ʻIkepili Sila MIG ER70S-G nā kila Carbon kiʻekiʻe
He kūpono no ka hana moku, ke alahaka, ke kūkulu ʻana a me ka ʻeli ʻana i nā noi, i hoʻohana ʻia i ka welding manamana lima kiʻekiʻe o kēia manawa, ka hoʻopili ʻana a me ke kuʻi kea.
ʻO ka maʻamau a mākou i hālāwai ai: GB/T8110 G 49A4 C1/M21 S11 N , AWS A5.18 ER70S-G & A5.18M ER49S-G, ISO14341-A:G 42 4 C1/M21 Z4Si1, ISO 14341-B:G 4 C1/M21 S11, JIS Z3312 YGW-11/15.
He aha nā
mau ano?
●ʻO ka palekana o ke kaiapuni a me ke olakino, a hiki ke pale i ka hopena maikaʻi ʻole o ke keleawe ma ka maikaʻi o ka welding.
●Ma waho aʻe o nā mea hoʻohui kūpono e like me Si a me Mn, ua hoʻohui ʻia nā mea Ti lawa e hoʻopaʻa i ke arc a hoʻomaʻemaʻe i ka hoʻololi arc.
●Hoʻemi nui ʻia ka nui pili o ka paʻi a me ka uahi.
●Loaʻa iā Ti ke kuleana o ka hoʻomaʻemaʻe palaoa o ka weld pass, no laila e hoʻomaikaʻi nui ʻia ka paʻakikī o ka weld pass, a hiki iā ia ke pāʻani i kāna hana kiʻekiʻe ma ke kahe nui.
