Laser ihicha na-arụ dị nnọọ oké mkpa na pretreatment nke ịgbado ọkụ na brazing. Na shipbuilding, nkenke ngwá ọrụ n'ichepụta, akpakanamde na ndị ọzọ yiri ọrụ, aluminum na ígwè ga-emeso ha tupu ha nwere ike welded.
Otu n'ime ọtụtụ ngwa maka laser ihicha bụ laser ịgbado ọkụ nkwadebe, nke na-enyere wepu nwa na-abụghị ferrous ọla, lubricants na ndị ọzọ na contaminants si metal na aluminum na-ebupụta na nkwadebe maka elu àgwà ịgbado ọkụ. Ọ na-ana achi achi a ezigbo onye na-abụghị porous brazed Weld.
Mgbe e ji maka tupu ọgwụgwọ nke ịgbado ọkụ na brazing, laser ihicha anamde ndị na-esonụ arụmọrụ:
◎ N'ịbụ wepu shop primer, hydrate na oxide oyi akwa
◎ Wepụ griiz na mmanụ
Ke adianade soldering na brazing nkwadebe, lasers nwere ike iji wepu solder fọduru, dị ka mmapụta agbanwe oge na oxide ihe, dị ka nke ọma dị ka na-ekpo ọkụ tụrụ na okokụre solder nkwonkwo.
The uru nke na-eji laser ihicha na jikọtara na brazing pretreatment na-agụnye:
◎ Kemeghi wavelength na ike kpọmkwem nhazi nkwonkwo na a dịgasị iche iche nke ihe onwunwe thicknesses
◎ No mmebi nke isi ihe onwunwe (ie na galvanized oyi akwa nke nchara efere)
