5. Nchekwa gas nke Ngwa anya Systems
Igwe ọkụ laser na-elekwasị anya na mpaghara ịgbado ọkụ site na usoro ngwa anya. N'oge a na-ere ahịa, ihe a wụrụ awụ na ikuku ikuku na-emepụta nwere ike imerụ ngwa anya. Site n'iwebata gas na mpaghara ịgbado ọkụ, ihe ize ndụ nke mmetọ na-ebelata na ndụ nke usoro anya na-agbatị.
Na ịgbado ọkụ laser, gas nwere ike kewapụ ikuku na efere ịgbado ọkụ ma gbochie ya imeghachi omume na ikuku. N'ụzọ dị otú a, welding elu nke metal efere ga-adị ọcha ma mara mma. Iji gas na-echebekwa anya anya n'uzuzu ịgbado ọkụ. Ọtụtụ mgbe, a na-eji gas ndị a:
1. Nchekwa gas:
Gasị nchekwa, mgbe ụfọdụ a na-akpọ “gas inert,” na-arụ ọrụ dị mkpa na usoro ịgbado ọkụ laser. Usoro ịgbado ọkụ nke laser na-ejikarị gas inert kpuchie ọdọ mmiri weld. Gasị nchebe a na-ejikarị na ịgbado ọkụ laser gụnyere argon na neon. Njirimara anụ ahụ na kemịkal ha dị iche, yabụ mmetụta ha na weld dịkwa iche iche.
·Argon: Argon bụ otu n'ime ikuku inert a na-ejikarị eme ihe. Ọ nwere ogo dị elu nke ionization n'okpuru ọrụ nke laser, nke na-adịghị mma ịchịkwa nhazi nke ígwé ojii plasma, nke ga-enwe mmetụta ụfọdụ na iji laser dị irè. Ọdịdị inert nke argon na-eme ka ọ ghara ịdị na-eme ka ọ ghara ịdị na-ere ahịa, ebe ọ na-ekpochapụkwa okpomọkụ nke ọma, na-enyere aka ịchịkwa okpomọkụ na mpaghara ebe a na-ere ere.
·Neon: A na-ejikarị Neon eme ihe dị ka gas inert, dị ka argon, a na-ejikwa ya echebe ebe ịgbado ọkụ site na ikuku oxygen na ihe ndị ọzọ na-emerụ emerụ na gburugburu ebe obibi. Ọ dị mkpa ịmara na neon adịghị mma maka ngwa ịgbado ọkụ laser niile. A na-eji ya eme ihe maka ụfọdụ ọrụ ịgbado ọkụ pụrụ iche, dị ka ịgbado ọkụ ihe ndị gbara ọkpụrụkpụ ma ọ bụ mgbe achọrọ akwa weld miri emi.
2. Gas inyeaka:
N'oge usoro ịgbado ọkụ laser, na mgbakwunye na isi ihe nchebe, a pụkwara iji gas inyeaka mee ka ọrụ ịgbado ọkụ dịkwuo mma na ịdị mma. Ndị a bụ ụfọdụ gas inyeaka a na-ejikarị eme ihe na ịgbado ọkụ laser:
· Oxygen: A na-ejikarị oxygen mee ihe dị ka gas na-enyere aka ma nwee ike iji mee ka okpomọkụ na ịdị omimi weld n'oge ịgbado ọkụ. Ịgbakwunye oxygen nwere ike ịbawanye ọsọ ịgbado ọkụ na ịbanye, mana ọ dị mkpa ka ejiri nlezianya chịkwaa ya iji zere oke ikuku oxygen na-akpata nsogbu oxidation.
· Nitrogen: Nitrogen na-ejikarị dị ka gas inyeaka na ịgbado ọkụ laser. Ike ionization nke nitrogen dị oke oke, dị elu karịa argon na ala karịa hydrogen. Ogo ionization na-adịkarị n'okpuru ọrụ nke laser. Ọ nwere ike belata nguzobe nke ígwé ojii plasma nke ọma, nye welds dị elu na ọdịdị dị elu, ma belata mmetụta oxygen na welds. Enwere ike iji nitrogen chịkwaa okpomọkụ nke ebe ịgbado ọkụ ma belata nguzobe nke egosipụta na pores.
· Ngwakọta Hydrogen/Hydrogen: Hydrogen na-eme ka welds dị mma ma belata nguzobe nke porosity. A na-eji ngwakọta nke argon na hydrogen eme ihe na ụfọdụ ngwa pụrụ iche, dị ka ịgbado ọkụ igwe anaghị agba nchara. Ọdịnaya hydrogen nke ngwakọta na-adịkarị site na 2% ruo 15%.
