We design and manufacture various torches for gas welding and brazing applications. These torches are basically required for “Quick” welding of copper tubes in the refrigeration and air conditioning industry.
Generally, in a line production of refrigerators and air conditioners, the gas welding operator is allocated a maximum time of 3-4 secs per joint. In a single nozzle type gas welding torch, the operator has to revolve the torch flame around the job (atleast 200° angle) for uniform heating and filler metal application. This makes the job very cumbersome for the operator where the rear part of the component to be welded may be inaccessible for turning the torch around. Also, it does not ensure 100% filler metal deposition in these areas and provokes lot of rejections and re-work during pressure test. |
