Porosity is nothing more than bubbles in the weld. It does not reduce the strength by much when in small quantities. It does not look good and is an indicator of a problem that can usually be corrected with little difficulty.
The biggest application of explosion welding is the cladding of flat plate.
Look at a wall. Imagine welding on that wall from left to right or right to left. That is horizontal welding.
There are numerous commercially available welding and joining processes, with the most common ones including arc welding, MIG (metal inert gas) welding, TIG (tungsten inert gas) welding, resistance welding, and laser welding. Additionally, processes like spot welding, electron beam welding, and friction welding are also widely used in various industries. The choice of process often depends on factors such as the materials being joined, the desired strength of the joint, and production efficiency. Overall, the diversity of welding and joining methods enables tailored solutions for specific applications across different sectors.
Any standards that are welding related in the United States are designated by the American Welding Society (AWS).
The meaning of MPI in welding is Magnetic Particle Inspection.

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.

Welding Electrorodes or Welding Rods are used in arc welding. Arc welding is a special type of welding which uses a welding power supply to create an electric arc between the base material (e.g. steel) and the electrode. The Welding Ectrorodes can be used for all weldable aluminum and mild steel.
