Ibiranga ibikoresho bisanzwe by'icyuma [icyuma cya karuboni]

Gusudira hakoreshejwe laser birakwiriye mu gusudira ibikoresho bitandukanye. Ubucucike bw'imbaraga nyinshi za laser n'umuvuduko wo gusudira mwinshi bituma agace kasudiramo laser n'agace kagize ikibazo cy'ubushyuhe biba bike cyane. Imiterere ya shimi y'ubusudi ishobora guhindurwa hakurikijwe ibisabwa bitandukanye by'imiterere y'ubusudi, kandi imikorere myiza y'ubusudi ishobora kuboneka hakoreshejwe kugenzura imiterere y'ubusudi.

Icyuma cya karuboni

Icyuma gikozwe muri karuboni nke n'icyuma gikozwe muri aloyi nke bifite ubushobozi bwo gusudira neza, ariko iyo ukoresheje laser welding, ingano ya karuboni mu bikoresho (ingana na karuboni C) ntigomba kurenza 0.25%.

Ifishi yo kubara ingana na karuboni:

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

Ku bikoresho bifite agaciro ka karuboni karenze 0.3%, imiterere y’ubukonje bwo gusudira irazamuka. Ukurikije ko ubucucike runaka bw’ubucucike mu gishushanyo mbonera, bifasha kugabanya stress n’imiterere y’ubucucike mu gace kagizweho ingaruka n’ubushyuhe. Iyo ibikoresho bifite agaciro ka karuboni karenze 0.3% n’ibikoresho bifite agaciro ka karuboni karenze 0.3% bihujwe hamwe, ubucucike bw’ubucucike ni ingirakamaro mu kugabanya ihinduka rya martensite no kugabanya ivuka ry’ubucucike. Iyo agaciro ka karuboni k’ibikoresho karenze 0.3%, kugabanya umuvuduko wo kuzimya bishobora kandi kugabanya imiterere y’ubucucike.

Icyuma cya galvanised, kubera ko ubushyuhe bwa zinc (903℃) buri hasi cyane ugereranije n'aho icyuma gishonga (1535℃), imyuka ya zinc mu gihe cyo gusudira itera imyenge ikomeye muri weld, bityo biragoye gukoresha welding ya laser, cyane cyane welding inyuramo. Ubu hari igerageza ryo gushyiraho icyuho cya 0.1mm hagati y'ibikoresho byo hejuru n'ibyo hasi kugira ngo imyuka ya zinc ikure mu cyuho. Ariko biragoye gukoresha aho icyuho kiri mu musaruro nyawo.

Ingano ya sulfur na fosifore igira ingaruka ku gice cyo gusudira. Icyuma gifite ingano ya sulfur iri hejuru ya 0.04% cyangwa ingano ya fosifore iri hejuru ya 0.04% gishobora kwangirika mu gihe cyo gusudira hakoreshejwe laser.

Ubuso bw'icyuma cya karuboni kubera ubwinshi bwacyo bwa karuboni buri hejuru, byoroshye gukora imiyoboro yo gukomera no kwangirika muurwego rwa karuboni, ubusanzwe ntirukwiriye gukoreshwa mu gusudira hakoreshejwe laser.
