Indlela yokusebenza yeArgon arc welding
I-Argon arc ngumsebenzi apho izandla ezisekhohlo kunye nezokunene zihamba ngexesha elifanayo, okufana nokudweba izangqa ngesandla sasekhohlo kunye nokudweba izikwere ngesandla sokunene ebomini bethu bemihla ngemihla. Ngoko ke, kucetyiswa ukuba abo baye baqala ukufunda i-argon arc welding babe noqeqesho olufanayo, oluya kuba luncedo ukufunda i-argon arc welding.
(1) Ukutya ngeengcingo: zahlulwe zaba kukuzaliswa kocingo lwangaphakathi kunye nokuzaliswa kocingo lwangaphandle.
I-filler yangaphandle yocingo ingasetyenziselwa i-priming kunye nokuzaliswa. Isebenzisa umsinga omkhulu. Intloko yocingo lwe-welding ingaphambili kwi-groove. Isandla sasekhohlo sicudisa ucingo lwe welding kwaye ngokuqhubekayo siyithumela kwidama elinyibilikisiweyo lokuwelda. I-gap ye-groove ifuna i-gap encinci okanye ayikho.
Iinzuzo zayo kukusebenza okuphezulu kwemveliso kunye nezakhono zokusebenza lula ngenxa ye-gap enkulu yangoku kunye nencinci. Ukungalungi kwayo kukuba ukuba isetyenziselwa ukuhla, ngenxa yokuba umqhubi akakwazi ukubona ukunyibilika komphetho onqabileyo kunye nokuqiniswa kwecala elingasemva, kulula ukuvelisa ukungaxutywanga kwaye ungafumani ukubunjwa kwe-reverse efanelekileyo.
Ucingo lokuzalisa lwangaphakathi lungasetyenziselwa kuphela ukuxhasa i-welding. Sebenzisa ubhontsi, umnwe wesalathisi okanye umnwe ophakathi wesandla sakho sasekhohlo ukulungelelanisa isenzo sokutyisa ucingo. Umnwe omncinci kunye nomsesane ubambe intambo ye-welding ukulawula indlela. I-wire welding isondele kumda onqabileyo ngaphakathi kwi-groove kwaye iyancibilika kunye ne-edge edge ye-welding, i-gap ye-groove iyadingeka ukuba ibe nkulu kunobubanzi bocingo lwe-welding. Ukuba iplate, ucingo lwe-welding lunokugotywa kwi-arc.
Inzuzo yalo kukuba ngenxa yokuba ucingo lwe-welding lukwelinye icala le-groove, umgca onqabileyo kunye nemeko yokunyibilika kocingo lwe-welding ibonakala ngokucacileyo, kwaye ukuqiniswa kwe-reverse kunokubonwa kumbono we-peripheral wamehlo. i-weld fusion ilungile, kwaye ukomeleza umva kunye nokungadibanisi kunokufunyanwa ulawulo olulungileyo. Ukungalungi kukuba umsebenzi unzima, kwaye i-welder iyadingeka ukuba ibe nezakhono zokusebenza ezinobuchule. Ngenxa yokuba i-gap inkulu, umthamo we-welding uya kwanda ngokufanelekileyo. I-gap inkulu, ngoko ke i-current iphantsi, kwaye ukusebenza kakuhle komsebenzi kuhamba kancinci kunocingo lokuzalisa lwangaphandle.
(2) Izibambo ze-welding zohlulwe zibe ziziphatho ze-crank kunye ne-mops.
Isiphatho sokungcangcazela kukucinezela umbhobho wokuwelda kancinci kumthungo we-welding, kwaye ushukumise ingalo kakhulu ukuwelda. Izibonelelo zayo kukuba i-welding nozzle icinezelwe kwi-weld seam, kwaye isibambo se-welding sizinzile kakhulu ngexesha lokusebenza, ngoko ke umthungo we-weld ukhuselwe kakuhle, umgangatho ulungile, imbonakalo buhle kakhulu, kwaye izinga lokufaneleka kwemveliso liphezulu. . Ifumana umbala obukekayo omhle kakhulu. Ukungalungi kukuba kunzima ukufunda, kuba ingalo iyagubha kakhulu, ngoko ke akunakwenzeka ukuba udibanise kwimiqobo.
