Secondary ledeburite formation during various welding techniques
The occurrence and formation sequence of secondary ledeburite in the heat affected zone of chromium ledeburitic tool steel W.Nr. 1.2379 (OCR12 VM) after welding with SAW, TIG, microplasma and laser welding techniques is presented in this paper. Special attention was paid on the behaviour of...

| description | The occurrence and formation sequence of secondary ledeburite in the heat
affected zone of chromium ledeburitic tool steel W.Nr. 1.2379 (OCR12 VM)
after welding with SAW, TIG, microplasma and laser welding techniques is
presented in this paper. Special attention was paid on the behaviour of
carbides. The occurrence of secondary ledeburite is a result of local
enrichment of the austenite matrix with alloying elements, due to partial or
complete dissolution of primary/eutectic carbides. The results show that the
largest amount of secondary ledeburite is formed during submerged arc
welding, followed by TIG and microplasma welding technique. Welding by laser
technique, with appropriate technological parameters, could prevent secondary
ledeburite formation. |
