Low Zazzabi Karfe Welding Electrode
W107
GB/T E5015-C2L
AWS A5.5 E7015-C2L
Description: W107 ne a low-zazzabi karfe lantarki da low-hydrogen sodium shafi.Yi amfani da DCEP (tabbataccen lantarki na yanzu kai tsaye) kuma yana iya waldawa a duk wurare.Ƙarfin da aka ajiye har yanzu yana da tasiri mai kyau a -100 ° C.
Aikace-aikace: Ana amfani da shi don walda ƙananan zafin jiki kamar 3.5Ni.
