Calculators and worksheets for the subjects you study and the problems you meet in practice. Work through an example, try your own values, then test the same ideas in exam practice.
Welding arc energy calculator
Distinguish electrical arc energy from efficiency-adjusted heat input in a welding-inspection calculation. Check travel-speed units before comparing procedure values.
Open tool →FREE TOOLFillet weld quantity calculator
Estimate theoretical equal-leg weld metal before applying a supplied deposition efficiency. Separate geometric weld volume from actual consumable purchasing allowances.
Open tool →FREE TOOLThermal expansion calculator
Explain the direction of free thermal movement in a fabrication example. Do not infer weld shrinkage, residual stress or restraint force from a simple expansion result.
Open tool →FREE TOOLCorrosion rate calculator
Compare thickness readings taken at the same inspection location over documented dates. A thicker later reading needs measurement review rather than a negative-life extrapolation.
Open tool →FREE TOOLRemaining life worksheet
Use an independently established minimum thickness and a representative corrosion rate. Keep arithmetic remaining life separate from the inspection interval and fitness-for-service decision.
Open tool →Tools that connect the calculation to the concept
Each tool shows its method, units and assumptions, together with two worked examples. Example values are for learning; replace them with your own measurements or documented inputs. The related study links take you to the matching certification topic on Welding Exam.

Check the boundary of the answer
A useful result starts with the right inputs and an appropriate method. These tools explain what is calculated and what the method leaves out. User-supplied criteria remain identified as supplied criteria; a calculation does not automatically approve equipment, certify an inspection or establish regulatory compliance.
