Nheyo dzekutanga dzekusarudzwa kwekushandisa welding

Funga nezvezvinhu zvemuviri, mechanical properties uye makemikari ekugadzirwa kwezvinhu weld

1. Structural steel welding, kazhinji funga nheyo yesimba rakaenzana, sarudza kusangana nezvinodiwa zvema mechanical properties yejoint welding material.

2. Kune yakaderera kabhoni simbi uye yakaderera alloy simbi pakati pejoinhi yewelding yesimbi isina kufanana, kazhinji sarudza zvinoenderana nemagetsi ekushandisa negiredhi resimba rezasi resimbi.

3. Kwesimbi inodzivirira kupisa uye simbi isina tsvina, kunze kwekufungisisa simba, asiwo funga nezvekemikari yakakura yesimbi ye weld uye makemikari ezvinyorwa zvemubereki pedyo.

4. Kana kemikari yezvakagadzirwa zvemubereki, senge kabhoni kana sarufa, phosphorus nezvimwe zvinosvibisa zvinokuvadza zvakakwirira, inofanira kusarudza yakasimba mutswe inopikisa welding consumables.Zvakadai seyakaderera hydrogen mhando welding zvinodyiwa.

Funga nezvemamiriro ekushanda kwewelding uye kushandiswa kwekuita

1. Welded zvikamu munyaya yesimba remutoro uye kukanganisa mutoro, mukuwedzera kune zvinodiwa kuti ive nechokwadi chekusimba kwesimba, goho simba, kukanganisa kuoma, plasticity ndizvo zvakakwirira zvinodiwa.Panguva ino inofanira kusarudzwa ne-low-hydrogen welding material.

2. Welded mativi ari corrosion media, anofanira kusiyaniswa kubva vezvenhau mhando, concentration, kushanda tembiricha uye mhando ngura (general ngura, intergranular ngura, stress ngura, etc.), kuitira kuti vasarudze zvakakodzera Stainless simbi welding consumables.

3. Kana iyo weld ikashanda pasi pemamiriro ekupfeka, zvakakosha kusiyanisa pakati pekupfeka kwakajairika kana kukanganisa, kupfeka kwemukati kana abrasive kupfeka, kupfeka patembiricha yekamuri kana kupfeka pakupisa kwakanyanya, nezvimwewo. , kuitira kuti usarudze zvakakodzera overlay welding consumables.

4. Mune yakaderera tembiricha kana yakakwirira tembiricha welding zvikamu, vanofanira kusarudza kuti yakaderera tembiricha kana yakakwirira tembiricha michina zvinhu welding zvinhu.

Funga nezvekuoma uye maitiro ezvimiro zvezvikamu zvakasungirirwa, welded joint type, nezvimwe.

1. Chimiro chakaoma kana hukuru hukuru hwezvikamu zvakashongedzwa, nekuda kwesimbi yayo yekuputika mumhepo inotonhorera yekushungurudzika kwemukati inogadzirwa nehombe, nyore kugadzira kuputika.Naizvozvo, zvinodikanwa kushandisa welding zvinodyiwa zvine yakanaka crack resistance, yakadai seyepasi-hydrogen type welding rod, high toughness welding rod.

2. Kune mamwe majoini ane mabheji madiki, kana majoini ane kudzora kwakasimba kwekupinza kwemidzi, izvo zvinopisa zvinoshandiswa zvine hudzamu hukuru hwekusanganisa kana kupinda kunofanira kushandiswa.

3. Pamusana pezvipingamupinyi zvezvimwe zvikamu zvekutsvaira zvakaoma kuchenesa, zvinofanirwa kufunga nezvekushandiswa kwemarara, oxidation uye maitiro emafuta haanzwisisi kune welding zvinhu, zvakadai se acid welding rod, kuitira kuti irege kubudisa kukanganisa kwakadai seporosity.

Funga nezve nzvimbo yenzvimbo ye weld

Zvimwe zvekushandisa zvinopisa zvakakodzerwa chete nekuputira mune imwe nzvimbo, zvimwe zvinzvimbo hazviite zvishoma kana welding, zvimwe zvekutengesa zvinodyiwa zvinokwanisa kuputika munzvimbo dzakasiyana-siyana, maitiro echinzvimbo chewelding anofanirwa kutariswa pakusarudza.

Funga welding mamiriro ekushanda, nzvimbo yekushanda

1. Iko hakuna DC welding muchina zviitiko, inofanira kushandisa AC uye DC dual-use welding material.

2. Imwe simbi (senge pearlite inopisa-inodzivirira simbi) inoda kuve post-weld kusagadzikana kunetseka kupisa kurapwa, asi nemamiriro emidziyo kana zvipingamupinyi zvayo uye haigone kuitwa, inofanira kusarudzwa neyakagadzika simbi kemikari yakagadzirwa. zvakasiyana welding consumables (senge austenitic Stainless Stainless Welding Consumables), inogona kuregererwa kubva kune post-weld kupisa kurapwa.

3. Inofanira kunge yakavakirwa pamamiriro enzvimbo yekuvaka, senge mashandiro emunda, welding nzvimbo yebasa, nezvimwewo kune zvine musoro kusarudzwa kwekushandisa welding.

4. Munzvimbo umo maelectrode ane acidic uye alkaline welding anogona kushandiswa, acidic welding electrodes inofanira kushandiswa kusvika painobvira tichitarisa zvinodiwa zvakanyanya zvealkaline welding electrode yemaitiro ekushanda nekugadzirira kuvaka.

Funga nezvehupfumi hwewelding

1. Edza kushandisa zvinodhura-zvinobudirira welding consumables, kunze kwekuti kushanda kwekushandiswa kunovimbiswa.

2. Zvigadzirwa zvakasiyana-siyana zvekugadzira zvinogona kushandiswa zvekutanga uye zvechipiri welds nezvinodiwa zvakasiyana-siyana zvekushanda, uye usatsvake kushanda kwakakwana kwezvigadzirwa zvekugadzira unilaterally.

Funga kushanda zvakanaka welding

Kune zvimiro zvine basa rakakura rekushongedza, zvinobatika zvakanyanya zvinogoneka zvinofanirwa kushandiswa zvakanyanya sezvinobvira kana zviripo, senge welding wire, iron powder welding tsvimbo, inobudirira Stainless steel welding tsvimbo, nezvimwe.
