Njirimara na Ngwa Ngwakọta Argon-Hydrogen na Welding
Ngwakọta argon-hydrogenenwetala nlebara anya dị ukwuu n'ọhịa nke ịgbado ọkụ n'ihi ihe ha pụrụ iche na ọtụtụ ngwa ngwa. Isiokwu a na-achọ inyocha ihe dị iche iche nke ngwakọta argon-hydrogen ma kparịta ngwa ha na usoro ịgbado ọkụ. Site n'ịghọta akụrụngwa na ngwa ndị a, welders nwere ike bulite usoro ịgbado ọkụ ha wee nweta welds dị elu.
1. Njirimara Argon-Hydrogen Ngwakọta:
1.1 Mmụba Ọkụ Ọkụ: Ngwakọta Argon-hydrogen nwere ikuku okpomọkụ dị elu ma e jiri ya tụnyere argon dị ọcha. Nke a na-ebute ntinye ọkụ na-abawanye n'oge usoro ịgbado ọkụ, na-eduga n'ịbanye mma na ịgbado ọkụ ngwa ngwa.
1.2 Enwekwukwa Arc Stability: Mgbakwunye nke hydrogen na argon na-eme ka nkwụsi ike arc dị mma site n'ibelata nkwụsị voltaji gafee arc. Nke a na-enye ohere ijikwa usoro ịgbado ọkụ nke ọma, na-ebelata spatter na hụ na arc kwụsiri ike na weld niile.
1.3 Ọganihu Nchekwa Mma: Ngwakọta Argon-hydrogen na-enye ihe nchebe dị mma, na-egbochi mmetọ ikuku nke ọdọ mmiri weld. Ọdịnaya hydrogen dị na ngwakọta na-arụ ọrụ dị ka gas na-emeghachi omume, na-ewepụ nke ọma oxides na adịghị ọcha ndị ọzọ na mpaghara weld.
1.4 Mbelata Okpomọkụ Na-emetụta Mpaghara (HAZ): Iji ngwakọta argon-hydrogen na-eme ka HAZ dị warara na nke na-adịghị emetụta ma e jiri ya tụnyere gas ndị ọzọ na-echebe. Nke a bara uru karịsịa maka ihe ịgbado ọkụ nwere ọkụ ọkụ dị elu, n'ihi na ọ na-ebelata mgbagwoju anya ma na-eme ka ọ dị mma weld n'ozuzu ya.
2. Ngwa nke Argon-Hydrogen Ngwakọta na Welding:
2.1 Carbon Steel Welding: A na-ejikarị ngwakọta argon-hydrogen maka ịgbado ọkụ carbon n'ihi ikike ha inye ntinye miri emi na ọsọ ịgbado ọkụ dị elu. Nkwụsi ike nke arc na nkwalite ihe nchebe na-eme ka ngwakọta ndị a dị mma maka ịnweta welds siri ike na nke na-adịgide adịgide na ngwa carbon ígwè.
2.2 Igwe anaghị agba nchara: Ngwakọta argon-hydrogen dịkwa mma maka ịgbado ọkụ igwe anaghị agba nchara. Ọdịnaya hydrogen dị na ngwakọta na-enyere aka iwepụ oxides elu, na-ebute welds dị ọcha na obere porosity. Na mgbakwunye, ntinye ọkụ na-abawanye na-enye ohere maka ịgbado ọkụ ngwa ngwa, na-eme ka nrụpụta n'ime igwe anaghị agba nchara.
2.3 Aluminom Welding: Ọ bụ ezie na a na-ejikarị argon-helium ngwakọta maka ịgbado ọkụ aluminom, a pụkwara iji ngwakọta argon-hydrogen rụọ ọrụ. Ngwakọta ndị a na-enye nkwụsi ike nke arc ka mma yana arụ ọrụ nhicha dị mma, na-eme ka welds dị elu nwere ntụpọ belata.
2.4 Copper Welding: Enwere ike iji ngwakọta Argon-hydrogen maka ịgbado ọkụ ọla kọpa, na-enye nkwụsi ike arc dị mma na ntinye ọkụ ka mma. Ọdịnaya hydrogen dị na ngwakọta na-enyere aka iwepu ọla kọpa oxides, na-eme ka welds dị ọcha na nke siri ike.
Ngwakọta argon-hydrogen nwere ihe pụrụ iche na-eme ka ha dabara nke ọma maka ngwa ịgbado ọkụ dị iche iche. Ntinye ọkụ ha na-abawanye, nkwụsi ike arc kwalitere, ihe nchebe dị mma, na belata HAZ na-eme ka ha bụrụ nhọrọ magburu onwe ya maka ígwè carbon, igwe anaghị agba nchara, aluminum, na ịgbado ọla kọpa. Site n'iji argon-hydrogen ngwakọta, welders nwere ike nweta welds dị elu na-arụpụta ihe ka mma yana mbelata ntụpọ. Ọ dị mkpa maka ndị welders ịghọta njirimara na ngwa nke ngwakọta argon-hydrogen iji kwalite usoro ịgbado ọkụ ha wee hụ na ọ ga-arụpụta nke ọma na ọrụ ịgbado ọkụ ha.
