Learning for Air conditioning and refrigeration gas welding

   Air conditioning and refrigeration gas welding.

For Air conditioning and refrigeration welding you need a welding plant and also solder rod.
 (Copper welding Rods), brass rod and flux.
 For welding  copper pipe to copper pipe you need a solder rod.
When we weld iron pipe with copper pipe, we need brass rod.
When we weld iron pipe with iron pipe ,we need brass rod.
 Flux is very essential for best and perfect welding .

Compressor and Refrigerator has copper pipe so we weld it with copper rod.
                                                                          (see below picture 1)
                                                                                           1

            In picture no 2 both pipes are coppers so it weld with solder rod .
                                                                                     2

           In picture no 3 all pipes are coppers so it weld with solder rod .
                                                                                    3

In picture no 4 all pipes are coppers so it weld with solder rod .
                                                                                           4

In picture no 5, compressor pipes and refrigerator's condenser pipes are iron.
 Return pipes of refrigerator are copper. Compressor, condenser and filter's joints will weld with brass rod.
 Filter and capillary's joint will weld with solder rod .
 Before welding enter the capillary in filter at least 5mm otherwise capillary pipes will block.                                                                                                    5             

 In picture no 6 both pipes are iron so it weld with brass rod.

 In picture no 7 homemade flux is used .(suwaga powder)
                                                                                         7
