Isifinyezo sezindlela ezahlukene zokushisela

I-Welding iyisidingo esiyisisekelo ezimbonini eziningi. Ukuhlanganisa kanye nokushintsha izinsimbi zibe yizimo nemikhiqizo kudinga ochwepheshe abanekhono abafunde umsebenzi wabo wezandla kusukela kofunda umsebenzi ukuya empeshenini kusukela ekuqaleni. Ukunaka imininingwane kwenza i-welder enkulu, futhi ukushisela okuhle kwaziswa kakhulu ezitolo eziningi zokwenziwa. Njengoba i-automation iqhubeka nokukhukhula kwezohwebo abanamakhono, ukushisela kuhlala kuyikhono elingakwazi ukwenziwa ngamarobhothi ngokugcwele, futhi abashiseli abafundile bahlale bedingeka.

I-Stick Welding/Arc Welding (SMAW)

I-Stick welding yaziwa nangokuthi i-shielded metal arc welding (SMAW). Kule ndlela yokushisela, i-welder isebenzisa induku yokushisela enqubweni ye-manual, isebenzisa amandla kagesi ukuze idale i-arc phakathi kwenduku nezinsimbi okumele zihlanganiswe. Le ndlela ivame ukusetshenziswa ekwakhiweni kwezakhiwo zensimbi nasekwakhiweni kwezimboni ukushisela insimbi. Umshiseli osebenzisa le ndlela kufanele abe nekhono elanele ukuze adlulise insimbi yokushisela ngokuhlolwa kokugoba okulimazayo. Le ndlela ilula ukuyifunda, kodwa idinga ijika lokufunda elide ukuze ube umpetha. I-Stick welding nayo ayidali isiphetho esihle kakhulu, ngakho-ke igcinelwa ama-welds angabonakali emkhiqizweni oqediwe. Le ndlela ilungele ukulungiswa kwemishini ngoba isebenza ezindaweni ezigqwalile, ezipendiwe nezingcolile.

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

I-Gas Metal Arc Welding (GMAW) yaziwa nangokuthi i-MIG (Metal Inert Gas) yokushisela. Le ndlela yokushisela isebenzisa igesi evikelayo eduze kwama-electrode bese ishisa izinsimbi ezimbili ezizohlanganiswa. Le ndlela idinga i-voltage engaguquki evela kumthombo wamandla we-DC futhi iyinqubo yokushisela yezimboni esetshenziswa kakhulu. Le ndlela ilungele ukushisela insimbi yeshidi eliwugqinsi libe yindawo evundlile.

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

I-gas tungsten shielded welding (GTAW), eyaziwa nangokuthi i-TIG (tungsten inert gas) welding, isetshenziselwa ngokuyinhloko ukuhlanganisa izingxenye eziwugqinsi zensimbi engagqwali noma izinsimbi ezingenayo ayoni. Lena enye inqubo yokushisela i-arc eshisela nge-electrode ye-tungsten engaguquki, kodwa inqubo idla isikhathi esiningi kunenduku noma i-MIG yokushisela. Ukwakhiwa kwesisekelo sensimbi kubaluleke kakhulu uma usebenzisa le ndlela, njengoba iphesenti le-chromium lithinta izinga lokushisa elincibilikayo. Lolu hlobo lwe-welding lungenziwa ngaphandle kwe-filler metal. Ngenxa yokugeleza kwegesi okuqhubekayo okudingekayo, le ndlela yenziwa kangcono ekamelweni elikude nezakhi. Ukushisela kwe-TIG kukhiqiza amashisela amahle, kodwa kunzima ukukwazi futhi kudinga umuntu onolwazi futhi onekhono.

I-Flux cored arc welding

I-Flux cored arc welding (FCAW) yathuthukiswa njengenye indlela yokushisela okuvikelekile. Le ndlela iyashesha futhi iyaphatheka, futhi iyindlela esetshenziswa kakhulu emisebenzini yokwakha. Isetshenziswa kumaphrojekthi we-welding ahlukahlukene futhi inikeza ukuguquguquka okukhulu kwe-engeli, i-voltage, i-polarity nesivinini. Lolu hlobo lwe-welding lwenziwa kangcono ngaphandle noma ngaphansi kwe-fume hood njengoba ludala umusi omningi phakathi nenqubo.

Kungakhathaliseki ukuthi hlobo luni lokushisela olusetshenziselwa iphrojekthi yakho yokwenziwa kwensimbi ngokwezifiso, kubalulekile ukuba nomuntu onekhono oqonda ubunkimbinkimbi bendlela ngayinye kanye nezinsimbi asebenza ngazo. Isitolo sokwenziwa kwensimbi yesakhiwo esisezingeni sizoba nethimba eliqinile labashiseli abazidlayo ngomsebenzi wabo wezandla futhi bangancoma uhlobo olungcono kakhulu lokushisela kuphrojekthi ngayinye.
