Hunhu hweWelding hweCommon Metal Materials [Carbon Steel]

Kupinza neLaser kwakakodzera pakupinza zvinhu zvakasiyana-siyana. Simba rakawanda reLaser uye kumhanya kwakawanda kwekubatanidza kunoita kuti nzvimbo inopinza nekupisa ive diki. Makemikari eweld anogona kugadziriswa zvichienderana nezvinodiwa zvechimiro cheweld, uye kushanda kwakanakisa kweweld kunogona kuwanikwa nekudzora mamiriro ekubatanidza.

Simbi yekabhoni

Simbi ine kabhoni shoma nesimbi ine alloy shoma zvine kugona kwakanaka kwe weld, asi kana uchishandisa laser welding, huwandu hwekabhoni muchinhu chacho (kabhoni yakaenzana neC) hahufanirwe kupfuura 0.25%.

Fomura yekuverenga yeyakaenzana nekabhoni:

C=C%+Mn/6%+Ni/15%+Cr/13%+Cu/13%+Mo/4%

Kune zvinhu zvine kabhoni yakaenzana nekabhoni inopfuura 0.3%, maitiro ekucheka kwechando achawedzera. Tichifunga nezvekuti weld iri muchimiro chayo, inobatsira kuderedza kushushikana kwasara uye maitiro ekupwanya munzvimbo inopwanya uye ine kupisa. Kana zvinhu zvine kabhoni yakaenzana nekabhoni inopfuura 0.3% uye zvinhu zvine kabhoni yakaenzana nekabhoni zvikasungirirwa pamwe chete, bias weld inobatsira kudzikamisa shanduko yemartensite uye kuderedza kugadzirwa kwemakumbo. Kana kabhoni yakaenzana nekabhoni inopfuura 0.3%, kuderedza kumhanya kwekudzima kunogonawo kuderedza maitiro ekupwanya.

Simbi yakagayiwa, nekuti tembiricha yekupwanya zinc (903℃) yakaderera zvikuru pane inonyunguduka yesimbi (1535℃), kupwanya zinc panguva yekuwelding kunokonzera maburi akakomba muweld, saka zvakaoma kushandisa laser welding, kunyanya kupinda muwelding. Iye zvino pane kuyedzwa kwekuisa mukaha we 0.1mm pakati pezvinhu zvepamusoro nepazasi kuti kuburitse mhute yezinc kubva mumukaha. Asi zvakaoma kushandisa nzvimbo yekubuda mukugadzirwa chaiko.

Kuwanda kwesarufa nephosphorus kune simba guru pakuputika kwesimbi. Simbi ine sarufa yakawanda kupfuura 0.04% kana phosphorus yakawanda kupfuura 0.04% inogona kutsemuka panguva yekucheka nelaser.

Pamusoro pesimbi yekabhoni nekuda kwehuwandu hwekabhoni pamusoro payo hwakakwira, zviri nyore kugadzira mitswe yakaomeswa uye mitswe mukabhoni layer, kazhinji haikodzeri kusungirirwa ne laser.
