Welding Calculators & Configurators

Optimize your welding parameters and increase production efficiency with our suite of professional welding calculators. From heat input to gas consumption, get the technical data you need in seconds.

In modern fabrication, accuracy is the foundation of quality. Our online welding tools are designed to support engineers, project managers, and professional welders in calculating critical variables. Whether you are working on structural steel, stainless steel, or aluminum, using a verified welding parameter calculator ensures compliance with international standards and reduces material waste.

Our Technical Welding Resources Include:

  1. Heat Input Calculator,     Instantly calculate thermal energy input to ensure compliance with WPS and material limits.
  2. Weld analyse,    Analyze your heat input and instantly predict the mechanical properties of your weld.
  3. Dissimilar metal joiner,     Determine the correct filler metal and parameters for joining different alloy combinations.
  4. Shielding Gas Selector,     Find the optimal gas mixture based on your welding process and base material.

Preheat Calculator PRO

Prevent cold cracking and guarantee a safe weld joint with the Preheat Calculator PRO. This tool is specifically designed to quickly and accurately calculate the minimum required preheat temperature (Tp) for your project. Simply enter the chemical composition of your base material, the material thickness, joint type, and welding parameters, and the calculator will do the rest.

  • Three calculation methods: Supports calculations according to EN 1011-2 (Method A for standard structural steel / CEV and Method B for high-strength steel / CET) as well as the Ito-Bessyo / AWS method (Pcm).

  • Instant results: Alongside the required preheat temperature, you instantly see the equivalent value, the combined thickness, and the heat input (Q).

Weld Analyse Pro

Want to go a step further and fully optimize your welding parameters? The Weld Analyse Pro provides in-depth insight into the behavior of both the Heat-Affected Zone (HAZ) and the actual weld metal. This advanced tool helps you find the perfect balance in your heat input, preventing the formation of brittle structures (cracking) or excessively coarse grains.

  • Comprehensive predictions: Calculates the critical cooling time (t8/5) and predicts the expected hardness, yield strength, and tensile strength based on your settings and dilution percentage.

  • Visual insights: Instantly check if your heat input is optimal via the clear gauge and analyze the process using the interactive cooling chart.

  • Scientifically backed: Suitable for various steel types (from S235 to S1100) and based on the EN 1011-2 standard alongside proven Yurioka and JWES models.

Dissimilar Metal Joiner

Expert Material Matching

Select the optimal filler metal and welding parameters for joining mismatched alloys. Ensure structural integrity and prevent common issues like galvanic corrosion or cracking.

Welding dissimilar metals requires precise metallurgical knowledge to avoid brittle intermetallic phases. Our Dissimilar Metal Joiner simplifies this complex process by providing tailored recommendations based on your specific material combination.

Shielding Gas Selector for MIG/MAG & TIG Processes

Optimize arc stability and weld penetration with the correct gas mixture for every base material.

Selecting the right shielding gas is critical for arc stability, weld penetration, and reducing post-weld cleaning. Our Shielding Gas Selector helps you navigate through various mixtures—from pure Argon to complex CO2 and Helium blends. Simply input your base material and welding process (MIG/MAG or TIG) to receive a professional recommendation that ensures optimal bead appearance and mechanical properties.
