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.
