Al\u00fcminyum ala\u015f\u0131mlar\u0131n\u0131n kendine \u00f6zg\u00fc fiziksel ve kimyasal \u00f6zellikleri nedeniyle, kaynak i\u015flemi s\u0131ras\u0131nda bir dizi zorluk ve \u00f6zellik ortaya \u00e7\u0131kacakt\u0131r. Al\u00fcminyum kayna\u011f\u0131 yaparken, bu malzemenin \u00f6zel \u00f6zelliklerini g\u00f6z \u00f6n\u00fcnde bulundurmam\u0131z gerekir.<\/p>\n

1. Al\u00fcminyum g\u00fc\u00e7l\u00fc bir oksitleme \u00f6zelli\u011fine sahiptir ve al\u00fcminyum ile oksijen aras\u0131ndaki afinite \u00e7ok y\u00fcksektir. Havadaki oksijenle kolayca birle\u015ferek, kal\u0131nl\u0131\u011f\u0131 yakla\u015f\u0131k 0,1 \u00b5m olan yo\u011fun ve sa\u011flam bir al\u00fcminyum oksit ince tabakas\u0131 olu\u015fturur. Al\u00fcminyum oksidin erime noktas\u0131 2050 \u00b0C'ye kadar \u00e7\u0131kmaktad\u0131r. Bu de\u011fer, al\u00fcminyum ala\u015f\u0131m\u0131n\u0131n erime noktas\u0131n\u0131 \u00e7ok a\u015fmaktad\u0131r ve yo\u011funlu\u011fu al\u00fcminyumun yakla\u015f\u0131k 1,4 kat\u0131d\u0131r.<\/p>\n

Kaynak i\u015flemi s\u0131ras\u0131nda, al\u00fcminyum oksit tabakas\u0131 metallerin birbirine iyi bir \u015fekilde ba\u011flanmas\u0131n\u0131 engelleyebilir ve kolayca c\u00fcruf kal\u0131nt\u0131lar\u0131na yol a\u00e7abilir. Ayr\u0131ca, oksit tabakas\u0131 nemi de emer; bu da kaynak s\u0131ras\u0131nda kaynak diki\u015finde g\u00f6zeneklere neden olabilir.
\nBu nedenle, kaynak kalitesini sa\u011flamak amac\u0131yla, kaynak i\u015flemi s\u0131ras\u0131nda al\u00fcminyumdan olu\u015fan al\u00fcminyum oksit tabakas\u0131 kald\u0131r\u0131lmal\u0131 ve kaynak s\u00fcreci boyunca bu tabakan\u0131n yeniden oksitlenmesi engellenmelidir.<\/p>\n

2. Al\u00fcminyum, y\u00fcksek \u0131s\u0131 iletkenli\u011fine ve \u00f6zg\u00fcl \u0131s\u0131 kapasitesine sahiptir. Al\u00fcminyumun bu iki de\u011feri olduk\u00e7a y\u00fcksektir; \u00e7eli\u011fin yakla\u015f\u0131k iki kat\u0131d\u0131r. Kaynak i\u015flemi s\u0131ras\u0131nda, b\u00fcy\u00fck miktarda termal enerji h\u0131zla ana metalin i\u00e7 k\u0131sm\u0131na aktar\u0131l\u0131r. \u00c7eli\u011fin kayna\u011f\u0131 ise daha fazla \u0131s\u0131 t\u00fcketir.
\nY\u00fcksek kaliteli kaynak ba\u011flant\u0131lar\u0131 elde etmek i\u00e7in, daha y\u00fcksek enerji yo\u011funlu\u011funa ve daha y\u00fcksek g\u00fcce sahip bir \u0131s\u0131 kayna\u011f\u0131 kullan\u0131lmal\u0131d\u0131r.<\/p>\n

3. Al\u00fcminyum, termal \u00e7atlaklara kar\u015f\u0131 y\u00fcksek bir e\u011filime sahiptir. Al\u00fcminyum ala\u015f\u0131m\u0131n\u0131n termal genle\u015fme katsay\u0131s\u0131 \u00e7eli\u011fin yakla\u015f\u0131k iki kat\u0131d\u0131r ve kat\u0131la\u015ft\u0131\u011f\u0131nda hacim b\u00fcz\u00fclme oran\u0131 6,5%\u2019dir. Bu nedenle, baz\u0131 al\u00fcminyum ala\u015f\u0131mlar\u0131n\u0131n kaynaklanmas\u0131nda termal \u00e7atlaklar genellikle a\u015f\u0131r\u0131 i\u00e7 gerilimden kaynaklan\u0131r.
\nTermal \u00e7atlama, k\u0131r\u0131lgan s\u0131cakl\u0131k aral\u0131\u011f\u0131nda meydana gelir ve bu, al\u00fcminyum ala\u015f\u0131mlar\u0131n\u0131n, \u00f6zellikle de y\u00fcksek mukavemetli al\u00fcminyum ala\u015f\u0131mlar\u0131n\u0131n kaynaklanmas\u0131nda en s\u0131k g\u00f6r\u00fclen kusurlardan biridir.
\nD\u0131\u015f kusurlar\u0131 veya deformasyonu \u00f6nlemek i\u00e7in, kaynak yaparken y\u00fcksek \u0131s\u0131tma ve so\u011fuma h\u0131zlar\u0131na dikkat edin. Kal\u0131n veya b\u00fcy\u00fck par\u00e7alar\u0131 kaynaklarken, levhay\u0131 \u00f6nceden \u0131s\u0131t\u0131n ve so\u011fumas\u0131n\u0131 kontrol edin. Kaynak i\u015fleminden sonra, levhay\u0131 bir kat ate\u015f battaniyesiyle \u00f6rt\u00fcn; bu, so\u011fuma h\u0131z\u0131n\u0131 azalt\u0131r.<\/p>\n

