What type of welding machine use in spot welding or resistance welding?
Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.
Riveting and welding?
Riveting - when a solid fastener is placed in a drilled hole and expanded to hold an object in place. Welding - when a thin wire ('filler') is melted along with the area of bonding on the workpieces, which form a joint when cooled.
What are the sciences involved with welding?
Material science is very important to welding.The way a metal is heated and cooled determines its properties. When welding is done incorrectly it can result is very weak material around the weld. A very common place to see the effects of welding is around the weld of two pipes. After a period of time, a rust ring can form on either side of the weld (not right next to it, but a small distance away). Although the weld is strong, the surrounding material is weaker.
What are Types of cooling in transformer?
Air cooled water cooled oil cooled Totally enclosed fan cooled Refrigerant cooled
What is distortion in welding?
it moves Because almost all Elements expand when heated and contract when cooled. As you are welding the metal at that location is trying to expand because of the heat. Ahead of the weld area the metal isn't moving. Behind the weld area the metal is trying to contract as it cools. If the whole weld could be heated at once it would expand then contract at the same rate without distortion.

Do I need regular oil changes on an oil cooled welding machine?
no
What are the advantages and disadvantages of an air cooled condensers over that of a fan cooled in refrigeration?
The air cooled can be more efficient because they will use less energy. They are difficult to maintain if it stays too hot.

What were the disadvantages in the machine guns in world war 1?
Ive recently learnt about the machine gun in my history class and here is the main disadvantage but there were also a lot of advantages too. for instance the machine gun often over heated which caused a big problem because they weren't able to use them until they cooled back down. to cool them back down they usually put them in water but this could be a big problem if there weren't any water around.

How were machine guns cooled?
Early machine guns such as Maxim and Vickers were water cooled and had distinctive jackets around their barrels, except models intended for installation on airplanes. Most later machine guns are air cooled to make them lighter and more portable.

What are the advantages and disadvantages when using rubber?
Rubber has several advantages, including its elasticity, durability, and water resistance. It is also a good insulator and has excellent grip properties. However, rubber can degrade over time due to exposure to UV light and ozone, and it can be susceptible to high temperatures, which can cause it to melt or deform. Additionally, some individuals may have allergies to rubber compounds.
