Coupling, Covered Electrode, Crack, Creep or Plastic Flow of Metals, Cutting Torch

Finally we comes to last general definitions from letter "C" and today we will write about  Coupling, Covered Electrode, Crack, Creep or Plastic Flow of Metals, Cutting Torch. And with this post from Piping & Fabrication, I believe we will continue this article in the next post still with General Definitions but we start from Letter "D". and here it is the "C" thing we will read!

Coupling. 

Coupling

A threaded sleeve used to connect two pipes. Commercial couplings have internal threads to fit external threads on pipe.

Covered Electrode.

Covered Electrode

A filler metal electrode, used in arc welding, consisting of a metal core wire with a relatively thick covering which provides protection for the molten metal
from the atmosphere, improves the properties of the weld metal, and stabilizes the arc. Covered electrodes are extensively used in shop fabrication and field erection of piping of carbon, alloy, and stainless steels.

Crack

Crack

A fracture-type imperfection characterized by a sharp tip and high ratio of length and depth to opening displacement.

Creep or Plastic Flow of Metals.
At sufficiently high temperatures, all metals flow under stress. The higher the temperature and stress, the greater the tendency to plastic flow for any given metal.

Cutting Torch. 

Cutting Torch

A device used in oxygen, air, or powder cutting for controlling and directing the gases used for preheating and the oxygen or powder used for cutting the metal.

That's it for this post, and I hope this article will be useful to all of us and please visit this blog to see the new thing here.
