Only in the second half of the xiv century. its restoration has occurred on a fresh technical basis. Wide application Water engine has resulted in improved metallurgical plant – ore. To a new stage came out and forge welding business. Welding and cutting-edge technologies used to manufacture firearms: guns, mattresses and arquebuses. In the XV-XVI centuries.
blacksmith's work has risen to new heights. Martial hatchets with steel blades and a bronze ax, bracelets and rings with black decorations – great show artisan craftsmanship. Any technological tricks forge welding varies with time. They transform according to the level of craft and commodity production. As an expert went on to producing more and more mass production technology of its production all the more easier. Gradually, forge welding has reached such a development, which was used for the production of particularly critical parts (eg, railway rails).
The founder of this technology became British engineer Nixon. During this period, forge welding has reached its peak. Specialists craftsmen who owned a perfect technology, developed new techniques and methods compound complex parts, manufacturing tools, tools and weapons. Masters tried to upgrade the forge welding. Hammers manual labor was replaced by the work of mechanical hammers. But even the most advanced techniques blacksmith welding no longer meet the increasing needs of production. And since the xv century. along with a blacksmith welding began to develop welding processes. Since the beginning of the xviii century. Ural metallurgy and Ural blacksmith welding received worldwide recognition. Triumph has begun and the city of Yekaterinburg. Over the centuries the word welding Yekaterinburg are inseparable. At that time, forge, foundry, welding and soldering have been the main technological processes of metal compounds and produced by blacksmiths. Only in the late XIX-early xx centuries. welding has become an independent process. In the xix century. forge welding was mechanized industry. Forge welding was used for the manufacture of bimetal (steel + brass), tubes with a diameter of 600 mm, with straight and spiral seam. At the end of the xix century. based on advances in physics, chemistry, mechanics and electrical engineering in welding there was a kind of explosion. Were created by powerful electric heat sources and mastered oxy-fuel flames.
