General Information
Overview
EN 13705:2004 - Welding of thermoplastics: machines and equipment for hot gas welding (including extrusion welding) is a CEN European Standard that specifies general performance requirements for machines and equipment used to weld semi‑finished thermoplastic products by hot gas, including hot gas extrusion welding. It covers design, marking, documentation, safety and functional requirements for manual hot‑gas guns, continuous liner welding machines and extrusion welding systems.
Key topics and technical requirements
- Scope and references
- Applies to hot gas welding and hot gas extrusion welding of thermoplastics.
- Normative references include EN 562 (pressure gauges) and EN ISO 2503 (pressure regulators).
- Marking and documentation
- Equipment must be permanently marked with manufacturer, type, serial number, characteristic data and mains supply.
- Supplied documentation must include technical description, nozzle specification, servicing schedule and fault diagnosis.
- Nozzles and accessories
- Nozzle materials must be corrosion‑resistant, non‑particulate and not copper or copper alloys.
- Nozzle surfaces should be smooth/polished; round nozzles require a straight length of at least 5×D before the mouth (D = outlet diameter).
- Manual hot gas welding equipment
- Gun design: balanced centre of gravity, ergonomic handle, infinitely variable power, prevented accidental actuation, heat‑insulating non‑conductive handle.
- Air supply: dry, oil‑free air; filters required if taken from compressed circuits; flow must be adjustable and stable.
- Temperature measurement: hot gas temperature measured inside nozzle outlet at 5 mm depth using a thermocouple (≤1.5 mm bead) after ≥10 min warm‑up.
- Controls: flowmeters, pressure regulators, temperature control and automatic over‑temperature shut‑offs.
- Continuous liner welding machines
- Electrically driven carriage, variable carriage speed, swivel welding unit and automatic shut‑off if an obstacle is encountered.
- Extrusion welding systems
- Core elements: plastification system (screw or heated chamber), preheating system, welding head and welding shoe.
- Plastification requirements: homogeneous extrudate, temperature display, extrusion control (continuous adjustment above 1.5 kg/h), extrudate temperature fluctuation ≤ ±3 °C, prevention of cold feed before operating temperature.
- Preheating system: heated gas (usually air), temperature continuously adjustable, fluctuation ≤ ±10 °C, minimum flow 200 l/min (cold air at ambient pressure).
Applications and users
- Practical applications: welding of plastic floor coverings, liners, geomembranes, roofing membranes, tanks and other semi‑finished thermoplastic assemblies where hot gas or extrusion welding is used.
- Primary users: equipment manufacturers, product designers, procurement/specification engineers, QA/QC and safety managers, welding workshop supervisors, test laboratories and standards bodies involved in thermoplastics fabrication.
Related standards
- EN 562 - Gas welding equipment: pressure gauges used in welding.
- EN ISO 2503 - Pressure regulators for gas cylinders used in welding, cutting and allied processes.
Keywords: EN 13705:2004, welding of thermoplastics, hot gas welding, extrusion welding, hot gas welding equipment, nozzles, plastification system, preheating system.
