Does anyone know when and who invented the electric welding machine?

In 1881, the Frenchman Demeritens invented the first carbon arc welding machine. In 1898, the German Klerbacterschmidt invented copper electrode arc welding. In 1919, Halslag invented AC welding.

In 1923, Stordy invented surfacing welding. In 1926, the United States Langmuir invented Qingyin atomic hydrogen to improve the difference in welding. In 1930, the former Soviet nuclear Union Robinov invented submerged arc welding.

In 1936, Wasserman of Switzerland invented low-temperature brazing. In 1943, BEHL invented ultrasonic welding in the United States. In 1944, the British Carl invented ** welding.

The purpose of the electric welding machine is to use the high-temperature arc generated by the positive and negative electrodes in an instantaneous short circuit to melt the solder and the welded material on the electrode, so that the contact object is combined. Its structure is a high-power transformer. Welding machines can generally be divided into two types according to the type of output power supply, one is AC power supply and the other is direct current.

Using the principle of inductance, the inductance will produce a huge voltage change when it is turned on and off, and the high-voltage arc generated by the positive and negative electrodes when they are short-circuited in an instantaneous short circuit is used to melt the solder on the electrode to make them atomically combined.

The so-called invention is not simple. Almost all of them have to go through: ideation, ideation, hands-on production, experimentation, failure, correction, remake, try, practice, and application! It takes a lot.

Electric welding machine is no exception, looking back on the history of welding, from the invention of forging welding technology in Egypt more than 3,000 years BC, and the Yin Dynasty in China more than 2,000 BC used casting welding to manufacture weapons; Before 200 B.C., China had mastered the brazing of bronze and the forging and welding of iron.

In 1881, the Frenchman Demeritens invented the first carbon arc welding machine. From the same year, the r. of the United States h.

It took Dr. Thurston six years to complete all the tests on the strength and elongation of a full range of copper-zinc alloy brazing metals. In 1885, the American Elihu Thompson obtained the patent for a resistance welding machine. In the same year, the Russian Benardos Olszewski developed the technique of carbon arc welding.

In 1888, the Russian Hг.c Invention of metal arc welding.

1889-1890, American C l.For the first time, Coffin used optical wire as an electrode for arc welding.

In 1890, the American C l.Coffin came up with the concept of welding in an oxidizing medium.

In 1890, the Briton Brown made his first attempt to rob a bank using oxygen, gas cutting. The above journey is not simple, but it has gone through such a long evolution, it is really hard-won!
