There are many different types, each has it's pros & cons.
Yes, pneumatic welding machines are possible and are used in specific applications where traditional welding methods may not be suitable. These machines utilize compressed air to drive welding processes, typically in industries that require lightweight and portable equipment. Pneumatic welding is often employed for tasks like spot welding or in environments where electrical hazards are a concern. However, the technology may have limitations compared to conventional welding methods in terms of depth and material thickness.
Welding is a versatile fabrication process used to join materials, primarily metals, through the application of heat and pressure. Its scope includes various techniques such as arc, MIG, TIG, and resistance welding, applicable in industries like construction, automotive, and aerospace. However, limitations include the requirement for skilled labor, potential for defects like cracks or porosity, and restrictions on the types of materials that can be effectively welded together. Additionally, welding may produce residual stresses and can be unsuitable for certain applications where the integrity of the base material must remain intact.
No, the main limitation of flux-cored arc welding is not restricted to ferrous metals. While it is commonly used for welding ferrous metals, it can also be used for welding some non-ferrous metals with the correct types of flux-cored wire. The main limitations typically involve issues like weld quality, porosity, and slag removal.

SAW welding is a type of arc welding while ERW welding is spot or seam welding. SAW stand for submerged arc welding while ERW stands for electric resistance welding.

The welding operation is stopped by moving the welding torch away from the workpiece to break the electrical circuit and extinguish the welding arc. Additionally, turning off the welding power source or releasing the welding trigger can also stop the welding operation.
Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.
CS Welding is known as Carbon Steel welding that is more beneficial and easy to use for welding purpose.
