Mig ịgbado ọkụ - ngwa ngwa na rụọ ọrụ nke ọma

Ịgbado ọkụ - ọ bụ enweghị atụ usoro ikwe kasị reliably ma n'ụzọ ziri ezi igosi na-adịgide adịgide njikọ akụkụ ma ọ bụ akụkụ nke isiokwu mere nke ọla na ígwè kpụọ. Iji ụbọchị, mepụtara na emejuputa atumatu na mmepụta nke ọtụtụ ụzọ dị iche iche na usoro nke ịgbado ọkụ anọ na. Onye ọ bụla n'ime ụzọ nwere uru na ọghọm.

Otu n'ime ndị kasị ewu ewu na ịgbado ọkụ technology bụ a ọkara akpaka ịgbado ọkụ na a dịgasị iche iche nke na-echebe gas atmospheres. Ọ pụrụ ịrụ ọbụna ndị ọkachamara na iru eru ala karịa mkpa maka ntuziaka aak ịgbado ọkụ. Na nke a, na usoro na-ewe obere oge. Ihe Weld isiokwu technology bụ nke elu àgwà na-adịghị achọ ka ụdi-agba si slag. Ọzọkwa nhazi (primer, agba, wdg) welded ngwaahịa nwere ike na-enweghị-enweghị isi na-egbu oge. The ojiji nke ọkara akpaka anọ na ịgbado ọkụ na-enye ohere ejikọta nnọọ mkpa metal mpempe (0,1 - 1.5 mm), igosi ejikọta onuete tinyere curvilinear seams, nkwonkwo aka obere ókè. Ọ bụ ezigbo ịgbado ọkụ usoro maka obere-ọnụ ọgụgụ ma ọ bụ uka mmepụta.

The aha "semiautomatic" Nke a technology bụ karịsịa maka izipu. N'ezie, ọ bụ otu ihe aak ịgbado ọkụ pụrụ iche waya electrode nke a rụrụ na inert gas. Ụkpụrụ na nke dabeere ọkara akpaka ịgbado ọkụ, bụ nnọọ mfe. Feeder nri ịgbado ọkụ waya na-emepụta na a ngwaọrụ nnata, na mgbe ahụ na - na Weld mpaghara. pụrụ iche ngwa akara ngwaọrụ-eje ozi na-achịkwa waya electrode ọsọ.

Malite na-arụ ọrụ ahụ na-agụnye igodo n'out oge thereto nnyefe nke gas na waya. Tupu mmalite nke usoro mbara bu n'obi Weld onuete jupụtara na agbanwe agbanwe oge nke a pụrụ iche bonka. Excitation na-rụrụ aak eji ọganihu nke electrode tinyere welded n'ọnụ ebupụta mgbe electrode pitch na-gụnyere, ma ọ bụ mgbe ama ejikọrọ na ndepụta ma jupụta agbanwe oge. Ekemende anyị nwere akụ aka electrode n'ọnụ sikwuo ike slag, ma ọ bụrụ na aak na-anyụ na amụnyewo ọzọ. The usoro a na-emekarị rụrụ na nwetụ ugbu a, ọ bụ ezie na ọ na-ekwe omume iji na-adịgide adịgide.

Mig ịgbado ọkụ - a ikpe akpaghị aka usoro. N'ịga na njide tinyere onuete welder e mere site n'aka, na ihe ọ bụla ibu onye mesiri ike na ndị pụrụ iche kroochi na-etinye na ngwaahịa. Eji dị ka obere mkpanaaka na anyịnya feeders, nhọrọ adabere kpọmkwem ịgbado ọkụ ọrụ. The electrodes na-ahọrọ dị ka Njirimara nke welded metal na Weld e ji mara ga-enwetara. The echebe gas, achọ ịgbado ọkụ a rụrụ ọkara nwekwara họrọ dabeere na Njirimara nke welded ígwè. N'ihi na ala carbon ígwè echebe gas emepụta carbon dioxide (CO _2), argon nwere ike na etinyere ya. Gas na-ọnọ si a nozulu, displacing ikuku si ịgbado ọkụ ebe na ichebe onuete.

Site ịzụta na ịgbado ọkụ ngwá, ọtụtụ ndị na-azụ chọrọ na-enwe ike iji na-emepụta na-ịgbado ọkụ aluminum. N'ihi ọdịdị nke metal, ọkara akpaka ịgbado ọkụ nke aluminum bụ technologically ihe siri ike karịa compound ígwè ngwaahịa. Isi ike jikọtara ịrịba iche nke agbaze okpomọkụ nke aluminum (660 ° C) na-echebe film na ya elu (2200 ° C). Nweta a quality Weld penetration na ezi ọkara akpaka na argon gburugburu ebe obibi bụ na o kwere omume, ma ebe a na ihe niile ga-adabere na nkà, nkà ịrụ na nkà nke welder n'ịrụ ọrụ ahụ.
