Solution

Oxy-hydrogen flame is composed of oxygen and hydrogen, which burns at a very high temperature.
The oxy-hydrogen flame is used for cutting and welding metals due to the heat that is produced by the flame (the very high temperature that is $2800 ° C$ ).
At such a high temperature the metal gets melted easily and hence it can easily be cut apart or welded together.
