Electrode welding paʻakikī
Kūlana: DIN 8555 (E6-UM-60)
ʻAno ʻAno: TY-C DUR 600
Hōʻike a me ka noi:
· Kelepona SMAW i uhi ʻia no ka ʻili ʻana o ka ʻili.
· Kūleʻa maikaʻi i nā koʻikoʻi kaomi a me nā hopena.
· E pili ana i ke ao holoʻokoʻa no ka hoʻopili ʻana i nā ʻāpana o ke kila, ke kila hoʻolei a me ka Mn-steel kiʻekiʻe, e pili ana i ka abrasion, ka hopena a me ke kaomi.ʻO nā kahua noi maʻamau ka ʻoihana hoʻoneʻe honua a me ka ʻoihana lapaʻau pōhaku, e laʻa me nā niho excavator, nā pahi ʻeke, nā ʻāwae crusher a me nā cones, nā hāmare wili, etc.
Hoʻohui kemika o ka metala i waiho ʻia(%):

Nā ʻano maʻamau:
· Microstructure Martensitic
· Maikaʻi maikaʻi me ka Tungsten carbide nā mea hana
· Preheating E hoʻomaʻamaʻa mua i nā ʻāpana kaumaha a me nā kila kiʻekiʻe-tensile i 200-350 ℃
· Hoʻomaʻa hou i ka Redry no 2 mau hola ma 300 ℃ ma mua o ka hoʻohana ʻana.
