Izakhono ze-pien

Imibhobho ye-Galvanited yizinto eziqhelekileyo zokwakha, zisetyenziswa ngokubanzi ngokwakhiwa, iibhulorho, imibhobho yamanzi kunye namanye amasimi. Kwizicelo ezisebenzayo, i-welding yemibhobho ye-ithakane ibaluleke kakhulu, ke iyimfuneko kwizakhono ezifanelekileyo ukuze kuqinisekiswe umgangatho wokhuseleko kunye nokhuseleko. Nazi ezinye iingcebiso zokuya kumbhobho we-welvan

1. Unyango lomphezulu luyafuneka ngaphambi kokuba welding. Kuba umphezulu wombhobho we-gavaniwe udibene nongqimba lwe-zinc, unyango lomphezulu luyafuneka ngaphambi kokuba uvele ukususa ukungcola ezinje nge-zinc yomaleko we-zinc kunye ne-oyile kumphezulu. Izixhobo ezinje ngevili lokugaya okanye iibrashi zingasetyenziselwa unyango olungaphezulu ukuqinisekisa umgangatho kunye nokuqina kwe-shul.

2. Khetha into efanelekileyo yokwenyama kunye nendlela ye-welding. Izinto ze-welding ze-wilvaning paipes zinokuba yi-wireding wire okanye i-rod ye-rod, njl njl. Ngokwendlela ye-welding, i-arc ye-arc yelding, igesi ekhuselweyo kwaye ezinye iindlela zinokukhethwa. Indlela ethile ye-welding kufuneka ikhethwe ngokweyona meko kunye neemfuno ze-welding.

3. Lawula ubushushu be-welding kunye nexesha. Xa i-welding yemibhobho ye-Wilvaning, kuyimfuneko ukulawula ubushushu be-welding kunye nexesha ukuthintela ukugqithisa okanye ukugqithiswa kwe-welding, okuya kuchaphazela umgangatho wokhuseleko kunye nokhuseleko. Ngokubanzi, ubushushu be-welding kufuneka bulawulwe phakathi kwe-220 ° C kunye ne-240 ° C, kwaye ixesha le-welding kufuneka lilawulwe ngokufanelekileyo ngokwezixhobo ze-welding kunye neendlela.

4. Nika ingqalelo ukukhusela iindawo ze-welding. Xa i-Welvaning Pepes, inkathalo kufuneka ithathelwe ukukhusela iindawo ezinamaphandle ukuthintela i-oxidation egqithisileyo kunye nokususwa kwamalungu edlelo. Izixhobo ezinje ngearhente yokhuselo okanye iteyiphu yokukhusela inokusetyenziselwa ukhuseleko ukuqinisekisa umgangatho kunye nokuqina kwenxalenye yelungu le-weldadi.

5. Yenza itsheki yomgangatho kunye novavanyo. Emva kokuba i-welding igqityiwe, uhlolo olusemgangathweni kunye novavanyo luyafuneka ukuqinisekisa umgangatho kunye nokhuseleko lwe-welding. Iindlela zokuhlola ezinje nge-ultrasonic, i-ray okanye i-magnetic isetyenziselwa ukuhlolwa komgangatho wokuqinisekisa ukuba umgangatho we-welding hlangabezana neemfuno.
