Ulawulo lobushushu obuchanekileyo kwiiNkqubo zeLaser kunye nezicelo zoShishino ukusukela ngo-2002
Ulwimi
Iziphene ze-laser welding ezifana nokuqhekeka, i-porosity, i-spatter, ukutshisa, kunye ne-undercutting zingabangela ukusetwa okungafanelekanga okanye ulawulo lobushushu. Izisombululo ziquka ukulungelelanisa iiparamitha ze-welding kunye nokusebenzisa ii-chillers ukugcina ubushushu obuhambelanayo. Izitshizi zamanzi zinceda ukunciphisa iziphene, ukukhusela izixhobo, kunye nokuphucula umgangatho wokuwelda kunye nokuqina.
I-laser welding yindlela esebenza kakhulu kwaye ichanekile esetyenziswa kumashishini ahlukeneyo. Nangona kunjalo, iziphene ezithile ezifana nokuqhekeka, i-porosity, i-spatter, i-burn-through, kunye ne-undercutting ingenzeka ngexesha lenkqubo. Ukuqonda izizathu zezi ziphene kunye nezisombululo zabo zingundoqo ekuphuculeni umgangatho we-welding kunye nokuqinisekisa iziphumo ezihlala ixesha elide. Apha ngezantsi kukho iziphene eziphambili ezifunyenwe kwi-laser welding kunye nendlela yokujongana nazo:
1. Iintanda
Unobangela: Ukuqhekeka kuqhelekile ngenxa yokuncipha okukhulu kwamandla phambi kokuba i-weld pool yomelele ngokupheleleyo. Zihlala zidibaniswa nokuqhekeka okushushu, njengokuqiniswa okanye ukuqhekeka kwe-liquation.
Isisombululo: Ukunciphisa okanye ukuphelisa iintanda, ukutshisa i-workpiece kunye nokongeza izinto zokuzalisa kunokunceda ukusabalalisa ubushushu ngokulinganayo, ngaloo ndlela kuncitshiswe uxinzelelo kunye nokuthintela ukuqhekeka.
2. I-Porosity
Unobangela: I-laser welding yenza i-weld pool enzulu, emxinwa kunye nokupholisa ngokukhawuleza. Iigesi eziveliswa echibini elityhidiweyo azinalo ixesha elaneleyo lokubaleka, okukhokelela ekubunjweni kweepokotho zegesi (i-pores) kwi-weld.
Isisombululo: Ukunciphisa i-porosity, coca umphezulu weworkpiece ngocoselelo phambi kokuba welding. Ukongeza, ukulungelelanisa indlela yegesi ekhuselayo kunokuncedisa ukulawula ukuhamba kwegesi kunye nokunciphisa amathuba okubunjwa kwepore.
3. I-Spatter
Unobangela: I-Spatter inxulumene ngokuthe ngqo noxinaniso lwamandla. Xa uxinaniso lwamandla luphezulu kakhulu, i-material iba ngumphunga kakhulu, ibangela ukuba i-spplashes yezinto ezityhidiweyo zibhabha ziphume kwi-weld pool.
Isisombululo: Nciphisa amandla e-welding kwaye ulungelelanise isantya se-welding ukuya kwinqanaba elifanelekileyo. Oku kuya kunceda ukuthintela ukufunxa okugqithisileyo kwezinto kunye nokunciphisa ukutshiza.
4. Ukutshiswa
Isizathu: Esi siphene senzeke xa isantya se-welding sikhawuleza kakhulu, sibangela ukuba isinyithi esilulwelo singaphumeleli ukusabalalisa kwakhona ngokufanelekileyo. Ingenzeka kwakhona xa umsantsa odibeneyo ubanzi kakhulu, unciphisa ubungakanani besinyithi esinyibilikisiweyo esifumanekayo sokudibanisa.
Isisombululo: Ngokulawula amandla kunye nesantya se-welding ngokuvumelana, ukutshisa-ngendlela kunokuthintelwa, ukuqinisekisa ukuba i-weld pool ilawulwa ngokufanelekileyo kwi-bonding efanelekileyo.
5. Ukusika ngaphantsi
Unobangela: Ukusika ngaphantsi kwenzeka xa isantya sokuwelda sicotha kakhulu, okukhokelela kwichibi elikhulu, elibanzi. Ukunyuswa komthamo wesinyithi onyibilikisiweyo kwenza kube nzima ukuxinana komphezulu ukugcina isinyithi elulwelo endaweni, sibangela ukuba sigxumeke.
Isisombululo: Ukunciphisa ubuninzi bamandla kunokunceda ukuphepha ukunqumla ngaphantsi, ukuqinisekisa ukuba ichibi elityhidiweyo ligcina imilo kunye namandla kulo lonke inkqubo.
Indima yeeChillers zaManzi kwi-Laser Welding
Ukongeza kwezi zisombululo zingasentla, ukugcina ubushushu obuphezulu bokusebenza kwe-laser welder kubalulekile ekuthinteleni ezi ziphene. Apha kulapho i-water chillers idlala khona. Ukusebenzisa i-chiller yamanzi ngexesha lenkqubo ye-laser welding kubalulekile kuba inceda ukugcina ubushushu obuhambelanayo kwi-laser kunye ne-workpieces. Ngokulawula ngokufanelekileyo ubushushu kwindawo ye-welding, i-chillers yamanzi inciphisa indawo echaphazelekayo yokushisa kwaye ikhusele amacandelo abonakalayo obuthathaka kumonakalo wokushisa. Oku kuqinisekisa ukuzinza kunye nomgangatho we-laser beam, ekugqibeleni kuphuculwe umgangatho we-welding kunye nokunciphisa amathuba okuba neziphene ezifana nokuqhekeka kunye ne-porosity. Ngaphaya koko, ii-chillers zamanzi zandisa ubomi besixhobo sakho ngokuthintela ukutshisa kakhulu kunye nokubonelela ngokuthembekileyo, ukusebenza okuzinzileyo.
Ukuqukumbela: Ngokuqonda izizathu ezisisiseko ze-laser welding defects eziqhelekileyo kunye nokuphumeza izisombululo ezisebenzayo, ezifana nokufudumeza, ukulungelelanisa amandla kunye nesantya, kunye nokusebenzisa ii-chillers, unokuphucula kakhulu umgangatho we-welding. La manyathelo aqinisekisa umgangatho ophakamileyo, ubuhle, kunye neemveliso ezihlala ixesha elide, ngelixa uphucula ukusebenza ngokubanzi kunye nobomi besixhobo sakho sokuwelda i-laser.
Ngolwazi oluthe kratya malunga nendlela yokuphucula inkqubo yakho ye-laser welding kunye nezisombululo zokupholisa ezikumgangatho ophezulu, zive ukhululekile ukuqhagamshelana nathi.
