Ma mesh amphamvu kwambiri: kusankha zinthu ndi kuwotcherera

 Monga chinthu chofunikira kwambiri choteteza komanso chothandizira pantchito yomanga, ulimi, mafakitale, ndi zina zambiri, magwiridwe antchito amphamvu kwambiri amakomera amatengera kufananiza pakati pa kusankha kwazinthu ndi njira yowotcherera.

Kusankha zinthu ndizo maziko. Ma mesh apamwamba kwambiri amphamvu kwambiri amagwiritsa ntchito mawaya achitsulo otsika mpweya, waya wazitsulo kapena waya wachitsulo chosapanga dzimbiri ngati zida. Waya wachitsulo wochepa wa carbon ndi wotsika mtengo ndipo uli ndi ntchito yabwino yokonza, yomwe ili yoyenera pazochitika zachitetezo wamba; waya wazitsulo wopangidwa ndi zitsulo amathandizidwa ndi kuviika kotentha kapena galvanizing electro-galvanizing kuti apititse patsogolo kukana kwa dzimbiri, komwe kuli koyenera kumadera a chinyezi kapena kunja; ndi waya wazitsulo zosapanga dzimbiri (monga 304, 316 zitsanzo) ali ndi kukana kwa dzimbiri komanso kukana kutentha kwambiri, ndipo nthawi zambiri amagwiritsidwa ntchito m'malo ovuta kwambiri monga makampani opanga mankhwala ndi nyanja. Posankha zipangizo, m'pofunika kuganizira mozama zofunikira zonyamula katundu, kuwonongeka kwa chilengedwe ndi bajeti ya ndalama zomwe zimagwiritsidwa ntchito.

Njira yowotcherera ndiyo chinsinsi. Pachimake champhamvu kwambirimauna weldedyagona mu mphamvu ya weld point, ndipo zida zowotcherera zokha zimafunikira kuti zitsimikizire kuti nsonga ya weld ndi yofanana komanso yolimba. Resistance welding technology imasungunula zitsulo pa kutentha kwakukulu kudzera mumagetsi amakono kuti apange ma welds amphamvu kwambiri, omwe ali oyenera kupanga misa; pamene kuwotcherera kwa gasi kapena kuwotcherera kwa laser kumatha kupititsa patsogolo kulondola kwa ma welds kuti akwaniritse zofunikira zapadera. Kuphatikiza apo, njira yochizira kutentha pambuyo pakuwotcherera (monga annealing) imatha kuthetsa kupsinjika kwamkati, kupewa kusokoneza zinthu, ndikuwonjezera moyo wautumiki.

Kukhathamiritsa kolumikizidwa kwa zida ndi njira ndiye maziko opangira ma mesh amphamvu kwambiri. Pokhapokha pofananiza bwino zinthu zakuthupi ndi zowotcherera zomwe zingapangitse kuti pakhale malire pakati pa ntchito ndi mtengo, kupereka mayankho odalirika amakampani osiyanasiyana.
