Pehea e koho ai i ka mana o ka mīkini welding laser? Hoʻopili pololei ma muli o ka mānoanoa a me nā mea hana

Pehea e koho ai i ka mana welding laser pono  

Ka nui o ka mana = pau ka ikehu a me ke ahi; liʻiliʻi = nele i ke komo ʻana a me ka wikiwiki haʻahaʻa. E ho'ōki i ka koho ʻana—e laka wale i ʻelua mau mea: ka mānoanoa o ka ʻāpana hana a me ke ʻano mea. E hoʻohālikelike pono iā lākou a loaʻa iā ʻoe ka maikaʻi, ka wikiwiki a me nā kumukūʻai holo haʻahaʻa. Eia ka papa kuhikuhi maʻalahi-English.

1. E hoʻomaka me ka mānoanoa: ka 'mana rule-of-thumb'  

Hoʻonohonoho ka mana laser i ka hohonu o ka weld—ʻoi aku ka nui o nā metala mānoanoa. E hoʻohana i ke kila ma ke ʻano he kumu a me ka unahi mai laila.

- Pepa lahilahi (0.5–2 mm) → 500–1 000 W  

 1 mm kuhiliʻole: 800 W hāʻawi i ka palahalaha, maʻemaʻe bead ma 3–5 mm s⁻¹—kūpono no nā mea uila, mea liʻiliʻi.

- Pāpā liʻiliʻi (2–5 mm) → 1 000–2 000 W  

 3 mm kuhiliʻole: 1 500 W ma 3–5 mm s⁻¹ hāʻawi i ke komo piha ʻana me ka ʻole o nā manawa pōloli—kūpono no nā ʻāpana kaʻa, mea kuke.

- Papa mānoanoa (≥ 5 mm) → 2 000 W a piʻi  

 8 mm kila maʻalahi: 3 000 W i ka multi-mode e hoʻokō i nā hui hohonu a ikaika no nā papa hana a i ʻole nā ​​paipu.

E hoʻomanaʻo: ma ka mana like, hele mālie = weld hohonu; wikiwiki = pāpaʻu. E hoʻoponopono mua i nā watts, a laila e hoʻokani i ka wikiwiki-ʻaʻole e hoʻopā i ka mana me ka makapō.

2. Ke kumu i loko o ka metala: loaʻa i kēlā me kēia me ka 'makemake mana'  

Hoʻololi ka absorption a me ka thermal conductivity i ka pāʻani me ka mānoanoa like.

 Kūleʻa ʻole: hoʻomohu maikaʻi ʻia, ka hoʻokele waena—e hoʻohana pololei i ka pakuhi ma luna.  

 ʻO ke kila maʻemaʻe: hoʻoemi liʻiliʻi, alakaʻi hou aku; hele ~20 % kiʻekiʻe. 5 mm kila māmā → 2 000 W ma kahi o 1 500 W.  

 Aluminum: noʻonoʻo maikaʻi loa, wela wela nui. Pono hou ka wai a me nā ʻano nalu māhoe māhoe. 2 mm Al → 1 500 W ka palena iki; Hāʻawi ka 1 000 W i nā lei porous, pau ʻole.  

 Ke keleawe: ka hoʻomanaʻo kiʻekiʻe + ka hoʻokō. Pono ka hoʻomākaukau ʻana o ka ʻili (blackening) a me ≥2 500 W no 3 mm Cu.

3. ʻElua mau hana hoʻopunipuni e pale aku i ka mihi o ka mea kūʻai aku  

1. E holo mau i ka coupon ho'āʻo ma ka ʻōpala mua. E nānā i ke komo ʻana, porosity, distortion—a laila hoʻokani maikaʻi.  

2. E kūkulu i loko o kahi pale liʻiliʻi. Inā ʻokoʻa kāu mau ʻāpana 1-2 mm, e koho i ka mana waena waena (e like me 1 000 W) no laila e uhi ʻia kahi mīkini i ka pālahalaha me ka ʻole o ka hoʻonohonoho hou ʻana.

E koho i ka mana laser e pili ana i ka mānoanoa maoli a me nā mea maoli, a na kāu welder e hāʻawi i ka waiwai kiʻekiʻe - ʻaʻohe kilowatts pau ʻole, ʻaʻohe ami nāwaliwali.

Inā loaʻa iā ʻoe nā koi mīkini wili, e ʻoluʻolu e kelepona iā Ms. Zhao
