H00Cr21Ni10T Uea kuʻihao Argon-arc
Palapala noi
Nui no ka CNG (compressed natural gas), LNG (liquefied natural gas), LPG (liquefied petroleum gas) ikehu kahua no ka welding stainless steel mea hoʻohana i ka cryogenic a me ka haʻahaʻa wela kaiapuni;e like me 12Cr18Ni9 (SUS 302), 06Cr19Ni10 (SUS 304), 022Cr18Ni9 (SUS 304L) ) wiliwili.

ʻO ka mālama ʻana no ka hoʻohana ʻana i ka huahana
1. kinoea pale: maemae Ar;kahe kahe: 9-14L / min i ka manawa o 100-200A, 14-18L / min ke 200-300A ka manawa.
2. Tungsten electrode hoʻonui lōʻihi: 3-5mm;arc lōʻihi: 1-3mm.
3. Ua kaupalena ka makani makani i ≤1.0m/s;ʻōlelo ʻia e hāʻawi i ka pale argon ma ke kua o ka wahi wili.
4. I ka welding, pili pono ka nui o ka ikehu laina kuʻihao i nā waiwai mechanical a me ke kūʻē ʻana o ka weld metala, a pono e uku ʻia ka nānā ʻana iā ia.
5. E hōʻoia i ka weheʻana i ka'ōpala o ka'ōpala, ka wai, kaʻaila, ka lepo, a me nā mea'ē aʻe ma ka'āpana wili.
ʻO nā ʻōlelo aʻoaʻo ma luna nei no ka ʻike wale nō, a e lanakila ke kūlana maoli i ka hana kikoʻī.Inā pono, pono e hoʻokō ʻia ke kaʻina hana ma mua o ka hoʻoholo ʻana i ka hoʻolālā welding.
