Brazing The Delicate Craftsman fun konge Didapọ

Brazing ko ni yo irin ipilẹ ṣugbọn o ṣaṣeyọri didapọ nipasẹ yo irin-ipo-iyọ-kekere brazing filler lati kun awọn ela. O ṣe ẹya alapin welds ati kekere abuku, ṣiṣe awọn ti o dara fun alurinmorin konge irinše, dissimilar ohun elo, ati eka ẹya. O ṣe pataki ni awọn aaye bii itanna, afẹfẹ afẹfẹ, ati ohun elo iṣoogun. Ni ibamu si awọn yo ojuami ti awọn brazing kikun irin, brazing ti wa ni pin si meji isori: rirọ brazing ati lile brazing.

(I) Asọ Brazing: Awọn "Micro-Didapọ" fun Itanna irinše

Rirọ brazing nlo irin kikun brazing pẹlu aaye yo ni isalẹ 450°C. Irin kikun brazing ti o wọpọ ti a lo jẹ alloy tin-lead (diẹdiẹ rọpo nipasẹ alloy tin-free tin). Flux ti lo lakoko alurinmorin lati yọ awọn fiimu oxide kuro ati dinku ẹdọfu oju. O dara fun sisopọ deede ti awọn paati itanna, awọn igbimọ iyika, ati awọn isẹpo paipu omi, laarin eyiti soldering jẹ imọ-ẹrọ brazing asọ ti o jẹ aṣoju julọ.

1. Soldering: The "Ipilẹ Olorijori" fun Circuit Board Welding

Ilana: Irin tita kan mu igbona iṣẹ-ṣiṣe (iwọn otutu 250-350 ° C), yo okun waya ti ko ni asiwaju (ojuami yo to 227 ° C). Labẹ iṣe ti ṣiṣan, tin didan kun aafo laarin awọn pinni paati ati awọn paadi igbimọ Circuit, ti o n ṣe isẹpo solder lẹhin itutu agbaiye.

Awọn aaye Iṣiṣẹ:

Mimọ alurinmorin-tẹlẹ: Lo iwe-iyanrin lati ṣe didan awọn pinni paati ati awọn paadi lati yọ awọn ipele oxide kuro; nu awọn Circuit ọkọ pẹlu oti lati yọ awọn abawọn epo ki o si yago tutu soldering.

Imọ-ẹrọ Alapapo: Ni akọkọ, mu ṣoki irin tita si olubasọrọ pẹlu iṣẹ-iṣẹ (ipapọ ti pin ati paadi). Lẹhin alapapo fun iṣẹju 1-2, ifunni okun waya tin. Yago fun alapapo taara waya Tinah, eyiti o le fa “soldering tutu” (Tinah didà kuna lati tutu ni kikun iṣẹ-iṣẹ naa).

Iṣakoso Ijọpọ Solder: Iye okun waya tin yẹ ki o jẹ “to lati kun aafo naa laisi ṣiṣan.” Apapọ solder yẹ ki o jẹ "conical." Maṣe gbọn paati ṣaaju itutu agbaiye lati ṣe idiwọ fifọ apapọ solder.

(II) Lile Brazing: “Ẹri Gbẹkẹle” fun Awọn ohun elo Itọkasi Agbara-giga

Lile brazing nlo irin kikun brazing pẹlu aaye yo loke 450°C. Awọn ohun elo brazing ti o wọpọ ti a lo jẹ alloy Ejò-zinc (filler brazing brass) ati alloy orisun fadaka (filler brazing fadaka). O ṣe ẹya iwọn otutu alurinmorin giga ati agbara weld giga, ti o jẹ ki o dara fun alurinmorin awọn ohun elo titọ agbara-giga gẹgẹbi awọn irinṣẹ gige, awọn paarọ ooru, ati awọn abẹfẹlẹ aero-engine.

Awọn aaye iṣẹ: Ṣaju irin ipilẹ ṣaaju ki o to alurinmorin (iwọn otutu 300-500 ° C) lati rii daju sisan kikun ti irin kikun brazing; lo ṣiṣan bii borax ati boric acid lati yọ fiimu oxide kuro lori dada irin ipilẹ; ṣe itọju itutu agbaiye lọra lẹhin alurinmorin (fun apẹẹrẹ, gbigbe sinu apoti idabobo) lati yago fun awọn dojuijako ti o ṣẹlẹ nipasẹ awọn iyatọ iwọn otutu ti o pọ ju.

(III) Ilana yiyan ati Awọn aṣa Idagbasoke ti Awọn ọna Alurinmorin

Ni idojukọ pẹlu ọpọlọpọ awọn ọna alurinmorin, bawo ni a ṣe le yan imọ-ẹrọ ti o yẹ ni ibamu si awọn iwulo gangan jẹ bọtini si imudarasi didara alurinmorin ati ṣiṣe. Ni akoko kanna, pẹlu idagbasoke imọ-ẹrọ ile-iṣẹ, imọ-ẹrọ alurinmorin tun n dagbasoke si ọna “oye ati alawọ ewe.”

(IV) Mojuto Okunfa fun Welding Ọna Yiyan

Awọn abuda Irin Ipilẹ: Fun irin-kekere erogba, pataki ni a fun SMAW ati alurinmorin CO₂; fun irin alagbara, irin alagbara TIG ati alurinmorin lesa ni o fẹ; fun aluminiomu alloys, AC TIG alurinmorin ti yan; fun itanna irinše, soldering ti lo.

Awọn ibeere Ọja: Fun awọn paati deede (gẹgẹbi awọn ẹya aerospace), alurinmorin laser ati alurinmorin TIG ni a yan; fun ibi-produced awọn ẹya ara.
