Nsogbu na ngwọta metụtara usoro ịgbado ọkụ nke nnukwu efere ma dị mkpa

1. Gịnị ka a ga-eme ma ọ bụrụ na ọkpụrụkpụ nke ígwè workpiece karịrị kacha ịgbado ọkụ ugbu a na ịgbado ọkụ igwe nwere ike nweta mgbe eji gas metal arc ịgbado ọkụ (GMAW) na flux cored waya gas arc ịgbado ọkụ (FCAW) ka weld ígwè workpieces?

Ihe ngwọta bụ ịgbanye ígwè ahụ tupu ịgbado ọkụ. Preheat ebe ịgbado ọkụ nke workpiece na-eji propane, ọkọlọtọ gas ma ọ bụ acetylene ịgbado ọkụ ọkụ, na a preheating okpomọkụ nke 150-260 ℃, wee gaba na ịgbado ọkụ. Ebumnuche nke ikpocha ọla na mpaghara ịgbado ọkụ bụ iji gbochie mpaghara weld ka ọ dị jụụ ngwa ngwa, ka ọ ghara ime ka mgbawa ma ọ bụ ngwakọta ezughị ezu na weld.

2. Ọ bụrụ na ọ dị mkpa iji agbaze electrode gas na-echebe ịgbado ọkụ ma ọ bụ flux cored waya gas na-echebe ịgbado ọkụ ka weld a mkpa mkpuchi metal n'elu a thicker ígwè ọkpọkọ, ma ọ bụrụ na ịgbado ọkụ ugbu a enweghị ike gbanwee n'ụzọ ziri ezi n'oge ịgbado ọkụ, o nwere ike iduga n'ọnọdụ abụọ:

Otu bụ iji belata ịgbado ọkụ ugbu a iji gbochie mkpa metal si na-ere ọkụ, na n'oge a, mkpa mkpuchi metal enweghị ike welded na oké ígwè ọkpọkọ; Nke abuo, oke ịgbado ọkụ ugbu a nwere ike na-ere site na mkpa okpu ígwè. Kedu ka esi edozi nke a?

Enwere ụzọ ụzọ abụọ:

① Gbanwee ịgbado ọkụ ugbu a ka ịzena ọkụ site mkpa metal cover, preheat oké ígwè ọkpọkọ na a ịgbado ọkụ ọkụ, na mgbe ahụ na-eji mkpa efere ịgbado ọkụ technology ka weld abụọ metal owuwu.

② Gbanwee ịgbado ọkụ ugbu a na-adabara maka ịgbado ọkụ nchara ọkpọkọ. Mgbe ịgbado ọkụ, nọgide na-ebi oge nke ịgbado ọkụ arc na oké ígwè ọkpọkọ na 90% na ibelata ebe obibi na mkpa mkpuchi metal. Ekwesịrị igosi na ọ bụ naanị mgbe ọkachamara na usoro a nwere ike nweta ezigbo nkwonkwo ịgbado ọkụ.

3. Mgbe ị na-agbado ọkpọkọ gbara okirikiri ma ọ bụ akụkụ akụkụ anọ dị mkpa ka ọ bụrụ nnukwu efere, mkpanaka ịgbado ọkụ na-adịkarị ọkụ site na akụkụ ọkpọkọ nwere mgbidi. Ewezuga ihe ngwọta abụọ a dị n'elu, enwere ihe ngwọta ọzọ?

Ee, tumadi iji mkpanaka ikposa ọkụ n'oge usoro ịgbado ọkụ. Ọ bụrụ na a na-etinye mkpanaka siri ike gburugburu n'ime tube okirikiri dị mkpa, ma ọ bụ a na-etinye mkpanaka akụkụ anọ siri ike n'ime ihe kwesịrị ekwesị nke akụkụ anọ, mkpanaka siri ike ga-ewepụ okpomọkụ nke ihe na-arụ ọrụ nke dị mkpa ma gbochie ọkụ. N'ikwu okwu n'ozuzu, a na-etinye mkpanaka siri ike gburugburu ma ọ bụ akụkụ anọ n'ime ọtụtụ ihe ndị a na-enye oghere ma ọ bụ akụkụ anọ. Mgbe ị na-agbado ọkụ, ekwesịrị ịṅa ntị na idobe weld ahụ site na njedebe nke ọkpọkọ, nke bụ ebe kachasị mfe ọkụ. Eserese nke iji igwe ọkụ arụnyere n'ime ya ka ọ ghara ịgba ọkụ ka egosiri na eserese 1.

4. Kedu otu esi eji galvanized ma ọ bụ chromium nwere welded n'akụkụ ọzọ?

Usoro kachasị mma bụ ịgbanye ma ọ bụ kpochaa ebe dị n'akụkụ weld tupu ịgbado ọkụ, n'ihi na galvanized ma ọ bụ chromium nke nwere efere ígwè ọ bụghị nanị na-emerụ ma mee ka weld dị ike, kamakwa na-ahapụ gas na-egbu egbu n'oge ịgbado ọkụ.
