Phakathi nenqubo yokushisela, abashiseli bangabona ungqimba lwempahla yokumboza entanta phezu kwechibi elincibilikisiwe, elivame ukubizwa ngokuthi i-welding slag. Indlela yokuhlukanisa i-welding slag kusuka ensimbi encibilikisiwe kubaluleke kakhulu kwabaqalayo. Ngicabanga ukuthi kufanele kuhlukaniswe ngale ndlela.
Okokuqala, i-slag ye-welding ingumkhiqizo wokuncibilika kwe-electrode coating kanye ne-high-temperature metallurgical reaction of the weld. I-slag yokushisela yakhiwa ikakhulukazi ama-oxide ensimbi noma ama-non-metal oxides namanye ama-salts amaminerali. Njengoba ukuminyana kwayo kukuncane kakhulu kunokwensimbi ewuketshezi ngesikhathi sokushisela, umshiseli angakwazi ukubona kalula ungqimba lwezinto ezintantayo engxenyeni engenhla yechibi elincibilikisiwe phakathi nenqubo yokushisela. Ngokombala, imnyama kunensimbi ewuketshezi echibini elincibilikisiwe, futhi igeleza ibheke kolunye uhlangothi lwendlela yokushisela futhi nhlangothi zombili zangemuva, futhi iphole njengoba ukushisela kuqhubeka nokuba i-slag yokushisela.
Imishini yokushisela i-Xinfa inezici zekhwalithi ephezulu nenani eliphansi. Ukuze uthole imininingwane, sicela uvakashele:Abakhiqizi Bezinto Zokushisela Nezokusika - Imboni Yokushisela Nokusika YaseChina Nabahlinzeki (xinfatools.com)
Okwesibili, i-welding slag idlala indima enkulu ekuvikeleni ubuhlalu be-weld ngesikhathi senqubo yokushisela. I-slag ivala insimbi ewuketshezi echibini elincibilikisiwe ukuze ihlukanise insimbi ewuketshezi emoyeni, ivimbele ukungena kwamagesi ayingozi njengomoya-mpilo, i-nitrogen, ne-hydrogen emoyeni, ngaleyo ndlela ivikele ubuhlalu obushiselayo. Ngakho-ke, ngesikhathi senqubo yokushisela, kufanele unake i-angle yokushisela ukuze uqinisekise ukuthi i-slag yokushisela igeleza ngemuva nasezinhlangothini zombili zomhlane, ukuze ubone ukwakheka kwe-weld, ugweme isizukulwane sokukhubazeka njenge-slag. inclusions kanye nama-pores, futhi uqinisekise izinga lokushisela. Okwesithathu, ngokusho komshini wokushisela onolwazi esizeni, uma ufuna ukuhlonza insimbi encibilikisiwe ngesikhathi sokushisela, udinga kuphela ukubheka ngokucophelela futhi uzothola ukuthi i-slag yokushisela entanta phezu kwensimbi ewuketshezi ifana namafutha emanzini, antanta phezu kwensimbi. ichibi elincibilikisiwe, okulula kakhulu ukulibona.
