Weld Heat Input

Run offline weld heat-input checks from volts, amps, travel speed, and efficiency presets.

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.
