GEH-507 ndi electrode yamanja yogwirizana ndi GB/T984 EDCr-A1-15 yogwiritsidwa ntchito ku ma valve ndi zisindikizo zina. Imasinthasintha kwambiri ndi kutentha kwa malo ogwira ntchito pansi pa 450 ℃. Pamsika, kugwiritsa ntchito mankhwalawa ndikofalikira komanso kutchuka. Atha kugwiritsa ntchito DC reverse surfacing high chromium chitsulo, pamwamba zitsulo 1Cr13, chromium martensitic chitsulo. Pansi pa ulamuliro wathu okhwima khalidwe mankhwala ndi luso kupanga, yobereka chiphaso mlingo wa mankhwala ndi mkulu kwambiri. Ife kupanga 3.2mm, 4.0mm, 5.0mm molimba pamwamba amavala zosagwira dzanja maelekitirodi makasitomala, ndi kuthandizira mankhwala mwamakonda.
