Weld Heat Input

About

Weld Heat Input helps welders, inspectors, and fabrication teams calculate practical starting-reference heat input values without spreadsheets, paper notes, or a network connection. Use it to: - calculate heat input from voltage, current, travel speed, and process efficiency - view results in kJ/mm, kJ/cm, and kJ/in - switch between metric and imperial unit systems - apply built-in process efficiency presets or enter a custom factor - save local setups and recent calculations on your iPhone Why people buy Weld Heat Input: - faster than checking handbook notes or ad-hoc spreadsheets in the field - more focused than broad welding suite apps - paid once, with no ads, no account, and no tracking - built for offline shop-floor and job-site use Important: Results are starting references only. Always confirm procedure requirements, engineering review, applicable code, and inspection expectations before welding.
