Зварювання забезпечує з’єднання металів, їх сплавів, пластмас та інших речовин.
Одним з основних параметрів контактного зварювання є контактний опір в місці стикання поверхонь, які треба з’єднати.
Зазвичай, у кожному пасажирському транспортному засобі є від трьох до чотирьох тисяч точкових зварних швів.
Зварювання тертям підходить для виробництва таких виробів, у яких одну з деталей, що зварюються, можна обертати на високій швидкості перед тим, як встановити контакт з іншою.
Висока концентрація тепла у дузі дозволяє з’днувати метали дуже близько до зони термічного впливу.
З’єднання має бути доступним для сфокусованого лазерного променя.
11. Read the text. Retell it in the past/future tense.
Composite ceramic coating material combines the wear resistance of aluminium with the surface finish of titanium. The coating has high hardness and can be brush finished, ground and polished. Porosity is less than 1%, dielectric strength is also low. Furnished as powder, the coating applied by plasma flame gun produces coatings that are highly resistant to liquid wetting and to temperatures to 1000oF (538oC).
Discussion
1. Are the following statements about the text true or false? Why?
All types of welding may be divided into pressure welding and fusion welding processes.
In thermit welding two metal pieces are joined and forced together by force from hammer.
Electric welding utilizes the heat of electric current for heating metal parts.
One of the main parameters of RW is the contact resistance at the interface of the surfaces to be joined.
The most widely spread kind of RW is friction welding.
Tungsten inert gas welding process is a simple easy maintained process.
Laser beam welding provides structural strength.
Plasma arc welding utilizes a stable gas flame as the heat source.
