Lefatšeng la tlhahiso ea liindasteri, haholo-holo lekaleng la matla, boleng ba li-welds tlhahiso ea lipeipi bo bohlokoa. Sena ke 'nete ka ho khetheha bakeng sa liphaephe tsa khase, moo botšepehi ba weld bo ka bolelang phapang pakeng tsa polokeho le tlokotsi. Fekthering ea rona e Cangzhou, Profinseng ea Hebei, re utloisisa karolo ea bohlokoa eo boleng ba weld bo e bapalang ho netefatsa ho ts'epahala le polokeho ea lihlahisoa tsa rona. Khamphani ea rona e thehiloe ka 1993 mme e se e holile ho akaretsa sebaka sa lisekoere-mithara tse 350,000, thepa eohle ea RMB limilione tse 680, le basebetsi ba inehetseng ba 680.
E 'ngoe ea lintlha tsa bohlokoa tse lokelang ho nahanoa ha liphaephe tsa khase ea tlhaho li chesoa ke mofuta oa theknoloji ea welding e sebelisoang. Bakeng saspiral welded pipe, mokhoa o tloaelehileng haholo ke mokhoa oa submerged arc welding (SAW). Mokhoa ona o ratoa ka lebaka la bokhoni ba ona ba ho hlahisa li-welds tse matla, tse tšoarellang, tsa boleng bo holimo. Ts'ebetso ea welding ea arc e ka tlas'a metsi e kenyelletsa ho thehoa ha arc pakeng tsa eleketrode e feptjoang ka mokhoa o tsoelang pele le sesebelisoa sa mosebetsi, se qoelisoang ka tlas'a lera la granular flux. Sena ha se sireletse feela weld ho tloha tšilafalo, empa hape se ntlafatsa boleng ba weld ka ho fana ka arc e tsitsitseng le ho fokotsa spatter.
Bohlokoa baphaepheboleng ba tjheseletsa bo ke ke ba feteletswa. Ho tsamaisa khase ea tlhaho, ho hloleha hofe kapa hofe ho ka lebisa litlamorao tse mpe, ho kenyelletsa ho lutla, ho phatloha le tšenyo ea tikoloho. Ka hona, ho netefatsa hore lits'ebetso tsa rona tsa welding li fihlela maemo a holimo ke ntho e tlang pele. Boitlamo ba rona ba boleng bo qala ka khetho ea lisebelisoa tse tala 'me bo tsoela pele ho pholletsa le mohato o mong le o mong oa ts'ebetso ea tlhahiso, ho kenyelletsa le tlhahlobo e matla le tlhahlobo ea li-welds.
Setsing sa rona sa Cangzhou, re sebelisa theknoloji e tsoetseng pele le litsebi tse nang le boiphihlelo ho netefatsa hore ts'ebetso ea rona ea ho tjheseletsa ka tlas'a metsi arc e hlahisa litholoana tse nepahetseng. Sehlopha sa rona se koetliselitsoe ho beha leihlo le ho laola liparamente tsa welding ka hloko, ho netefatsa hore weld e 'ngoe le e 'ngoe e fihlela litlhoko tse tiileng tse laetsoeng ke maemo a indasteri. Tlhokomelo ena ea lintlha ha e ntlafatse feela sebopeho sa sebopeho sa liphaephe tsa rona tsa khase, empa hape e etsa hore bareki ba rona ba tšepehe, ba itšetlehileng ka lihlahisoa tsa rona bakeng sa lipalangoang tse sireletsehileng le tse sebetsang hantle tsa matla.
Ho feta moo, boleng ba weld pipeline bo ama ka kotloloho ts'ebetso le bophelo ba lipeipi. Boleng bo phahamengtube weldfokotsa monyetla oa mathata a tlhokomelo le ho lelefatsa bophelo ba lipeipi, qetellong ho boloka litšenyehelo bakeng sa bareki ba rona.
