1. A flame coating machine configured to coat a field joint of a pipeline, the flame coating machine comprising:
a flame spray system comprising a flame spray unit configured to at least one of: (i) heat an annular junction portion and two annular end portions of an applied coating that delimits the annular junction portion, and (ii) coat the annular junction portion and the two annular end portions with a thermoplastic polymer; and
a control system comprising:
a temperature sensor configured to acquire a plurality of temperature values along a surface defined by the annular junction portion and the two annular end portions,
a control unit configured to actuate, based on the acquired temperature values and at least one threshold value, the flame spray unit in one of: a polymer flame spraying mode and a flame heating mode,
a first position sensor configured to acquire a position of the flame spray unit with respect to the surface, and
a second position sensor configured to acquire a position of the temperature sensor with respect to the surface.
