Iingxaki kunye neZisombululo eziNxulumene neNkqubo yeWelding yeePlati eziThick and Thin
1. Yintoni ekufuneka yenziwe ukuba ubukhulu bomsebenzi wentsimbi budlula ubuninzi be-welding yangoku umatshini wokuwelda unokufikelela xa usebenzisa i-gas metal arc welding (GMAW) kunye ne-flux cored wire gas arc welding (FCAW) ukuwelda i-workpieces yentsimbi?
Isisombululo kukufudumala isinyithi ngaphambi kwe-welding. Ukushisa ummandla we-welding we-workpiece usebenzisa i-propane, i-gas standard okanye i-acetylene welding torch, kunye nokushisa kwangaphambili kwe-150-260 ℃, kwaye emva koko uqhubeke ne-welding. Injongo yokufudumeza isinyithi kwindawo ye-welding kukukhusela indawo ye-weld ekupholiseni ngokukhawuleza, ukwenzela ukuba kungabangela ukuqhekeka okanye ukudibanisa okungaphelelanga kwi-weld.
2. Ukuba kuyimfuneko ukusebenzisa i-electrode enyibilikayo yegesi ekhuselekileyo ye-welding okanye i-flux cored wire gas shielded welding ukuwelda isigqubuthelo sentsimbi esibhityileyo kumbhobho wentsimbi otyebileyo, ukuba i-welding yangoku ayikwazi ukulungiswa ngokuchanekileyo ngexesha le-welding, kunokukhokelela kwiimeko ezimbini:
Enye kukunciphisa i-welding yangoku ukukhusela isinyithi esincinci ukuba singatshi, kwaye ngeli xesha, isigqubuthelo sentsimbi esincinci asikwazi ukudityaniswa kumbhobho wentsimbi; Okwesibini, i-welding yangoku ngokugqithisileyo inokutshisa ngee-caps zetsimbi ezincinci. Ifanele isingathwe njani le nto?
Kukho ikakhulu izisombululo ezibini:
① Lungisa i-welding yangoku ukunqanda ukutshisa kwisigqubuthelo sesinyithi esicekethekileyo, fudumeza umbhobho oshinyeneyo wentsimbi ngetotshi yokuwelda, emva koko usebenzise itekhnoloji yokuwelda ipleyiti ebhityileyo ukuwelda izakhiwo ezibini zentsimbi.
② Lungisa i-welding yangoku ukuze ilungele ukuwelda imibhobho yentsimbi eshinyeneyo. Xa udibanisa, gcina ixesha lokuhlala kwi-arc ye-welding kumbhobho wensimbi obunzima kwi-90% kwaye unciphise ixesha lokuhlala kwikhava yensimbi encinci. Kufuneka kucaciswe ukuba kuphela xa ubuchule bobu buchule bunokuthi kufumaneke ama-welding joints.
- Xa udibanisa umbhobho obhityileyo wesetyhula okanye uxande obhityileyo onodonga ukuya kwipleyiti eshinyeneyo, intonga ye-welding ithanda ukutshisa ngenxalenye yombhobho obhityileyo. Ngaphandle kwezi zisombululo zimbini zingasentla, ngaba zikho ezinye izisombululo?
Ewe, ikakhulu usebenzisa intonga yokuphelisa ubushushu ngexesha lenkqubo ye-welding. Ukuba intonga eyomeleleyo engqukuva ifakwe kumbhobho obhityileyo ojikelezayo, okanye intonga eyomeleleyo yoxande ifakwe kumbhobho woxande wokulinganisa, intonga eyomeleleyo iya kubususa ubushushu bomsebenzi obhityileyo obhityileyo kwaye ithintele ukuvutha. Ngokubanzi, iirodi ezizingqukuva eziqinileyo okanye ezixande zifakwe ngokuqinileyo kuninzi lwemathiriyeli engumgongxo ekhoyo okanye engumbhobho wexande. Xa i-welding, ingqalelo kufuneka ihlawulwe ekugcineni i-weld kude nokuphela kombhobho, eyona ndawo isengozini kakhulu yokutshisa. Umzobo weskim wokusebenzisa isinki sobushushu esakhelwe ngaphakathi ukunqanda ukutshisa uboniswe kuMfanekiso 1.
- Ingaba igalvanized okanye ichromium equlathe imathiriyeli idityaniswa njani kwenye indawo?
Eyona ndlela yenkqubo kukufayila okanye ukupolisha indawo ejikeleze i-weld phambi kwe-welding, njengoko i-galvanized okanye i-chromium equlethe iipleyiti zetsimbi zingangcolisi nje kwaye zenze buthathaka i-weld, kodwa zikhupha iigesi ezinetyhefu ngexesha le-welding.
