Isishwankathelo seendlela ezahlukeneyo ze-welding

Ukuwelda kuyimfuno esisiseko kumashishini amaninzi.Ukudibanisa kunye nokuguqula iintsimbi zibe yimilo kunye neemveliso kufuna iingcali ezinezakhono ezifunde ubugcisa bazo ukusuka kwi-apprentice ukuya kwi-master kwasekuqaleni.Ukuthathela ingqalelo kwiinkcukacha kwenza i-welder enkulu, kwaye ukuwelda okukhulu kuxabiswa kakhulu kwiivenkile ezininzi zokwenziwa.Njengoko i-automation iqhubeka nokukhukula kurhwebo lwezakhono, i-welding ihlala isisakhono esingenakwenziwa ngokupheleleyo, kwaye iiwelders ezifundileyo zihlala zifunwa.

I-Stick Welding/Arc Welding (SMAW)

Ukuwelda intonga kwaziwa ngokuba yi-shielded metal arc welding (SMAW).Kule ndlela ye-welding, i-welder isebenzisa intonga ye-welding kwi-manual process, isebenzisa umbane wombane ukwenza i-arc phakathi kwentonga kunye neentsimbi eziza kudibaniswa.Le ndlela isetyenziswa ngokuqhelekileyo ekwakhiweni kwezakhiwo zetsimbi kunye nemveliso yokuvelisa i-weld steel.Umshicileli osebenzisa le ndlela kufuneka abe nezakhono ngokwaneleyo ukudlula isinyithi se-weld ngokusebenzisa uvavanyo lwe-bend elonakalisayo.Le ndlela ilula ngokufanelekileyo ukuyifunda, kodwa ifuna ixesha elide lokufunda ukuze ube yinkosi.I-welding yentonga nayo ayidali esona siphelo sibukekayo, ngoko ke igcinelwe iiwelds ezingabonakali kwimveliso egqityiweyo.Le ndlela ilungile kulungiso lwezixhobo kuba isebenza kwindawo erulileyo, epeyintiweyo nemdaka.

I-Metal inert gas (MIG) welding okanye i-GMAW

IGas Metal Arc Welding (GMAW) ikwabizwa ngokuba yiMIG (Metal Inert Gas) welding.Le ndlela yokuwelda isebenzisa irhasi ekhuselayo ecaleni kwee-electrode kwaye emva koko ifudumeza iintsimbi ezimbini eziza kudityaniswa.Le ndlela ifuna i-voltage eqhubekayo evela kumthombo wamandla we-DC kwaye yeyona nkqubo isetyenziswa kakhulu kwimizi-mveliso.Le ndlela ilungele ukuwelda icwecwe elishinyeneyo libe kwindawo ethe tye.

I-Tungsten Inert Gas (TIG) Welding (GTAW)

I-gas tungsten shielded welding (GTAW), ekwaziwa ngokuba yi-TIG (igesi ye-tungsten enert) iwelda, isetyenziselwa ukuwelda kunye amacandelo ashinyeneyo entsimbi engenakutyiwa okanye iintsimbi ezingenayo i-ferrous.Le yenye inkqubo ye-arc welding edibanisa i-electrode ye-tungsten eguquguqukayo, kodwa inkqubo idla ixesha elide kunentonga okanye i-MIG welding.Ukubunjwa kwesiseko sesinyithi kubaluleke kakhulu xa usebenzisa le ndlela, njengoko ipesenti yechromium ichaphazela ukushisa okunyibilikayo.Olu hlobo lwe-welding lunokwenziwa ngaphandle kwesinyithi sokuzalisa.Ngenxa yokuhamba rhoqo kwegesi efunekayo, le ndlela ibhetele eyenziwa kwigumbi elikude nezinto.I-TIG welding ivelisa iiweld ezintle, kodwa kunzima ukuyiqonda kwaye ifuna umntu onamava kunye nezakhono.

I-Flux cored arc welding

I-Flux cored arc welding (FCAW) yaphuhliswa njengenye indlela ye-welding ekhuselweyo.Le ndlela iyakhawuleza kwaye iyaphatheka, kwaye yeyona ndlela isetyenziswa kakhulu kwiiprojekthi zokwakha.Isetyenziswa kwiiprojekthi ezahlukeneyo ze-welding kwaye ibonelela ngokuguquguquka okukhulu kwi-engile, i-voltage, i-polarity kunye nesantya.Olu hlobo lwe-welding lwenziwa kakuhle ngaphandle okanye phantsi kwe-fume hood njengoko idala i-fumes eninzi ngexesha lenkqubo.

Nokuba loluphi na uhlobo lokuwelda olusetyenziselwa iprojekthi yakho yokwenziwa kwentsimbi yesiko, kubalulekile ukuba nomntu onobuchule bokuwelda obuqondayo ubucukubhede bendlela nganye kunye neentsimbi abasebenza ngazo.Ivenkile esemgangathweni yokwakhiwa kwentsimbi iya kuba neqela eliqinileyo labashicileli abazingcayo ngomsebenzi wabo kwaye banokuncoma uhlobo olungcono lwe-weld kwiprojekthi nganye.
