Nanso, bere a wɔreyɛ welding no, zinc a wɔde akata so no betumi ayɛ vaporized, na ama apetepete, ayɛ porosity, na weld ahoɔden so atew.
Spot welder a ɛyɛ den na ɛyɛ pɛpɛɛpɛ a wobɛpaw-titiriw a spot welding afiri a wɔde yɛ nneɛma-yɛ nea ɛho hia kɛse. Nanso afiri a eye sen biara mpo hwehwɛ sɛ wosiesie no yiye na ama wɔahwɛ ahu sɛ weld no yɛ papa bere tenten-.
Nnwumayɛbea data kyerɛ sɛ nsiesie nhyehyɛe a wɔahyehyɛ no yiye -tumi tew weld sintɔ so 20–40% na nnwinnade a huammɔdi so bɛboro 30%. Akwankyerɛ a ɛkɔ akyiri a wobetumi de adi dwuma wɔ nsiesie ho ni.
1. Electrode a Wɔhwɛ So Daa: Ade Safoa a Ɛma Welds Ayɛ Den
Asɛm a ɛtaa ba bere a wɔreyɛ dade a wɔde galvanized ayɛ no welding ne zinc a ɛbata electrode no so, a ɛhaw mprempren nsu a ɛsen ne weld a ɛkɔ so pɛpɛɛpɛ no.
Akwankyerɛ a Wɔde Siesie Electrode:
- Mpɛn dodow a wɔhwehwɛ mu:Hwɛ weld biara 80–120 (egyina zinc kɛse ne nneɛma batch so) .
- Ɔkwan a wɔfa so twitwa nneɛma:
Fa grinding wheel anaa electrode trimmer a wɔahyira so di dwuma
Ma electrode no ano nyɛ pɛpɛɛpɛ na woakwati sɛ ɛnsɛe pɛpɛɛpɛ
Tip angle a wɔkamfo kyerɛ: 60–120 degree
- Sua electrode cap tentendaa sɛnea ɛbɛyɛ a wɔrensɛe dodo
Nnwumayɛbea Ho Nsɛm (IIW):
Systematic trimming betumi atrɛw electrode nkwa mu 15–25% na ama weld consistency atu mpɔn bɛyɛ 20%.
2. Cooling System Maintenance: Siw Electrode Burnout ne Ɔhyew a Ɛporɔw no ano
Dade a wɔde galvanized ayɛ no hia ɔhyew a ɛkɔ soro, na ɛma ɔhyew a wɔde di dwuma ho hia kɛse.
Daa Daa Nhwehwɛmu:
- Nsuo a ɛma onwini sen 2 L/min anaasɛ ɛyɛ pɛ
- Ɔhyew a ɛkɔ soro Ennu anaasɛ ɛne digrii 8–10 yɛ pɛ
- Nsuo a ɛfiri mu ba no hyeɛ a ɛnnu digrii 30 anaasɛ ɛne no yɛ pɛ
Nnawɔtwe Biara Nhwehwɛmu:
- Hohoro filters ho na yi scale ne nneɛma a asɛe no afi hɔ
- Hwɛ sɛ hose ahorow no mu apaapae, ayɛ petee, anaasɛ asiw anaa
Onwini a ɛnsɛ betumi ama weld ahorow no ayɛ basaa, ama electrode no asɛe ntɛmntɛm, na ama transformer no ayɛ hyew dodo ho kɔkɔbɔ ahorow.
3. Optimize MFDC Welding Parameters: Tew Zinc Evaporation na Tu mpɔn Weld Ahoɔden
MFDC spot welders a wɔyɛma mprempren a ɛyɛ den ne ɔhyew a wɔde di dwuma pɛpɛɛpɛ, a eye ma dade a wɔde galvanized ayɛ.
Parameter Nsakrae a Wɔkamfo Kyerɛ:
- Welding mprempren:20–30% a ɛba fam sen AC welders a wɔtaa de di dwuma
- Weld bere:Wɔatwa no tiaa 10–20% .
- Nhyɛsoɔ:Ma ɛntena hɔ pintinn na ama porosity no ayɛ ketewaa bi
Mfaso a ɛwɔ MFDC Mfiridwuma so:
- 800–2000Hz frequency → ɛma ɔhyew a ɛyɛ adwuma yiye no kɔ soro 15–20% .
- DC a ɛkɔ so ba → kwati AC zero-cross nsakrae
- Millisecond-level control (0.25ms) → hwɛ hu sɛ weld no yɛ pɛpɛɛpɛ
- Nsu a wɔde petepete so no so tew na ɛmaa nugget ahoɔden tu mpɔn
4. Asase Ahosiesie: Tew Welding Mfomso
Ngo, oxidation, ne nneɛma a wɔde kata dade a wɔde galvanized ayɛ so no betumi atew weld no so.
Ahosiesie a Wɔkamfo Kyerɛ wɔ Fam Fam:
- Fa nsa anaa nnuru a wɔde yi srade a ɛnyɛ nea ɛhaw nneɛma a atwa yɛn ho ahyia yi ngo
- Yam brɛoo na ama oxides afi mu
- Fa mframa a wɔahyɛ no den bɔ mfutuma
- Optional: low-ɔhyew plasma ahotew ma high-precision welding
Ahosiesie a ɛfata a wɔyɛ wɔ soro no betumi atew weld porosity so 30–50%.
5. Fa nhyehyeɛ a ɛfa nsiesie ne dwumadie ho si hɔ (enhanced version wɔ hɔ).
