Kwiminyaka yakutshanje, uphuhliso lweshishini lokuvelisa luye lwakhawuleza kakhulu, kwaye imfuno yokulungiswa kwesinyithi iye yanda.I-Welding yenye yeenkqubo ezibalulekileyo zokulungisa isinyithi, kwaye iindlela zemveli ze-welding azikwazanga ukuhlangabezana neemfuno zemveliso.Ngaphantsi kwesi sizathu, iumatshini welding laser weldingyazalwa, eyanconywa ngokubanzi xa iqalisiwe, kwaye yatshintsha ngokukhawuleza imarike yemveli yokuwelda ipleyiti ebhityileyo.
Iumatshini wokuwelda ifayibha laser ngesandlasisizukulwana esitsha sezixhobo zokuwelda i-laser.Yeyokuwelda okungaqhagamshelwanga nayo.Ayifuni uxinzelelo ngexesha lokusebenza., enyibilikisa i-material ngaphakathi, kwaye emva koko ipholile kwaye ikhazimle ukwenza i-weld.
a.Akukho mandla angaphandle aya kwenziwa kwiworkpiece
Xa umatshini we-laser welding obambe ngesandla uqhuba amacandelo, kuba akayi kudibana namalungu acutshungulweyo, akuyi kubakho uxinzelelo lwangaphandle kwiindawo ezicutshungulweyo ngexesha lenkqubo yonke yokuwelda, kwaye ugxininiso lwamandla olwenziwa yilaser lukhulu kakhulu. phezulu.Impembelelo ye-thermal kwindawo ejikeleze inxalenye incinci, ngoko ke inxalenye ayiyi kuphazamiseka ngexesha le-welding.
b.Ukuwelda phakathi kwezixhobo ezahlukeneyo kunokufezekiswa
Kwinkqubo yemveli yokuwelda, ngokuqhelekileyo zimbini kuphela izinto zokusebenza ezenziwe ngezinto ezifanayo ezinokudityaniswa, kodwa inkqubo yokuwelda yelaser yomatshini wokuwelda obambe ngesandla we-laser awukwazi nje ukuwelda indawo ephezulu yokunyibilika kunye nezixhobo ezahlukeneyo ekunzima ukunyibilika kunye nokuwelda. , Njenge-titanium alloy, i-aluminium alloy kunye nezinye izinto.Ukongeza, itekhnoloji ye-laser ye-welding processing inokuqonda ukuwelda phakathi kwezinto ezingafaniyo, ukwaphula umda we-welding phakathi kwemathiriyeli.
c.Umthungo we-welding encinci, ucocekile kwaye ubukeka obuhle
Itekhnoloji ye-laser yokuwelda yomatshini wokuwelda we-laser obambe ngesandla uhambele phambili kakhulu, ayingcolisi nje indawo esingqongileyo, kodwa ikwayila amalungu amancinci e-solder, i-welding seams emxinwa, i-uniform ye-welding seam structure, iipores ezimbalwa kakhulu kunye neziphene, ezinokunciphisa kwaye Ukwandisa ukungcola kwezinto zomzali, Ngoko ke, emva kwe-welding, kungekhona kuphela ukuchasana okuhlukeneyo, kodwa umphezulu wezinto eziphathekayo ucocekile kwaye uhle kakhulu.
