Stainless Steel Sink Bowl Seam Welding Machine SS304 SS316 Food Grade Welder

Product Overview

The stainless steel sink bowl seam welding machine is engineered for SS304 and SS316 stainless steel, the two grades most commonly used in kitchen sink manufacturing. It produces food grade, airtight welds with a smooth surface finish, satisfying the hygiene and durability requirements of modern sink buyers.

Key Features

• SS304 and SS316 Compatibility: Welding parameters are optimized for both austenitic stainless steel grades used in kitchen sinks.
• Food Grade Weld Quality: Airtight, leakproof seams meet the hygiene expectations of food contact applications.
• Adaptive Parameter Control: Current is adjusted in real time to match material grade and seam length for consistent strength.
• Smooth Surface Finish: Surface roughness of Ra ≤ 0.8 μm reduces or eliminates post-weld polishing.
• Durable Seam Strength: Shear strength of 300 MPa or more ensures long service life of the finished sink.
