ANA IYA AMFANI DA WANNAN ELECTRODE MAI SURFAACING ELECTRODE DOMIN LINING SLEVE OF SHAFT SEEVE, YANKE GEFE NA KAYAN FIBER NA CHEMICAL, SAWTOOTH, SCROW PUSH ROD, HIGH zafin jiki da HIGH matsa lamba bawul DA HIGH matsa lamba ETC. Rashin ƙarancin aikin aikin ya kamata ya zama ƙasa da Ra12.5μm, kuma ya kamata a cire tsatsa, mai da sauran datti sosai. Matrix kada ya kasance yana da fasa, pores, yashi da sauran lahani, kuma gefuna da sasanninta ya kamata a zagaye. Kafin surfacing, ya kamata a zaɓi yanayin zafi daban-daban bisa ga kayan da ake amfani da su don preheating. Lokacin da matrix abu ne pearlitic zafi-resistant karfe ko martensitic bakin karfe da sauran kayan da matalauta waldi yi, da austenitic bakin karfe surfacing Layer ya kamata a welded a kan matrix surface, sa'an nan da cobalt tushen gami ya kamata a surfacing bayan m aiki zuwa ga. inganta tsattsauran ra'ayi kuma ku guje wa fasa. Ko dai AC ko DC baka walda wutar lantarki za a iya amfani da D802 da D812 electrodes. Ana ba da shawarar samar da wutar lantarki na walda DC.
