Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect welding consumables leading to galvanic corrosion.Utilize 308L stainless steel filler metals for TIG or MIG welding to maintain corrosion resistance.
Inadequate edge preparation before welding, resulting in weld porosity.Ensure all edges are clean, free from grease, oil, and mill scale, and bevel appropriately if required by the joint design.

Common Applications

  • Industrial Ductwork Fabrication
  • Heat Exchanger Components
  • Flue and Chimney Liners
  • HVAC System Structural Supports
  • Corrosion-Resistant Enclosures

⚠️ Engineering Warnings

  • Handle with care to avoid sharp edges.
  • Always wear appropriate personal protective equipment (PPE) during fabrication and installation.
