Kuwotcherera kwapang'onopang'ono ndiko kugwiritsa ntchito khungu kuti lipangitse kuti mphamvu zamakono zamakono zikhale pamwamba pa workpiece;Kuyandikira kwapafupi kumagwiritsidwa ntchito poyang'anira malo ndi mndandanda wa maulendo apamwamba omwe akuyenda panopa.Liwiro lamakono ndilothamanga kwambiri, limatha kutentha m'mphepete mwa mbale yachitsulo yoyandikana nayo mu nthawi yochepa kwambiri, kusungunula, ndikuzindikira kuti docking kupyolera mu extrusion aliyense ali ndi ubwino wake, komanso ali ndi zofooka zake.Kaŵirikaŵiri pamafunika kupenda zosankha zenizeni malinga ndi mikhalidwe inayake.
Njira yopangira Electric Resistance Welding (RW) Pipe ndi motere:
Tsegulani mbale zofufuza → Kuwongola mphero → kudula kupanga → Kudula matako → Kuyang'ana m'maso → Kuyang'ana mwaukadaulo → Kuwunika kwa X-ray → Mayeso opanikizika → Kuwotchera kwathyathyathya → Kuyendera komaliza
Chitoliro chopanda kanthu kapena zokutira zakuda / varnish (zosinthidwa);
m'mitolo kapena momasuka;
Zonsezi zimathera ndi otetezera mapeto;
Mapeto osavuta, malekezero a bevel (2"ndi pamwamba ndi ma bevel malekezero, digiri: 30 ~ 35 °), ulusi ndi kulumikizana;
Kuyika chizindikiro.
