Make sure there are no flammable items around. Before you start welding the sculpture, you have to create a solid foundation for the smaller parts. This can be done by bending some of the wires into the rough shape of the sculpture, and the 5/16ths rod or 3mm will be done. Weld it to a base such as a tripod or a steel platform. This part you have to use small pieces of steel to weld the body, which will build the structure and give it the overall shape. You may have to cut parts in special shapes and bend them into \"panels \". \"This can be done by hitting the ball in the secondary water with a ball hammer or using a trolley. The next part is welded on smaller parts; These may be random scrap steel such as wrenches, bolts, nuts, screws, pipes, grids, and rods. Because you don\'t repeat it, it will have a better effect. In this step you will make \"add-ons”. These are the most detailed parts, such as the head of the animal, the claws of the bird, or the wings, etc. For a bird, you might want to get a piece of scrap that is close to the shape, just weld it on extra parts like steel pipes. Small pieces can be used to define the texture of your sculpture. In this step, you take a step back after the meeting and appreciate what you have created. This will give you a chance to perfect and improve your sculpture. If you need to cut something off, you can use a Angle grinder or a hacksaw. When you finish welding the sculpture, it\'s time to decide what you want it to look like. Some of the popular finishes are: rusty steel paint face hammer-tone paint face you will have a good one once painted Homemade sculptures for garden or home display. -- For electrode amps 05/02/12-chart- Used to help complete the 05/02/12 welding steps edited by Elocina on September 23, 2011- Revised history for oxygen soldering process 05/02/12: Ver 1. 0 --5/97 --Steve Johnson -- Original text 1. 1 --6/97 -- Brian Cooper Ryder- Format, revision, and additional features 1. 2 --10/01 -- Catherine kutchbeck- Minor modifications. -- Danger for welding (gas and arc)05/02/12 -- For neutral flame 07/02/12-picture- Photo 06/02/12 of the oxygen torch suit \"how- \"Uploaded to as part of SACE\'s 12-year research program \".
