WELDING SPECIALITIES
Ex. 1. Read and learn the words and word-combinations from the Active Vocabulary.
| welding – сварка joining – соединение application – применение heat – тепло pressure – давление widespread – широко распространенный to employ = to use = to apply – использовать, применять fabrication = manufacture – изготовление, производство erection – строительство, возведение to appear – появляться instead of – вместо bolting – скрепление болтами riveting– клепка, соединение заклепками to subdivide – подразделять arc welding – дуговая сварка | resistance welding – сварка сопротивлением electron-beam welding – электронно-лучевая сварка to depend – зависеть property – свойство, качество purpose – цель available – доступный, имеющийся в наличии, наличный to bring about – взрывать, совершать complex – сложный metal working = metal processing = metal treatment – обработка металла installation – установка, устройство demand– требование, потребность opportunity – возможность skill– искусство, умение, навык |
Ex. 2. Choose the right word from the ones given in brackets.
1. All gas (erection, welding, bolting) processes use oxygen.
2. There are several methods of (joining, building, erection) two like pieces of metal.
3. All welding processes are based on application of (bolting, riveting, heat) and (joining, erection, pressure).
4. Arc welding has a wide range of (pressure, heat, application).
5. The electron-beam welding method has become (widespread, resistance, complex) in our country.
6. Thermit welding can be (subdivided, employed, brought about) only on low carbon steels.
7. The plant deals with the (heat, resistance, manufacture) of heavy machinery.
8. Welding is widely used in the (pressure, riveting, fabrication) of machinery components.
9. Our nearest task is the (erection, bolting, riveting) of new buildings instead of the destroyed ones.
10. Welding replaced (erection, bolting, heat) and (riveting, pressure, resistance) which had been used in industry before.
11. All metal working processes can be (heated, brought about, subdivided) into several groups.
12. The welding processes include (erection, bolting, arc) welding as well as (widespread, resistance, complex) welding and (electron-beam, complex, available) welding.
13. The quality of welding (employs, depends, demands) on many factors.
14. What is the (purpose, joining, fabrication) of new experiments?
15. We can use only the (available, launching, outer) materials.
16. The Industrial Revolution was (employed, heated, brought about) by the application of new energy sources.
17. The curriculum is rather (complex, widespread, available) and includes many subjects.
18. Engineering (depends, brings about, demands) knowledge of foreign languages.
19. We have no other (application, opportunity, demand) to use the new welding (pressure, purpose, installation).
Ex. 3. Match the synonyms from the words in the left column to the words in the right one:
| 1) welding 2) application 3) joining 4) heat 5) pressure 6) widespread 7) to employ 8) fabrication 9) erection 10) to subdivide 11) to depend 12) purpose 13) available 14) to bring about 15) complex 16) metal working 17) installation 18) to demand 19) opportunity | a) use b) warmth c) fusion d) manufacture e) aim f) metal processing g) connecting h) chance i) force j) building k) equipment l) to use m) to be based n) to require o) to separate p) to cause q) broad r) obtainable s) complicated |
