2 You will read the text “The past, present and future of aerospace join
processes”. Before you read suggest your answers to the following questions.
1. Why can welding be necessary on board of a spaceship?
2. What kinds of welding methods, in your opinion, are good for use in
space?
3. Why is welding in space such a difficult task?
3 Read the text again and say what events relate to:

Ø the future
Fill the table. Some examples are given.
The past The present The future
verifying the possibility
of thermal-cutting and
welding in space
testing in a flying
laboratory
completely new methods
of nondestructive testing
and diagnosing welded
structures
The future looks promising for
welding. It remains and will
continue to be a productive,
cost-effective manufacturing
method.
As far as design will be more and
more efficient there will be no
need in joining parts by means of
welding and it will see decline in
use.
