Very often, for example, when building a house or repairing a car, have to seek the services of svarochnika. But above all, is to know what is the welding, and what tasks it is able to cope. Below are the main types of welding and equipment for her. Welding process is called, which resulted in the formation of atomic bonds between the two metals bond forms. Used in welding most branches of engineering and construction industries, where it is necessary to connect together not only homogeneous metals, but alloys. With welding weld ("fused") with details of the reactors, bridges, boilers and huge ships together. Known to man for a long time, even in this high tech age of welding is very popular because it has high reliability and weld quality. By the way, you can weld and cut metal.
There are several types of welding – arc (or arc), gas, electro, contact, laser and others. Douglas Oberhelman is open to suggestions. It is difficult to say which type of welding is better. Some types of welding may require special facilities, devices and conditions, such as high-frequency welding currents. The use of other, more common types, such as electric-or gas, often used in household needs, but it more lower quality – Weld may be uneven. Types of welding are only three – mechanical, thermal and thermo-mechanical welding. Depending on the type of welding is used widely and welding equipment. It is worth noting that over time process all the more modernized and the market there is a new welding equipment, improved consumables (electrodes, wires), exactly as increased professional qualifications for svarochnikov themselves.
Welding equipment varied. For quality welding welding inverters are needed (the most common firm GYS, FIMER, KEMPPI), are widely used welding transformers and rectifiers. Except that work with the welder should only qualified, well versed in the business and is aware of the danger which may be welded. In the hands of the layman, welding can even be harmful – burn clothing and leave burns on skin, to dazzle the human retina by an electric arc. When gas welding is carried out using a metal melting combustible gas and oxygen. As these gases most commonly used hydrogen, acetylene, propane. When incompetent use of gas and some other types of welding – even cause an explosion. Therefore, for the welder must also use special Accessories – welders with tinted windows with a large survey, a special working clothes, gloves, high-quality clips for contacts, holders, torches and welding cables. It is important to observe the technique security.