I-mop ithetha ukuba incam yewelding ingqiyame kancinci kuyo okanye ayingqiyanga kumthungo we-weld, umnwe omncinci okanye umnwe weringi wesandla sasekunene ukwayama okanye awungqiyanga kwisixhobo sokusebenza, ingalo ijinga kancinci, kwaye irhuqa isibambo se-welding. yewelding. Inzuzo yayo kukuba kulula ukuyifunda kwaye ikwazi ukuguquguquka. Ukungalungi kwayo kukuba imilo kunye nomgangatho awushukunyiswa kakuhle, ngakumbi kwi-welding ephezulu ngaphandle kwe-shaker ukwenza lula ukuwelda. Kunzima ukufumana umbala ofanelekileyo kunye nokumila xa welding steel stainless.
(3) I-arc ignition: I-arc ignition isetyenziswa ngokuqhelekileyo (i-oscillator ephezulu-frequency okanye i-high-frequency pulse generator), kunye ne-electrode ye-tungsten kunye ne-weldment ayidibanisi ukuvutha i-arc. Xa kungekho arc ignition, i-contact arc ignition isetyenziswa (isetyenziswa kakhulu kwiindawo zokwakha) ufakelo, ngokukodwa ukufakwa komgangatho ophezulu), ubhedu okanye igraphite inokubekwa kwi-groove ye-weldment ukubetha i-arc, kodwa le ndlela ingaphezulu. inzima kwaye isetyenziswa kancinci. Ngokuqhelekileyo, i-stroke ekhanyayo kunye ne-welding wire yenza ukuba i-weldment kunye ne-tungsten electrode ibe mfutshane kwaye ikhutshwe ngokukhawuleza. Kwaye ulayite i-arc.
(4) I-Welding: Emva kokuba i-arc ivutha, kuyimfuneko ukutshisa i-3-5 imizuzwana ekuqaleni kwe-weldment, kwaye uqale ukutyisa ucingo emva kokuba i-pool etyhidiweyo yenziwe. Xa udibanisa, i-angle ye-welding wire torch kufuneka ifaneleke, kwaye ucingo lwe-welding kufuneka lutyiswe ngokulinganayo. Itotshi yokuwelda kufuneka iqhubele phambili kakuhle, ijiwuze ngasekhohlo nasekunene icothe kancinane kumacala omabini, kwaye ikhawuleze kancinci embindini. Nika ingqalelo kakhulu utshintsho lwedama elityhidiweyo. Xa ichibi elityhidiweyo liba likhulu, i-weld seam iba banzi, okanye i-welding seam iba concave, isantya se-welding kufuneka sandiswe okanye i-welding current iyancipha kwakhona. Xa i-fusion ye-pool etyhidiweyo ayilungile kwaye ucingo alukwazi ukutyiswa, kuyimfuneko ukunciphisa isantya se-welding okanye ukwandisa i-welding current. Ukuba i-welding ephantsi, amehlo kufuneka agxininise kumaphethelo amnyama kumacala omabini e-groove, kunye neekona zamehlo. Ukukhanya kwe-peripheral kukwelinye icala le-slit, kwaye ubeke ingqalelo ekutshintsheni kwezinye iindawo eziphakamileyo.
I-5) Ukucima i-arc: Ukuba i-arc icinyiwe ngokuthe ngqo, kulula ukuvelisa i-shrinkage cavity. Ukuba itotshi ye-welding ine-arc starter, i-arc kufuneka ivalwe ngamaxesha athile okanye ilungelelaniswe kwi-arc crater current efanelekileyo. I-arc ikhokelwa kwelinye icala le-groove, kwaye akukho mngxuma wokunciphisa owenziweyo. Ukuba umngxuma wokushwabana uyenzeka, kufuneka uphuculwe phambi kokuba udityaniswe.
Ukuba i-arc ikwi-joint, i-joint kufuneka ifakwe kwi-bevel kuqala, kwaye i-welded phambili kwi-10-20mm emva kokuba i-joint inyibilike ngokupheleleyo, kwaye i-arc ivalwe ngokukhawuleza, kwaye akukho mgodi wokucutha ungenzeka. Kwimveliso, kudla ngokubonakala ukuba amajoyina awaphuculwanga kwii-bevels, kwaye ixesha lokuthungatha kwamalungu linwetshiwe ngokuthe ngqo kumalungu. Lo ngumkhwa ombi kakhulu. Ngale ndlela, amajoyina axhomekeke kwi-concave, amalunga angaxutywanga kwaye i-reverse side iphuma kwi-joint, eya kuchaphazela ukubonakala kobume. Ukuba i-alloy ephezulu Izinto eziphathekayo nazo zixhomekeke kwiintanda.
