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 is difference between seam welding and spot welding?
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.
Is mig welding better than gas welding in terms of strength?
It depends on what metal you are welding and how thick it is, but in general, no. Any process that will raise enough heat for adequate weld penetration is for the most part equal.
What typy of welding machine do you need to weld steel?
Steel is such a commonly used metal that almost any welding machine can accommodate it. Some are better than others though. Steel is usually welded with either sick welding, or wire welding (gas shielded or flux core)
What are the 5 different types of welding?
There are far more than 5 types or processes of welding. Currently the American Welding Society (AWS) states that there are more than 80 different welding and joining processes. However, some of the common welding processes include shielded metal arc welding (SMAW), gas metal arc welding (GMAW), gas tungsten arc welding (GTAW), flux cored arc welding (FCAW), and oxyfuel gas welding (OFW).
What are facts about welding?
# If you look into the flame you'll go blind, # if you touch the flame it will burn you, # your face is always hotter than your buttocks, # a cigarette always tastes better when lit by a torch flame, # always weld with a full gas tank, # you can get a tan/sunburn from welding, and # welding is fun when you weld random items together.

Is mtech welding engineering from nit thiruchi is better than mtech welding engineering from iit roorkee?

Why copper electrode does not melt while steel melts in spot welding?
Coppers conductivity allows electrons to flow much more freely than does iron. Internal resistance converts some of the electrical energy to thermal energy and heating occurs. Since iron has a lower conductivity (the same as higher resistance) than copper more of that electrical energy is transferred to heat.
Why is brazing better than welding?
Welding would melt the base metal and filler metal while brazzing only melts the filler metal.
Is mig welding better than gas welding in terms of strength?

Why are robots better for welding car panel than humans?
because there are not enough manual labor welders

Is welding an exhaust better than bolt on?
bolt on is better but cause more... I personally weld mine in 2004 and it starting to get loose. So i suggest u go with bolt on.
What is the advantage of double seam?
normal pipe size(nps) greater than or equal to 36" double seam is used.

What is the difference between seam and seamless pipe?
seam less pipes are having with out weld but produced by extension process it is costly than seam
