5 Laser Welding Quality Problems & Solutions

Iingxaki ze-5 ze-Laser Welding Quality & Solutions

Hlangana nemeko eyahlukileyo ye-laser welder

Ngobuchule obuphezulu, ukuchaneka okuphezulu, isiphumo esikhulu sokuwelda, ukudityaniswa okuzenzekelayo okuzenzekelayo, kunye nezinye iingenelo, i-laser welding isetyenziswa ngokubanzi kumashishini ahlukeneyo kwaye idlala indima ebalulekileyo kwimveliso yentsimbi yokuwelda kunye nemveliso, kubandakanywa emkhosini, unyango, i-aerospace, i-3C. iinxalenye zemoto, intsimbi yentsimbi, amandla amatsha, izixhobo zococeko, kunye namanye amashishini.

Nangona kunjalo, nayiphi na indlela ye-welding ukuba ayiphumelelanga umgaqo wayo kunye neteknoloji, iya kuvelisa iziphene ezithile okanye iimveliso ezineziphene, i-laser welding ayifani. Kuphela ukuqonda kakuhle kwezi ziphene, nokufunda indlela yokuphepha ezi ziphene, ukudlala ngcono ixabiso welding laser, processing inkangeleko entle, kunye neemveliso ezisemgangathweni. Iinjineli ngokuqokelela amava exesha elide, zishwankathela ezinye iziphene zokuwelda ezixhaphakileyo zesisombululo, kwireferensi yabalingane boshishino!

1.Iintanda

Iintanda eziveliswe kwi-laser ye-welding eqhubekayo ziyi-cracks eshushu kakhulu, njengeentanda ze-crystallization, i-liquefied cracks, njl. Ukusebenzisa i-wire feeder ukuzalisa iingcingo okanye ukufudumeza isiqwenga sentsimbi kunokunciphisa okanye kuphelise iintanda ezibonisiweyo ngexesha le-laser welding.

2.Pores kwi weld

I-Porosity sisiphene esilula kwi-laser welding. Rhoqo i-laser welding pool inzulu kwaye imxinwa, kwaye iintsimbi zihlala ziqhuba ubushushu kakuhle kwaye zikhawuleza kakhulu. Irhasi eveliswe kwidama elinyibilikisiweyo lolwelo ayinaxesha laneleyo lokubaleka phambi kokuba intsimbi yokuwelda iphole phantsi. Ityala elinjalo lilula ukukhokelela ekubunjweni kwama-pores. Kodwa kwakhona ngenxa yokuba indawo yobushushu belaser incinci, isinyithi sinokuphola ngokukhawuleza, i-porosity eboniswe kwi-laser welding incinci kune-welding yendabuko ye-fusion. Ukucoca umphezulu we-workpiece phambi kwe-welding kunokunciphisa ukuthambekela kwee-pores, kwaye ulwalathiso lokuvuthela luya kuchaphazela ukubunjwa kwee-pores.

3.Ukuchaphaza

Ukuba weld workpiece yentsimbi ngokukhawuleza kakhulu, intsimbi engamanzi emva komngxuma eyalathe embindini we weld ayinaxesha lokusasaza kwakhona. Ukuqinisa kumacala omabini e-weld kuya kwenza i-bite. Xa umsantsa phakathi kwamaqhekeza amabini omsebenzi umkhulu kakhulu, kuya kubakho ukungonelanga kwesinyithi esinyibilikisiweyo esifumanekayo kwi-caulking, kwimeko apho ukuluma komphetho we-welding kuya kwenzeka. Kwinqanaba lokugqibela le-laser welding, ukuba amandla awela ngokukhawuleza, umngxuma kulula ukuwa kwaye ubangele iziphene ezifanayo ze-welding. Amandla angcono okulinganisa kunye nesantya esishukumayo soseto lwe-laser welding inokusombulula ukuveliswa kokuluma komphetho.

4.Undercut

I-splash eveliswa yi-laser welding ichaphazela kakhulu umgangatho we-weld surface kwaye inokungcolisa kwaye yonakalise ilens. I-spatter inxulumene ngokuthe ngqo nobuninzi bamandla, kwaye inokuncitshiswa ngokunciphisa ngokufanelekileyo amandla e-welding. Ukuba ukungena akwanelanga, isantya se-welding sinokuncitshiswa.

5.Ukudilika kwedama elityhidiweyo

Ukuba isantya welding uyacotha, ichibi otyhidiweyo likhulu kwaye banzi, isixa esinyibilikisiweyo iyanda, kunye noxinzelelo umphezulu kunzima ukugcina ulwelo enzima metal, iziko weld uya kutshona, ukwenza ukudilika kunye nemingxuma. Ngeli xesha, kuyimfuneko ukunciphisa ubuninzi bamandla ngokufanelekileyo ukuze ugweme ukuwa kwechibi elinyibilikisiweyo.
