How to Use

  1. Select welding process (GMAW, FCAW, SMAW) and base material (mild steel, stainless, aluminum) from the cat-filter dropdown
  2. Input travel speed (mm/min), wire feed rate (m/min), voltage (V), and current (A) parameters
  3. Simulator calculates heat input (kJ/mm), cooling rate, and predicts HAZ width and hardness profile; review tensile strength and impact toughness predictions against AWS D1.1 acceptance criteria

Worked Example

GMAW on ASTM A36 steel: voltage 28V, current 180A, travel speed 250 mm/min, wire feed 6.5 m/min. Heat input = (28 × 180 × 60) / (250 × 1000) = 12.1 kJ/mm. Simulator predicts HAZ width of 8.2 mm, peak hardness 310 HV in coarse-grained zone. Cooling time t8/5 from 800°C to 500°C: 4.8 seconds (ambient, no preheat). Resulting tensile strength 425 MPa exceeds minimum 345 MPa; impact energy 48 J at −20°C meets structural code requirements.

Practical Notes

  1. Higher heat input (>15 kJ/mm) on thick sections reduces cooling rate, lowering hardness but increasing softening risk in HAZ; preheat to 150°C for t8/5 > 10 sec to maintain toughness
  2. Aluminum (cat-filter selection) requires AC or pulsed DC to break oxide layer; simulator adjusts thermal conductivity (167 W/mK vs. 50 for steel) and predicts liquation cracking in 6xxx series if cooling exceeds 100°C/sec
  3. Stainless steel welds need travel speed <200 mm/min to avoid carbide precipitation; simulator flags corrosion risk if ferrite number drops below 3 FN in austenitic grades
