Spot welding vs seam welding ---> chassi

[cannabolic]

I thought I start a topic about welding.

I see there are different views about the matter.

Some say spot welding (me) while others do seam welding.

I'll put my pros and cons, but I am very interested to hear your opinion.

[u:c440e4a63d]Seam welding[/u:c440e4a63d]
Pros
* less time consuming

Cons
* more heat to the metal

[u:c440e4a63d]Spot[/u:c440e4a63d]
Pros
* easier
* less heat

Cons
* take more time

That's about my adds

I see a lot of seam welding, but I also see spot welding (Japan, even N2 TRD).

Please put your experience here.

I am not writing about stiffness cause I've heard/read that both are stiffer than the other.
