 WELDING FLUX                                                                                                 


Welding Fluxe is also called aluminium heat welding powder.Use proper exothermic fluxes to make the connection joints more solid and extend the using life.

                                                                Properties of joint



Technology index


Resistance of conductor (Including joint) should be less than that of same length base metal



Joint strength should not less than 95% of low limit of raw material's strength (CCS material is regarded as pure copper )

High melting point

≥1 083 ℃


No air hole ,residue and crack

Section quality


The max size anywhither should be higher than 1/3 of the thickness(or 1/4 of diameter) ,but should be less than 3mm

Advantages of welding powder                                                                          


1, Current carrying capability from welding point is same as conductor with good conducting performance. After inspection, the DC resistance ratio and change rate
are almost zero before and after welding. This is the level that any of the traditional
welding method cannot be compared


2, No need of resources from outside. It can be operated indoor and outdoor


3, It won't be damaged by surge current. The test shows the conductor will be melted
earlier than welding points when under high current impact in short period
4, Corrosion or slack will not be produced from welding. As it is weld junction,no
contact surface, no residual stress, junction is stable and reliable as long term
conductive body
5, As it is welding junction, connector and conductor are combined on molecular.So
it has a good mechanical strength and is a permanent junction
6, Equipment is simple, convenient and handy. The operation is easy and can be done
without professionals  

OPERATION INSTRUCTION                                                                                       


  Check to ensure the graphite mold and conductor is clean ,no residue before making the connection


  Use a propane torch to dry wire conductors and remove remaining cleaning residue, solvent, or water before making the connection.


  Close the graphite mold lid before ignition ,and close the lid tightly


  Insert the conductors and position them for the connection.Ensure them in the center of cavity.


  Keep the irrelevant personnel 1.5M away when welding


  Keep the inflammable goods 1-2M away when welding


  The operator must be equipped thermal barrier glove


  Don't face to the mould opening when welding


  The operator keep 1.5M away mould is must after ignition


  Don't touch the mould and connected parts directly after welding


  Open the mould and take the joint out with wrench 10-20S later after reaction .


  Insulate the joint after the conductor cooling completely .
