This welding calculator takes the figures you already have and applies the relationship behind welding calculations for you, giving length of weld (l), total weld length (l) and weld strength (p) from length of parallel weld (l2), length of transverse weld (l1), tensile strength (σt), size of weld (s), weld strength (p), weld strength (p), weld strength (p), weld strength (p), weld strength (p), shear strength (τ), throat thickness (t), throat thickness (t1) and throat thickness (t2).
What Is the Welding Calculator?
The welding calculator turns length of parallel weld (l2), length of transverse weld (l1), tensile strength (σt), size of weld (s), weld strength (p), weld strength (p), weld strength (p), weld strength (p), weld strength (p), shear strength (τ), throat thickness (t), throat thickness (t1) and throat thickness (t2) into length of weld (l), total weld length (l) and weld strength (p), so you can order the right amount of material the first time.
Material estimates are where projects go over budget. Getting the quantities right before the delivery arrives is worth more than any discount on the order.
How to Measure for the Welding
Measure everything in the same unit and take the largest dimension you can reasonably use rather than the average. Formwork, ground conditions and cutting waste all push the real figure above the theoretical one.
Where a plan calls for a specific thickness, check it against local building regulations before you order. The calculator reflects the relationship, not the code.
Allowing for Waste and Errors
Order a little more than the calculation suggests. The gap between the theoretical quantity and what actually arrives on site is normally waste, spillage, over-excavation and uneven grading, and all of it comes out of the same budget.
Write the figures down and compare them with what you actually used on site. That is how you build an estimate you can trust for the next job.
A Worked Example
Working through an example, with length of parallel weld (l2) set to 10, length of transverse weld (l1) set to 5, tensile strength (σt) set to 2, the calculator returns length of weld (l) of 0.07, and length of weld (l) (length1) of 12.5, and weld strength (p) of 7,777. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out length of weld (l)?
Enter length of parallel weld (l2), length of transverse weld (l1), tensile strength (σt), size of weld (s), weld strength (p), weld strength (p), weld strength (p), weld strength (p), weld strength (p), shear strength (τ), throat thickness (t), throat thickness (t1) and throat thickness (t2). The calculator then works through the relationship and reports length of weld (l), total weld length (l) and weld strength (p).
What does the welding actually calculate?
It takes length of parallel weld (l2), length of transverse weld (l1), tensile strength (σt), size of weld (s), weld strength (p), weld strength (p), weld strength (p), weld strength (p), weld strength (p), shear strength (τ), throat thickness (t), throat thickness (t1) and throat thickness (t2) and converts them into length of weld (l), total weld length (l) and weld strength (p) using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter length of parallel weld (l2)?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Do I have to fill in every field?
Only the fields a particular result depends on. If you leave one blank, the results that need it simply show a note instead of a number, and everything else still works.
Does anything you type get stored?
No. The whole calculation runs inside your browser, and nothing you enter is uploaded, logged or sent anywhere.
