Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incompatible welding filler material for 6061 aluminum.Utilize ER4043 or ER5356 filler wire when TIG welding 6061 aluminum to ensure optimal joint strength and ductility.
Improperly supporting the pipe during welding, leading to distortion.Employ adequate bracing and fixturing to maintain pipe alignment and minimize thermal distortion during the welding process.

Common Applications

  • Structural framing and support systems
  • Marine and offshore components
  • Aerospace and automotive tubing
