Welding Calculator

Welding Calculator is the essential all-in-one tool for welding professionals, engineers, and trainees. Whether you are working on the shop floor or designing welded structures in the office, this app provides powerful calculation tools in two tailored modes.

WELDER MODE (Simple & Fast)
- Current Recommendation: Select electrode diameter and base material to instantly get the ideal amperage range.
- Unit Converter: Convert between metric and imperial units for thickness, length, and weight.
- Material Consumption: Estimate electrode or wire consumption based on weld length.
- Safety Reminders: Reference card covering protective gear, ventilation, and fire prevention.

ENGINEER MODE (Advanced & Analytical)
- Weld Strength Calculator: Calculate fillet weld load capacity. Input leg size, weld length, tensile strength, and safety factor to get throat thickness, effective area, allowable stress, and load capacity in kN.
- Heat Input Calculator: Calculate heat input using the standard formula with automatic category classification.
- Welding Process Database: Built-in reference of parameter sets for Carbon Steel, Stainless Steel, and Aluminum Alloy across SMAW, GMAW, and GTAW processes.
- Cost Estimator: Estimate total job cost including filler material and labor.
- Data Chart: Interactive chart showing the relationship between heat input, crack rate, and hardness.
