Uburyo bwo guhitamo gaze irinda umutekano ikwiye mu gukoresha insinga za MIG

Guhitamo gazi yo kurinda ikoreshwa nabi bishobora kugusiga ufite imyenge yuzuyemo imyenge, imitobe, cyangwa imbaraga nke—ndetse no mu gihe ukoresha insinga n'ibikoresho bya MIG bikomeye. Gazi yo gusudira ya MIG ishobora gusa n'aho itagaragara, ariko ni "formula y'urufunguzo rutagaragara" igira ingaruka ku miterere y'icyuma, uburyo bwo kohereza ibyuma, ndetse n'imiterere ya nyuma ya mashini yo gusudira. Hasi, turasesengura uburyo bworoshye bwo gufata ibyemezo kugira ngo bigufashe guhitamo gazi yo kurinda ikoreshwa ryawe.

Gahunda y'ibyemezo: Shaka Gazi Itunganye Irinda Uburinzi

Tuzasuzuma ibibazo bitatu by'ingenzi kugira ngo tugabanye amahitamo yawe. Nta gukekeranya ukundi—amahitamo yihariye ashingiye ku byo ukeneye by'ukuri.

Ikibazo cya 1: Ni ibihe bikoresho urimo gusudira?

Ibikoresho ni cyo kintu cya mbere kandi cy'ingenzi cyane. Reka dutangire n'ibisanzwe cyane hanyuma tujye ku byuma byihariye.

Ibyuma Bito (Ibintu Bikunze Kubaho)

Ku bijyanye na gazi yo gusudira icyuma cyoroshye ukoresheje insinga ikomeye ya MIG, hari amahitamo abiri yiganje ku isoko. Dore uko bingana:

Gazi ya C25 (75% Ar, 25% CO2) – Amahitamo ya mbere ku isi yose

Impamvu ikora: Iyi mvange ya argon CO2 itanga umurambararo uhamye, isesagura rito cyane, kandi igaragara neza nk'iy'ubushuhe—ikemura ibibazo bikomeye byo gusudira byoroheje mu byuma. Igabanya igihombo cy'ibintu bya alloy, yongera imbaraga zo gukurura ubushuhe, kandi ikora ku bikorwa byinshi, kuva ku mpapuro nto kugeza ku masahani y'ubunini buri hagati. Waba ukora akazi ko gusohora amashanyarazi make cyangwa kohereza spray, C25 ikomeza gukora neza kandi ikagenzurwa.C25

Ibyiza kuri: Imirimo myinshi y'icyuma cyoroheje aho ireme, imiterere, n'uburyo bworoshye bwo gukora ari ingenzi.

CO2 nziza - Ihindagurika rizigama ikiguzi

Impamvu ikoreshwa: CO2 y'umwimerere ihendutse cyane ugereranyije n'imyuka ivanze, bigatuma ikurura imirimo myinshi kandi ifite ingengo y'imari nto. Itanga kandi uburyo bwo kwinjira mu buryo bwimbitse, ibyo bikaba ingirakamaro mu gusudira plate nini idahinduka. Impinduka: Tegereza "umurambararo ukomeye", gusudira byinshi, n'ubuso bugoye gusudira. Uzamara igihe cy'inyongera mu gusukura nyuma yo gusudira, kandi igihombo cy'aloyi kiri hejuru ugereranije na C25.

Ibyiza kuri: Icyuma gikomeye cyoroheje aho imiterere idakomeye kandi ikiguzi ari cyo kintu cy'ingenzi kurusha ibindi.

Inama y'inzobere: Niba usudira icyuma cyoroheje cyane kandi ukaba ushaka uburyo bwo gusukura kandi butagoranye, tangira kuri C25. Ni bwo buryo bwiza cyane bwo gukoresha insinga zikomeye za MIG.

Icyuma kitagira umwanda

Gazi yo gusudira icyuma kidashonga igomba kubungabunga ingese no gutuma isura yayo igaragara neza. Argon y'umwimerere ntabwo ikora hano—itera amazi mabi mu gusudira no kwangirika.成形Hitamo umwuka uvanze mu buryo butatu nka Ar + 2-5% CO2 + 1-2% O2 cyangwa Ar + 90% He + 2.5% CO2. Ibi bivanga bigabanya ubushyuhe bw'icyuma gishongeshejwe, binoza uburyo bwo gukwirakwiza ubushyuhe, kandi bigabanya igihombo cy'icyuma gishongeshejwe, bigatuma icyuma kidakora neza kigumana ubushobozi bwo kurinda icyuma kidakora neza.

Aluminium

Aluminiyumu ikenera argon nziza cyangwa uruvange rwa argon-helium. Akazi ka Argon k'ibanze ni ugusukura icyuma cya aluminiyumu oxide (ni ngombwa kugira ngo habeho imashini zikomeye zo gusudira) no gushimangira arc. Kongeramo helium byongera ubushyuhe, bifasha mu bice binini bya aluminiyumu binyuze mu kongera kwinjira no gusudira umuvuduko. Irinde CO2 cyangwa O2 mu mwuka urinda aluminiyumu—bizatera imyenge n'ingufu zo gusudira.

