Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.
Spot welding is a form of resistance welding invented by Elihu Thompson in the late 1800s.
spot welding is one reason
A spot welding robot has generally 5 axis opposed to an arc welding robot that needs 6 axis. The controls and communication channels with the welding power supplies are configured differently as well.
land ?
yes ,we can weld this. welding is the process of joining two materials .we can join this by spot welding or by arc welding.
They sell a spot welding gun that plugs into a DC arc welder. If you have an AC225 or some other AC-only machine, this won't work. In general, tho, spot welders have their own power supplies so you don't need to reconfigure your stick welding machine for this.
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.

It is depend on machine
The only difference between the two is that projection welding requires preparation of the joint members in the way of adding a preformed dimple or projection. Spot welding is used without such preparation to the joint members. it's just heat and pressure.
Information is available on spot welding for one to read online at the Onspotwelding's official website. Other resources include the Slideshare's website and Millerwelds.
