Procedure of Soldering the Joint

Procedure of Soldering the Joint Points : Procedure of Soldering the Joint, Soldering the Joint, Procedure Taping the Splice Soldering the Joint The mechanically bound made earlier cannot be said to be mechanically secure. In order to make is necessary to solder the joint. The soldering can be done either with the help of a soldering iron or by means of a blow lamp. Before soldering it is essential to clean the surface and to make it free from dirt. grease etc. Now apply soldering paste around the joint both at the top and bottom of it. The application of soldering paste is not necessary if resin-core solder is used which acts as a flux. Now heat the joint with the help solder is used which acts as flux. Now heat the joint with the help of a blow lamp heating it with the tip of the flame. It is essential to heat the joint up to a proper temperature: if it is not properly heated, proper soldering cannot be done, and it if the joint is over-heated, proper soldering cannot be done, and if the joint is over-heated the conductor is weakened and becomes brittle. The proper temperature is tested with a piece of solder wire, which when placed over the joint should melt. At that instant, apply solder over whole of the joint as shown in Fig. The solder should be applied several times until the solder floats or runs completely through the splice.

Procedure Taping the Splice The soldered joint must now be provided with an insulation, the thickness of which must be equal to that on the wire. For the wires generally used for house-wiring purpose rubber tape, friction tapes and black tape should be used. The method of applying the rubber tape is shown in Fig The tape should half overlap the previous turn, and the type should be stretched is hit until whole the joint is covered and a hit of the insulation of the ether wire is also covered. Now apply friction tape in a similar fashion to that of rubber tape.
