& Welding Specifications

View certifications
TIG Welding (GTAW) Excellent

Preferred for precision work. Use ER308L/ER316L filler. Argon shielding essential.

MIG Welding (GMAW) Good

Faster than TIG. Use tri-mix gas (Ar/CO2/He). Watch for carbide precipitation.

Stick Welding (SMAW) Fair

Field repairs only. Use E308/E316 electrodes. Clean thoroughly after.

Laser Welding Excellent

Minimal heat-affected zone. Ideal for thin sections and precision parts.

Pro Tips

  • * Use low carbon grades (304L, 316L) to prevent sensitization
  • * Minimize heat input to reduce distortion
  • * Use back-purge with argon to prevent oxidation
  • * Post-weld passivation restores corrosion resistance
