Soloha48 [4]3 years ago
4 0

Answer:

Listed Below

Explanation:

Weldability which is also known as joinability is defined as the ease with which  a material can be welded without producing any other effect .

Some factors which affect weldability are

1.Melting point of metal

  • Higher the melting point lower will be the weldability.

2.Thermal conductivity

  • Materials with higher thermal conductivity are difficult to join.

3.Reactivity

  • If the material reacts with surroundings like water or air, it is difficult to weld.

4.Coefficient of thermal expansion(α)

  • Higher the thermal expansion lower will be the weldability.

5.Surface condition

  • The material with dirty surface is difficult to weld for example if a surface has oxide layer on it it become difficult to weld it.

Explain why advances in technology can actually create more problems for engineers.
andrew11 [14]

Explanation:

Engineering is science in practical terms. It is the application of scientific findings in problem solving and creating a better world.

How does technological advancements create more problems for engineers?

  • Loss of job to automation: the world is driving at automating work processes through the use of  specially designed and crafted machinery. Work is now properly being done using machines with little to no human input in the whole process. This is a huge let off for engineers. Engineers have to compete with machines which are their own inventions for jobs now.
  • Fast paced work environment: machines can handle work more efficiently and faster than the people making them. There is an increasing race between engineers and their own inventions today for better product delivery. Unless a machine is faulty, they are more productive and efficient than man. This can cause engineers to want to catch up with their own inventions leading to a work life of stress.
  • Environmental problems they cannot solve: most inventions use components from the environment. They release effluents that are very difficult to be properly disposed or stored. This is a huge problem for engineers and can lead to ethical calls from the government and the populace. In short, they can create problems they are expected to solve but cannot solve.
  • Social problems: engineers can be portrayed as terrible beings for their own inventions. This leads to psychological problems on a good and creative invention. For example, rare earth metals in DR Congo are instrumental in making solar panels, but mining of these metals have forced several thousands of people into hard and intense labor on mines; there is a call on technological firms to stop exploiting people this way for their own gains.
  • Misuse of technology: any good technology can be put into the wrong use. A nuclear reaction can be packaged into a bomb and also, it can be the center of electricity generation on a commercial scale. How can engineers solve this kind of problem? Technological inventions are subjective in their usage.
