Before the development of current welding technology, sculptures made from metal were either cast or forged, and welding was primarily used in the construction industry. The first welded sculptures were credited to the Russian artist Vladimir Tatlin, [1] who created his first piece of art in 1913. Tatlin was an important figure in the Russian ...
Hardfacing may be applied to a new part during production to increase its wear resistance, or it may be used to restore a worn-down surface. Hardfacing by arc welding is a surfacing operation to extend the service life of industrial components, preemptively on new components, or as part of a maintenance program.
Any foreign material in the weld, such as the oxides or "scale" that typically form in the fire, can weaken it and cause it to fail. Thus the mating surfaces to be joined must be kept clean. To this end a smith makes sure the fire is a reducing fire: a fire where, at the heart, there is a great deal of heat and very little oxygen.
There are many different forms of welding, such as Oxy-fuel welding, Stick welding, MIG welding, and TIG welding. Oxy-fuel is probably the most common method of welding when it comes to creating steel sculptures because it is the easiest to use for shaping the steel as well as making clean and less noticeable joins of the steel.
Julio González Pellicer was born in Barcelona, on September 21, 1876.He came from a line of metalsmith workers; his grandfather was a goldsmith in Galicia. [1] González's father, Concordio González, owned a workshop and as a young boy, González learned from him the techniques of gold, silver, and iron metalwork.

In friction stir processing (FSP), a rotating tool is used with a pin and a shoulder to a single piece of material to make specific property enhancement, such as improving the material's toughness or flexibility, in a specific area in the micro-structure of the material via fine grain of a second material with properties that improve the first.(Ma) [6] Friction between the tool and workpieces ...
Vacuum cementing or vacuum welding is the natural process of solidifying small objects in a hard vacuum. [clarification needed] The most notable example is dust on the surface of the Moon. This effect was reported to be a problem with the first American and Soviet satellites, as small moving parts would seize together. [citation needed]
