Amaqembu imbobo

Ngesikhathi sokuqothulwa, umphumela wokuvikela we-arc kanye ne-sla uba buthakathaka futhi kulula ukuba yi-porosity ejwayeleke kanye nezinye iziphambeko ku-crater.Izinga lokukhubazeka lingasuswa lapho ithrekhi elandelayo yokushisela amalunga, ukuqeda imiphumela yokuhle noma emibi kuncike ekuhlanganyeleni lapho kuncibilika, ukuncibilika ngangokunokwenzeka, kuqeda ngokuphelele amaphutha anjalo.Izindawo zokushisa ze-boiler esiteshini samandla ngokuvamile ziyi-calandria disorder, ukuphazamiseka ngendlela yesinqumo esihlangene kakhulu emgwaqweni lapho amalunga e-crater ye-weld yesikhathi esifushane sokusebenza, kunzima ukunqoba iziphambeko, kungaholela kalula ekukhishweni. ipayipi ashiselwe amalunga avele Amaqembu izimbobo

Hlikihla izimbobo

Lapho ukushiselwa kwe-arc kagesi okwenziwa ngesandla kuthinta i-angle yokutsheka yomphumela wokuvikela we-weld enkulu, uma kungenjalo kunqubo yokushisela njalo igcina i-engeli elungile, nakanjani izobangela ukungena kwamagesi ayingozi ngaphandle, ngaphandle kokwanda kobude bomthungo obulungile be-engeli, izokwakha. i-strip vent.Lapho izinga lepayipi elikhulu lobubanzi ligxilile kuwo wonke amakhanda we-welding welding, ngenxa yokuphakama ukuze i-welder kufanele ithathe izikhundla ze-welding zihlukile ezindaweni ezahlukene ukuze kugcinwe ukusebenza kwe-angle bar.Ku-oblique oblique flat welding kanye nezikhundla zokushisela ngaphezulu, i-welder in posture nzima kakhudlwana, kunzima ukugcina ama-engeli amabha afanele athunyelwa, ngakho ukushisela lezi zindawo zivame ukuhlubula izimbobo.Iphutha elincane lokushisela ipayipi le-diameter kwenzeka ikakhulukazi ngenxa yokwakhiwa kweshalofu akulungile.Ukuhamba ngesivinini kanye nokushintshashintsha kunquma ukushuba kobuhlalu obubodwa, isivinini esithunyelwa ngokushesha senza ama-electrode adinge ukushintsha ngokushesha i-engeli, noma angakwazi ukwakha i-slag ephumelelayo = ukuvikelwa okuhlangene kwegesi.Ngemuva kokufakwa kwezidingo zokushisela amashubhu amancane, ikhava izacile, ukushisela ngesandla kufanele kugcine isivinini sokuthutha esisheshayo, kuzoba nezimbobo zokuhlubula.

Ukungena okungaphelele

Amajoyinti ashiselwe amashubhu e-Fin avame ukucabanga ngendlela efanayo, kanye nokuwohloka kokuncipha kwe-welding, okuholela ekubeni kube nzima kakhulu ukugcina okuhambisanayo okufanelekile, lapho ukusekelwa kokushisela kwe-melting degree bevel kuba buthaka, okuholela ekuntulekeni kokungena.Insimbi engagqwali Welding okudlekayo oluncibilikisiwe ukugeleza metal impofu, futhi ukushisa ngokushesha, ukushisa akulula ukugxilisa ingqondo, okuholele ekushiseni kwe-arc nokuncibilika kwesisekelo sensimbi noma insimbi yokushisela kunzima ukugcwalisa, ukwakheka kokukhubazeka kokungena okungaphelele. .Ngokuvamile ipayipi elikhulu eliwugqinsi eliwugqinsi, amalunga lapho i-welding isekela uma kungenjalo ukungena kwezimpande, kubangelwa ukungabi khona kokungena;ububanzi obukhulu obunama-tube onqenqema olubi bukhulu, kungenzeka bubangele ukungena okungaphelele.

I-Slag

Lapho i-soldering, ubukhulu bensimbi yokugcwalisa buzothinta ukuchichima kwe-slag esintantayo, ukukhubazeka kwe-slag akukwazi ukugcwala ngokuphelele uma i-slag yakhiwe.Ipayipi lokushisela ipayipi eliwugqinsi eliwugqinsi ngokuvamile lisetshenziswa lapho umsinga omkhulu, ubukhulu be-single-pass welding slag obuntantayo bunzima kakhulu ukwenza amaphutha e-slag.I-Liquidity filler metal slag inethonya elikhulu ekukhiqizeni amaphutha.Insimbi engagqwali yensimbi encibilikisiwe yokuhamba kahle, kuhlanganiswe nokusetshenziswa kwe-weld encane yamanje ewumngcingo, ukuqina kwensimbi ye-weld, okunzima ukugcwalisa i-weld slag, ukwakheka kwe-slag kokukhubazeka.I-welding enezingqimba, i-soldering oblique welding head ithatha umzila, inombolo yomzila njengoba isingathwe kabi, ingabangela i-weld "efile", ibe nethuba elikhulu lokukhubazeka kwe-slag.

Ukuqhekeka

I-TIG ishaya phansi njengencane, ukucindezeleka kuzokwenza ukuthi kwenzeke lapho ugcwalisa izinyembezi ezibangelwa ukwakheka kwemifantu;hhayi ngesikhathi esifanele i-sub-layer esekela i-weld ngemuva kwe-welding, kodwa futhi imbangela yokuqhekeka.Ukushisa kwangaphambi kokushisa kanye nokugcinwa kwenduku ye-welding engafanele, ukusetshenziswa okungalungile, kuzokwandisa ithuba lokuqhekeka.
