Hardfacing WeldingElectrode
Maemo: DIN 8555 (E9-UM-250-KR)
Nomoro ea mofuta: TY-C65
Tlhaloso & Tšebeliso:
· Electrode e khethehileng e nang le welding e nepahetseng le thepa ea mochini.
· Austenite- Ferrites weld tšepe.Maemo a phahameng a matla le khanyetso e phahameng ea crack.
· Haholo-holo e loketse ho kopanngoa ka litšepe tse thata haholo, ha ho etsoa litlhoko tse phahameng ka ho fetisisa holim'a seam.
· Ho hanyetsa crack ho hoholo ha o kopanya litšepe tsa motsoali tse thata ho cheseha, joalo ka litšepe tsa austenitic le ferritic, litšepe tse phahameng tsa manganese tse nang le litšepe tse kopantsoeng le tse sa tsoeng, tse pholileng mocheso le litšepe tsa lisebelisoa.Likopo tsa tokiso le tlhokomelo ea mochini le likarolo tsa koloi hammoho le tokisong ea lisebelisoa.
· Joalo ka mosamo lera holim'a lisebelisoa tsena e boetse e ka tsela e loketseng loketseng.
