Adams founded the American Welding Society (AWS). 1924 commemorative photo of activities of American Welding Association 19 19: C.J.Halslag invented AC welding. 1920: Gediehn discovers the thermal effect of plasma flow. 1920: The first steam ship "Fullagar" with fully welded hull was launched in Britain. About 1920: Start repairing some valuable equipment with arc welding. About 1920: Johnson process of resistance welding steel pipe was patented. About 1920: Poughkeepsie Socony, the first oil tanker made by welding, was launched in the United States. About 1920: Flux-cored wire is used for surface hardening. 1922: Prairie Pipeline Company successfully completed the laying of a crude oil pipeline from Mexico to Texas with a diameter of 8 inches and a length of 140 miles. 1923: Stodi invented the pavement. 1923: the world's first floating roof storage tank (used to store gasoline or other chemicals) was built; Its advantage is that the welded floating roof and tank wall form a tank that can be lifted like a telescope, so that the volume of the tank can be changed conveniently. 1924: magnolia gas company adopted oxyacetylene welding technology to build a 14 mile long all-welded natural gas pipeline. 1924: X-ray photography was first used by H.H.Lester of the United States to check the quality of castings to be installed for the power plant of Boston Edison Company with 8.3Mpa steam pressure. 1926: American Langmuir invented atomic hydrogen welding. 1926: Alexander invented the principle of CO2 gas shielded welding. 1926: A.O.Smith Company of the United States pioneered the manufacturing method of coating a protective solid coating on the metal electrode for arc welding (i.e. manual arc welding covered electrode). 1926: Cr-W-Co solder alloy obtained the first patent on flux-cored wire. 1926: Americans M.Hobart and P.K.Devers obtained a patent for using helium as arc protection gas. 1927: Lindbergh's solo Ryan monoplane successfully flew across the Atlantic Ocean, and the fuselage of the aircraft was made of all-welded alloy steel pipes. 1928: The American Welding Society published the first structural steel welding regulation, Rules for Fusion Welding and Gas Cutting in Building Structures, which is the predecessor of the current D 1. 1 structural steel welding rules. 1930: Georgia Railway Center adopts continuous welding method to lay railways in two tunnels. The welding track will be put into use when the line is connected in two years. 1930: submerged arc welding was invented by Robinov of the former Soviet Union. 193 1 year: The Empire State Building manufactured by all-steel structure welding process was completed. 1933: The first joint welded by arc welding laid a long-distance pipeline without lining structure. 1933: At that time, the Golden Gate Bridge in San Francisco, the highest suspension bridge in the world, was completed and opened to traffic. It is welded by 87750 tons of steel. 1934: Barton welding research institute was established. Evdin OsKalovics Barton, founder of Barton Institute, is the largest all-welded railway bridge on the Dnieper River in Europe-Barton Bridge 1934: The specification for unheated pressure vessels was jointly issued by API—ASME. 1935: Linde air products company of the United States perfected submerged arc welding technology. Wasserman invented low temperature brazing in Switzerland. 1939: Reineck invented the plasma spray gun. 1940: The first all-welded ship "Treasury" was built and launched at the dock in ingels, USA. 194 1 year: American meredith invented tungsten inert gas shielded welding (helium arc welding). 194 1 year: during the second world war, a large number of welding technologies were used in the manufacture of ships, planes, tanks and various heavy weapons. 1943: American Bell invents ultrasonic welding. 1943: for the first time, aircraft manufacturers used atomic hydrogen welding, submerged arc welding and MIG welding to weld hollow blades of aircraft steel propellers. 1944: Englishman Carl invents explosive welding. 1947: The former Soviet Union Bopoшeвич (Vorosevic) invented electroslag welding.
