About
The welding calculator that picks amperage on the first shot — TIG, MIG, stick, flux-core — heat input, travel speed, electrode sizing, all offline.
Tired of dialing in by feel? Tired of running test beads on scrap to find your settings? WelderCalc gives you amperage, heat input, travel speed, and electrode sizing for any process and any thickness, in seconds.
WHAT'S INSIDE
• Amperage — TIG, MIG, stick, flux-core; by thickness and process
• Heat Input — joules per inch, per process, per pass
• Travel Speed — IPM and meters/min, by deposition rate
• Electrode Sizing — TIG tungsten, stick rod, MIG wire by joint
• Gas Flow — CFH for argon, CO2, mixes
• Filler Calculation — rod count by joint, length, deposition rate
• Fillet Weld Strength — leg size, throat, allowable load
• Bead Reference — root, fill, cap by passes
• Code Reference — common WPS limits (informational)
WHO IT'S FOR
Pipefitters, structural welders, fab shop guys, mobile welders, welding students prepping for the AWS test. Anyone who'd rather lay good bead than burn rod figuring out settings.
