Tbo only trouble no that X kept up that poee, and tbo other half of tbo duot didn't -- I finished the piece, bowed, and Left the etaga Wiilo tho othar bey woe itill frantically scrambling through the final bard The eudienco enjoyod tbo aituatlon wtalo-boartodly, but 1 can't say the porfonaere did . and much cm X want to ontortaia you toddy, I don't want to do It la each a drastic faahlonl Thay toll mo tv eohjoct for tocjy Is eoldar.

Rost solder is still used In snob the sane shape and fern that It has boon for hundreds of years -- with tbs poesibla exception of core solder* Our consumption of solder In this country la Impressive) there are several sots of figures that give us a rough Idea of hit It Is currently. The L. I. A. report for 1951, (figures bisod on domestic ehlpaonte In short tons) gives tbi 1950 total as 91,001 -- load eontont 70,691) the 1951 total as 70,636, laid content 53,737. Tho L. I. A. estimate of do* nestle lead consumption for eoldsr only, in short tons, was 65, H5 for 1951, and 66,120 for 1950. Tho 0. S. Bureau of Kinos also gives us soma data in tbs form of estimated tin eonsuention In soldor manufactures 1950 - 27,160 long tens, and 1951 - 1SP08 long tona. All those figures how a drop in 1951. Thu reason for this was tho rush created fcy the Korean aituatlon -- as S. K.

Boeauso soldoring prooossos hare b an such e swan knododgo for so long, thcro hasn't boon ouch published literature on solder or soldering. To fill this grp in the nation's library of printed .attar, the African t-ldlng Socloty Is now sponsoring r tort on molding with a supplementary test containing notorial on soldering. The subcoswdttoe on soldering, conposod of neaeers of tho L. I. A., has alrondT bold a nesting and watllncd its general procedure; pruliadnary writing assign. eats have boon distributed. To got back to factors affecting solder todays tin content is a problem. Sons factors make It doslrable to maintain tin content of solders st a irt h . -- the war situation *nd tin controls, and tho coot of nanufftcturo. But -- low tin oontent -ldors remain unpopular. An azaaplo is auto body soldjrs. -a a nenber of tho tin odviaory comntiioo to g. F. A.

Though low tin content solders can bo offuctively used onco tho operator Ks learned tho techniques, and though tho techniques aro not inpoaaibly difficult, poopie continue to show uilllngnoaa to pay pronlaun prices for high tln-eor.tont solders -- oron on the black market! Wow spoclal solders cro, of course, keeping paco with our modern duvolopmonta in aircraft, guldod nlssllus, Jot and rocket onglnos, and the llko. Their properties arc being adjuatod to today's changing needs higher touporaturcs, greater croop strength, greeter Impact strength, batter electrical conductivity ... or special lew tonpcrcturo properties, or apodal wetting proportlts. For axompla, there ere tho solders used for ellror printed circuits, md for glass. In eonnoctlon with ary discussion of soldur. It is only fitting that some mention bo nado of soldering fluxes. This field offers even marw potential in tho nwtallurcr of solder thro solder itself -- providing expanding fields of operation. Materials such as tine chloride and rosli^ while atill holding n big piece, here rwoontly boon inoorporstud with otbur ehmiools to lssproru their action tremendously -- and, lndoed, a mo of tho new chodoale have supplanted thsso nateriale entirely in oortlan flolde.
