NĀ PALAPALA:

Welding o 9% Cr-1% Mo kila a me 9% Cr - 2% Mo kila i hoʻohana 'ia no ka uila mana a me kiʻekiʻe puʻe moku.

NĀ HOʻOAKAʻI:

PA-8016-B8 mea he haʻahaʻa hydrogen electrode nona weld metala i loko o 9%Cr-1% Mo.Hoʻolālā ʻia ia no ke kila wela a me nā kila no nā lawelawe hydrogen wela, ʻoi loa i ka ʻoihana petrochemical.Hiki ke ʻae ʻia ka electrode no kona ikaika tensile kiʻekiʻe, paʻakikī maikaʻi a me ke kūpaʻa wela nui.

NĀ MANAʻO NO KA HOʻohana:

1. E hoʻomaloʻo i nā electrodes ma 350-400 ° C no hoʻokahi hola ma mua o ka hoʻohana ʻana a mālama i nā electrodes ma 100-150 ° C ma hope o ka hoʻomaloʻo ʻana iā lākou me ka nānā ʻana e pale i ka makū.

2. E hoʻohana i ke ʻano hoʻi i hope a i ʻole e hahau i ke arc ma luna o kahi pā kila liʻiliʻi i hoʻomākaukau ʻia no kēia kumu i mea e pale aku ai i nā pū i ka hoʻomaka ʻana.

3. E mālama i ke arc i ka pōkole e like me ka hiki.

4. E hoʻomoʻa mua i ka 100-150 ° C.ʻOkoʻa ka mahana e hoʻopili ʻia e like me ka mānoanoa pā a me ke ʻano o ke kila e welded.

5. E makaʻala ʻaʻole e ʻoi aku ma mua o ka hoʻokomo wela kūpono no ka mea ʻoi aku ka nui o ka wela-hoʻokomo ʻana ke kumu i ka emi ʻana o nā waiwai hopena a me ka ikaika o ka hoʻoulu ʻana o ka metala weld.
