Ipayipi elishiselwe ipayipi lensimbi elakhiwe ikhoyili yensimbi ye-welding ibe umumo weshubhu. Ibonakala kakhulu ngezindleko eziphansi zokukhiqiza, ukusebenza kahle kokukhiqiza okuphezulu kanye nokuguquguquka okuqinile kokucubungula, futhi isetshenziswa kabanzi ekwakhiweni, kwe-petroleum, embonini yamakhemikhali, ekwenziweni kwemishini nakweminye imikhakha. Ipayipi elishiselwe linamandla amahle nokuqina. Ngokuthuthuka kobuchwepheshe, uhla lokusebenza kanye nokusetshenziswa kwamapayipi ashiselwe akhula njalo, futhi kancane kancane azivumelanisa nezidingo ezibanzi nezifunayo zohlelo lokusebenza.
