1.Сопоставьте термины с их значениями и сделайте перевод. (Переведите и термин и определение)

2. Прочитайте и письменно переведите текст “Arc Welding with a.c. and d.c.”.

ARC WELDING WITH AC. AND DC.

Arc welding is possible with both d.c. and а.с.1

When welding with d.c, it is customary to connect the work2 to the positive side of the generator, and the electrode to the negative side. This is known as welding on straight polarity.3 When the electrode is connected positive and the work negative, the arrangement is termed reverse polarity.4

Low-carbon steels5 are almost always welded on straight polarity, since more heat is liberated6 at the positive connection which, in this case, is the work itself. This helps to heat the work.

Reverse polarity is used in welding with certain electrode types and in welding some special steels.

Both d.c. and a.c. can inherently7 produce equally good welds provided suitable electrode types and welding procedures are employed. From an economical point of view, a.c. welding is preferable12 because less electric power is consumed, a.c. equipment is less expensive and simpler to service, compared with d.c. equipment.
