Ungazikhetha njani iirobhothi ze-Laser Welding
Yintoni iRobotic Laser Welding kunye noMgaqo wayo wokuSebenza?
Ukuwelda kweLaser Roboticidibanisa umthombo wokukhanya we-laser ogxilileyo kunye neerobhothi zamashishini ezicwangcisiweyo okanye iirobhothi ezisebenzisanayo. Ithatha indawo yokusebenza ngesandla ngesandla kunye neentshukumo ezizinzileyo kunye nezilawulekayo zoomatshini ukufezekisa inqanaba eliphezulu lokuphindaphinda kwiinkqubo ze-welding.
Amandla -aphezulu{1}}umqa welaser oxinanisayo agxininiswe ngokuchanekileyo kwindibaniselwano yezinto zokusebenza, enyibilika ngoko nangoko isinyithi ngokwendawo ukwenza idama elinyibilikisiweyo elincinane. Iqhutywa yirobhothi, intloko ye-laser ihamba ngesantya esingaguqukiyo. Intsimbi etyhidiweyo isasazeka ngokuqhubekayo kwaye emva koko iphole ngokukhawuleza kwaye yomelele, yenze i-weld ene-metallurgical bonding exineneyo.
Iimpawu eziphambili: I-laser ihambisa amandla agxininiswe kakhulu ngogalelo lobushushu obuphantsi kakhulu kunye nobushushu obumxinwa-INdawo eChaphazelekileyo (HAZ), ekhokelela kutshintsho lwewelding oluncinci lwezixhobo zokusebenza. Ifanelekile ukuwelda iipleyiti ezincinci, iindawo ezichanekileyo kunye neentsimbi ezingafaniyo.

Izinto eziluncedo kwiRobotic Laser Welding
Ultra-ephezulu ePhindayo ukuChaneka kokubekwa
Ukuphindaphinda ukuchaneka kokumisa kwe-robot ye-6-axis industrial ifikelela kwi-0.02 ~ 0.05 mm. Ukuveliswa kobuninzi bamawaka ee-workpieces, indawo ye-weld, ubunzulu bokungena kunye nokwakheka kwe-weld kuhlala kuhambelana ngokupheleleyo, ukuphelisa iimpazamo zokusebenza kwezandla kunye nokunciphisa kakhulu amaxabiso okusebenza kwakhona.
Uguqulo oluPhantsi kunye noMgangatho woMphezulu oPhezulu
Ngegalelo lobushushu obuphantsi, iipleyiti ezincinci azibonisi i-warpage ecacileyo emva kwe-welding. I-welds incinci kwaye igudileyo, ivumela inkqubo yokugaya ukuba ishiywe okanye ibe lula kakhulu, enciphisa kakhulu izinga lokulungisa.
Kuphuculwe kakhulu ukusebenza ngokuFanelekileyo
Kwi-welds yobude obufanayo, isantya se-welding ye-laser ye-robotic welding welding yi-3 ukuya ku-8 amaxesha e-TIG kunye namaxesha ama-2 ukuya kuma-5 e-MIG.
