01 Yintoni iijoyinti edibeneyo
Ijoyinti edibeneyo ibhekisa kwijoyinti apho izinto ezimbini okanye ngaphezulu zomsebenzi ziqhagamshelwe ngokuhlanganisa. Ijoyinti edibeneyo yokuhlanganisa ijoyinti yenziwe ngokufudumeza kwendawo evela kumthombo wobushushu obuphezulu. Ijoyinti edibeneyo iqulathe indawo yokuhlanganisa (indawo yokuhlanganisa), umgca wokuhlanganisa, indawo echaphazelekileyo kubushushu, kunye nendawo yesinyithi esisiseko, njengoko kubonisiwe kumfanekiso.
02 Yintoni i-butt joint
Isakhiwo sokuwelda esisetyenziswa kakhulu sisixhobo apho iindawo ezimbini ezidityanisiweyo zidityaniswa khona kwindawo enye okanye kwi-arc embindini wesixhobo. Uphawu kukufudumeza okufanayo, amandla afanayo, kwaye kulula ukuqinisekisa umgangatho wokuwelda.
03 Yintoni i-umjelo wokuwelda
Ukuze kuqinisekiswe ukungena kunye nomgangatho wee-welded joints, kunye nokunciphisa ukuguquka kwe-welding, ii-joints zeendawo ezi-welded zihlala zicutshungulwa zibe ziimo ezahlukeneyo ngaphambi kokuba zi-welding. Ii-welding grooves ezahlukeneyo zifanelekile kwiindlela ezahlukeneyo ze-welding kunye nobukhulu be-weldment. Iifom ze-groove eziqhelekileyo ziquka: I-shaped I, i-V, i-U, i-single-shaped V, njl.njl., njengoko kubonisiwe kumfanekiso.

04 Impembelelo yeButt Joint Groove Form kwiUkuwelda kweComposite yeLaser Arc
Njengoko ubukhulu be-welding workpiece bukhula, ukufikelela kwi-single-side welding kunye nokwenziwa kwe-double-side yee-plates eziphakathi nezityebileyo (amandla e-laser <10 kW) kudla ngokuba nzima ngakumbi. Ngokwesiqhelo, kufuneka kusetyenziswe iindlela ezahlukeneyo ze-welding, ezinje ngokuyila iifom ze-groove ezifanelekileyo okanye ukugcina izithuba ezithile ze-docking, ukuze kufezekiswe i-welding yee-plates eziphakathi nezityebileyo. Nangona kunjalo, kwi-welding yokwenyani yemveliso, ukugcina izithuba ze-docking kuya kwandisa ubunzima bezinto zokufakelwa kwe-welding. Ke ngoko, uyilo lwe-groove luba lubalulekileyo ngexesha lenkqubo ye-welding. Ukuba uyilo lwe-groove alunangqiqo, uzinzo kunye nokusebenza kakuhle kwe-welding kuya kuphazamiseka kakhulu, kwaye kwandisa nomngcipheko weziphene ze-welding.
(1) Uhlobo lomsele luchaphazela ngokuthe ngqo umgangatho womsele wokuwelda. Uyilo lomsele olufanelekileyo lunokuqinisekisa ukuba intsimbi yocingo lokuwelda izaliswe ngokupheleleyo kumsele wokuwelda, nto leyo enciphisa ukwenzeka kweziphene zokuwelda.
(2) Imilo yejometri yomngxuma ichaphazela indlela ubushushu obudluliselwa ngayo, nto leyo enokukhokela ngcono ubushushu, ifezekise ukufudumeza nokupholisa okufanayo, kwaye incede ekuphepheni ukuguquka kobushushu kunye noxinzelelo olushiyekileyo.
(3) Imo yomngxuma iya kuchaphazela imo yecandelo elinqamlezileyo lomthungo we-weld, kwaye iya kukhokelela ekubeni imo yecandelo elinqamlezileyo lomthungo we-weld ihambelane ngakumbi neemfuno ezithile, ezinje ngobunzulu nobubanzi bokungena kwe-weld.
(4) Uhlobo olufanelekileyo lomngxuma lunokuphucula uzinzo lokuwelda kwaye lunciphise izinto ezingazinzanga ngexesha lenkqubo yokuwelda, njengokutshiza kunye neziphene ezingaphantsi.
Njengoko kubonisiwe kuMfanekiso 3, abaphandi bafumanise ukuba ukusebenzisa i-laser arc composite welding (amandla e-laser 4kW) kunokugcwalisa umngxuma ngee-layers ezimbini kunye nee-passs ezimbini, nto leyo ephucula ngempumelelo ukusebenza kakuhle kwe-welding; I-welding engenaziphene ye-20mm ubukhulu be-MnDR ifezekisiwe kusetyenziswa i-laser arc composite welding ene-layer arc composite welding ene-layers ezintathu (amandla e-laser angama-6kW); I-laser arc composite welding isetyenziselwe ukuwelda intsimbi ye-low-carbon engama-30mm ubukhulu kwii-layers ezininzi kunye nee-passs, kwaye i-cross-sectional morphology ye-welded joint yayizinzile kwaye ilungile. Ukongeza, abaphandi bafumanise ukuba ububanzi bee-rectangular grooves kunye ne-engile yee-grooves ezimile okwe-Y zinempembelelo enkulu kwisiphumo somda wendawo. Xa ububanzi be-rectangular groove bu≤4mm kwaye i-engile yomjelo omile njengo-Y≤60 °, imo yecandelo elinqamlezileyo lomthungo we-weld ibonisa imifantu ephakathi kunye neenotshi zodonga ezisemacaleni, njengoko kubonisiwe kumfanekiso.

Isishwankathelo se-05
Ukukhethwa kwefom ye-groove kufuneka kuqwalaselwe ngokupheleleyo iimfuno zomsebenzi we-welding, iimpawu zezinto eziphathekayo, kunye neempawu zenkqubo ye-laser arc composite welding. Uyilo olufanelekileyo lwe-groove lunokuphucula ukusebenza kakuhle kwe-welding kwaye lunciphise umngcipheko weziphene ze-welding. Ke ngoko, ukukhethwa kunye noyilo lwefom ye-groove yinto ebalulekileyo ngaphambi kokuba i-laser arc composite welding yeepleyiti eziphakathi nezityebileyo ibe yi-welding.
