Part 2

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

2. Прочитайте и письменно переведите текст “Arc Welding ”.

ARC WELDING

In arc welding the workpieces1 are not melted by a flame. They are melted by an electric arc. In order to create the arc, a powerful electric current must be provided.

The current must be at least 60 A, otherwise the arc will not create enough heat. For thicker workpieces, the current may be 250 A. In order to carry this current, the cables from the transformer should be quite thick or else they will overheat.

To supply the necessary current the transformer is used and to complete the electric circuit an earth clamp is used, which is attached to the workpiece. Then the current flows around the circuit and the arc appears. To strike the arc, the transformer should be switched on first.

The electrode holder contains an electrode rod which provides the filler metal2 to join the workpieces. As the current flows between the electrode and the workpiece, the tip3 of the electrode melts and falls onto the workpiece. While choosing an electrode type it is necessary to know:

a. Position to which the workpiece is to be welded.

b. Type and thickness of metal used.

c. Type of welding current.

d. Class of work: deep penetration4, surface quality, etc.
