Resistance weldingnzira yakagadziridzwa nekukurumidza kubva payakavambwa mukupera kwezana ramakore re19, kunyanya nekukwira kwekugadzirwa kwakawanda kweindasitiri yemotokari nemamwe mabhizinesi, iko kuri kuwedzera kupararira kwekushandisa.Zvinoenderana nenhamba, iyo yazvino yekudzivirira welding nzira yakaverengera inosvika 1/4 yebasa rese rewelding.Iyo yakaoma zvikamu zvakagadzirira, imwe yegungano rekugadzira maitiro.
Chekutanga, kupikisa welding ndiko kudiwa kwekumanikidza pasi kuti apedze kukwenenzverwa, saka kana iri kubva kune solder majoini maumbirwo ekugadzira kana kubva kune imwe welding inosunga poindi iyo welding iri nyore, nepo kuramba welding ine yakakosha zvakanyanya welding zvinhu hunhu, izvo welded havadi kuita ebetsero, havafaniriwo kushandisa waya netsvimbo nokuda nomoto filler kuita izvi, nokudaro kuponesa zvikuru matambudziko akawanda mutengo, asiwo zvikuru kuwedzera kubudirira.
Chechipiri, resistance welding ibasa riri nyore iro, pasi pekushanda kuri nyore panguva imwe chete, munzvimbo yewelding iyo inewo mukana wakawanda, haugone kuita utsi.
Kuenzaniswa neyakajairwa welding tekinoroji, resistance welding ine zvinotevera zvakakosha:
1) kupisa kwakanyanya, nguva yekupisa ipfupi, diki welding deformation.
2) metallurgical process iri nyore, uye kazhinji haidi kuzadza zvinhu uye solvent haikodzeri kuchengetedza gasi.
3) kukwanisa kujairana nemhando dzakawanda dzakafanana uye dzakasiyana simbi welding, kusanganisira welding ye plated steel plate.
4) Maitiro acho ari nyore, ari nyore kushandisa mechanization uye otomatiki, pre-basa haidi kudzidziswa kwenguva refu kwevanopisa.
5) welded nemhando yepamusoro uye mutengo wakaderera.
6) nzvimbo yekushanda iri nani uye kusvibiswa.
