IIMPAWU:

TQZ308ngundoqo we-nickel welding, ukucuthwa okuqinileyo kohlobo lwe-graphite yokwaleka intonga yentsimbi.Ingasetyenziswa AC kunye DC injongo ezimbini kwaye kulula ukusebenza.Xa i-welding, akuyimfuneko ukuba i-weldment iqale ukutshisa.Inokumelana nokuqhekeka okulungileyo kunye nokuqhubekeka.

IZIQINISEKISO:

1. Ngaphambi kwe-welding, ii-electrode kufuneka zibhakwe iyure enye kunye nobushushu obuyi-150±10℃ phambi kokusetyenziswa.
I-2 inokuphelisa uxinzelelo lwe-welding kwaye igweme i-crack ngokubethelela i-welding seam.
3. Ukuze kuncitshiswe izinto zokungcola kwisiseko sentsimbi yokungena kwi-weld, ububanzi obumxinwa obumhlophe band, ukuphucula ukumelana nokuqhekeka kunye neempawu zokucubungula, kufuneka kusetyenziswe ukuwelda okuncinci ngoku kwi-welding yentsimbi ebandayo.

Ukulungiswa kokuphazamiseka kweWelding:

Ukulungiswa koguquko kwimeko eshushu, ukulungiswa koomatshini kunye nokubethelwa kuthintelwe ngokungqongqo kuluhlu lweqondo lobushushu obuluhlaza okwesibhakabhaka (300℃~500℃) ukunqanda iintanda ezinqabileyo.

Nika ingqalelo kwezi mfuno zilandelayo xa idangatye litshiswa ekuhlaleni

Akukhuthazwa ukuphinda ukufudumala kwindawo efanayo ukuze ugweme utshintsho kwisakhiwo se-metallographic kunye neempawu zomatshini zetsimbi.

Musa ukubangela ukulungiswa okuphindaphindiweyo koxinzelelo kunye noxinzelelo kwindawo efanayo.

Kwiindawo ezidityanisiweyo eziqinileyo, ukunkcenkceshela kunye nokupholisa ngokukhawuleza akuvumelekanga ngokungqongqo.

Iinxalenye ze-welding ezifuna ukuhlanjululwa kufuneka zilungiswe ngaphambi kokuba zihlanjululwe ukuze kupheliswe uxinzelelo lwangaphakathi ngexesha lokucoca.Ngexesha lokufakwa kwe-annealing, iindawo ezidityanisiweyo kufuneka zibekwe ngokuthe gqolo ukwenzela ukuba zingakhubeki kwakhona.

Ilangatye lobushushu bokulungisa iqondo lobushushu linokuba yi-700℃~850℃ (fuchsia), kwaye akufanele lidlule kwi-900℃ (elibomvu eliqaqambileyo) kwintsimbi ephantsi ye-alloy structural.
