Thanks for the response, im new to high carbon steels, does the sparking mean the hc steel it's ruined or can i try to weld again using the 2 pieces that split apart and still makes a decent tool it of it

Hi guys! Just picked up a bulk find of files from an antique shop some nicholson, simmonds and a few other i cant remember at the moment at less then a Buck a piece, figured I'd try to practice forge welding with them. So i ground all the teeth off a nicholson cut it in half, tac welded it and threw a handle on it and dumped it into a strictly coke fire. First heat went fine, seemed to stick together but after second heat i went to hit it and it simply cracked in half and sent top half of "billet" flying! Any knowledge of why this happened would be greatly appreciated. Area where it cracked was very slightly sparking after i pulled it out of forge. Thanks guys!
