Kodi nditani ngati pali mabowo kuwotcherera mu zitsulo kapangidwe processing?

Pokonza mapangidwe azitsulo, makamaka pazitsulo zowotcherera, pali zambiri zomwe ziyenera kuzindikiridwa ndi kutetezedwa pasadakhale, monga momwe angagwirire ndi pores zowotcherera, zomwe amakhulupirira kuti ndi vuto laminga lomwe limayambitsa ambiri opanga zitsulo.Dziwani nanu lotsatira.

Choyamba, tiyeni timvetsetse malamulo okhudzana ndi kuwotcherera pores muzitsulo zopangira zitsulo: ma welds a kalasi yoyamba ndi yachiwiri saloledwa kukhala ndi vuto la porosity;ma welds a kalasi yachitatu amaloledwa kukhala ndi ma diameter <0.1t ndi ≤3mm pa 50mm kutalika kwa ma welds.Pali mabowo awiri a mpweya;kusiyana kwa dzenje kuyenera kukhala ≥ ka 6 m'mimba mwake mwa dzenje.

Kenako, tiwonanso zifukwa zenizeni zopangira ma pores akuwotcherera pakukonza zitsulo:

1. Pali madontho a mafuta, madontho a dzimbiri, madontho a madzi ndi dothi (makamaka zizindikiro za utoto) mu groove ndi malo ake ozungulira, omwe ndi chimodzi mwa zifukwa za maonekedwe a pores mu weld;

2. Chophimba chamkuwa cha waya wowotcherera chimachotsedwa pang'ono, kotero kuti gawolo likhale la dzimbiri, ndipo msoko wowotcherera umatulutsanso pores;

3. The pambuyo Kutentha (deoxidation) wa workpiece wandiweyani si ikuchitika mu nthawi pambuyo kuwotcherera, kapena pambuyo Kutentha kutentha sikokwanira, kapena akugwira nthawi sikokwanira, zomwe zingayambitse pores otsalira mu weld;

4. Pali kugwirizana kwachindunji pakati pa pores pamwamba ndi kutentha kwa kuphika kwa zinthu zowotcherera, kuthamanga kwa kutentha kumathamanga kwambiri, ndipo nthawi yogwira sikwanira.

Mukamvetsetsa zomwe zimayambitsa kuwotcherera porosity pakukonza zitsulo, ndikofunikira kwambiri kuphunzira njira zake zodzitetezera:

1. Pores pamwamba ndi nambala yaing'ono ndi m'mimba mwake yaing'ono akhoza pansi ndi angular akupera gudumu, mpaka mbali imeneyi akhoza bwino kusintha ndi kuwotcherera lonse ndi bwino kusintha kwa zitsulo m'munsi;

2. The workpiece wandiweyani ayenera preheated pamaso kuwotcherera ndi kufika kutentha chofunika ndi specifications.Wokhuthala workpieces ayenera mosamalitsa kulamulira kutentha pakati njanji;

3. Zida zowotcherera ziyenera kuphikidwa ndikutenthedwa molingana ndi malamulo, ndipo zisakhale mumlengalenga kwa maola oposa 4 mutagwiritsidwa ntchito;

4. Samalani ndi malo owotcherera pakuwotcherera.kuwotcherera kuyenera kuyimitsidwa pamene chinyezi chachibale ndi chachikulu kuposa 90%;kuwotcherera pamanja arc kumachitika pamene liwiro la mphepo limaposa 8m / s, ndipo kuwotcherera kotetezedwa ndi mpweya kumachitika pamene liwiro la mphepo limaposa 2m/s.Kutentha kukakhala kochepera 0 ° C, chogwirira ntchito chiyenera kutenthedwa mpaka 20 ° C, ndipo chogwirira ntchito chomwe chiyenera kutenthedwa chiyenera kutenthedwa ndi 20 ° C panthawiyi.

5. Samalani magawo a ndondomeko yowotcherera ndikuwongolera luso lazitsulo.Mgolo wamagetsi otetezedwa ndi mpweya uyenera kuwotcherera ndi mpweya woponderezedwa pafupipafupi kuti muchotse litsiro.

Tsatanetsatane zimatsimikizira kupambana kapena kulephera, ndipo pali mwayi wambiri pamavuto pakuwotcherera, zomwe ndizofunikira kwambiri pakukonza zitsulo.
