Welding has been for many year from the middle ages. In the middle ages welding was known as blacksmithing. Blacksmithing is the technique of forging wrought iron and steel. Blacksmiths made horseshoes, weapons, and repair armor. Blacksmith get there name because they were smith and worked with black metals like tin, silver, and gold. With the work they do they need shatterproof hammers and handles because most of their work is forging metals with these hammers. In the middle ages blacksmiths made armor and weapons that were for the nights. They heated a steal till it melted and pour it into a rock with the design of the weapon or armor. Once it takes form the picket up with some players and start hammering it down to the shape they want. …show more content…
England has credit for the discovery of the acetylene. This was made arc between two carbon electrodes that use a battery. Voltaic cell was discovered by Allesandro Volta. This technique is were two different metals can connect and can become a conductor when wet. Sponge platinum is type when you cold press and then hammer when. This technique was used to build walls metal plates and more. There was a new welding discovery but was used in the 1900. This welding was called acetylene and was discovered by Edmund Davy in 1836. Later on in 1841 air hydrogen blowpipes were invented by a German named H. Rossier. In 1846 one man named James Nasmyth discovered that if you preparing weld surfaces with a slightly convex surface that it squeezes out the joints. This helps improve the strength in the joints. In the 19 century there was an improvement from …show more content…
The process he outlined is popular today.
1909:
The plasma arc system using gas vortex to stabilize the arc is invented by Schonner while working as BASF.
The Quasi-arc electrode is invented which is wrapped with an asbestos yarn by A.P. Strohmenger.
1910:
Patent issued to Charles Hyde for brazing steel tubes.
1911:
First pipeline created using oxyacetylene welding. Occurs outside of Philadelphia.
Matters develops the plasma arc torch for heating a metal fusing furnace.

1912:
Kjellberg received a second patent for an electrode with a heavier coating of asbestos and a binder made out of sodium silicate.
Lincoln Electric introduces first commercial welding machines
First auto body is welded by E.G. Budd using spot welding
Coated metal electrodes introduced by A.P. Strohmenger. Coatings were made from Clay or Lime. Also awarded a patent for an electrode coated with blue asbestos and a sodium silicate binder. First time an electrode produced a impurity free weld.
1919:
Alternating current welding was invented by C.J. Holslag, but did not become popular for another decade. Electric arc welding was the method used in the United States until 1920. The problem with the method was that the welding arc was unstable and the welds were not as strong as the metal being

    Later Thomas Browne wrote several books to investigate the Gilbert’s work and used the word “electricity” 1752: Benjamin Franklin conducted his experiment with a kite, a key, and a storm to prove lightning and tiny electric sparks were same. As I mentioned in previous, so many things were discovered around the electricity. In 1800 Alessandro Volta made the voltaic pile (similar to electric battery) to produce a steady flow of electric current by using the chemical reactions. His great invention is that “he transmitted the electricity by linking positive and negatively charged connectors and driving voltage or electrical charge through them. In 1831, Michael Faraday made a crude power generator (known as electric dynamo) to solve the problem of generating electric current in practical way.…

    reported that the growth of plate-like and branched Si3N4 whiskers, obtained from the catalyst-assisted pyrolysis of polymeric precursors followed a solid–liquid–sas–solid (SLGS) mechanism.12,15,17 Lin et al. reported that the Si3N4 nanotubes prepared from a thermal heating CVD method were formed via the VLS mechanism.33 Zhang et al. prepared Si3N4 nanowires by heating Si or Si/SiO2 powder in N2 or NH3 atmosphere with or without catalysts and suggested that the growth followed the VS process.22 It is obvious that SiO vapor as the Si source of nanowire plays an important role in the growth of Si3N4 nanowires no matter what the growth mechanism…

    They can grow upto several microns and have excellent electrical conductivity. Their growth can be re-tarded by adding 0.5% Zn, using reflowed tin or hot tin dip. Reflowed tin is a tech-nique that involves reheating a part above the melting temperature of tin after it has been electroplated with tin. Hot tin Dip is a process in which a part is dipped into a bath of molten tin above 450 F. This creates a thin layer at the interface of the base material & tin. 3.2 Voids The voids can be removed by adding sintered silver foil that is already coated with chromium and gold.…

    Like few tens to a few hundreds of briquettes – depending on the ingot size. The VAR process ingot production flow is shown in this flow chart. The primary electrode of titanium is connected to the cathode of the furnace. It is melted by the direct current arc produced between the water cooled copper crucible (which is connected to the anode of the furnace) and primary electrode (which is connected to the anode of the furnace). Molten titanium is solidified in layers in the water cooled copper crucible to form an ingot.…

    The pre-World War Two era began in 1789 when the German chemist Martin Klaproth discovered a new element “Uranium”, naming it after the planet Uranus. Then about a century later, in 1895, Wilhelm Rontgen performed experiments by running electric current through a glass tube acting like a vacuum and produced X-rays, thereby discovering the existence of ionizing radiation. The next year, in 1896, Henri Becquerel discovered that an ore “Pitchblende”, which contained Radium and Uranium, caused photographic plates to darken. Becquerel and his assistant, Villard, demonstrated that the photographic darkening on the plates was caused by beta radiation, alpha particles, and gamma rays. That same year, in 1896, Pierre and Marie Curie, the first woman to receive the Nobel Prize, coined the term “radioactivity” and were able to isolate the elements Polonium and Radium, later used for medical treatment, from pitchblende.…

    welding Welding the process to make, unite or fuse two or more pieces of metal as one. Welding uses electrons to heat metal to its boiling point in which it cools and bonds. Welding has been around since the egyptians they used it to make their tools to make the famous pyramids. In 1800 sir humphrey davy made a tool that was battery operated that was made just for welding. Today sir humphreys tool has been modified and made into as we know today as the arc welder.…

    Boisbaudran suggested the name gadolinium for the new element after the 18th century chemist and mineralogist Johan Gadolin. Pure metallic gadolinium was first prepared by French chemist and engineer Felix Trombe in 1935. A few months later Georges Urbain, Pierre Weiss, and Felix Trombe discovered that gadolinium becomes ferromagnetic at about room temperature, which was the first pure element to show this property other than the three ‘classical’ metals iron, nickel and cobalt. Along with this discovery they also found that gadolinium becomes more ferromagnetic than iron but only at very low…
