Question

Прочитайте 5 -й абзац текста и ответьте письменно на следующий вопрос: What are the conditions of welding in space? 5. And what about welding in outer space? The scientists understood that welding had to be done in conditions of weightlessness, in nearly complete vacuum and within a broad range of temperatures - from 150°C below to 130°C above zero. The equipment, of course, must be reliable and safe.

Answer 1

The results of studies have confirmed the possibility of welding under dynamic weightlessness

Answer 2

The conditions of welding in outer space are as follows:

1. Weightlessness: Welding in space must be carried out in conditions of weightlessness or microgravity. The absence of gravity affects the behavior of molten metal, making it difficult to control the welding process as it would be on Earth.

2. Nearly complete vacuum: Space is an environment with low pressure, so welding must be performed in a nearly complete vacuum. The absence of air or any other gas is essential to prevent oxidation and other undesirable reactions that can compromise the quality and integrity of the weld.

3. Broad temperature range: Welding in space requires dealing with a wide range of temperatures. The process must be adaptable to work at temperatures as low as 150°C below zero and as high as 130°C above zero. The extreme temperature variations in space demand welding techniques and equipment that can withstand and function effectively in such conditions.

4. Reliable and safe equipment: Due to the harsh and challenging conditions of outer space, the welding equipment must be highly reliable, durable, and specially designed for space applications. The safety of astronauts and the success of the mission depend on the proper functioning of the welding tools and machinery.

In summary, welding in space demands specialized equipment and techniques that can handle weightlessness, low pressure, extreme temperature fluctuations, and ensure the weld's quality and safety of the overall mission.
