Nitrogen Cutting vs Air & Oxygen: Best Practice at Kakade Laser

Why Nitrogen Cutting Is the Best Practice

At Kakade Laser, we prefer nitrogen laser cutting over air or oxygen because it consistently delivers oxidation-free edges, cleaner finishes, and better weldability and coating adhesion. With our in-house nitrogen generator, we ensure reliable supply, lower cost of ownership, and reduced environmental impact.

Quick Facts:

Stainless Steel (SS): up to 25 mm

Mild Steel (MS): up to 4 mm

Supply: In-house nitrogen generation for consistency, quality, and sustainability.

Nitrogen vs Air & Oxygen: What Changes on the Edge

Air/Oxygen Cutting (Typical Outcomes):

Oxidized, darker edge

Increased heat-affected zone (HAZ)

Often needs post-processing (grinding/cleaning)

Lower coating/weld quality due to oxide layer

Nitrogen Cutting (Best Practice):

Bright, clean, oxidation-free edge

Minimal HAZ and burrs

Superior paint/powder coating adhesion

Weld-ready surfaces with fewer secondary operations.

Where Nitrogen Cutting Shines

Stainless steel enclosures and assemblies for industrial, pharmaceutical, and food applications

Precision sheet metal parts where surface finish matters

Components requiring powder coating or liquid painting

Welded sub-assemblies where clean edges reduce prep and rework

Quality & Cost Advantages You Can Measure

Better First-Pass Yield

Oxidation-free edges remove a common root cause of paint rejection and weld defects—leading to higher first-pass yield and lower rework.

Faster Downstream Operations

Clean edges reduce grinding and surface prep time, accelerating welding, masking, and coating workflows.

Total Cost of Ownership (TCO)

While cutting gas choices affect per-cut cost, nitrogen’s savings surface in reduced rework, fewer defects, and faster throughput—improving overall TCO for production programs.

Sustainability: Our In-House Nitrogen Generator

We operate an in-house nitrogen generator to eliminate frequent liquid gas deliveries and associated losses. The result is stable quality, lower logistics emissions, and improved energy efficiency across Unit-1 and Unit-2.

Technical Capability at a Glance

SS: up to 25 mm with nitrogen

MS: up to 4 mm with nitrogen

Tight tolerances and smooth edges optimized for coating & welding

Welded sub-assemblies where clean edges reduce prep and rework

Integrated downstream processes CNC bending, fabrication, welding, powder coating, liquid painting, anodising, zinc plating, UV printing, and more.

FAQs

Per-cut gas cost can be higher, but overall part cost often reduces thanks to less post-processing, improved coating/weld results, and fewer rejections.

For MS up to 4 mm, choose nitrogen when you need clean aesthetics, paint-ready edges, and weld-ready surfaces without oxide layers.

Yes. No oxide scale means better coating adhesion and more consistent film build, improving cosmetic quality and long-term performance.