Baz\u0131 durumlarda, al\u00fcminyum ala\u015f\u0131ml\u0131 kaynakta gerilim \u00e7ok y\u00fcksek olur ve bu da kayna\u011f\u0131n k\u0131r\u0131lganla\u015fmas\u0131na neden olur. Bunu \u00f6nlemek i\u00e7in, i\u00e7 gerilimi ortadan kald\u0131rmak ve kayna\u011f\u0131n mukavemetini art\u0131rmak amac\u0131yla kayna\u011fa \u00e7eki\u00e7le vurmak gerekir.<\/p>\n

4. G\u00f6zenek olu\u015fumu kolayd\u0131r. Kaynakl\u0131 birle\u015fim yerlerindeki g\u00f6zeneklilik, al\u00fcminyum ala\u015f\u0131mlar\u0131n\u0131n kaynaklanmas\u0131 s\u0131ras\u0131nda s\u0131kl\u0131kla ortaya \u00e7\u0131kan bir ba\u015fka kusurdur. Hidrojen, eriyik kayna\u011f\u0131nda g\u00f6zeneklenmenin ana nedenidir. Al\u00fcminyum ala\u015f\u0131m\u0131n\u0131n s\u0131v\u0131 eriyik havuzu gaz\u0131 kolayca emer ve y\u00fcksek s\u0131cakl\u0131kta b\u00fcy\u00fck miktarda gaz \u00e7\u00f6z\u00fcn\u00fcr; kaynak sonras\u0131 so\u011fuma ve kat\u0131la\u015fma s\u00fcrecinde bu gaz\u0131n \u00e7\u00f6kelmesi i\u00e7in art\u0131k \u00e7ok ge\u00e7 oldu\u011fundan, kaynak i\u00e7inde birikerek g\u00f6zenekler olu\u015fturur.
\nKaynak malzemesi ve ana malzeme y\u00fczeyindeki oksit tabakas\u0131n\u0131n emdi\u011fi nem, kaynak gaz\u0131ndaki hidrojenin ana kayna\u011f\u0131d\u0131r. Bu nedenle, kaynak \u00f6ncesinde bu y\u00fczeylerin titizlikle temizlenmesi ve g\u00f6zenek olu\u015fumunu \u00f6nlemek i\u00e7in kaynak i\u015fleminin uygun \u015fekilde se\u00e7ilmesi gerekmektedir.<\/p>\n

5. Renk de\u011fi\u015fimi olmaz. Al\u00fcminyumun rengi \u0131s\u0131t\u0131ld\u0131\u011f\u0131nda de\u011fi\u015fmez. Al\u00fcminyum malzemenin a\u015f\u0131r\u0131 s\u0131cakl\u0131klara maruz kalmas\u0131n\u0131 ve deforme olmas\u0131n\u0131 \u00f6nlemek i\u00e7in \u0131s\u0131tma s\u0131ras\u0131nda bir s\u0131cakl\u0131k g\u00f6stergesi kullan\u0131n. Deformasyonu \u00f6nlemek i\u00e7in a\u015f\u0131r\u0131 \u0131s\u0131nmadan ka\u00e7\u0131n\u0131lmal\u0131d\u0131r. Uzun kaynaklar yap\u0131l\u0131rken b\u00f6l\u00fcmlere ay\u0131rma y\u00f6ntemi kullan\u0131lmal\u0131d\u0131r. Kaynak i\u015flemi a\u015f\u0131r\u0131 \u0131s\u0131nmay\u0131 \u00f6nler.
\nG\u00f6vdedeki al\u00fcminyum ala\u015f\u0131m\u0131n\u0131n kaynaklanmas\u0131nda diren\u00e7li nokta kayna\u011f\u0131 i\u015flemi kullan\u0131lmamaktad\u0131r. Al\u00fcminyumun direnci, demirin direncinin yakla\u015f\u0131k 1\/5\u2019i kadard\u0131r. Uygun diren\u00e7 \u0131s\u0131s\u0131n\u0131 elde etmek i\u00e7in diren\u00e7li nokta kayna\u011f\u0131 kullan\u0131ld\u0131\u011f\u0131nda, kaynak ak\u0131m\u0131 30.000 amper\u2019e ula\u015fmal\u0131d\u0131r. B\u00f6ylesine y\u00fcksek bir ak\u0131ma ula\u015fmak zordur.
\nY\u00fcksek enerji \u00e7\u0131k\u0131\u015f\u0131 gerektirir. \u00dcretim ve onar\u0131m a\u015famalar\u0131nda per\u00e7inleme y\u00f6ntemiyle ikame edilir. Genellikle, onar\u0131m s\u0131ras\u0131nda kaynak i\u015flemleri i\u00e7in al\u00fcminyum inert gaz korumal\u0131 kaynak ekipman\u0131 kullan\u0131l\u0131r.<\/p>","protected":false},"excerpt":{"rendered":"
