Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incompatible welding consumables leading to reduced corrosion resistance.Utilize GTAW (TIG) or GMAW (MIG) with filler materials specifically designed for 316 stainless steel, such as ER316L.
Improper post-weld cleaning resulting in surface contamination.Thoroughly degrease and remove all welding slag and spatter, followed by pickling and passivation to restore the protective chromium oxide layer.

Common Applications

  • Chemical processing equipment
  • Offshore and marine fluid systems
  • High-pressure hydraulic lines

⚠️ Engineering Warnings

  • Ensure proper material handling to prevent galling or scratching of the stainless steel surface.
  • Always adhere to relevant ASME and ASTM standards for the specific application.
