Interactive Case Studies

Case Study 1: Aerospace Component Welding

You're tasked with welding a titanium alloy component for a spacecraft. Consider the following:

  • Material: Ti-6Al-4V
  • Thickness: 3mm
  • Joint Type: Butt joint

Case Study 2: Pressure Vessel Fabrication

You're welding a stainless steel pressure vessel for a chemical plant. Consider:

  • Material: 316L Stainless Steel
  • Thickness: 6mm
  • Joint Type: T-joint

GTAW Troubleshooting Guide

Common GTAW Issues and Solutions
IssuePossible CausesSolutions
PorosityContamination, inadequate shieldingClean materials, check gas flow, increase post-flow time
Tungsten InclusionExcessive current, touching electrode to poolReduce current, maintain proper arc length
Lack of FusionInsufficient heat, improper techniqueIncrease current, adjust travel angle and speed

GTAW Safety Reminders

  • Always wear proper Personal Protective Equipment (PPE), including a welding helmet, gloves, and flame-resistant clothing.
  • Ensure adequate ventilation to avoid inhaling harmful fumes.
  • Be aware of electric shock hazards – keep equipment properly maintained and workspace dry.
  • Protect against UV radiation – cover all exposed skin.
  • Handle and store shielding gas cylinders properly to prevent accidents.
