About the Arc Welding Process Simulator

Traverse a gas-shielded torch along a prepared butt joint. The luminous arc, pool, deposited bead and cooling heat trail respond to current, voltage, travel speed and shielding availability.

What the simulator shows

• A 3D process cutaway of a shielded arc torch, heat input per length and bead deposition, with labeled components you can select. • Controls: Welding current (60-200 A), Arc voltage (18-30 V), Torch travel speed (2-12 mm/s), Shielding gas available. • Live readouts: Electrical arc power; Effective heat per unit length; Bead length; Effective delivered heat; Missing shielding indicator; Joint traversed. • Three guided experiments (Slower travel, Higher power, Lose shielding), a built-in model verification check, a timestamped event log, a trial report and a short knowledge check.

Equations used

Electrical power = V I / 1000 kW Effective heat/length = η V I /(1000 v) kJ/mm; η=0.8 Effective energy = η V I × active time /1000 kJ Travel distance = min(80, v t) mm.

Model limits

Steady voltage/current heat accounting with an assumed 0.8 efficiency. Visual pool size and bead cooling are illustrative, not weld penetration, metallurgy, defect acceptance or a welding procedure qualification. Torch and spindle-like visuals are slowed for clarity. Dimensions, motion and process time are enlarged where stated for explanation. These are educational models, not machine programs or qualified production procedures.

Frequently asked questions

At fixed power, does slower travel increase heat per length?

Yes. The same energy rate is spread over fewer millimeters each second.

Does heat-input arithmetic certify weld quality?

No. Geometry, metallurgy, shielding and procedure qualification also matter.

What does the Arc Welding Process simulator not model?

Steady voltage/current heat accounting with an assumed 0.8 efficiency. Visual pool size and bead cooling are illustrative, not weld penetration, metallurgy, defect acceptance or a welding procedure qualification. Torch and spindle-like visuals are slowed for clarity. These are educational models, not machine programs or qualified production procedures.
