MIG welding is a kind of arc welding that uses a metal electrode to match the alloy of the work section and an inert gas to transfer oxygen from the weld region. MIG welding is the most suitable welding technique for aluminum, with the exception of particularly thin aluminum sheeting. MIG welding is a kind of arc welding that uses a metal electrode to match the alloy of the work section and an inert gas to transfer oxygen from the weld region. MIG welding is the most suitable welding technique for aluminum, with the exception of particularly thin aluminum sheeting. MIG welding aluminum needs more practice and skill than welding steel. Prepare the surfaces of the aluminum elements by cleaning the exterior with a solvent, then using the wire brush to remove any oxides. This removes any constituent part and impurities and prevents them from becoming trapped in the weld. Clutch the electrode at a 10- to 15-degree angle from the vertical, sharp toward the way of the ppr pipe cutter . It is significant to use the push process when MIG welding aluminum. The pull process would prevent the argon gas from sufficiently covering the weld, resulting in an inconsistent weld. Make a pool of molten aluminum with the electrode and gradually push the electrode forward. Regulate the voltage of the welding machine to get spray transfer of the aluminum electrode. In spray transfer, the electrode release small droplets of the metal into the weld. This will results in a smooth weld and the droplets do not get in the way with the electrode arc. , ...ادامه مطلب

Oxy-Acetylene Welding Equipment Welding with the use of gas dates back to the middle of 1800's where the mixture of oxygen and hydrogen were used in the making of jewelery. Today we use a different mixture of oxygen and acetylene which together can produce a flame temperature in excess of 6000 deg f. This type of equipment is not only used for welding, but also to heat materials for bending and straightening, brazing and cutting. An oxy-acetylene outfit is usually portable, versatile, and less expensive than a electric welding set up, and by using the correct tips, rods and fluxes, almost any metal can be welded, heated or cut. This equipment is ideally suited to the welding of thin sheets, tubes and pipes but not economical for thick section welds. Arc Welders Arc welding or stick Ppr pipe welding machine requires a higher skill level and mastery of certain techniques. Best for welding on thicker, rougher metals using a flux coated stick electrode fusing the work pieces together. To avoid porosity and attain the ideal weld travel speed, it is important to remove excessive scale, rust, moisture, paint, oil and grease from the surface of joints. A variety of electrodes are available for the different types of metal that is to be welded, cast iron, stainless steel etc. The electrodes need to be replaced as the heat builds up and the stick melts down causing a molten weld puddle on the work piece fusing the work pieces together. The weld must be cleaned when completed due to the flux electrode forming a slag blanket over the weld bead. Using an arc welder is a relatively slow process and is ideal for the more experienced user. MIG Welding MIG welding is generally a lot easier than gas or arc welding. A spool of weld wire is constantly driven by a feeding system through the MIG gun as the trigger is pulled, so unlike arc welding there is no need to constantly replace electrodes. , ...ادامه مطلب

Gas welding is a process in which a fuel gas such as acetylene, hydrogen, natural gas, etc. is mixed with oxygen in proper proportion to bu to get a flame which, if found adequate for melting a given metal, can be used for fusing and joining different parts of it. The process is very versatile because it can weld most of the commonly employed engineering metals and their alloys. Brief description of the well known variants in this class of welding processes follows. Oxy-Acetylene Welding This is the best known gas welding process and was successfully employed first time in 1903 when a welding torch for the purpose was developed. In this process acetylene (C2H2) is mixed with oxygen in the welding torch and is then but at the torch tip to give a flame with a temperature of about 3300oC which can melt most of the ferrous and non-ferrous metals in common use. Oxygen and acetylene are easily available in cylinders at temperature of about 1500 N/cm2 and 170 N/cm2 respectively. These are connected to the welding torch through hoses and are mixed and but to get different types of flames viz., neutral, oxidizing and carburising. The natural of the flame depends upon the ratio of the two gases. The neutral flame is most often used for the welding of most of the materials like low carbon steels, cast steel, cast iron, etc. The oxidising flame has higher proportion of oxygen than acetylene and is used for welding of manganese steel, brass and bronze whereas the carburising flame has higher proportion of acetylene in it and is used for welding aluminium, nickel, etc.plastic pipe cutter It is quite common to use filler material with gas welding through if need be, the process can be used without filler as well. Commercially, oxy-acetylene process is very widely used for welding of ferrous and non ferrous metals particularly for welding thin sections upto 6 mm. A large percent of the repair work is also done by oxy-acetylene welding. Typical applications of the pro, ...ادامه مطلب

According to a latest survey, most of the fabricators said that welding is one of the most sought after skills in metal fabrication. It is a great art or process that is commonly used for joining materials, usually thermoplastics or metals. Presently, there are so many metal fabricators that offer professional services to all the people. If you are planning to hire such services, then you should make sure whether they meet your specific requirements or not. It would be better to conduct a little research over the World Wide Web. Before hiring any company, an individual should speak with their representatives personally and clarify all the doubts. From them, you can ask a number of questions such as:- Price Estimate In all over the world, there are numerous experienced metal fabricators that provide a free estimate based upon labor and material that used by them for the project. Once you get a quote from different companies, you should compare them in order to hire the best service provider.pipe welding machine Projects Handled Before hiring any fabricator, you should check out their portfolio section to know what type of projects they have handled earlier. This way, you can get a great idea about their work quality. Also, make sure whether they deliver projects on time to the clients or not. Techniques and materials used Most of the fabricators specialize to work with all types of metals such as brass and copper, mild steel, aluminum etc. To offer excellent services, they always use the best tools, equipment and expertise. What's more, their expert team always use great techniques for creating the desired product as per the customers' expectation. Engineering services or custom solutions If you want to design a product according to your needs, then you should ask from the company whether they are offering such services to the people or not. Also, ensure their engineers have undergone with extensive training or not. ,pipe welding machine ...ادامه مطلب

　　You also need to have an excellent handle in the demands of factory or your business. Ask yourself what you plan to do with your welding device. You must get familiar with the caliber of any specified welder, what it's capable of, what you are able to get out of it, etc. 　　For instance, the electricity requirements of the machine for welding aluminum is not the same as the one you must weld sheet metal or cast iron (one of the most difficult substances to weld). You regularly see welder for sale online and on your surroundings.You'll get more use, enjoyment, and satisfaction from your welding machine that is the perfect fit for your needs if you take time to analyze and evaluate your welder choices.
