High Frequency Resistance Sink Seam Welding Machine CE Certified Kitchen Sink Welder

Product Overview

This CE certified high frequency resistance sink seam welding machine uses roller electrodes instead of cylindrical spot welding electrodes. The welded workpiece moves between the rollers to produce a sealed weld with overlapping molten cores, effectively joining the stainless steel sheets into an airtight sink bowl.

Key Features

• High Frequency Resistance Welding: HFW technology concentrates heat exactly at the seam for fast, efficient and repeatable welds.
• Roller Electrode Seam Welding: Continuously rotating roller electrodes create an uninterrupted overlapping molten core along the seam.
• CE Certified Construction: Machine complies with CE and CCC standards and is built to ISO 9001 quality management requirements.
• Stainless Steel Compatible: Optimized for SS304 and SS316 with sheet thickness from 0.8 mm to 2.0 mm.
• Airtight and Leakproof: Produces a fully sealed joint that withstands standard water and air leak testing.
