Brazing Overview

WhAT Is BRAzINg?Brain i a etod of joinin two piece of etal toeter wit a tird, olten filler etal.Te joint area i eated aboe te eltin point of te filler etal but below te eltin pointof te etal bein joined; te olten filler etal flow into te ap between te oter twoetal piece by capillary action and for a tron etallurical bond a it cool.

Of all te etod aailable for etal joinin, brain ay be te ot eratile. Braedjoint ae reat tenile trent tey are often troner tan te two etal bein bondedtoeter. Braed joint repel a and liquid, wittand ibration and oc and are unaf-fected by noral cane in teperature. Becaue te etal bein joined are not teeleelted, tey are not warped or oterwie ditorted and retain teir oriinal etalluricalcaracteritic.

Becaue braed joint ae a ery clean, well-finied appearance, brain often i te preferred bondin proce for anufacturin plub-in fiture, tool, eay contruction equipent and i-quality conuer product. Te proce i well-uited for joinin diiilar et-al, wic ie te aebly deiner ore aterial option. Cople aeblie can be anufactured in tae by uin filler etal witproreiely lower eltin point. Brain i relatiely fat and econoical, require relatiely low teperature and i ily adaptable toautoation and lean anufacturin initiatie.

WhEN BRAzINg WORks BEsTAon te any indutrial option for join-in etal, wen doe brain wor bet?Wen coniderin wic etal joinin pro-ce to cooe for a particular aebly, e-eral factor ould be conidered: trentand peranence, te pyical caracteriticof te part, te ape of te joint, and teproduction leel deired.

A own in Table 1, tere are any tec-

nique ued to join etal: ecanical et-od uc a treadin or boltin, adeiebondin, olderin, weldin and brain.Eac a it own adantae and liitation.

Brain or weldin are preferred wen trent and peranence are priary conideration.Due to te fact tat in brain a filler etal i alway ued and enerally te entire joint areai eated at te ae tie, brain i a ore robut proce. Ti ean tat te joint clear-ance, fiturin, etc are uc ore foriin in brain tan in weldin. If trent i not adeterinin factor or if te joint ay be diaebled in te future olderin, adeiebondin or a iple ecanical fatenin etod are liely better coice.

Altou brain, olderin and weldin are iilar in any repect, tere are iportant dif-

ference. solderin enerally can be done at lower teperature (below 450C), but doe notproduce a tron a joint. Weldin, a ier-teperature proce in wic te two etal tobe joined are actually elted and fued toeter, require te ot eat enery. Welded andbraed joint are uually at leat a tron a te etal bein joined. Te weldin procei ideal for application wic benefit fro ily localied, pinpoint eatin. But it i oredifficult to apply to linear joinin, not a eay to autoate, and not eaily adaptable for joininetal wit different eltin point.

tat can wittand te eat. Brain, wic wor at lower teperature, ay be te bet coice for tinner part becaue etal warpae andditortion can be iniied. spot joint can be eaily welded or braed, but linear joint are eaier to brae becaue te filler etal naturallyflow into te joint area.

Bot brain and weldin wor well for joinin etal wit iilar eltin point, but it ienerally eaier to join diiilar etal wit brain. siply cooe a filler etal wit a lowereltin point tan eiter of te etal to be joined. Wile weldin i difficult to autoatepartially or in tae, brain i a ore fleible proce; pre-fluin and pre-poitionin ta-tion can be et up to increae peed for i trouput requireent, or a coneyor can beued to tranport roup of part pat te brain tation.

so for any etal joinin procedure, brain becoe te ot loical olution. Te ad-antae and fleibility tat brain offer are ot fully realied wen te eatin proce icarefully conidered at te aebly dein tae. Part once iualied and anufactured aonolitic, one-piece unit acined out of olid bar toc can be often be produced orequicly and econoically by brain toeter one or ore etal coponent. Becaue a

hEAT sOURCEs FOR BRAzINgTe eat for brain i typically proided by a and-eld torc, a furnace or an inductioneatin yte. Oter tecnique include dip brain and reitance brain.

Torc brain i often ued for all aeblie and low-olue application. A neutralflae wit a blui to orane tip, a well-defined blui wite inner cone and no acetylenefeater wor te bet; a flae wit a colorle tip can caue oidation. Altou te qualityof te joint i larely dependent on operator ill and conitency i oetie an iue, torcbrain require only a all inetent and i ery popular.

Furnace brain doe not required a illed operator, and i often ued to brae any ae-blie at once. Ti etod i only practical if te filler etal can be pre-poitioned. Furnacenorally ut be left on 24/7 to eliinate lon tart up and cool down delay, and are notparticularly enery-efficient.

Dip brain i ued for all wire, eet and oter coponent tat are all enou to be iered. Te part are dipped in a oltenflu bat wic double a te eatin aent. Reitance brain i effectie for joinin relatiely all, ily conductie etal part. heat iproduced by te reitance of te part to te current.

Induction eat a te adantae of peed, accuracy and conitency. In a well-deined induction yte, eac part i identically poitionedin te induction coil and te filler aterial i carefully reulated. Ti type of yte conitently and quicly delier a precie aount of eatto a all area. Te induction eatin power upply internal tier can be ued to control cycle tie; teperature control feedbac for eac

indiidual part can be proided wit terocouple, IR teroeter or iual teperature enor. Induction furnace are alo aailable fori-olue brain.

TYPEs OF BRAzE JOINTsAltou tere are a wide ariety of brae joint to uit aryin part and aebly eoetrie and function, ot brae joint are ariationof one of two baic type te butt joint and te lap joint.

For application wic require a troner bond, an alternatie type of joint ay be prefer-able. Lap joint ae a larer bondin urface becaue te two etal oerlap eac oter.Terefore a troner bond i produced.

Lap joint do ae a double ticne in te joint area, wic ay be a potential proble forapplication were pace i retricted. But for plubin fiture and iilar application, tii not a proble. Te oerlappin nature of te lap joint actually ait in poitionin tepart for brain; particularly wit tubular part, te joint becoe elf-upportin becaue

Basic Brazing Procedures

DETERmINE ThE JOINT sPACINgIn te brain proce, te filler etal i drawn into te joint by a pullin force nown a capillary action durin te eat cycle. so it i par-

ticularly iportant to aintain te rit aount of pace between te part to allow ti to appen. Uually, te tronet joint are ade byallowin jut enou pace for te filler etal to f low into te joint area, typically in te rane of .001 to .005 (0.25 to .127 ). Widerpacin will enerally reult in a weaer joint.

It i alo iportant to reeber tat etal epand and contract at different rate wen eated and cooled. Particularly wen joinin diiilaretal, epanion/contraction rate ut be allowed for wen te part are poitioned.

For a tronet brae joint, te etal tat are bein joined toeterneed to be at cloe to te ae teperature. slow eat cycle enerally produce better reult tan fat eat cycle. In any brain operation,te filler etal i applied to te joint after te proper teperature i reaced. Alternatiely, brain prefor can be poitioned around te jointbefore te eat cycle bein.

CLEAN JOINTs (Not Required For Protected Atopere Brain)Part wic are braed in an open-air atopere require a two-tep cleanin operation.
