Heat Input Safety Guidelines

Optimal Range: 0.8 - 2.5 kJ/in for most steels
High Heat Input: Can cause distortion, excessive penetration, and reduced toughness
Low Heat Input: May cause lack of fusion, incomplete penetration, or cold cracking

Filler Metal Calculator

Calculate the amount of filler metal required for a welding project.

Welding Recommendations

Preheat Temperature: Based on material thickness and carbon equivalent, preheat to 150-250°F
Interpass Temperature: Maintain between 300-600°F to prevent cracking
Electrode Selection: Use E7018 for structural steel, ER70S-6 for MIG welding
Gas Selection: Use 75% Argon / 25% CO₂ for steel MIG welding
