Kangangeminyaka engaphezu kwekhulu, ukuwelda kube yenye yezona ziseko zokwenziwa kwemizi-mveliso. Ukususela ekwakhiweni kweenqanawa nakwimveliso yeemoto ukuya kubunjineli beenqwelo-moya kunye nokwenziwa kwentsimbi engagqwaliyo, ishishini lanamhlanje lixhomekeke kwimithungo yokuwelda eqinileyo nethembekileyo.

Kodwa kukho ingxaki efihlakeleyo iifektri ezininzi ezisayithatha lula:

I-weld ilungile kuphela xa umphezulu wayo ucocekile.

Emva kokuwelda, iileya ze-oxide, umbala wobushushu, i-slag, i-oyile residue, ungcoliseko lomsi, kunye neempawu zokutsha zihlala zijikeleze umthungo wokuwelda. Ezi zinto zingcolisayo azichaphazeli nje kuphela inkangeleko - zichaphazela ngokuthe ngqo ukumelana nokugqwala, ukunamathela kwengubo, ukuthembeka kwesakhiwo, kunye nobomi bemveliso.

Iindlela zokucoca zemveli ezifana nokugaya, ukucola ngamakhemikhali, ukuxubha ngentambo, kunye nokuqhumisa isanti ziyasokola ngakumbi ukuhlangabezana nemigangatho yokuvelisa yanamhlanje.

Yiyo loo ntooomatshini bokucoca nge-laserngokukhawuleza ziba yenye yezona teknoloji zibalulekileyo ekulungisweni komthungo we-weld kwimizi-mveliso.

Kutheni ukuCoca umthungo we-Weld kubalulekile ngakumbi kunangaphambili?

Ukuveliswa kwanamhlanje kuguqukela ku:

• Ukuchaneka okuphezulu
• Ulawulo lomgangatho oluqinileyo
• Ubuhle obungcono
• Impembelelo ephantsi kokusingqongileyo
• Imveliso ezenzekelayo

Kule meko, ungcoliseko lomthungo we-weld luba yingxaki enkulu kwimizi-mveliso.

Emva kokuwelda, iziphene eziqhelekileyo ziquka:

• Umbala wobushushu
• Ii-oxides ezimnyama
• Iintsalela ze-slag
• Ukutshintsha kombala womphezulu
• Ungcoliseko lwekhabhoni
• I-Spatter
• Iindawo zokuqala umhlwa

Uphando lubonisa ukuba ezi mveliso zinganciphisa ukumelana nokugqwala kwaye zichaphazele kakubi ukusebenza kokugquma.

Ngokukodwa kwi-stainless steel welding, ukutshintsha kombala we-oxide ejikeleze indawo ye-weld kunokutshabalalisa umaleko wokukhusela i-chromium oxide, okwandisa umngcipheko wokugqwala.

Yingakho amashishini afana nala:

• Izixhobo zokutya
• Ukuveliswa kwezonyango
• Iimoto
• Inqwelo-moya
• Amandla
• Ukwenziwa ngokuchanekileyo

ngoku jonga ukucocwa kwe-weld njengenkqubo ebalulekileyo yemveliso endaweni yokuba yinyathelo lobuhle.

Ingxaki yokucoca nge-Weld yendabuko

Kangangamashumi eminyaka, iifektri bezixhomekeke kwezi zinto zilandelayo:

• Amavili okusila
• Intlama yokuqhola
• Ukuqhumisa okurhabaxa
• Ukupolisha ngesandla
• Ukucoca i-asidi yekhemikhali

Ezi ndlela zisekho, kodwa zibangela iingxaki ezikhulayo.

Ukucoca Ukugaya Nokurhawuzelela

Ukusila kususa izinto ezingcolisayo ngenkani.

Ingxaki?
Ikwasusa nenxalenye yesinyithi esisisiseko.

Oku kunoku:

• Ukugqitywa komphezulu womonakalo
• Ubukhulu obutshintshileyo
• Nciphisa indawo yokuwelda

Ukucocwa nge-laser kuhambelana ngokugqibeleleyo naloo mfuno.

Indlela Oomatshini Bokucoca NgeLaser Abacoca Ngayo IiWeld Seams

Umatshini wokucoca nge-laser usebenzisa umqadi we-laser wefayibha exineneyo ukususa ungcoliseko kwindawo yokuwelda.

Le nkqubo iyasebenza kuba izinto ezingcolisayo zifunxa amandla e-laser ngokwahlukileyo kwi-substrate yesinyithi.

Njengoko i-laser iskena kwi-weld seam:

• IiOxides ziyaba ngumphunga
• Umbala wobushushu uyanyamalala
• Ukususwa kweentsalela zomphezulu
• Isinyithi esisisiseko asichaphazeleki kangako

Ngokungafaniyo nokusila okanye ukuqhumisa:

• Akukho kuthintana ngokomzimba okwenzekayo
• Akukho khemikhali zifunekayo
• Akukho zixhobo zokurhawuzelela ezisetyenziswayo

Oku kuvumela ulawulo oluchanekileyo kakhulu lokucoca.

Uphando malunga nokususwa kwe-laser oxide luqinisekisa ukuba iinkqubo ze-laser zinokususa i-weld oxidation ngelixa zigcina ukuthembeka kwezinto kunye nobuhle bazo.

Inzuzo yokwenyani yemizi-mveliso: Ukuchaneka ngaphandle komonakalo

Eyona nto ibangela ukuba iifektri zisebenzise ukucoca nge-laser weld akusiyo isantya sodwa.

Kukulawula.

Iindlela zokucoca zemveli ziyatshabalalisa ngokwemvelo.

Ukucoca nge-laser kuyakhetha.

Loo mahluko utshintsha uqoqosho lwemveliso yanamhlanje.

Ukucoca nge-laser kungenza oku kulandelayo:

• Gcina ijiyometri ye-weld
• Khusela amaphepha esinyithi abhityileyo
• Gcina umphezulu ugqityiwe
• Kuphephe ungcoliseko lwesibini
• Phucula ukuphindaphindeka

Iingcali ezininzi zokuwelda eziqala ngokuvavanya ukucoca nge-laser ziyamangaliswa yindlela elawulwa ngayo le nkqubo xa ithelekiswa nokusila okanye ukuqhumisa. Abanye abasebenzisi baxela ukuba isinyithi esisisiseko sihlala singaguquki kwaye sibukhali nasemva kokususwa kwe-oxidation.

Kwimizi-mveliso apho inkangeleko ibaluleke khona — ingakumbi ukwenziwa kwentsimbi engagqwaliyo — oku kuchaneka kuba luncedo kakhulu.

Kutheni ukuCoca ngeLaser kuphucula umgangatho weWeld

Ishishini lokuwelda liqala ukuqonda into ebalulekileyo:

Ukucoca akwahlukanga kumgangatho wokuwelda.

Yinxalenye yomgangatho wokuwelda.

Ungcoliseko lomphezulu ngaphambi okanye emva kokuwelda lunokubangela:

• Ukugquma
• Ukudibana okubuthathaka
• Izinto ezibandakanyiweyo
