ʻO ka haku ʻana i kāumīkini wiliwili wahi'o ia ho'i ka 'ike i ka lawelawe 'ana i nā metala like 'ole. ʻO kēlā me kēia mea, mai ke kila kila a hiki i ke alumini, e koi i kahi ala kūikawā no nā welds ikaika a maʻemaʻe. Eia ke alakaʻi kūpono no ka wiliwili ʻana i ʻehā metala maʻamau.
Kūleʻa Kūleʻa: Manaʻo Heat Control
He haʻahaʻa ko ke kila kila a hoʻopaʻa i ka ikaika i nā wela kiʻekiʻe, pono e mālama pono i ka wela.
1. Nā hoʻonohonoho kī:E hoʻohana i ka manawa haʻahaʻa (8–10 kA) a me ka manawa weld pōkole (15–30 ms).
2.Electrode Manaʻo:E ho'ohana i ka dome-type chromium zirconium copper electrodes.
3. ʻenehana:Hiki i ka hana ʻelua-pulse ke hoʻonāwaliwali i ka ʻāpana weld, e hōʻemi ana i ka pōʻino.
Aluminum: Kiekie o keia manawa & wikiwiki
Lawe ʻo Aluminum i ka wela me ka wikiwiki a hoʻokumu i kahi papa oxide resistive, e kāhea ana i kahi hana ikaika a wikiwiki.
1. Nā hoʻonohonoho kī:ʻO ke au kiʻekiʻe (hiki i ka 20–30 kA) i ka manawa pōkole loa ( E emi a i ʻole like me 100 ms).
2.Electrode Manaʻo:E hoʻohana i nā mea uila -nui radius maka me ka hoʻolili wai ikaika.
3. Prep Work:E hoʻomaʻemaʻe i ka ʻili ma mua pono o ka wili ʻana no ka wehe ʻana i ka papa oxide.
Copper & Alloys: Hoʻohuihui i ka ikehu
He mea paʻakikī ka hoʻopaʻa ʻana i ka wela i ka nui o ka conductivity o ke keleawe.
1. Nā hoʻonohonoho kī:Kiʻekiʻe kiʻekiʻe, kālele i kēia manawa; manawa weld pōkole.
2. Pono ka mīkini:Ka -frequency DCmīkini wiliwili wahikūpono no ka puka makani paʻa.
3.Electrode mālama:E mālama i nā wahi pili electrode maʻemaʻe e pale i ka pipili.
ʻO ke kila māmā: ke kaʻina hana maʻamau
ʻO ke kila kalapona haʻahaʻa ka mea maʻamau a kala ʻia no nā mīkini wiliwili kiko.
1. Nā hoʻonohonoho kī:ʻO kēia manawa kūpono (e laʻa, 8–10 kA) a me ka manawa (e laʻa, 3-5 mau pōʻai).
2. Pihi:E hoʻohana i ka ikaika electrode lawa e hana i kahi nugget paʻa me ka ʻole o ka kipaku ʻana.
Ka hopena
A mīkini wiliwili wahihe maʻalahi, akā, pili kona holomua i ka hoʻololi ʻana i nā pono o kēlā me kēia metala. Ma o -hoʻoponopono i nā ʻāpana a me ka hoʻohana ʻana i nā electrodes kūpono, hiki iā ʻoe ke loaʻa nā hopena maikaʻi loa ma waena o ke kila kila, aluminika, keleawe, a me ke kila māmā.