·Helium: A na-ejikarị helium eme ihe maka ịgbado ọkụ laser dị elu n'ihi na ọ nwere conductivity dị ala na ọ naghị adị mfe ionized, na-ekwe ka laser gafere nke ọma na ike ọkụ ahụ ruo n'elu workpiece na-enweghị ihe mgbochi ọ bụla. Na-enyere aka ịgbado ọkụ dị elu. Enwere ike iji helium kwalite ogo weld yana ịchịkwa okpomọkụ ịgbado ọkụ. Nke a bụ gas mkpuchi kachasị dị irè nke ejiri na ịgbado ọkụ laser, mana ọ dị oke ọnụ.
3. gas jụrụ oyi:
A na-ejikarị gas jụrụ oyi n'oge ịgbado ọkụ laser iji chịkwaa okpomọkụ nke ebe ịgbado ọkụ, gbochie ikpo oke ọkụ, ma nọgide na-enwe ogo ịgbado ọkụ. Ndị a bụ ụfọdụ gas jụrụ oyi na-ejikarị:
·Mmiri: Mmiri bụ ihe na-eme ka ọ dị jụụ nke a na-ejikarị eme ihe iji mee ka ndị na-emepụta ihe na-emepụta laser na usoro ịgbado ọkụ laser. Usoro mmiri jụrụ oyi nwere ike inye aka ịnọgide na-enwe okpomọkụ nke laser generator na ngwa anya iji hụ na nkwụsi ike na arụmọrụ laser.
·Igwe ikuku ikuku: N'ụfọdụ usoro ịgbado ọkụ laser, ikuku ikuku nwere ike iji mee ka ọ dị jụụ. Dịka ọmụmaatụ, na usoro ngwa anya nke laser generator, ikuku ikuku gbara ya gburugburu nwere ike inye mmetụta dị jụụ.
·Gases inert: A pụkwara iji gas na-adịghị arụ ọrụ dị ka argon na nitrogen mee ihe dị ka gas jụrụ oyi. Ha nwere conductivity thermal dị ala ma nwee ike ijikwa ọnọdụ okpomọkụ nke ebe ịgbado ọkụ ma belata mpaghara okpomọkụ emetụtara (HAZ).
·Nitrogen Liquid: Liquid nitrogen bụ ihe na-ajụ oyi nke ukwuu nke enwere ike iji maka ịgbado ọkụ laser dị oke elu. Ọ na-enye mmetụta dị jụụ dị irè ma na-eme ka njikwa okpomọkụ dị na mpaghara ịgbado ọkụ.
4. Ngwakọta gas:
A na-ejikarị ngwakọta gas eme ihe na ịgbado ọkụ iji kwalite akụkụ dị iche iche nke usoro a, dị ka ọsọ ịgbado ọkụ, omimi ntinye, na nkwụsi ike arc. Enwere isi ihe abụọ nke ngwakọta gas: ọnụọgụ abụọ na ternary.
1. Ngwakọta gas ọnụọgụ abụọ:
·Argon + Oxygen: Ịtinye obere oxygen na argon na-eme ka nkwụsi ike arc dịkwuo mma, na-eme ka ọdọ mmiri weld dịkwuo mma, ma na-abawanye ọsọ ịgbado ọkụ. A na-ejikarị ngwakọta a eme ihe maka ịgbado ọkụ carbon ígwè, obere alloy steel, na igwe anaghị agba nchara.
·Argon + Carbon Dioxide: mgbakwunye CO₂ na argon na-abawanye ike ịgbado ọkụ na nguzogide corrosion ma na-ebelata spatter. A na-ejikarị ngwakọta a eme ihe maka ịgbado carbon steel na igwe anaghị agba nchara.
·Argon + Hydrogen: Hydrogen na-abawanye okpomọkụ arc, na-eme ka ọsọ ịgbado ọkụ na-ebelata, na-ebelata ntụpọ ịgbado ọkụ. Ọ bara uru karịsịa maka ịgbado ọkụ na nickel alloys na igwe anaghị agba nchara.
2. Ngwakọta gas Ternary:
·Argon + Oxygen + Carbon Dioxide: Ngwakọta a na-ejikọta abamuru nke ma argon-oxygen na argon-CO₂ ngwakọta. Ọ na-ebelata spatter, na-eme ka mmiri mmiri weld ọdọ mmiri dịkwuo mma, ma na-eme ka ịdịmma weld dịkwuo mma. A na-eji ya ọtụtụ ebe maka ịgbado ọkụ dị iche iche ọkpụrụkpụ nke carbon ígwè, ala alloy ígwè, na igwe anaghị agba nchara.
·Argon + Helium + Carbon Dioxide: Ngwakọta a na-enyere aka melite nkwụsi ike arc, na-abawanye okpomọkụ ọdọ mmiri, ma na-eme ka ịgbado ọkụ ọsọ. A na-eji ya na mgbado arc dị mkpụmkpụ na ngwa ịgbado ọkụ dị arọ, na-enye njikwa kacha mma karịa oxidation.
