I-AWS A5.23: I-ECF3 Submerged Arc Welding Wire Arc Cored Wires Isithombe Esifakiwe

AWS A5.23: ECF3 Submerged Arc Welding Wire Arc Cored Wires Low-Alloy Steel

Incazelo emfushane:

I-AWS A5.23: I-ECF3 Submerged Arc Cored Wires Low-Alloy Steel, eChina

Thumela i-imeyili kithi

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

ISIKHATHI:

I-AWS A5.23: I-ECF3 Izintambo Ezigxilile ze-Arc Cored Insimbi Yensimbi Ephansi

INCAZELO:

I-AWS A5.23: I-ECF3 iyingxube ye-electrode yocingo ene-alloy ene-alloy ephansi yokushisela i-arc engaphansi ekusetshenzisweni kwamandla aphezulu.Futhi ihlangana ne-AWS A5.23 chemistry F3, futhi yakhelwe amazinga wamandla aqinile angaphezu kuka-100 ksi.

IZICI NEZINZUZO:

Izintambo ezinezimbombo zensimbi zinganikeza amanani athuthukisiwe okufakwa uma kuqhathaniswa nezintambo eziqinile ngama-ampeges aqatha

Izintambo ezinezintambo zensimbi zinikeza amaphrofayili okungena abanzi uma kuqhathaniswa nezintambo eziqinile kumapharamitha wokushisela aqhathaniswayo.

Izidingo zokwakheka kwamakhemikhali we-Weld zifana nalezo zezintambo eziqinile ze-EF3

I-Weld deposit chemical composition iqukethe ngaphansi kwe-nickel engu-1%.

Ukuqina komthelela omuhle kakhulu wezinga lokushisa eliphansi kuzo zombili izimo ezishiselwe kanye nezisusa ingcindezi

Inikeza amandla okwandisa isivinini sokuhamba ukuze kuthuthukiswe umkhiqizo

Isiza ukuvimbela ukushiswa lapho ishisela kumaza aphezulu ezimpahleni zokudlula kanye nezinto ezisetshenziswayo ezincanyana.

Ifaneleka njengenye indlela yokukhiqiza okuphezulu ezinhlelweni eziningi ezisebenzisa i-EF3 intambo eqinile

Ifanele ukusetshenziswa kwegesi emuncu lapho ukugqwala kwe-stress corrosion ngenxa ye-hydrogen-sulfide kuwukukhathazeka.

Isiza ukunciphisa ubungozi bokuqhekeka ezinhlelweni ezibucayi nasezindaweni zesevisi ezinokhahlo

IZImboni:

Ukwenziwa kwesakhiwo, uwoyela negesi, ukuphehla ugesi, okokusebenza esindayo

UHLOBO LWENGAMBO:

I-Metal-powder, i-metal-coreed wire

AMANJE:

I-HN-590, SWX 120, SWX 150

OKWENZIWA:

irect Current Electrode Positive (DCEP), Direct Current Electrode Negative (DCEN), Alternating Current (AC)

ISITOREJI:

Umkhiqizo kufanele ugcinwe endaweni eyomile, evalekile, kanye nasephaketheni lawo langempela

imvaba (1)

Ukugcina inqubo efanele yokushisela - okuhlanganisa ukushisa kwangaphambi kwesikhathi kanye ne-interpass - kungase kubaluleke kakhulu kuye ngohlobo nokujiya kwensimbi eshiselwayo.

Amapharamitha ahlinzekelwe izinjongo zolwazi kuphela.Wonke amanani ayalinganiselwa.I-voltage elungile ingase ihluke (imvamisa engu-±2 volts) kuye ngokukhetha ukuguquguquka, ukujiya kwempahla, ukwakheka okuhlangene, nokunye okuhlukile okuqondene nohlelo lokusebenza.

Ngokufanayo, izinga langempela lokubeka lingahluka kuye ngokukhetha ukuguquguquka kanye nethiphu yokuxhumana ukuya ebangeni lokusebenza.
