Chitsulo cha ASTM A513ndi chitoliro cha kaboni ndi alloy chitsulo ndi chubu chopangidwa kuchokera ku chitsulo chotenthedwa kapena chozizira ngati zinthu zopangira ndi njira yolimbana ndi welding (ERW), chomwe chimagwiritsidwa ntchito kwambiri m'mitundu yonse ya makina.
Mtundu 1 ukhoza kugawidwa m'magulu 1a ndi 1b.
Mtundu 1a (AWHR): "yolumikizidwa ngati welded" kuchokera ku chitsulo chotenthedwa (chokhala ndi sikelo ya mphero).
Mtundu uwu wa chitoliro umalumikizidwa mwachindunji kuchokera ku chitsulo chozunguliridwa ndi moto ndi iron oxide (chiwerengero cha mphero) chomwe chimapangidwa pozungulira. Mtundu uwu wa chitoliro nthawi zambiri umagwiritsidwa ntchito m'malo omwe kulimba kwa pamwamba sikofunikira chifukwa pamwamba pake pali chiŵerengero cha mphero.
Mtundu 1b (AWPO): "yolumikizidwa ngati welded" kuchokera ku chitsulo choviikidwa ndi mafuta chotenthedwa ndi choviikidwa ndi moto (chiyeso cha mphero chachotsedwa).
Mtundu uwu wa chitoliro umapangidwa ndi chitsulo chotenthedwa chomwe chapakidwa mafuta ndipo chimadziwika ndi kuchotsa sikelo ya mphero. Kupaka mafuta sikuti kumachotsa kukhuthala kwa pamwamba kokha komanso kumapereka chitetezo cha dzimbiri ndi mafuta panthawi yokonza, zomwe zimapangitsa kuti chitolirochi chikhale choyenera kugwiritsidwa ntchito zomwe zimafuna malo oyera kapena zinthu zogwirira ntchito zolimba pang'ono.

Yotenthedwa
Pakupanga, chitsulo chotenthedwa ndi moto chimayatsidwa poyamba kutentha kwambiri, zomwe zimapangitsa kuti chitsulocho chizunguliridwe ngati pulasitiki, zomwe zimapangitsa kuti zikhale zosavuta kusintha mawonekedwe ndi kukula kwa chitsulocho.
