Mokhoa oa ho Welding ka Pipe

Tlas'a phala e cheselitsoeng ho tloha ka holim'a arc, ho tloha holimo ho ea tlase, mokhoa oa ho tjheseletsa maemo ohle, mokhoa oa ho tjheseletsa lebelo, ponahalo ea weld, boleng bo botle ba ho tjheseletsa, o ka boloka lisebelisoa tsa ho tjheseletsa, ho fokotsa matla a mosebetsi, e leng SMAW e tloaelehileng e ka khonang. e se ke ea bapisoa, 'me hona joale e sebelisoa haholo ho tjheseletsa liphaephe tse telele tsa sebaka se selelele sebakeng sohle sa matla kahong ea li-tubes tse nyenyane tse nang le bophara ba bophara bo tšesaane li nang le boleng bo itseng ba papatso.

 

Tlas'a tjheseletsa hangata khetha loketseng hona joale tjheseletsa, eleketrode angle le lebelo tjheseletsa, ho toba ka hula fatše kapa hatella arcing swing hanyenyane ho qeta tjheseletsa. Tloaelehileng eleketrode le tšekamelo ea rothele rothele tšepe e qhibilihisitsoeng le slag tlas'a potso, 'me tshebediso ya phaephe e inehetseng ho li-electrode tjheseletsa, tjheseletsa specifications tieo qobella, o ka rarolla mathata ana. Cellulose mofuta eleketrode tjheseletsa slag tlase, arc matla, ho satalla ka ho lekaneng ho thibela ho qhibiliha slag le rothele fatše le phunyeletse arc khōlō, haholo-holo bakeng sa lijana tse teteaneng le marako a tšepe phala e otla ka tlaase, o ka felisa ts'ebetso ea kharafu ea motso, kahoo e ntlafatsa mosebetsi. ho sebetsa hantle, ho ntlafatsa maemo a ts'ebetso, empa ka lebaka la litaba tsa eona tse phahameng tsa haedrojene tsa weld, kahoo bakeng sa tjheseletsa ea phala ea lapeng e nang le khatello e phahameng e sebelisoang hona joale e sebelisoang ka bongata ba selulose electrode backing plus low hydrogen electrode and filler cap surface welding.

 

Sehlopha se nepahetseng sa li-tubes le tack welding ke ho netefatsa boleng ba welding, mokokotlo oa weld e ntle ke ntlha ea bohlokoa. Tack welding seam ke karolo ea mokhoa o hlophisitsoeng, ha o hloke feela ho etsa welding lehlakoreng, empa hape le ho netefatsa boleng ba welding. Bolelele ba tjheseletsa bo bolelele ba 20mm, botenya bo ka bang 3mm, matsoapo a bonolo mahlakoreng ka bobeli a tjheseletsa a lokela ho siloa ka sebopeho, e le hore ho be bonolo ho kopanya.
Haufi le electrode ea ho tjheseletsa ho bohlokoa haholo ho sebelisa angle e nepahetseng. Ho tšehetsa weld, ho tlatsa le capping rod angle e hlile e tšoana, empa bolelele ba arc le lipalangoang tsa mofuta o fapaneng. Haufi le weld, weld e laoloa ke bolelele le bophara ba mefuta e meholo ea lipalangoang tsa arc, arc le arc e haufi le sebaka se fosahetseng se lokelang ho buleha.
