TIG welding process

A structured methodology that ensures top-quality joints and hygienic finishes.

Preparation

Edge cleaning, oxide removal, fit-up check and selection of a compatible filler material.

  • Mechanical and chemical cleaning
  • Tolerance verification
  • Electrode selection
  • Shielding gas preparation

Tack welding

Strategically placed tack welds to maintain alignment and prevent distortion during the process.

  • Precise positioning
  • Fixing points
  • Distortion control
  • Alignment check

Weld bead

Weld bead execution with control of amperage, travel speed and filler deposition for optimal penetration.

  • Temperature control
  • Constant travel speed
  • Argon shielding
  • Uniform penetration

Cleaning

Removal of surface oxidation, weld bead cleaning and passivation to restore corrosion resistance.

  • Weld bead brushing
  • Chemical pickling
  • Surface passivation
  • Visual inspection
