Me ka hoʻomohala wikiwiki ʻana o nā loina kemika a me ka ikehu, hoʻohana nui ʻia nā pahu mālama kila stainless a me nā ipu i ka lawe ʻana a me ka mālama ʻana i nā mea kemika, nā meaʻai a me nā mea inu, ka ikehu a me nā mea ʻē aʻe. Ma muli o kona ʻano haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me ke kūpaʻa corrosion maikaʻi, hoʻohana nui ʻia ke kila stainless austenitic i ke kūkulu ʻana i nā pahu mālama cryogenic, nā mea hana a me nā hale cryogenic nui.

2.Brief hoʻolauna o kā mākou -196 ℃ haʻahaʻa wela hopena kuhiliʻole wiliwili consumables

3. ʻO kā mākou electrode GES-308LT (E308L-16)
I mea e hoʻokō ai i ka noi o ka mākeke, ua hoʻomohala kā mākou hui i nā ʻano like ʻole o ka wela haʻahaʻa haʻahaʻa, nā electrodes stainless steel austenitic toughness kiʻekiʻe, ke ʻano kemika o ka metala i waiho ʻia (e like me ka hōʻike ʻia ma ka Papa 1) a me nā waiwai mechanical paʻa (e like me ka hōʻike ʻana ma ka Papa). 2), a loaʻa i ka maikaʻi loa-kūlana hoʻoheheʻe kaʻina hana, a me ka maikaʻi haʻahaʻa haʻahaʻa hopena hopena toughness, ka hopena o kona nui ferrite ma ka hopena waiwai (Papa 3).

4. Hōʻike i ke kaʻina hana kuʻi (φ3.2mm)
ʻO ke kuʻi pololei ma mua a ma hope o ka wehe ʻia ʻana o ka slag (DC+)
ʻO ke kuʻi ʻana o ka paipu ma mua a ma hope o ka wehe ʻana i ka slag (DC+)
4. Hoʻomaʻamaʻa no ka wili kuʻi
1. Pono e hoʻohana ʻia ka wiliwili haʻahaʻa;
2. E mālama i ke arc ma kahi haʻahaʻa;
3. I ka wa e kowali ai ke arc ma na aoao elua o ke awawa, e oki no kekahi manawa, a e hoomaluia ka laula kowali iloko o 3 manawa o ke anawaena o ka electrode.
5.Pipeline kiʻi o welding consumables noi
No ka -196 ℃ hopena haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa wiliwili kila consumables, ma hope o nā makahiki o ka noiʻi a me ka hoʻomohala ʻana o ka welding consumables, ua loaʻa iā mākou ke kākoʻo ʻana i nā mea hoʻohana wiliwili no nā koʻokoʻo wili, nā cores paʻa, nā cores flux a me nā arcs submerged, a ua hoʻomohala i ka lima electrode arc mau. welding consumables no nā kūlana a pau wiliwili , a he nui 'enekinia noi hoʻokō 'ia, hoʻokipa nā mea kūʻai mai e kuka a koho!
