Enter the weld length and welding speed into the calculator to determine the welding time. This calculator helps in planning and estimating the time required for welding projects.

Welding Time Formula

The following formula is used to calculate the welding time.

WT = L / S

Variables:

  • WT is the welding time (minutes)
  • L is the weld length (inches)
  • S is the welding speed (inches per minute)

To calculate the welding time, divide the weld length by the welding speed.

What is Welding Time?

Welding time is the duration it takes to complete a weld along a joint of a specified length at a given speed. It is a critical factor in project scheduling, cost estimation, and labor planning in the welding industry. Understanding the welding time is essential for efficient workflow and resource allocation in fabrication and construction projects.

How to Calculate Welding Time?

The following steps outline how to calculate the Welding Time.


  1. First, determine the weld length (L) in inches.
  2. Next, determine the welding speed (S) in inches per minute.
  3. Next, gather the formula from above = WT = L / S.
  4. Finally, calculate the Welding Time (WT) in minutes.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

weld length (L) = 30 inches

welding speed (S) = 5 inches per minute
