This is used differently in different countries. But generally, if a welder is contracted to do say 100 weld joints, of a 1" pipe, then the total work involved is 100" dia welding work. If 100 weld joints of a 2" pipe is 200 weld work and so on.
You multiply the number of welds by the diameter of the pipe that those welds are applicable to.
The inch diameter covered by a welder varies based on their expertise and the type of welding process used, but typically, a skilled welder can handle 2 to 6 inches for pipe welding. To calculate the number of welders required for welding a structure, first determine the total length of welds needed, then estimate the welding speed (in inches per hour) for the specific welder and process. Divide the total weld length by the welding speed to find the total man-hours required, and then divide by the available work hours to get the number of welders needed. Always consider factors such as work shifts, breaks, and the complexity of the welds when making your calculation.
depending on Head dia of the valve we have to set the Rotation of the valve, Stellite flow and Current
The thickness of the laser welding machine depends on the power of the laser generator inside the Laser Welding Machine, the thickness of the object to be welded. These two points are the most important.
You need more information than that ! You need the density of the material it's made from, and the thickness of the pipe !
You multiply the number of welds by the diameter of the pipe that those welds are applicable to.
The cost of welding pipe per diameter inch can vary depending on several factors, including the type of metal being welded, the welding process used, and the complexity of the project. Generally, welding prices are calculated based on the length of welds required, material costs, labor costs, and overhead expenses. It is recommended to obtain quotes from multiple welding professionals or companies to compare prices and ensure you are getting a fair estimate for your specific project.

Depends on the thickness of the pipe wall- there will normally be several layers of weld. A 36 inch pipe may require between 4.8 and 6.6 POUNDS of rod, allowing for a stub of rod that cannot be used. Lincoln Welding has a handy guide to pipeline welding you can read on line.
one inch is one inch; one inch dia refers to one inch diameter of a circle; it is still one inch
Inch dia = Number of weld joints X Size of the pipe
The meaning of dia inch is the number of weld joints multiplied by the dia of a given pipe size, since the weld joints is on the 6" pipe, the calculations should be 1 weld x 6" = 6 dia inch.
