FAQ
Asɛmmisa: Dɛn na ɛde welding spatter ba wɔ resistance spot welding mu?
A: Nea ɛde ba titiriw ne current anaa weld bere a ɛboro so, electrode ahoɔden a ɛnnɔɔso, squeeze bere a ɛnnɔɔso, fit-up a enye, soro tebea a ɛnhyia ne electrode a asɛe anaasɛ ɛnteɛ.
Asɛmmisa: Dɛn ne expulsion wɔ spot welding mu?
A: Expulsion ba bere a wɔtow dade a wɔabɔ no fi weld interface no mu wɔ welding cycle no mu. Wɔtaa ka ho asɛm sɛ spot welding spatter, nanso ɛsono no wɔ spatter a arc-welding nhyehyɛe de abɔ no ho.
Asɛmmisa: So welding current a ɛboro so ma spatter ba?
A: Yiw, current a ɛboro so betumi ama nugget anyin ntɛmntɛm na wɔapam no. Nanso, ɛnsɛ sɛ wɔtew current so kosi sɛ wɔbɛhwɛ electrode ahoɔden, squeeze time, fit-up ne surface condition nso.
Asɛmmisa: So electrode ahoɔden a ɛba fam betumi ama wɔapam weld?
A: Yiw. Ebia tumi a ɛnnɔɔso anaasɛ entumi nnyina dade a ayow no ntumi nsiw nkratafa no ntam. Ɛsɛ sɛ wɔhwɛ sɛ electrode ahoɔden ankasa no yɛ nokware sen sɛ wɔde wɔn ho bɛto mframa-nhyɛso nhyehyɛe no nkutoo so.
Asɛmmisa: Dɛn nti na spatter pue bere a wɔakɔ so ayɛ welding akyi nkutoo?
A: Electrode anim no betumi ayɛ hyew, asɛe anaasɛ aboaboa nneɛma ano bere a wɔreyɛ no. Ɛsɛ sɛ wɔhwɛ onwini adwumayɛ, ahoɔden a ɛgyina pintinn ne nsakrae a ɛba wɔ beae a ɛne wɔn ho wɔn ho di nkitaho no.
Asɛmmisa: So MFDC yi welding spatter fi hɔ?
A: Dabi MFDC ma programmable current ne timing control, nanso expulsion da so ara betumi aba sɛ welding nhyehyɛe, electrode ahoɔden, fit-up, cooling anaa electrode tebea no mfata a.
