Key Guidelines for Using a Waterstop Welding Machine

Power Supply: Operates on standard 220 V AC.
Precision in Jointing: Ensure both ends of the waterstop are aligned accurately and evenly before welding, so the joint achieves proper waterproofing and tensile strength.

This method enables the creation of strong, reliable joints between waterstop ends, preventing water leakage at the connection point.

Waterstop Welding Machine – Technical Description

The waterstop welding machine is a specialized thermal‑joining tool designed for polymer waterstops, especially PVC types, used in waterproofing concrete structures.

Physical Specifications

Body: Durable metal housing with a heat‑insulated handle
Heating Element: Internal electric heater, distributing heat evenly to both sides of the hot plates
Hot Plates: Dual‑sided for simultaneous heating of both waterstop ends
Working Temperature: Adjustable, typically 150 – 300 °C
Weight: Approximately 3 to 7 kg
Dimensions: Optimized for easy on‑site use in workshops or construction sites

Chemical & Material Specifications

Hot Plate Material: Heat‑ and corrosion‑resistant metal alloys capable of withstanding prolonged high temperatures and contact with softened PVC
Surface Coating: Industrial Teflon or ceramic coating to prevent molten material adhesion and to enhance chemical resistance
Environmental Resistance: Stable against cement dust, concrete additives vapors, and industrial adhesives present in construction environments

Performance & Advantages

Produces uniform, strong, and watertight joints between waterstop ends
Prevents molecular damage to the waterstop polymer during welding
Ensures long‑term joint durability in water‑retaining structures such as pools, tanks, tunnels, and basements

Butt‑Joint Welding of Waterstops – Procedure

Preparation: Position the two waterstop ends on either side of the welding plate of the machine, aligning them precisely at the joint area.
Melting: Allow both waterstop ends to heat and soften on each side of the hot plate until a molten layer forms on the contact surfaces.
Final Jointing: Remove the hot plate, then immediately press the molten ends together in perfect alignment to form a uniform joint.

This process ensures that the joint remains fully watertight while also providing suitable tensile strength.
