Zobuchwepheshe argon Welding

Isethi kwemikhiqizo esetshenziswa ekhaya umkhakha, abenziwe insimbi kanye Alloys yabo. Ukuze okuhlala kanye eliphezulu uxhumano unomphela imikhiqizo metal indlela engcono - the Welding Fusion. Phakathi izindlela, kancane futhi ivumela ukuthola izinga ezinhle weld, Welding argon kungenziwa okuthiwa. Lona uhlobo Welding arc. Lisisebenzisa arc evutha phakathi non-consumable (ngokuvamile - tungsten) electrode kanye workpiece metal. I electrode is shelwe sikaphalafini nangaphandle yanikezwa zone ukuncibilika filler impahla akuyona ingxenye wesifunda kagesi. Emaphethelweni metal isizinda kanye material yamathebhu Incibilikile ngu-plasma arc futhi yakha umphetho. Ukushisela pool ngokusebenzisa umlomo wombhobho sikaphalafini kwimodi okuzenzakalelayo ayenamanzi igesi engaxubani namakhemikhali kuyinto argon. It cishe Asingeni nokuxhumana chemical ne metal oncibilikisiwe kanye amagesi kwakheka indawo arc. Ngenxa yokuthi i-Ari kuyinto 38% ngoyisiwula kusinda kunakho emoyeni, yehla, displacing yamagesi asemkhathini kusukela zone weld, ngaleyo ndlela ukuvikela ke nokuvimbela okuvela yokulimala joint ashiselwe. Ukuze wehlise porosity weld, kungase ukungezwa argon ka 3-5% oksijini, ke Ukuvikelwa metal iyasebenza.

Argon Welding ihlinzeka kumiswa weld ngu inki jet noma ukudlulisa metal globular. ukudluliselwa Globular kubangela ukuhlakazwa ebanzi futhi awukwazi sifinyelele inqubo Welding esimeme. izici kwezobuchwepheshe etholakale lapho la umphetho bonke kubo mubi kunothango e Welding semiautomatic e CO _2. ukudluliselwa metal Inkjet inikeza argon Welding at Welding imisinga phezu zokuxhumana mina = 260A. Kule nqubo the Welding kuba esitebeleni weld izinga kuyathuthuka. Kodwa isicelo esinjalo amperage okusezingeni eliphezulu ngokuvamile oluhambisana nezidingo zobuchwepheshe yenqubo (isib ngokungafanele heats workpiece futhi sishintsha izakhiwo izinsimbi elixutshiwe). Ngakho-ke uyelulekwa ukusebenzisa ukushintsha segezi. Lokhu kuvumela ukushintsha jet lokudluliselwa metal kakade imisinga zokuxhumana eduze mina = 100A.

ukuthungela uma usebenzisa electrode non-consumable eyalo idivayisi ekhethekile - i oscillator exhunywe parallel umthombo wamandla. Lapho Welding argon wenziwa ku kushintshana zamanje, ngemva ukuthungela we arc esitshalweni imodi oscillator isimame, ukusuthisa phakathi pulses arc ngokushintsha polarity. Lokhu kuqinisekisa ukuzinza arc.

Uma isicelo wamanje njalo, lo cathode futhi anode kwenzeka engalingani ukushisa ukukhululwa (angaba ngu-70% - ngesikhathi anode). Ngakho-ke, lezinsimbi, titanium Alloys nezinye izinsimbi kuka-aluminiyamu, wasebenzisa polarity ngqo ukukhulisa preform is bhotela. Al Welding wenziwa ngezinga elingakaze zamanje kushintshana, okuvumela ukuba abhubhise ifilimu oxide, ngaphandle okweqile umkhiqizo.

Ukuze Welding izingxenye eyenziwe lezinsimbi engagqwali, aluminium futhi Alloys yayo ingaphinda isetshenziswe argon-arc Welding nge electrode consumable. Nokho, nobukhulu bayo itsatfwa iyincane kunokuhlala tungsten electrode.

Isetshenziselwa kokubili manual kanye othomathikhi argon Welding. Phakathi zako zihlanganisa ikhono ukukhiqiza kwakwakhe imikhiqizo of ukushuba encane ngaphandle weld yamathebhu izinto, umsebenzi ngendlela ukufinyelela kwamanzi. Indlela muhle kakhulu Welding Butt yokuma amapayipi metal. Ezakhiwe weld unamapharamitha ezinhle zobuchwepheshe. Argon arc Welding - ubuchwepheshe, zezakhi ofanele kakhulu lezinsimbi elixutshiwe, titanium Alloys, aluminium.

Ngenxa lula eyisihlobo indlela, argon Welding izandla siqu akutholakali kuphela welders okhokhelwayo. Kulokhu, ngenxa lemali elincane umsebenzi, hhayi umkhiqizo kubaluleke kangaka eliphansi inqubo, okwenza zilinganiselwe izinhlobo elisetshenziswa ukukhiqizwa emikhulu.
