Li-valve le shaft Surfacing Welding Electrodes D507

LIKOPO:

E sebelisetsoa ho koala li-shafts le li-valve tsa tšepe ea carbon kapa alloy steel eo mocheso oa eona o ka holimo o ka tlase ho 450 ° C..

LITŠOANTŠISO:

D507 ke eleketrode e holim'a holim'a metsi e nang le coat e tlase ea hydrogen sodium.

Tšepe e ka holimo ke tšepe ea 1Cr13 semi ferrite e phahameng ea chromium.

Lera le thata le na le litšobotsi tsa ho tima moea, ka kakaretso ha le hloke kalafo ea mocheso,

'me ho thatafala ha eona ho tšoana,' me e ka boela ea e-ba annealing-softing ka mefuta e fapaneng ea 750 ° C -800 ° C.

Morero o habeli, ts'ebetso e ntle ea welding.E futhumetse ho 900-1000 ° C, e ka thatafatsoa hape ka mor'a hore moea o pholile kapa o tima oli.

Khokahano ea reverse ea DC e teng.
