                                                                    Soldering
Date:-19 sept 2017

Aim:-to learn to solder solderning

Requirements:-Blow lamp, pilier, soldering iron, hydrochloric acid, soldering rod, (lead,zinc,tin) tin sheet plate for making tin can copper cube glass flux.

procedure:-1) Take one glass and added hydrochloric acid.
                   2) Copper cubes is placed in the flame of blow lamp for heating.
                 3)Apply flux on the area to be soldered.
                 4) solder metal is kept on the area to be soldered. It is heated using red hot copper cube. solder metal. It solidifies to make perfect soldered joint

Observation:-1)Why flux is used for soldering.
                      2) Why acid is used to make flux

Conclusion:-1)a metal whose melting point is below the melting point of a job is used to join the job.
                    2) Soldering is used to solder job for less thikness
                    3) It can be done with less heat
                    4) Easy to do procedure.

Threading and Tapping

                               

 DATE:-20 August 2017

  Aim:-To learn about treading and tapping  

    

   Requiremeant's:- Take a bar of range 18mm to 12mm oil,treading die and use of pipevice.

  Procedure:-

                       Threading:-Fit rod in to the vice use of die range to threading give back to forth motion to the die use of oil for lubrication.

Tapping:-Drill hole of proper size on the job .It is important to calculate size of hole required. As light drill can be made to fit the tap range .It is just over size then the dai-meter  of hole ,deep of the cut is smaller with this tap range . oil is used for lubrication and cooling when aware we rotate we use oil. No tightly rotate because of that oil is to use to smoothly rotate.

     Conclusion:-Taps and die's are cutting tool's used to creat
