ERW (Electric Resistance Welding) chitoliro chachitsuloimatchedwa ERW chitoliro kapena HF welded chitoliro, ili ndi zabwino zambiri monga izi:

1) Kupanga kwapamwamba, mtengo wotsika, mtengo wake ndi wa UOE wowongoka msoko womira arc welded zitsulo, 85%;

2) kulondola kwapamwamba kwambiri, kuzungulira kwake (Roundenss) ndikwapamwamba kuposa chitoliro chowotcherera chozungulira, mnzakeyo amatha kupulumutsa maola ambiri m'munda;

3) yosalala pamwamba, maonekedwe okongola, amene amathandiza kuti ❖ kuyanika mkati ndi kunja TACHIMATA.M'mbuyomu, kudalirika kosadalirika kwa ma welds a ERW, chitoliro pakhala pali ngozi zambiri, motero kuchepetsa kugwiritsa ntchito chitoliro cha ERW.Posachedwapa, Zhejiang Jinzhou Gulu padera kwambiri, mwa khama olowa ofufuza ndi wopanga chitoliro, zinthu zasintha kwambiri ERW zitsulo chitoliro kuwotcherera khalidwe akhoza kufananizidwa ndi LSAW ofanana.

Njira ya ERW chitoliro kuchita izi:

1) kuwongolera kulowetsamo kutentha munjira, zinthu zambiri zimakhudza kuyika kwa kutentha, choyamba ndi convergence angle (Convergency Angle).Zotsatira zake zidawonetsa kuti, pakakhala zinthu zina mosadukiza, mbali yolumikizira ndi yayikulu kwambiri kuti ipangitse kuwotcherera kozizira, mbali ya convergence ndi yaying'ono kwambiri imapangitsa kuyaka kwambiri.Chinthu chinanso chomwe chimakhudza chitoliro chothandizira chotenthetsera pa liwiro lakutsogolo la mzere wopanga.Zotsatira zikuwonetsa kuti pazinthu zina nthawi zonse, liwiro limakhala lothamanga kwambiri lingayambitse kuwotcherera kozizira, pang'onopang'ono, kungayambitse kuwotcha.

2) kukulitsa mzere basi kudziwika chubu fakitale mu Jinzhou, pofuna kuonetsetsa khalidwe la ERW chitoliro, zina Mipikisano njira cholakwa kuzindikira mu luso chitoliro.Unwinding Mzere mbali zonse za akupanga kuyezetsa, Eddy panopa anayendera pambuyo akamaliza kuwotcherera.Kuphatikiza apo, kuyang'ana kowoneka bwino, ndi zitsanzo za mayeso a flattening ndi mayeso ena amakanika.
