## What is Weld Heat Input?

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.
