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.

∙ 11y agoseam welding is same as of spot welding.' Difference is that in case of seam welding the rotating wheel is used.....nd it is the fast process than spot welding.....

∙ 16y agoseam welding has to be performed from one end to the other. flash welding can do the entire seam at once.

Difference between ERW and SAW 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.
Why seam welding is better than that of spot welding?
The clue is in the question! If you weld a seam, or a spot which do you think is stronger? Take the example of the ordinary household radiator, it is seam welded, and they are usually watertight, it would be hard to make a waterproof seal with a spot welder and if you did try you would find it is very slow. A seam welder uses two rollers as the contacts instead of the copper rods, the rollers are inevitable faster as they can move along the piece easily and you get a perfect seal or seam when done, excellent.
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.
Why spot welding robot not used in arc welding?
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.
What is land in spot welding process?

Can a threaded joint be welded?
yes ,we can weld this. welding is the process of joining two materials .we can join this by spot welding or by arc welding.
Can you use Stick Welding machine for Spot Welding if yes how?
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.

What is the temperature of resistance spot welding?
