It is considered that the age of metal came with the advent of smelting it from ore. Archaeological data show that the earliest smelting and processing of copper ore was in Asia Minor about 700 years ago. Nevertheless, only the Iron Age technique for obtaining one-piece metal compounds reaches a significant development. Purer and denser iron grew by repeatedly recurring operations: heating, welding and forging. It was in those days originated the ability to weld some pieces of iron by heating and subsequent forging.

Using various techniques forge welding wizard, created a complex made of iron and steel. Welding is widely used for increasing the size of workpiece, the compounds of various metals and to give the desired shape of the product. In the VII-III centuries. bc frequently used welding on overhead parts in the manufacture of weapons and utensils (eg, swords, knives, axes and etc.) Most smiths limited welded steel platinum small part to the cutting blade, rarely used welding in which a solid steel plate was placed between two plates of the softer metal. Masters of Kievan Rus in the ninth and thirteenth centuries. in metallurgy and metalworking reached incredible heights. The technical level of craftsmanship is much faster than Western Europe.

Namely, in the Kievan Rus had mastered the production of high-carbon steel. Forge welding is a leading, well designed and disbursed to manufacturing products of iron or steel. Forge welding is used in the manufacture of about 70% of metal products. Mongol-Tatar invasion caused the decline of craft activities in Russia.
