Engineering Architecture of EXWELD Handheld Extrusion Welders

Handheld extrusion welders of the EXWELD series by German manufacturer WEGENER Welding provide reliable extrusion joining for industrial sheets, tanks, and pipelines fabricated from polyethylene, polypropylene, and fluoropolymers.

The core functional assembly includes a specialized 3-zone plasticizing screw delivering uniform melt homogeneity from welding rod or polymer granules without polymer thermal degradation.

The onboard microprocessor controller continuously samples heating barrel temperatures, providing digital cold-start motor interlocks until melt thresholds are reached.

Interchangeable PTFE welding shoes enable precise filleted, butt, and corner seams with stepless melt feed rates scaling up to 6.0 kg/h for continuous structural tank fabrication.

Precision Hot Gas Regulation in Duratherm and Autotherm Tools

Hot air plastic welding tools of the Duratherm3 and Autotherm4 series by WEGENER Welding deliver manual welding, tacking, and preheating for thermoplastic components in field and workshop environments.

Autotherm4 features closed-loop digital temperature regulation to compensate for mains voltage variations and airflow fluctuations. Operators set temperatures under continuous monitoring according to polymer material specifications.

Versions with integrated air blowers (Duratherm3 SC2 and Autotherm4 SC2) incorporate durable brushless drive motors. External air models connect to industrial air supplies via DT 6L blower units, delivering continuous particle-free dry airflow to the plastic fusion area.

Heated Tool Butt Fusion Welding for Plastic Sheets under DVS 2207

Sheet butt welding machines of the SM and ST series by WEGENER Welding implement heated tool butt fusion joining for thermoplastic boards in accordance with rigorous DVS 2207 industrial fabrication codes.

The sequence controls heating element contact, low-pressure heat soaking, rapid tool retraction, and joining under controlled hydraulic pressure followed by cooling.

The non-stick PTFE coated heating swords feature multi-zone temperature monitoring within a 1 °C margin across operating spans up to 6 meters.

Synchronized hydraulic carriage cylinders guarantee parallel clamping alignment, preventing residual stresses across thick polyolefin and fluoropolymer sheet assemblies.

Thermal Bending and Folding Principles of BV and BM Machines

Thermal sheet bending machines of the BV x06 and BM x06A series manufactured by WEGENER Welding produce precise straight-line bends on thermoplastic sheets with thicknesses ranging from 2 up to 30 mm.

Sheets are clamped by pneumatic hold-down beams while upper and lower heating swords soften the polymer along the designated fold line. A pivoting folding beam rotates the workpiece through angles from 0° up to 95°, continuously monitored by a high-resolution angular encoder.

The automated controller of BM x06A stores heating and holding parameters for repetitive series manufacturing of rectangular chemical storage tanks and ventilation ductwork.
