Can .ts audio files be combined using cat command in append mode to get the .mp3 file

I have some .ts files as part of an hls audio stream. Can I use the cat command to append them and get the .mp3 file. I'm curious what ffmpeg does to create the mp3 from .ts or .m3u8 files so that I can implement it in a node server

No. If you just concatenate them the result is still a MPEG-TS container file, i.e. basically a sequence of 188-byte TS packets. What you need is a MPEG-TS demuxer which would turn (decapsulate) the TS into a sequence of MP3 audio frames [1], more generally speaking the audio elementary stream.
