Gas asylum welding, especially the asylum welding of carbon dioxide gas is gradually instead of manual Welding Electrode . Replace manual welding of carbon dioxide gas asylum welding greatly advances the welding obedience, has improved the quality of welding in the welding industry, it is a qualitative Pentium. However, the carbon dioxide gas the asylum welding in the welding large splash, constantly disturb the further growth of the welding industry. Argon / carbon dioxide mixed gas welding for asylum presented for this difficulty, at the same time greatly depressed the welding capital. Argon / carbon dioxide mixed gas than carbon dioxide gas asylum welding, the asylum gas welding mild steel a force aspiring

Argon / carbon dioxide mixed gas welding machine function and profile of asylum forming

Argon / carbon dioxide mixed gas than the oxidation of pure carbon dioxide is relatively much lower. Carbon dioxide in the arc is easy to differentiate into carbon monoxide and oxygen, differentiation of the gas in the reaction with the Mn, Si and other elements in the wire under low temperature conditions. Therefore, the adoption of a large number of Mn, Si and other elements in the gas welding of pure carbon dioxide asylum loss, the loss rate of about 40%. The adoption of argon / carbon dioxide mixed gas welding, because the carbon dioxide in the cut, the wire elements in the loss of a substantial reduction, the largest sector in the wire elements can be integrated into the weld pool to, as is bound to strengthen the weld machine function, anti- The tensile strength and toughness are enhanced response. The experiments confirmed that the adoption of 80% Ar +20% CO2 mixed gas welding, elements of the loss of about half of the gas of pure carbon dioxide asylum. Because oxygenated percentage reduction in the argon / carbon dioxide mixed gas, the weld profile oxides also greatly reduce the weld profiles are also more than an overview of the Gas Shielded Welding Wire of pure carbon dioxide asylum creamy. Therefore, the argon / carbon dioxide mixed with air in the shape of the welding machine functions and profiles much better than the performance of pure carbon dioxide gas.

Weld metal is a general impression, you only need to fire the torch, and welded together along the edge of the metal seams with carbon steel electrode. Or they may believe that you can run the same torch across any kind of metal, through security cracking movie. But the reality is, professional welding, in fact, related to a wide range of knowledge, is an art form and takes years of experience, to grasp a little bit. Even so, if you want to learn, you can use a few simple techniques to start. Once you've mastered the basics, and the idea of ??a beginner, then you can move to more complex skills, take longer to master.

Safety Precautions

Before you ever start any project, always think first about safety precautions. Replacement of equipment and supplies; you can not be replaced. You might think that the burn is the worst thing that can happen in a welding accident. However, the light hurt your eyes may occur from the process. Welding Material technology, the use of high-voltage electricity to create a weld, it always raises the possibility of electric shock or death, if you're not careful. When you start any welding project, be sure to wear a helmet to protect your eyes, head and hair. And do not forget the protective gloves and clothing. Finally, make sure to read and follow all safety precautions written especially metal welding equipment you are using the manufacturer.

Oxyacetylene welding (also known as oxygen-rich welding)

This is welded, the average person is most familiar with, which can often be easily "blowtorch". However, oxyacetylene welding is the most common type, it is actually the least used technology professionals. On the rise, it is less complex, more expensive than other types of welding. However, oxygen - acetylene is nowadays less common, because it is not very accurate, does not produce the weld clean, and may result in a slower cooling time, it relates to other welding techniques compared, due to weak welding connector. Even so, if you are interested in learning how to weld metal, you may want to practice in addition to other types of welding oxyacetylene welding. This will be a convenient skills, because this is the best type to use some common pipe or tube, you must use the welding equipment to repair, bending and cutting, welding and other projects.

Arc welding

These days the most common technology for arc welding. If you are learning how to weld metal, you will certainly need to practice arc welding. Instead of using the gas torch, arc welding involves the use of high-voltage power delivered to the sheet metal. Opposite a sheet metal arc welding, spark (or arc) jumps to enough heat to melt metal and a welding other reasons. In most cases, this process is better, because it is more accurate and produce a cleaner, stronger welds. "Arc" within the context of several different methods to choose, depending on the metal welding work, you need to do the type.

Shielded metal arc welding (SMAW) may be the best when you have a large welding or metal welding, in the unusual position, in which a rough weld is acceptable to the. Using this method, run electricity through the electrodes (or "stick") is actually melting, the welded joints. On the other hand, MIG welding, also known as metal inert gas shielded arc welding, gas metal arc welding (GMAW), if you are involved in metal welding works, the need for more speed might be better. With this welding technique, you do not use, you have to keep replacing them melt the rod. On the contrary, state-of-the-art electrical equipment you use by sending a molten metal, a continuous line of the Fed's sharp melting, the formation of the weld. MIG welding, TIG (tungsten inert gas) Welding Electrode is somewhat similar, but better thin material, you need a high-quality welding and speed is not important. When you learn, you will hear the other methods, such as flux cored arc welding (FCAW), submerged arc welding (SAW), plasma welding, but do not worry too much to remember all the various techniques. Time and just focus on one method you're comfortable with, you know how to use the point to learn something new in this method prior to welding.

Other welding methods

While you will be focused on arc welding and oxyacetylene welding you will learn how to weld, you may hear the other types, do not know what they are, such as resistance welding, energy beam welding and solid-state welding. Do not let that overwhelm you now. Many of these welding methods are useful in large, specialized industrial applications, do not really affect you understand how to weld.

Conclusion

I hope you now know a little about the basic concepts will be important to you, you learn how to welding. As you can see, although there are countless ways, each with its own unique set of equipment, procedures and purpose, in fact, only a few that you need to remember and practice the basic methods. To start learning and practicing a cheap arc settings. Their machines, just started to try some of the scrap metal pieces (read all the instructions and take all safety precautions, or course). What works and what does not. You will soon start to develop a style, is most suitable for your's. In addition, some of his oxyacetylene equipment, also tried this type. Rather rapidly, with a lot of practice, you will become a good novice will be able to master almost all of the project, you may experience
