Intshayelelo
Kwimizi-mveliso, iiwelder zamandla ezigciniweyo zisetyenziswa kakhulu ekudibaniseni isinyithi ngenxa yokusebenza kakuhle kwazo kunye{0}}neempawu zokonga amandla. Nangona kunjalo, umgangatho we-welding uchaphazela ngokuthe ngqo ukusebenza kwemveliso kunye nokhuseleko, okwenza ukuba ukuhlolwa kwe-weld kubaluleke kakhulu. Eli nqaku lihlalutya ngokucwangcisiweyo iindlela zokuhlola i-weld yeewelda zamandla agciniweyo, ukusuka{3}}okungonakalisiyo ukuya kuvavanyo olonakalisayo, ukukunceda uvavanye ngokwenzululwazi umgangatho we-welding.
I. UHlolo oluBonakalayo: Esona siGqibo siSiseko esiSiseko
Ukuhlolwa okubonakalayo linyathelo lokuqala ekuhlolweni kwe-weldiiwelders zamandla ezigciniweyo. Ngokujonga ngokubonakalayo ukuba i-weld surface igudile, ayinazo iintanda, iipores, okanye i-inclusions, umgangatho we-welding unokugwetywa kwangaphambili. Umzekelo, ukuba umbala we-weld awulingani okanye unoxinzelelo olucacileyo, unokubonisa ukungonelanga kwamandla okanye uxinzelelo olungaqhelekanga lwe-electrode. Le ndlela ilula ukuyisebenzisa kodwa ilungele kuphela ukukhangela isiphene somphezulu kwaye ayikwazi ukuchonga imiba yangaphakathi.
II. -Uvavanyo olungonakalisiyo: Ukuchonga ngokuchanekileyo iziphene zangaPhakathi
- X-Uvavanyo lweray
Ngokwembono weld amanqaku ngaphakathi X-reyi, iziphene ezifana neentanda, iipores, okanye ukungabikho fusion inokubonwa. Ngexesha lokuvavanya, i-weld ibekwe phakathi kwe-X{2}}yemvelaphi kunye ne-detector, kwaye inkqubo yokucubungula imifanekiso yenza imifanekiso ecacileyo yesakhiwo sangaphakathi. Le ndlela ifanele iimeko eziphezulu-ezichanekileyo (ezifana ne-automotive body welding) kodwa ineendleko eziphezulu zezixhobo.
- Uvavanyo lwe-ultrasonic
Isebenzisa i-propagation and reflection features of ultrasound in welds ukubona iziphene zangaphakathi. Ngokuhlalutya ukuqina kunye nexesha lemiqondiso ebonakalisiweyo, inokugqiba ukuba i-weld ine-voids okanye i-bonding ebuthakathaka. Le ndlela ayifuni ukuqhagamshelana ne-workpiece kwaye ifanelekile ukuvavanya i-batch, kodwa idinga izakhono eziphezulu zobugcisa kubaqhubi.
- Screwdriver Gap Test
Faka intsimbi yentsimbi okanye isikrudrayiva phakathi kweentsimbi ezimbini ezidityanisiweyo, usebenzisa uxinzelelo ukuze wenze umsantsa oyi-2.5 -3.5 mm. Ukuba i-weld iyinto eqhelekileyo, iintsimbi azikwazi ukuchithwa; ukuba bahlukana ngokulula, kubonisa ukungonelanga kokuqina kwe-welding. Le ndlela ilula kwaye iyasebenza, ifanelekile ukuba ihlolwe ngokukhawuleza kwisayithi.
III. Uvavanyo olonakalisayo: Ukuqinisekisa iiPropati zeWeld Mechanical
- Iinyembezi / Jika uvavanyo
Jonga ngokuthe ngqo ukuqina kwe-weld ngokuyikrazula okanye ukuyijija ngesandla. Ukuba i-weld iphula kunye nomphezulu ogudileyo kwaye akukho zintanda ezicacileyo, umgangatho we-welding ulungile. Nangona le ndlela intuitive, iyonakalisa i-workpiece kwaye ifanelekile kwiibhetshi ezincinci okanye ukuqinisekiswa kwesigaba se-R & D.
- Uvavanyo lwe-Tensile
Faka amandla e-tensile kwi-weld kumatshini wokuvavanya imathiriyeli yendalo yonke de waphuke. Vavanya iipropati zomatshini we-weld ngokurekhoda idatha efana namandla okuqina kunye nobude. Le ndlela ibonelela ngeziphumo ezichanekileyo kodwa ineendleko eziphezulu, ezisetyenziswa ngokuqhelekileyo kumashishini anemigangatho engqongqo yomgangatho.
IV. Uvavanyo loBulukhuni: Ukuvavanya amandla ezinto eziphathekayo kunye nokuqina
Sebenzisa abavavanyi bobulukhuni be-Rockwell okanye iBrinell ukulinganisa ubulukhuni be-weld, ebonisa ngokungangqalanga amandla kunye nokuqina kwayo. Amaxabiso obunzima obuphezulu okanye obuphantsi angabonisa iiparamitha ze-welding ezingaqhelekanga (ezifana nokungonelanga kwamandla okanye uxinzelelo olugqithisileyo lwe-electrode). Le ndlela ifanelekile kulawulo lomgangatho we-welding yentsimbi engafaniyo (efana ne-aluminium kunye nobhedu).
Ukuqukumbela
Ukuhlolwa kwe-weldiiwelders zamandla ezigciniweyokufuna ukukhetha iindlela ezifanelekileyo ezisekelwe kwiimfuno zenkqubo kunye neempawu zezixhobo. Ukusuka ekuhlolweni okubonwayo ukuya kubuchwephesha obuphambili obufana ne-X-reyi kunye ne-ultrasound, kwaye emva koko ukuya kungqinisiso olonakalisayo olufana novavanyo oluqinileyo, indlela nganye inoncedo. Ngovavanyo lwezenzululwazi, ayisiyiyo kuphela iziphene ze-welding, kodwa iiparamitha zezixhobo zinokwandiswa ukuphucula impumelelo yemveliso kunye nokuthembeka kwemveliso. Kumashishini alandela{4}}imveliso ekumgangatho ophezulu, ukwazi ezi ndlela zokuvavanya linyathelo eliphambili ekuqinisekiseni umgangatho wokuwelda.
