One type of welding is tube welding. Another type if mig welding.
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.

what is the difference between ultrasonic welding & radiographic welding
While welding as it is known today did not come about until the 19th century, primitive welding processes have been in existence for thousands of years. Metal tools and weapons have been discovered dating back to 1000 B.C.E. It was during the Bronze Age that humans first learned to fuse two metals together using heat. The Iron Age brought about increased use of fusing procedures. In the Middle Ages, blacksmithing was developed, which joined two metals through the use of fire and hammering.

it is imporatant mostly today,because it is used in arc welding light bulb flourescent tube so its hard for us if it is not discovered right?
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.
Digital Control of welding when welding
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.
