5. Noi:
1) Kūlana: EN10028 EN10222-2 2017 (European standard, haole)
2) Ka inoa: Ua kapa ʻia e like me ka ʻike o C (carbon) a me Mo (molybdenum), ʻo ia hoʻi, ʻo ka ʻike kalapona.
ʻO kēia pā kila ma kahi o 160, aʻo ka ʻike o ka molybdenum ma kahi o 300.
3) Hoʻomaʻamaʻa wela: normalizing a normalizing + tempering
4) He ʻokoʻa ka 16Mo3 mai nā mea ʻē aʻe i ka wā wili. Pono e hoʻomehana mua ʻia, a mālama ʻia ka weld no
ma kahi o 30 mau minuke ma hope o ka pau ʻana o ka wili.
5) ʻO 16mo3 kila manganese he mea hoʻohui koʻikoʻi i loko o ke kila a me kahi mea paʻakikī koʻikoʻi, nona ka
ka hopena nui i ka paʻakikī o ka metala weld.
6) Ke emi iho ka Mn o ka 16mo3 ma lalo o 0.05%, he kiʻekiʻe loa ka paʻakikī o ka weld;
7) He palupalu loa ka pā kila 16mo3 ke ʻoi aku ka Mn ma mua o 3%;
8) I ka Mn maʻiʻo o 16mo3 pā kila he 0.6-1.8%, TEL: 180-377-99127% weld metala i ʻoi aku ka ikaika a me ka paʻakikī.
9) He aha ka hopena o ka sulfur (S) element o ka pā kila 16mo3 i ka weldability?
10) Loaʻa pinepine ʻia ka Sulfur ma ke ʻano o ka hao sulfide i ke kila, a ua puʻunaue ʻia ma ka palena o ka palaoa i loko o kahi pūnaewele, no laila nui loa.
e hoemi ana i ka paakiki o ke kila. He haʻahaʻa ka mahana eutectic o ka hao a me ka hao sulfide (985°C). No laila, i ka wā hana wela,
ʻO ka mahana hoʻomaka o ka hana ʻana he 1150-1200 ° C, a ua heheʻe ka eutectic o ka hao a me ka hao sulfide, ka hopena
māhā i ka wā e hana ai. ʻO kēia hanana ka mea i kapa ʻia ʻo "hot brittleness of sulfur". ʻO kēia waiwai o ka sulfur ke kumu o ke kila
hoʻomohala i nā māwae wela ke wili ʻia. No laila, ʻo ka maʻiʻo o ka sulfur i loko o ke kila e hoʻopaʻa pono ʻia. ʻO ka ʻokoʻa nui ma waena
ʻO ke kila kalapona maʻamau, ke kila kalapona kiʻekiʻe a me ke kila kila kiʻekiʻe ka ʻike o ka sulfur a me ka phosphorus.
