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.
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.
Explain seam welding and percussion welding?
Seam welding- resistance welding process involving the use of (normally) copper or copper alloy rollers to simultaneously pass high current (10^4 amps and usually in pulses) and apply pressure to bond a lap seam between two pieces of sheet metal. Percussion Welding- arc welding process involving the use of a capacitor bank to bond on the order of milliseconds. A high current electric arc is developed between the items to be joined, and the items are rapidly accelerated together.
What is a long seam weld on a vessel?
A long seam weld on a vessel is a continuous weld that runs along the length of the cylindrical structure, typically used to join two edges of metal plates together. This type of weld is crucial for maintaining the strength and integrity of the vessel, especially under pressure. It is commonly found in the construction of tanks, pipes, and boilers, where it ensures a secure and leak-proof connection. Long seam welding can be performed using various techniques, including electric arc welding and submerged arc 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 is seam pipe?
The pipe which is formed by seam welding.
What is difference between seam welding and spot welding?

Which welding is similar to projection welding?
Seam welding is similar to projection welding as both processes involve the use of electrodes to apply pressure and heat to weld metal parts together. In seam welding, a continuous seam is created by overlapping metal pieces, while projection welding focuses on specific raised areas or projections on the workpieces. Both methods utilize electric resistance and are effective for joining materials in various applications.

What welding process uses a resistive heating system to achieve metal deposition?
The welding process that uses a resistive heating system for metal deposition is known as Resistance Welding. In this process, electrical resistance is utilized to generate heat at the interface of the materials being joined, which causes them to melt and fuse together. This method is commonly used for spot welding and seam welding, particularly in the automotive industry for joining sheet metal components. The efficiency and speed of resistance welding make it suitable for high-volume production.
What seam is most often used in dressmaking?
open seam
What are the points which determine the choice of seam?
You need to explain what seam you mean? A seam of coal? A seam in a jacket?
What does ag an loin mean in English?
"Ag an loin" translates to "at the seam" in English. It is an Irish phrase that can refer to a literal seam, such as in fabric or stitching, or can be used metaphorically in various contexts.
