ʻO ka wehewehe: T107 he electrode keleawe maʻemaʻe me ke keleawe maʻemaʻe e like me ke kumu a uhi ʻia me ka haʻahaʻa-hydrogen sodium type flux.E hoʻohana i ka DCEP (direct current electrode positive).ʻO nā waiwai mechanical maikaʻi, maikaʻi ka corrosion kū'ē i ka lewa a me ka wai kai, ʻaʻole kūpono no ka wili ʻana i ke keleawe me ka oxygen a me ke keleawe electrolytic.
Hoʻohana: Hoʻohana nui ʻia ia no ka hoʻopili ʻana i nā mea keleawe e like me nā pahu keleawe conductive, nā mea hoʻololi wela keleawe, a me nā conduits wai kai no nā moku.Hiki ke hoʻohana ʻia no ka hoʻoheheʻe ʻana i ka ʻili o nā ʻāpana kila kalapona kū i ka ʻino o ke kai.
ʻO ka hui kemika o ka weld metala(%):

Nā waiwai mīkini o ka weld metala:
| Mea ho'āʻo | Ka ikaika tensile Mpa | ʻO ka lōʻihi % |

Hoʻolaha:
1. Pono e hoʻomoʻaʻia ka electrode ma kahi o 200 ° C no ka hola 1 ma mua o ke kuʻiʻana, a pono e hoʻoneʻeʻia ka wai, kaʻaila, nā oxides a me nā mea haumia'ē aʻe ma kaʻili o ka weldment.
2. Ma muli o ka thermal conductivity o ke keleawe, a me ka preheating wela o ka lāʻau e welded maʻamau maʻamau kiʻekiʻe, maʻamau ma luna o 500 °C.ʻO ka nui o ke au welding e kūpono me ka mahana wela o ka metala kumu;E ho'āʻo i ka wiliwili pōkole kūkaʻi.Hiki ke hoʻohana ʻia no ka reciprocating linear motion e hoʻomaikaʻi i ka hana weld.
3. No ka lōʻihi o nā welds, e ho'āʻo e hoʻohana i ke ʻano kuʻi kuʻi hope, a ʻoi aku ka wikiwiki o ka wiliwili.
I ka wā e hoʻopili ʻia ai ka multi-layer, pono e hoʻopau loa ʻia ka slag ma waena o nā papa;ma hope o ke kuʻi ʻana, e hāmare i ka weld me kahi hāmare poʻo pālahalaha e hoʻomaha ai i ke kaumaha,
E hoʻomaikaʻi i ka maikaʻi o ka weld.
