Iziphene eziqhelekileyo kwi-Laser Welding kunye nendlela yokuSombulula

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. Ngezantsi kukho iziphene eziphambili ezifunyenwe kwi-laser welding kunye nendlela yokujongana nazo:

1. Iintanda

Unobangela: Ukuqhekeka kuqhelekile ngenxa yokuncipha okukhulu kwamandla ngaphambi kokuba i-weld pool yomelele ngokupheleleyo. Zihlala zidibaniswa nokuqhekeka okushushu, njengokuqiniswa okanye ukuqhekeka kwe-liquation.

Isisombululo: Ukunciphisa okanye ukuphelisa ukuqhekeka, ukutshisa i-workpiece kunye nokongeza izinto zokuzalisa kunokunceda ukusabalalisa ukushisa 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 we-workpiece ngaphambi kokuba udibanise. 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: Ukunciphisa amandla e-welding kwaye ulungelelanise isantya se-welding ukuya kwinqanaba elifanelekileyo. Oku kuya kunceda ukuthintela ukufunxa okugqithisileyo kwezinto kunye nokunciphisa ukutshiza.

4. Ukutshisa

Unobangela: Esi siphene senzeka xa isantya welding ikhawuleza kakhulu, nto leyo ebangela ulwelo lwesinyithi usilele ukusabalalisa 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: I-undercutting yenzeke xa isantya se-welding sicotha kakhulu, okukhokelela kwi-weld pool enkulu, ebanzi. Ukunyuswa komthamo wesinyithi onyibilikisiweyo kwenza kube nzima ukuxinana komphezulu ukugcina isinyithi elulwelo endaweni, sibangela ukuba sigxumeke.

Isisombululo: Ukunciphisa ubuninzi bamandla kunokuncedisa ukuphepha ukunqumla ngaphantsi, ukuqinisekisa ukuba ichibi elityhidiweyo ligcina imilo kunye namandla kulo lonke inkqubo.

Indima ye IiChillers 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 oonobangela beengcambu eziqhelekileyo ze-laser welding defects kunye nokuphumeza izisombululo ezisebenzayo, ezifana nokufudumeza, ukulungelelanisa amandla kunye nezicwangciso zesantya, kunye nokusebenzisa i-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.
