Inyaya dzipi dzekuchengeteka dzatinofanira kufunga nezvadzo kana tichikuchidzira?Dzimwe nguva kuregeredza uku kunotungamira tsaona, saka tinofanira kuedza nepatinogona napo kuti njodzi dziitike pamberi pebud ~ Nekuda kwenzvimbo dzebasa dzakasiyana kwazvo, uye magetsi, chiedza, kupisa uye mirazvo yakavhurika inogadzirwa mubasa, kune njodzi dzakasiyana siyana. mukushanda kwewelding.
1, Zviri nyore kukonzera tsaona dzemagetsi.
Mukugadzirisa, nokuti mawelders anowanzoda kushandura electrode yakavharwa uye kugadzirisa ikozvino welding, inofanirwa kubata zvakananga electrodes uye polar plates panguva yekushanda, uye magetsi emagetsi anowanzo 220V / 380V.Kana iyo magetsi ekudzivirira kuchengetedza mudziyo yakanganisa, zvinyorwa zvekuchengetedza basa hazvina kukodzera, uye mushandisi anoshanda zvisiri pamutemo, zvinogona kukonzera tsaona yemagetsi.Muzviitiko zvekupinza mumidziyo yesimbi, mapaipi kana nzvimbo dzakanyorova, Njodzi dzekuvhunduka kwemagetsi dzakakura.

2, Zviri nyore kukonzera moto uye kuputika tsaona.
Nekuti arc yemagetsi kana murazvo wakavhurika uchagadzirwa muwelding process, zviri nyore kukonzera moto kana uchishanda munzvimbo dzine zvinhu zvinopisa.Kunyanya munzvimbo dzinopfuta uye dzinoputika (kusanganisira makomba, migero, madhiri, nezvimwewo), zvine njodzi zvakanyanya kana uchisungirira pamidziyo, shongwe, matangi uye mapaipi akachengeta midhiya inopfuta uye inoputika.

3, Zviri nyore kukonzera electro-optic ophthalmia.
Nekuda kwechiedza chakasimba chinooneka uye huwandu hukuru hweasingaoneki ultraviolet mwaranzi inogadzirwa panguva yewelding, ine simba rinokurudzira uye rinokuvadza pameso evanhu.Kugara kwenguva refu kwakananga kunokonzera kurwadziwa kwemaziso, photophobia, misodzi, kutya mhepo, nezvimwewo, uye nyore nyore kutungamirira mukuzvimba kwe conjunctiva uye cornea (inowanzozivikanwa se electro-optic ophthalmia).
Iyo arc mwenje inogadzirwa muwelding ine mwenje mwenje ine infrared mwaranzi, ultraviolet mwaranzi uye inooneka mwenje, uye ine mwaranzi mhedzisiro pamuviri wemunhu.Iyo ine basa reiyo infrared radiation, iyo inotungamira nyore kune heatstroke kana welding munzvimbo yakanyanya tembiricha.Iine photochemical action ye ultraviolet rays, iyo inokuvadza kune ganda revanhu, uye panguva imwechete, kuratidzwa kwenguva refu kune ganda rakasvibiswa kuchaitawo kuti ganda rive rakachena.

4, Zviri nyore kukonzera kudonha kubva pakakwirira.
Sezvinodiwa nebasa rekuvaka, mawelder anowanzo kukwira kumusoro kuti ashande.Kana zviyero zvekudzivirira kudonha kubva pakakwirira zvisina kukwana, scaffolding haina kumira uye inoshandiswa pasina kugamuchirwa.Tora matanho ekuzviparadzanisa nevamwe kudzivirira zvinhu kubva pakurovera mukuchinjika;Welders havazivi nezvekuchengetedzwa kwekuchengetedzwa kwevanhu, uye usapfeke helmete yekudzivirira kana bhanhire rekuchengetedza paunenge uchikwira.Muchiitiko chekufamba kusina hanya, kukanganisa kwezvinhu zvisingatarisirwi nezvimwe zvikonzero, zvinogona kukonzera njodzi dzinodonha.

5, Magetsi emagetsi anowanzo kuita muchetura uye kudzipwa kazhinji anofanirwa kupinda munzvimbo dzakavharwa kana semi-akavharwa senge midziyo yesimbi, midziyo, mapaipi, shongwe uye matangi ekuchengetera simbi.Kana midhiya ine chepfu uye inokuvadza uye magasi anert akachengetwa, kutakurwa kana kubudiswa, kana basa rekushanda risina kunaka, matanho ekudzivirira haapo, izvo zvinozoita kuti zvive nyore kukonzera chepfu kana hypoxia uye kuvharwa kwevashandi.Ichi chiitiko chinowanzoitika mukunatsa mafuta. , indasitiri yemakemikari uye mamwe mabhizinesi.
