What is Hot Wedge Welding and it’s Working Principle?

What is wedge welding and it’s Working Principle

Wedge welding machine which is developed by JC tool. it is applicable for welding various plastic materials, such as LDPE (Low-density polyethylene), (Polyvinyl chloride (PVC), HDPE (High-density polyethylene), Ethylene-vinyl acetate (EVA), Polypropylene (PP) and many other materials, The speed of wedge welding equipment such as JC-1800-DTM GEOMEMBRANE WEDGE WELDER, JC-1800-ZTM GEOMEMBRANE WEDGE WELDER

JC-800-XTM GEOMEMBRANE WEDGE WELDER is very high and efficient which save our time. JC tool is only company which have latest plastic welding equipment providing high quaily experience especially when it comes to our new wedge welding products.

 

Application of Wedge Welder

wedge-welding

Wedge welding has excellent performance and it’s environmentally friendly. It has been widely used in engineering products.

It’s is used in various projects. As we mentioned earlier it has been widely used in engineering projects such as:

  • Expressways
  • Tunnels
  • Reservoirs
  • Waterproof
  • Construction
  • Main Components of wedge welding
  • Pressure handle
  • Manipulate hand
  • Speeding knob
  • Speed switch
  • Electric machine insurance
  • Temperature switch
  • Power supply insurance
  • Temperature control instrument
  • Control case
  • Thermal wedge
  • Pressure wheel
  • Creeping wheel
  • Sway head
  • Adjusting Nut

Working Principle of Wedge Welding

Electric machine carried with above and below pressure wheel and turn it through
a speed-slow box and chain steel, and heating the bracket up and turn thermal wedge
to plug in between the two main materials, meantime let the pressure bracket press
Operating Criteria
Notice: In order to obtain the excellent quality 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 to 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 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 wedge welding temperature: it can be directly watched the
transparency PE material.If the wedge welding mark is lever-off with transparency 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 side .And to the non-transparence material, it also can be tested by resistance pull after the whole party is cooled down
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 wedge 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 wedge welding.

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

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