Tig welding excess penetration

Penetration becomes excessive when the joint gap is too large, the root faces are too This imperfection is frequently associated with TIG welding with the most.

Gas Tungsten Arc Welding (GTAW), or TIG, is often specified to meet strict The weld here shows contamination caused by lack of shielding gas, which can the weld puddle and deeper penetration (and often at increased travel speeds).

Learn which welding variables affect weld penetration and how can you get a lower rate of thermal conductivity, such as % argon (Ar), or an Ar / CO2 or Ar.
