Forging Equipment
Each year, steadily increasing demand for forged products. Elements of the art forging decorate offices and homes of people. Sometimes forged products are striking in their beauty, and it seems that human hands can not do this. We see a variety of lanterns, twisted pipes, intricate openwork scrolls. But we can not even imagine that using a special forging equipment, we forged to make at home - in the garage or workshop.
This site is dedicated to forging equipment, and all its diversity, which can offer both domestic and foreign companies. Here you will read about the machines that produce forged products on an industrial scale, and the equipment for manual cold and hot forging. Learn how to communicate with officials of the companies will be able to advertise for sale or purchase of forging or other metal working equipment. Gradually, we will post here an interesting article about blacksmithing: stamping, art forging, hot and cold forging, forging equipment shop.
If you are interested in cooperation: Do you want to advertise on our site, if you have seen and read about their products, but want to leave here the contact information about themselves, more information about the company, forging equipment - write hlas [dog] mail [dot] ru We agree.
Metal welding
Welding is one of the leading process manufacturing and strengthening of parts, manufacture of building structures, pipelines and ships, repair parts and structures. Effective use of technological methods of welding and cutting metals.
Historically, the welding is known to mankind since the use of copper, silver, gold and, especially, iron, upon receipt of which was performed forging, ie, welding Critz (pieces of commercially pure iron). This is the first method of welding - welding of metal forgings.
Most prevalent in the production of electric arc welding, which is a purely Russian invention. For the first time an electrical arc discharge was identified Petersburg professor of physics at St. Petersburg Medical-Surgical Academy Vasil Petrov in 1802, but only 80 years later (1882) Russian engineer Nikolai Benardos, working with lead-acid batteries, opened a welding method is not consumable carbon electrodes . He has mastered the technology of welding lead plates. Next, he developed methods of welding metal inert gas and arc cutting of metal. Benardos NN called his invention "Elektrogefest. According to Greek mythology, Hephaestus - god, patron of blacksmiths, so in this title introduced a new electricity-and the old (Hephaestus), which represents the first known method of welding (forge welding). 6 years later in 1888, engineer Slavyanov Nicholas Gavrilovic developed a method of welding consumable electrode.
Further work Slavyanov NN and Benardos NG performed together. The introduction of welding in the production took place very rapidly, so in Russia from 1890 to 1892 were on their technology renovated with high quality product in 1631, totaling more than 17 thousand pounds, it is mostly iron and bronze details. They have even developed a repair project of the Russian Monument foundry "Tsar Bell", but the work has not been resolved, and we can now admire the Russian imperishable symbols: a bell, which is not called, and the cannon, which is not fired.
A well-known bridge builder Academician Paton Comrade Paton, anticipating the great future of electric welding in bridge construction and other sectors of the economy, dramatically changed the field of his scientific career and in 1929 organized the first laboratory and later the world's first Institute of Electric Welding (Kiev). They were developed and offered a lot of new and efficient manufacturing processes of electric welding. During the war in a short time under his leadership were developed technology and auto stands for submerged arc welding of towers and buildings tanks. self-propelled guns, aviobomb.
Currently, widely developed such new methods of welding such as: powder material, plasma, the contact and electroslag, welding underwater and in outer space and others, many of which were developed at the Institute of Electric behalf of EO Paton, who recently headed the son of the founder of the Institute - Academician Boris E. Paton. In addition to the brain, in this industry, welding institute named EO Paton Welding issues successfully engaged many educational institutions (UPI CHIMESH, LGAU, etc.), institutions of the union "Remdetal.
Advantages of using welding to riveting and screw connections detail in the manufacture of building structures as follows:
-Rational design;
Metal-savings (up to 15 ... 20%);
-Higher productivity (15 ... 20%).;
-Lower costs (a decline of 20 ... 45%);
High-reliability connections.
