Ukuqhuba kunye ne-Keyhole Laser Welding

Ukuqonda iTechnique yeWelding eqhelekileyo

I-laser welding inokwahlulwa ibe ziindidi ezimbini eziphambili: i-welding conduction kunye ne-keyhole welding.

Ezi nkqubo zimbini ziyahluka kwindlela i-laser edibana ngayo nezinto kunye neziphumo abazivelisayo.

Iiyantlukwano eziphambili

Umgangatho Welding

I-welding ye-Conduction ivelisa iziphumo ezicocekileyo kunye ne-spatter encinci kunye neziphene ezimbalwa, ngelixa i-keyhole welding inokubangela isiphala, i-porosity, kunye nendawo enkulu echatshazelwe bubushushu.

Ukusasazwa kobushushu beWelding

I-welding ye-Conduction isasaza ubushushu ngokulinganayo kuzo zonke iinkalo, ngelixa i-keyhole ye-welding igxininise ubushushu kwindawo encinci, i-perpendicular direction, ekhokelela ekungeneni okunzulu.

Isantya seWelding

I-Keyhole welding ikhawuleza, iyenza ilungele ukuveliswa kwevolumu ephezulu, ngelixa i-welding conduction ihamba kancinci kodwa inika ngokuchanekileyo ngakumbi.

Ukuqhuba ukuWelding

Ukwenziwa kwewelding yinkqubo ethambileyo necothayo. Kule ndlela, umqadi we-laser unyibilika umphezulu wesinyithi.

Ukubangela ukuba isinyithi sifikelele kwiqondo lokushisa lokudibanisa (indawo apho ijika ibe lulwelo).

Kodwa ungagqibi ngaphaya koko ukuya kubushushu bomphunga (apho isinyithi siya kujika sibe yigesi).

Ubushushu busasazwa ngokulinganayo kuyo yonke into, oku kuthetha ukuba ukuhanjiswa kobushushu kwenzeka kuzo zonke iinkalo ngaphakathi kwesinyithi.

Ngenxa yokuba i-welding conduction inyibilika kancinci kancinci, ivelisa iziphumo ezikumgangatho ophezulu.

Oku kubandakanya i-spatter encinci (amathontsi amancinci ezinto ezityhidiweyo ezinokubaleka ngexesha le-welding) kunye nomsi ophantsi, okwenza inkqubo icoceke.

Nangona kunjalo, ngenxa yokuba iyacotha, i-welding conduction iqhele ukusetyenziselwa izicelo ezifuna ukuchaneka kunye nomgangatho ophezulu wamalungu kunesantya.

Keyhole Welding

I-Keyhole welding, ngakolunye uhlangothi, yinkqubo ekhawulezayo kunye nobudlova.

Kule ndlela, i-laser beam iyanyibilika kwaye ikhuphe isinyithi, idala umngxuma omncinci, onzulu okanye isitshixo kwizinto eziphathekayo.

Ubushushu obukhulu belaser bubangela ukuba isinyithi sifikelele kuzo zombini ubushushu bomxube kunye nobushushu bomoya.

Ngenxalenye yedama elinyibilikisiweyo elijika libe yigesi.

Ngenxa yokuba izinto zenziwe ngumphunga, ubushushu bugqithiselwa ngakumbi kwi-perpendicular kwi-laser beam, okukhokelela kwi-weld pool enzulu, encinci.

Le nkqubo ikhawuleza kakhulu kunokuba i-welding conduction, iyenze ilungele imigca yemveliso ephezulu.

Nangona kunjalo, ubushushu obukhawulezayo kunye nobushushu obunamandla bunokubangela i-spatter, kwaye ukunyibilika ngokukhawuleza kunokukhokelela kwi-porosity (amaqamza amancinci avaleleke ngaphakathi kwi-weld).

Kunye nendawo enkulu echatshazelwe bubushushu (HAZ) (indawo ejikeleze i-weld eguqulwa bubushushu).
