(1) Ụdị na iwebata gas nchebe
Helium: dị oke ọnụ, mana kachasị dị irè, na-enye ohere ka laser gafere n'enweghị ihe mgbochi na ozugbo na elu nke workpiece.
Argon: dị ọnụ ala, denser, nchebe ka mma, elu nke weldment dị nro karịa helium, mana ọ nwere ike ịnweta ionization metal plasma dị elu, ga-echebe akụkụ nke osisi ahụ na workpiece, na-ebelata ike dị irè nke ịgbado ọkụ, ịgbado ọkụ ọsọ na omimi nke ngwakọta na-egbochi.
Nitrogen: dị ọnụ ala, ma ọ bụghị adabara ụfọdụ igwe anaghị agba nchara.
(2) Ọrụ nke gas nchebe
1. Chebe workpiece na ịgbado ọkụ usoro bụ oxidized, laser ịgbado ọkụ igwe eji nchebe gas, ịtọ na-echebe gas, na mgbe ahụ si na laser, nwere ike igbochi laser ịgbado ọkụ igwe na-aga n'ihu nhazi usoro, usu laser oxidation onu.
2. Chebe oghere na-elekwasị anya site na mmetọ vapor metal na mmiri mmiri na-agbapụta mmiri, karịsịa ịgbado ọkụ dị elu, n'ihi na ejecta dị ike nke ukwuu, ya mere ọ dị mkpa iji chebe oghere ahụ.
3. Gas na-echebe nwere ike imeziwanye àgwà nke weld nke ọma, gas dị iche iche nwere mmetụta dị iche iche na mmiri nke ọdọ mmiri a wụrụ awụ, wetting na ihe ndị ọzọ, si otú ahụ na-emetụta àgwà nke nhazi nke weld.
4. Gas na-echebe nke ọma nwere ike imeziwanye nnyefe ọkụ, meziwanye ojiji nke ike laser, si otú ahụ na-amụba ọsọ ịgbado ọkụ.
Ya mere, ọ dị ezigbo mkpa ịhọrọ gas nchebe ziri ezi maka ịgbado ọkụ laser ejiri aka. Ihe dị iche iche, usoro ịgbado ọkụ, na akụrụngwa akụrụngwa niile nwere mmetụta na nhọrọ nke mkpuchi gas. Naanị site na ịhọrọ gas na-echebe nke ọma, anyị nwere ike ịkwalite arụmọrụ nke igwe ịgbado ọkụ laser ejiri aka anyị wee nweta nsonaazụ ịgbado ọkụ dị elu.
