Xa i-welding aluminium iityhubhu, umphezulu uhlala ujika ube mnyama. Ndingenza ntoni

I-Porosity ixhaphake kakhulu kwi-welding ye-aluminium.

Kukho umlinganiselo othile we-pores kwizinto ezisisiseko kunye nocingo lwe-welding, ngoko ke kuyimfuneko ukuphepha ama-pores amakhulu ngexesha le-welding ukuqinisekisa ukuba i-pores ayidluli umgangatho. Xa ukufuma kungaphezu kwe-80℅, ukuwelda makuyekwe. Amathuba eepores angaphaya komgangatho nawo angama-80℅, kwaye kulula ukuvelisa iziqwenga ezibuyisiweyo.

I-Welding kwimeko yokufuma eboniswe kumzobo kunokwenzeka kakhulu ukuvelisa umyalelo wokubuya.

Izixhobo zokuwelda iXinfa zineempawu ezikumgangatho ophezulu kunye nexabiso eliphantsi. Ngeenkcukacha, nceda undwendwele:Abavelisi beWelding & Cutting-China Welding & Cutting Factory & Suppliers (xinfatools.com)

Ngamanye amaxesha uthuli olumnyama luya kunamathela kwi-weld, kufuneka ndenze ntoni?

▲Mnyama kunye nengwevu▲

Ngokwenyani, i-electrode ye-tungsten ingcolisekile, okanye ichukumisa idama elinyibilikisiweyo okanye ucingo lwe-welding, kwaye i-aluminiyam incamathele kuyo. Kuphela xa i-electrode ye-tungsten ihlambulukile sinokuqhubeka.

Ngeli xesha, sifuna kuphela ukulungelelanisa ububanzi bokucoca umatshini we-welding ukuya ngasezantsi, okwangoku ngokusisiseko malunga ne-200, kunye ne-arc welding iqaliswe kwisiqwenga se-aluminium esilahliweyo. Kwimizuzwana embalwa nje, i-tungsten electrode iya kwenza ibhola encinci. Ukuba ufuna ukuwelda kakuhle i-aluminium, ibhola encinci yimveliso ekufuneka ube nayo.

Ukuthelekisa ukuwelda kwe-aluminiyam kwintsimbi engatyiwayo, ndikhetha ukuwelda i-aluminiyam. Ayinangxaki njengentsimbi engatyiwayo, ekufuneka ijiwulwe. Ukuwelda kweAluminiyam kulula, kwaye umpu wokuwelda awujingi. Le ityhubhu ye-aluminium ene-liner yi-weld ye-fillet, kwaye i-welding ayikho ingxaki.
Xa ulungelelanisa langoku ngokumodareyitha, eyona yangoku yeyona ikwaziyo ukulawula ichibi elinyibilikisiweyo. Ukusebenza komatshini we-welding ngamnye kuyahluka, okwangoku kuya kuba yinto eyahlukileyo, kwaye ukuguquguquka kwe-arc kuya kwahluka.
