Kiekie manganese kila surfacing electrode D256 AWS: EFeMn-A

ʻO ke kila manganese kiʻekiʻe i luna electrode D256 AWS: EFeMn-A

NĀ PALAPALA:

He kūpono ia no ka hoʻoheheʻe ʻia ʻana o nā mea crusher, kiʻekiʻe manganese rail, bakeke, bulldozer, etc.

NA ANOAI:

ʻO THD256 ka electrode i luna o ke kila manganese kiʻekiʻe me ka haʻahaʻa hydrogen potassium coating. Hiki ke ac a me ka dc (ac welding, ʻaʻole haʻahaʻa ka uila ʻole ma lalo o 70V), pono ke hoʻohana ʻana i ka welding liʻiliʻi liʻiliʻi, ke kuʻi ʻana i ka ʻulaʻula. ʻO ka hāmare koke a i ʻole ka wai kinai ʻana, i mea e hōʻemi ai i ke ʻano o ka māha.

NĀ MEA:

1. Ma mua o ke kuʻi ʻana, e kālua ʻia ka electrode ma 300-350 ℃ no 1 hola ma mua o ka hoʻohana ʻana.

2. No ka hoʻoheheʻe ʻia ʻana o nā ʻāpana ʻeleʻele o ke kila manganese kiʻekiʻe, e hoʻoneʻe ʻia ka papa luhi a mālama ʻia me ka paʻakikī wai a i ʻole e kūʻai ʻia me ka chromium manganese steel electrode (e like me D277).

3. Ma muli o ka nui o ka uahi melemele i ka wā o ka hoʻoheheʻe ʻana i luna, pono e uku ʻia i ka hoʻoikaika ʻana i ka ea a me ka hana ʻana ma ke kūlana makani.
