What is Geomembrane Wedge Welder

What is Geomembrane Wedge Welder?


Geomembrane wedge welder machines utilize a warmed component to intertwine thermoplastic sheet materials. Wedge welders are programmed machines that keep running between two covered sheets of material. … Wedge welding is most generally performed on HDPE sheet materials, however, JC Machinery tools Inc. has what it takes to weld most thermoplastic geomembrane materials.

Operating Criteria of Wedge Welder

Notice: In order to obtain the excellent quality (Geomembrane Wedge Welder)and high efficiency, it should be
manipulated by professional people since the welding quality of the machine has
a direct relationship with the enactment of speed and temperature.

1. The user must choose the three holes receptacle with earthing and confirm
the good connection of exterior wire. Pick the pressure to handle up to separate
the up and down iron wheels and then plug the power supply on.
2. Switch power supply on, and choose suitable temperature (Temperature
adjusting diagram – literature) and speed. Then pick some narrow material to
weld for a try and make sure the best effect. Owing to the difference between
the environmental temperature and the thickness of material, the welding
temperature of the same material could be different. We can choose to a
referenced speed (about 1.5m/min) when selecting the temperature. And then
slowly adjust the temperature from low to high, about from 250℃ to 400℃
(482 to 752℉)

3. The estimation of the welding temperature: it can be directly watched the
transparence PE material.If the welding mark is lever-off with transparence glass
status, it showed that the temperature and the speed is suitable; if the welding
mark is seriously broken up, it showed that the temperature is too high or the
speed is too low; If the welding mark is not transparency with white status, it
showed that the temperature is on the slow side or the speed is on the fast

4. Mending the edge of the welding material smooth.The surface face of the front
side, and overlap to left down and right up.The width of pulled up is 120mm.

5. Plug the welding material between the two iron wheels to make the parallel
between the body of the machine and the edge of mother material, and it can
weld itself after confirmed the temperature and the speed. Usually, the operator
just watches the warp between the welding mark and the edge of the mother
material and timely rectify it within a small scope.At the end of material welding,
pick up the handle to separate the up and down iron wheels.

6. Owing to the thermal inertia, it can adjust the temperature within the small scope
to offset the discrepancy in temperature if it comes too high or too low in the
process of welding.

7. In the process of welding, it can adjust through the two interior hexangular
screws on the swaying head if the welding mark is not equality in two outside.
(Just the corresponding screw in the upside of intensive welding deep or in the
upside of loosen welding mark shadow)

8. Welded material crossed with another material in the shape of “T”. The ways of
welding is as the diagram below. Cut the crossing head sticking to the thermal
wedge off 12cm inclined.


Please clean the dunghill in the thermal wedge and the mud in the chain guard and
oiled the whole machine to the dry place when not using it.

The adjustment of the Pressure Wheel
According to the various thickness of material, it can be adjusted the magnitude of
pressure by switching the modulated screw (wedge welder). It will increase by clockwise, and it
decrease by anticlockwise.