Ikibazo cya 2: Ni iyihe miterere y’ubusoda ushyira imbere?

Guhitamo kwa gazi bigira ingaruka zitaziguye ku kuntu isudira yawe isa n'uko ikora. Huza gazi n'imiterere y'ingenzi:

• Ukeneye amasaro manini yo gusudira no kwinjira mu buryo buciriritse (ni byiza ku mpapuro nto)? Koresha igipimo cya argon kiri hejuru - byoroshya arc kandi bikarinda gushya.
• Ukeneye kwinjira cyane kugira ngo ubone amasahani manini? Uruvange rwa CO2 cyangwa uruvange rwa CO2 ruri hejuru rutanga ubushyuhe bwinshi.
• Urashaka umuvuduko wo gusudira vuba? Argon-helium mixes cyangwa C25 bitanga amperage nyinshi nta gusuka cyane, bigatuma umusaruro wiyongera.
• Wanga gusukura nyuma yo gusudira? C25 cyangwa izindi mvange zikungahaye kuri argon bigabanya cyane uburyo bwo gusudira, bikakurinda umwanya wo gusya no kurangiza.

Ikibazo cya 3: Ingengo y'imari yawe ni iyihe?

Dukore ibintu mu buryo bufatika—ingengo y'imari ituma habaho gufata ibyemezo byinshi. Dore isesengura ry'ibiciro nyaryo, uretse igiciro cya lisansi gusa:

• CO2 y’umwimerere: Igiciro gito cya lisansi mbere y’igihe, ariko ikiguzi cy’igihe kirekire kiri hejuru bitewe n’igihe cy’inyongera cyo gusukura no kwiyongera kw’imyanda ikomeye ya MIG.
• Gazi ya C25: Ikiguzi cya gazi kiri hejuru ugereranyije na CO2 yuzuye, ariko ikiguzi rusange kiragabanuka bitewe n'umuvuduko wo gusudira wihuta no kongera gukora ku buryo budasubirwaho. Nta bikoresho by'inyongera bikenewe—silinda imwe gusa.
• Uruvange rw'ibivange bitatu cyangwa argon-helium: Igiciro kinini cy'ibikoresho byihariye, ariko ni ngombwa kugira ngo hirindwe ko ibintu byangiritse mu buryo buhenze.

Dore ikibazo: Niba ufite ingengo y'imari nto ariko ukoresheje icyuma cyoroshye cyane, CO2 isanzwe irashoboka—niba ukoresha igihe cyo kuyisukura. Ku maduka menshi, C25 itanga igiciro n'imikorere myiza.

Inama z'ingenzi: Ntugasenye amahitamo meza ya gazi hamwe n'imiterere mibi

Ndetse na gaze irinda neza ntabwo izagufasha kuzigama isudira yawe niba wangiza umuvuduko w'amazi cyangwa ukangiza gazi. Ibi bisobanuro ntibishobora kuganirwaho:

Igipimo cy'umuvuduko wa gaze (CFH/LPM)

Amazi make cyane atuma umuyoboro wawe w'amazi udakingirwa (bitera ubwinshi bw'amazi mu kirere); menshi cyane atera ubwinshi bw'amazi mu kirere (akurura umwuka, anatera ubwinshi bw'amazi mu kirere). Ku bijyanye n'insinga zikomeye za MIG:

• Icyuma cyoroshye (C25 cyangwa CO2 y'umwimerere): 15-25 LPM (30-50 CFH)
• Icyuma kidasesagura (tri-mix): 18-28 LPM (38-60 CFH)
• Aluminium (argon/argon-helium): 20-30 LPM (42-63 CFH)

Kumira kw'umwuka

Ubushuhe buri mu mwuka urinda ikirere ni ikintu cyica bucece. Butera ubushuhe bwo gusudira kandi bugatuma ibikoresho byo gusudira bigabanuka. Buri gihe koresha icyuma cyumisha/akayunguruzo mu murongo wa gazi yawe, kandi urebe neza ko silindiri zawe ziri hejuru ya 0.5 MPa (70 psi)—munsi y’uyu muvuduko, ubushuhe n’imyanda byiyongera muri gazi.

Ihame rya nyuma n'intambwe ikurikiraho

Itegeko ry'ingenzi: Huza gazi yawe ikingira n'ibikoresho byawe, shyira ubwiza n'igiciro, kandi buri gihe urebe ko gazi itangwa neza kandi ihagije. Ibi bikora neza, kandi ushyireho imbaraga zawe.Insinga ya MIGizakora neza cyane.

Iyo umaze guhitamo gaze irinda umutekano ikwiye, guhitamo insinga ikomeye ya MIG ijyanye na gaze n'ibikoresho byawe ni intambwe ikurikira yo kugera ku ntsinzi yo gusudira. Insinga ikomeye ya MIG ifasha mu gukora neza ibinyabutabire kandi ikanakoresha neza insinga—ikorana neza na gaze irinda umutekano wahisemo neza kugira ngo itange ubushuhe bukomeye kandi buhoraho buri gihe.
