Chitoliro chachitsulo chozungulira chozungulira cha arc chili ndi makulidwe a khoma lofanana, chimawoneka bwino, chimakhala chokhazikika, komanso chokhazikika. The ozungulira msoko kumizidwa arc welded chitsulo chitoliro ali wosafanana makulidwe khoma ndi kupsyinjika wosiyana pa chitoliro zitsulo. Mbali zowonda za chitoliro chachitsulo zidzathyoka mosavuta. Kuchuluka kwa khoma la chitoliro chachitsulo ndi chodabwitsa chomwe chimapezeka mosavuta pakusintha kwa mipope yachitsulo. Kuchuluka kwa khoma la mipope yachitsulo kumawonekera makamaka mu makulidwe a khoma lozungulira lozungulira, makulidwe a khoma losafanana, komanso makulidwe olimba kapena ocheperako pamutu ndi mchira. Zambiri ndi:

1: Makulidwe a khoma losafanana pamutu ndi mchira
Zomwe zimayambitsa: 1) Kumapeto kwa kutsogolo kwa msoko wozungulira woviikidwa m'madzi arc welded zitsulo chitoliro chopanda kanthu chimadulidwa ndi kupendekera ndi kupindika kwakukulu, ndipo dzenje lapakati la chitoliro lopanda kanthu silili lolondola, lomwe lingathe kupanga mutu wa chitoliro chopindika mosavuta. makulidwe a khoma losiyana; 2) Coefficient elongation ndi yayikulu kwambiri pobowoleza, ndi roller Kuthamanga kozungulira ndikokwera kwambiri ndipo kugubuduza kumakhala kosakhazikika; 3) Kuponyedwa kwachitsulo kosasunthika ndi makina okhomerera kungayambitse mosavuta makulidwe a khoma kumapeto kwa chubu cha capillary.

2: Osafanana ozungulira khoma makulidwe
Zomwe zimayambitsa ndi izi: 1) makulidwe a khoma osagwirizana chifukwa cha zosintha monga kugubuduza kolakwika pakati pa makina oboola, ngodya zofananira za odzigudubuza awiri, kapena kuchuluka kwapang'onopang'ono kutsogolo, komwe kumagawika mozungulira mozungulira kutalika konse kwa tapered. chitoliro chachitsulo; 2) Makulidwe osagwirizana a khoma chifukwa cha kutsegula msanga kwa chodzigudubuza chapakati, kusintha kosayenera kwa chodzigudubuza chapakati, komanso kugwedezeka kwa ejector panthawi yogubuduza nthawi zambiri kumagawidwa mozungulira mozungulira kutalika konse kwa chitoliro chachitsulo cha tapered.
