Wɔ dade a wɔyɛ ho adwuma mu no, .MFDC (Medium Frequency Direct Current) a wɔde wɔn ho hyɛ mu a wɔde wɔn ho hyɛ muyɛ welding nnwinnade a ɛho hia, na wɔn welding su nya nneɛma a wɔyɛ no pintinn ne ahobammɔ so nkɛntɛnso tẽẽ. Nanso ɛtɔ mmere bi a bere a wɔreyɛ welding no, yebetumi ahyia ɔhaw a ɛne sɛ ahurututu bɛpue wɔ mmeae a wɔde weld no ayɛ no. Ɛnyɛ sɛ eyi ka weld no fɛ nko na mmom ebetumi aka n’ahoɔden nso wɔ ɔkwan a enye so. Saa asɛm yi twe adwene si asɛmti "Dɛn nti na ahurututu wɔ spot weld points of."MFDC spot welders a wɔyɛ?", hwehwɛ nea ɛde ba no mu, na ɛde ano aduru a ɛne no hyia ma.
Nea ɛde ba no mu nhwehwɛmu
- Efĩ a ɛwɔ soro:Sɛ wɔanhohoro dade no ani yiye ansa na wɔayɛ welding a, efĩ a aka te sɛ ngo, efĩ, ne oxides betumi ama mframa afi welding ɔhyew a ɛkɔ soro no ase, na ayɛ ahurututu.
- Nneɛma a Ɛyɛ Nwonwa:Nneɛma a ɛyɛ hyew a efi nneɛma a wɔde yɛ welding no mu anaa nneɛma a atwa ho ahyia te sɛ paint anaa srade betumi ayɛ nwini bere a wɔayɛ no hyew no. Saa mframa yi kɔhyɛ ɔtare a ayow no mu, na ɛyɛ ahurututu.
- Mframa a Wɔtwetwe:Ebia dade nneɛma bɛtwe mframa te sɛ hydrogen anaa oxygen bere a wɔreyɛ welding no. Sɛ ɛhɔ hyew kɔ soro a, mframa yi fi adi, na ɛma ahurututu ba.
- Welding Parameters a Ɛmfata:Nsiesiei a ɛnteɛ ma parameters te sɛ welding current, bere, ne pressure betumi ama mpɔtam hɔ ɔhyew a ɛboro so anaasɛ ɔhyew a ɛnnɔɔso wɔ welding nneɛma no mu, na ɛde bubbles aba.
- Dade a Ɛyɛ Nsuo:Sɛ ɛyɛ hyew kɛse a, dade no fã bi betumi ayɛ nwini abɛyɛ nsu a ɛyɛ hyew. Sɛ saa nsuonwini yi dwo na ɛyɛ nwini a, ebetumi nso ayɛ ahurututu.
- Nneɛma a Wɔde Yɛ Welding a Ɛnhyia:Nnuru a entumi nnyina nneɛma ahorow ntam no betumi ama ahurututu ayɛ.
- Gas a Ɛbɔ Ho Ban Ho Nsɛm:Ɔhaw ahorow te sɛ mframa a ɛbɔ ho ban no ho tew a ɛnnɔɔso anaasɛ nsu a ɛtwetwe wɔ gas nhama no mu no betumi ama mframa a ɛbɔ ho ban yiye bere a wɔreyɛ welding no, na akyiri yi ɛde ahurututu aba.
Ano aduru ahorow
- Ma Ahotew Nkɔ anim:Hwɛ sɛ wɔahohoro dade no ani yiye ansa na woayɛ welding na ayi ngo, efĩ, ne oxides afi hɔ, na ɛtew mframa a efi mu ba no so.
- Di Nneɛma a Atwa Yɛn Ho Ahyia So:Kwati sɛ wobɛbɔ welding wɔ mmeae a nneɛma a ɛyɛ hyew wom, anaasɛ yɛ degreasing ne cleaning components ansa na welding.
- Yɛ Welding Parameters no yiye:Set parameters te sɛ welding mprempren, bere, ne nhyɛso ntease mu sɛnea welding nneɛma ne nhyehyɛe ahwehwɛde ahorow te na wɔakwati mpɔtam hɔ ɔhyew a ɛboro so anaasɛ ɔhyew a ɛnnɔɔso.
- Paw Nneɛma a Ɛfata a Wɔde Yɛ Welding:Hwɛ sɛ nneɛma a wɔde yɛ welding no hyia na wɔakwati nnuru a entumi nnyina.
- Hwɛ na Hwɛ Shielding Gas System no so:Hwɛ sɛ mframa a ɛbɔ ho ban no ho tew (hwɛ sɛ ɛboro 99.7%); hwɛ gas nhama no mu daa sɛ nsu nkɔ mu anaa na hwɛ hu sɛ ɛho tew; hwɛ sɛ solenoid valve a ɛhwɛ shielding gas a ɛwɔ welder no mu no reyɛ adwuma yiye anaa.
- Hohoro Nozzle no ho Daa:Spatter betumi abata nozzle no ho bere a wɔreyɛ welding no, na ɛka gas ahobammɔ. Enti, tew nozzle no ho daa, mpɛn pii no wɔkamfo kyerɛ sɛ simma 20-30 biara.
- Wɔn a Wɔyɛ Keteke Dwumadi:Hyɛ ntetee a wɔde ma adwumayɛfo no mu den na ama wɔn ntease a wɔwɔ wɔ welding nhyehyɛe ne nnwinnade ho no atu mpɔn, ahwɛ ahu sɛ wɔyɛ adwuma a wɔahyɛ da ayɛ ne parameter nhyehyɛe a ntease wom.
Sɛ yɛbɛbɔ no mua a, nea ɛde bubbles ba wɔ weld points ofMFDC spot welders a wɔyɛyɛ nea ɛyɛ den na egu ahorow. Nanso, ɛdenam nneɛma te sɛ ahotew a wɔama anya nkɔso, nneɛma a atwa yɛn ho ahyia sohwɛ, parameter optimization, nneɛma a wɔpaw, shielding gas system siesie, daa nozzle ahotew, ne adwumayɛfo ntetee a yɛde bedi dwuma so no, yebetumi atew anaasɛ yɛbɛkwati bubble a ɛba no yiye, na yɛnam saayɛ so ama welding no atu mpɔn.
