Ca procédé utilise une électrode réfractaire en tungstène , placée dans l’atmosphère d’un gaz inerte , tels l’argon , l’hélium ou l’hydrogéne.ce gaz protége ainsi le métal de l’oxydation.la chaleur de l’arc formé entre l’électrode et le métal fait fondre les bords du métal.on peut ajouter un métal d’apport à la soudure, sous la forme d’une barre métallique nue au niveau de l’arc ou du point de soudure.ce procédé peut s’appliquer à quasiment tous les métaux et produit une soudure de haute qualité. Néanmoins, la vitesse de soudage est beaucoup plus lente que dans les autres procédés.

[edit] History
Tebessa was first a Numidian town, then, an outpost of Carthage in the 7th century BC. In 146 AC it became part of the Roman Empire and was known as Theveste (Hekatompyle in Greek).

During the 1st century CE, the Legio III Augusta resided there before being transferred to Lambaesis. It was made a colonia probably under Trajan.

There is mention of a council held there by the Donatists. Among its saints were St Lucius, its bishop, who in 256 assisted at the Council of Carthage and died as a martyr two years later; St Maximilianus, martyred 12 March 295; St Crispina, martyred 5 December 304. Some of its bishops are known: Romulus in 349; Urbicus in 411; Felix exiled by the Vandals in 484; Palladius mentioned in an inscription.

During the 4th and 5th century AD Theveste was a centre of Manichaeism as well. In June 1918 a codex of 26 leaves written in Latin by Manichaeans was discovered in a cave near the city. A month later Henri Omont found the missing initial 13 leaves. The whole book is now known as the Tebessa codex and it is kept in Cologne. It has been edited by Markus Stein (Bonn).

It was rebuilt by the patrician Solomon at the beginning of the reign of Justinian I, and he built a tomb there which still exists. Under the Ottoman Empire, Theveste had a garrison of Janizaries. Tebessa is very rich in ancient monuments, among them being a triumphal arch of Caracalla, a temple, a Christian basilica of the 4th century. At the time of Trajan, it was a flourishing city with c. 30,000 inhabitants.

In the 7th century AD, after the Arab invasion of the region, Theveste lost its importance. Later, during in 16th century, the Ottomans established a small military garrison there.

In 1851 it has been occupied by the French. Under the name of Tebessa it became the capital of a canton, then an arrondissement of the départment of Constantine in Algeria, later, it became capital of an arrondissement in the department of Bône, now (1974) it is capital of a province of its own, bearing the same name.
