Ịcha odo odo nke Weld Spots na Welding Nut Projection Welding na Mmezi?

Na nut projection ịgbado ọkụ, ọ bụghị ihe ọhụrụ na weld tụrụ na-egosipụta a-acha odo odo mgbe usoro ịgbado ọkụ. Edemede a na-ekwu maka ihe kpatara ihe na-acha odo odo ma na-enye ihe ngwọta iji belata okwu a, na-ahụ na mmepụta nke welds dị elu.

Ihe na-akpata agba odo:

1. Oxidation: Acha odo odo nwere ike ime n'ihi oxidation nke weld ntụpọ n'oge ịgbado ọkụ usoro. Ihe ndị dị ka mkpuchi mkpuchi gas na-ezughị oke ma ọ bụ nhicha na-adịghị mma nke elu workpiece nwere ike ime ka ikuku oxygen dịkwuo elu, na-ebute oxidation.
2. Mmetọ: Ọnụnọ nke mmetọ, dị ka mmanụ, griiz, ma ọ bụ mkpuchi elu na workpiece ma ọ bụ aku, nwere ike itinye aka na agba odo nke ntụpọ weld. Ihe ndị a na-emerụ emerụ nwere ike imebi okpomọkụ n'oge usoro ịgbado ọkụ, na-eduga n'ịgbanwe agba.
3. Oke okpomoku: Ntinye oke ọkụ ma ọ bụ ogologo oge ịgbado ọkụ nwekwara ike ime ka ntụpọ weld gbanwee agba. Oke ikpo ọkụ nwere ike ime ka e guzobe ogige intermetallic ma ọ bụ mgbanwe na microstructure, na-eduga na ọdịdị na-acha odo odo.

Ihe ngwọta maka ịcha edo edo:

1. Nhicha nke ọma: hichaa nke ọma workpiece na akị na-ebupụta tupu ịgbado ọkụ iji wepụ ihe ọ bụla na-emerụ emerụ. Jiri ụzọ ihicha kwesịrị ekwesị, dị ka ịkwatu ma ọ bụ ihicha ihe mgbaze, iji hụ na elu dị ọcha na enweghị mmetọ.
2. Gas nchekwa zuru oke: Gbaa mbọ hụ na mkpuchi gas zuru oke n'oge usoro ịgbado ọkụ iji belata ikpughe ikuku oxygen. Enwere ike nweta nke a site n'ịgbanwe ọnụego ikuku gas, na-ebuli ọnọdụ nozzle, ma ọ bụ iji iko gas ma ọ bụ ihe mkpuchi iji kwalite mkpuchi gas.
3. Hazie ihe ịgbado ọkụ: Gbanwee paramita ịgbado ọkụ, dị ka ugbu a, voltaji, na oge ịgbado ọkụ, iji nweta nguzozi kachasị mma n'etiti ntinye ọkụ na ịdị mma weld. Zere oke okpomọkụ nke nwere ike iduga ngbanwe site n'ịkwalite ihe ndị dabere na ụdị ihe na ọkpụrụkpụ.
4. Nyochaa ndakọrịta ihe: Nyochaa ndakọrịta n'etiti ihe arụrụ arụ, ihe nut, na mkpuchi elu ọ bụla. Ihe na-adịghị mma ma ọ bụ mkpuchi nwere ike ịnweta mmeghachi omume na-adịghị mma n'oge ịgbado ọkụ, na-eduga n'ịgbanwe agba. Họrọ ihe dakọtara ma ọ bụ tụlee iwepụ mkpuchi na-ekwekọghị tupu ịgbado ọkụ.
5. Nchacha Post-Weld: Mgbe ịmechara usoro ịgbado ọkụ ahụ, rụchaa ihicha weld iji wepụ ihe ọ bụla ma ọ bụ spatter nwere ike itinye aka na ngbanwe. Jiri ụzọ nhicha kwesịrị ekwesị dabere na ihe achọrọ ngwa ngwa.

Enwere ike ịpụta odo odo nke ntụpọ weld na welding nut projection site na oxidation, mmetọ, ma ọ bụ oke okpomọkụ. Site n'imejuputa usoro ihicha nke ọma, hụ na mkpuchi mkpuchi gas zuru oke, na-ebuli paramita ịgbado ọkụ, na-enyocha ndakọrịta ihe, na ime nhicha mgbe weld, ndị na-emepụta nwere ike belata okwu nke ịcha edo nke ọma ma nweta welds dị elu. Nleba anya nke usoro ịgbado ọkụ mgbe niile na ịrapagidesi ike na omume kachasị mma ga-enyere aka hụ na ọdịdị weld na-agbanwe agbanwe yana ogo ngwaahịa niile.
