Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect cutting tools leading to edge deformation or heat damage.Utilize cutting tools specifically designed for stainless steel, such as abrasive cut-off wheels or laser cutters, and maintain appropriate speeds and feed rates to minimize heat input.
Inadequate preparation of weld joints, resulting in porosity or weak welds.Thoroughly clean and bevel weld joints to specifications, ensuring proper fit-up and utilizing appropriate filler materials and shielding gas for 304 stainless steel.

Common Applications

  • Custom fabrication of industrial components
