Uma ushisela amashubhu e-aluminium, ingaphezulu lihlala liba mnyama. Kumele ngenzeni

I-porosity ivame kakhulu ekushiseleni i-aluminium.

Kukhona inani elithile lama-pores ku-base material kanye nocingo lwe-welding, ngakho-ke kuyadingeka ukugwema ama-pores amakhulu ngesikhathi sokushisa ukuze uqinisekise ukuthi ama-pores awadluli izinga. Uma umswakama ungaphezu kuka-80℅, ukushisela kufanele kumiswe. Amathuba ezimbotshana adlula izinga nawo angama-80℅, futhi kulula ukukhiqiza izingcezu ezibuyisiwe.

I-Welding esimweni somswakama esiboniswe emfanekisweni kungenzeka kakhulu ukukhiqiza umyalelo wokubuyisela.

Imishini yokushisela i-Xinfa inezici zekhwalithi ephezulu nenani eliphansi. Ukuze uthole imininingwane, sicela uvakashele:Abakhiqizi Bezinto Zokushisela Nabasika - Imboni Yokushisela & Cutting yase-China & Suppliers (xinfatools.com)

Ngezinye izikhathi uthuli olumnyama luzonamathela ku-weld, yini okufanele ngiyenze?

Empeleni, i-electrode ye-tungsten ingcolile, noma ithinta ichibi elincibilikisiwe noma intambo yokushisela, bese i-aluminium inamathela kuyo. Kuphela lapho i-electrode ye-tungsten ihlanzwa singaqhubeka.

Ngalesi sikhathi, sidinga kuphela ukulungisa ububanzi bokuhlanza bomshini wokushisela phansi, okwamanje okwamanje cishe ku-200, futhi ukushisela kwe-arc kuqalwa ocezwini lwe-aluminium elahlekile. Ngemizuzwana embalwa nje, i-electrode ye-tungsten izokwakha ibhola elincane. Uma ufuna ukushisela i-aluminium kahle, ibhola elincane liwumkhiqizo okufanele ube nawo.

Ukuqhathanisa ukushisela kwe-aluminium nensimbi engagqwali, ngikhetha ukushisela i-aluminium. Ayinankinga njengensimbi engagqwali, edinga ukushwitshwa. Ukushisela i-aluminium kulula, futhi isibhamu sokushisela empeleni asijiki. Le tube ye-aluminium ene-liner iyi-weld ye-fillet, futhi ukushisela akuyona inkinga.
Lapho ulungisa yamanje ngokusesilinganisweni, yamanje engcono kakhulu yileyo ekwazi ukulawula ichibi elincibilikisiwe. Ukusebenza komshini wokushisela ngamunye kuhlukile, okwamanje kuzoba okuhlukile, futhi ukuguquguquka kwe-arc kuzophinde kuhluke.
