About This Project

Free, open educational tools for laser welding optimization

Project Overview

WeldingCalc is an individual open educational project developed by an independent developer. It provides free, professional-grade tools and resources to help welding engineers, technicians, and students optimize processes, ensure safety, and achieve consistent quality.

Why This Project Exists

Laser welding parameter optimization often requires complex calculations involving heat transfer, material properties, and safety considerations. Many engineers rely on trial-and-error or expensive commercial software. This project aims to democratize access to these tools while maintaining professional standards.

What Makes This Different

  • Completely Free: No subscriptions, no hidden costs, no registration required
  • Standards-Based: Calculations reference ISO, GB, and AWS standards
  • Educational Focus: Detailed explanations help users understand principles
  • Open Development: Continuously improved based on user feedback

Available Tools

The project provides 12 specialized calculators covering the full spectrum of laser welding optimization:

  • Core Calculators: Energy & Heat, Safety & Emissions, Multi-Variable Analysis, Surface Quality
  • Quick Calculators: Penetration Depth, Protection Distance (NOHD), Emission Threshold, Heat Gradient, Cooling Time, Cost Estimation, Crack Risk, Weld Width

Each calculator includes detailed explanations, practical recommendations, and references to relevant industry standards.

Knowledge Base

Beyond calculators, the project maintains a comprehensive knowledge base with:

  • Quick reference tables for materials and parameters
  • Technical glossary of welding terminology (A-Z)
  • FAQ answering common welding questions

Project Values

Disclaimer

While every effort is made to ensure accuracy, these calculators provide estimatesfor educational and planning purposes. Actual welding results depend on many factors including equipment condition, material quality, environmental conditions, and operator skill.

Always:

  • Verify results through test welds and process validation
  • Consult qualified welding engineers for critical applications
  • Follow all relevant safety standards and regulations
  • Use appropriate personal protective equipment (PPE)
