Simply Solve Complex Weld Repair Issues

Before performing a hot tap weld or any weld repairs, know the potential risks. Hot tapping can cause two critical failures – burn-through and cold cracking.

eecHotTap is a cloud-based tool that will assess the risk of burn-through or cold cracking during a hot tap welding procedure. Use eecHotTap to predict peak wall temperature, maximum cooling rate, and the shortest cooling rate around the weld region. Solve a complex set of welding challenges with this simple tool.

Experience HotTap for yourself.


eecHotTap uses a transient thermal finite element analysis (FEA) solver to evaluate a wide variety of typical hot tap geometries, materials, and thermal boundary conditions.

Use the calculator to:

  • Predict peak wall temperature, maximum cooling rate, and shortest cooling time
  • Estimate cooling effect of the fluid for liquid and vapor fluid phases
  • Account for nucleate boiling, if wall temperature exceeds saturation temperature
  • Estimate material hardness after a microstructural change
