Svarochnoye proizvodstvo, 1961, No. 4, pp. 27 29 TEXT: Investigations were made to develop improved methods of.joining the.oontacts to.theadapters of magnetic starters and i~ was found that the best. method for this purpose was the spot welding process. VNIIES0 designed in 1957 ~together with the ".Elektrie; plant a spot welding machine MTnK -25 (RrPK-25) in- tended for the welding of contacts.,.This machine became operative at the Riga Plant of Electrical Machinebuilding and was used for the weldIng of three types of silver contacts. Savings in silver amounted to 1500 kg In 1960 and w-re achieved by a modified design of the contact, i.e., smaller dimtnsions of Its stem. (Fig. 1) During welding only the stem is fused. Small sUver contacts are welded to 0.25 mrn thick BrOcO 6-5 - 0.15 (BroF6 .5-0-15) bronze bridges (2a) using the followlng procedure: Stage - 11; compression 0.28 see; welding 0.22 see, forging -0.22 see; pulse 0.04 - 0.06 see; heating 5 - 14 grad%tation marks) Card 1/6 S/135/6i,/ooo/1oo4/b4)8/1b12 Welding of Electric Contacts of a Magnetic Starter A0061AI01 pr soure -60 ated P" and 10" e 100 kg.- Silver contacts are welded to zino-pl grade inaised.steel. bridges-,(Pig. 2b) as followst stage VI-V111; compresaiion .0.28. secj welding 0.1 - 0.28 sea; forging - 0.05 - 0. 1 ~ sea; pulse O.Ok 0,06 see; heating 10 - 14 graduation marksl :,Pressure 80 - 100 kg. Silver-contaots can be welded to steel contadt bolts under analogous conditicna. Welding of,tontaots on the MTPK-25 machine ishighly efficient, namely 1250 - 1300 spots per h. A now. design of a magnetic starter 1 QMP-2 (EMR-2) developed in 1959 at the REZ called for a -technology of welding dermet contacts with bronze and steel. At the I U~ tute.of Metallurgy imeni A.A. Baykov AS USSR together with REZ Investigations were made on the ultrasonic welding'of CH -40 (SN-40) cermet contacts (40% nickel, 60% silver),and OK-15 contacts (15% cadmium oxide, 85% silver) with bronze and silver on the Y3CM1 .(UZSM-1) ultrasonic machine with y3r .1o (uzo-jo) oscillator of ',wo systems Investigated 1):transmission of oscillations through the contaqtt 2) transmission of oscillations through the bridge (Fig. 4a,b) - the second method proved more satisfactory. Welding was performed at 12 - 14 micron amplitude; 100 kg contact force; 0.6 see welding time. The small cemet contacts welded to bronze bridges showed high strength charactt~ristics exceeding those presoribed by techni- cal specifications. On the.basis.of results obtained theultrasonic welding of these parts can be recommended for'extended industrial,.use.

The authors conclude that the results of tests of the sensitivity of the gamma-method, as obtained from flaw-containing specimens accepted in the field and recommended in the literature, are higher than the actual values. Therefore, in order to obtain the correct sensitivity characteristics of the meth d employed in the detection f natural defe ts, -if is essential to em js 0 ntaining artificially 0 c PI pecimens co induced defects which closely approximate the shape and size of the natural de- fects. Such artificial flaws may have the shape of cylindrical openfn'gs 1 - 1.5 mm in diameter or of channels 1.5 mm wide and 1.5 mm long. The radioactive in- tensity of the source does not affect the percent.ile or the absolute sensitivity of the method, providing the components being examined are made of thin steel. The ease of detection.of defects by means of the t-method is determined by the size of the, defects. The percentile sensitivity is reduced by one-half if the distance between the (-iay source and the component being examined is.de- creased from 8.00 to 200.mm, Regardless of the value of h, the minimum focal length which produces optimum percentile sensitivity lies in the range between 400 and 600 mm.

(USSR) ABSTRACT: The Russian-climate does not allow concreting during winter without pre-heating of all materials. Pre- heating by-moans of steam involves many difficulties; experience in using no-fine concrete and electrical pre-heating was obtained'during tho'construction of Karagandinsk GRES-2.(power station). Concreting was. out continuously from December to April. The carried . mean monthly'temperature In December was - 11.30p in Jantiar~ 15.69'r in February - 16,700 and'in March 7.90. The lowest temperature was - 420. The velocity- of north-west winds reached 12-m/sea. Because of con- drete porosity., the'formati6n of steam is rather ex- haustive during pro-heatingv which can result In over.; drying.- To.obviate this, the maximal temperature for pre-heating no-fine concrete is lower than that of dense conc.retep and should not exaged 33-3500. The consumption of electricity per 1 mO of no-fine *on- Card 1/4 Orete is 20% lower than for dense concrete. The current Porous Electrical. Curing ~of Coarsely/ Concrete, 97-57-9-8/17 for pre-heatingvas 66-88 V., Fig- I shows the Used temperature variation of no -fine concrete *during pre- heating; it~shows a-continuous'rise of 5-70 an'hour 4n tdmperature-ddring, 5-6 hours. 6ix hours after the. commencement of pre-~heating, the temperature reached thd,maximum, and further increase in temperature was p~revented by repeatedly switching off the current.. After i4-15 hours of pre-heatingp the power was finally switched off., The cooling down Idsted 9-10 houral that Lap It was slowerthan warming up, During this cooling time,the concrete hardened sufficidntly ~o withstand. low temperatures..'The graph in Fig-2 shows the increase in'strehgth.of no-fine concrete Mark 50 during pre-.' heating..'The period during which the temperature in- creases corresponds with the period of initial setting. ~A sharp increase in the strength of the concrete occurred during the'period of the highest temperature (shown on Fi~te1between the limits of the practically ,horizontal line)., In that time the strength of the conerete.reached 805% df the final strength. Later, when the temp6raturelhlls, the strength increases at Card a slower rate.

If the temperature is lowe than -150C-P 2% calcium chloride (by weight of oemenJ Is added. This lowers the freezing pointo and in- creases the dleotro-conduativity of the mixtures The h in Fig.3 represents the pro-heating temperature gfrlhe concrete mix containing calcium chloride addi- tive. This additive shortens the time of pre-heating and also the tinie of hardening. The quality of pre- heating of concrete depends largely on the shape and location of the electrodes. At-first,, steel plates were used fixed to form-workil but these proved un- satisfactory.,'as the paths of concrete immediately adjacent to the plates become overheated. Rod-type electrodes proved to be better, and were made from the waste of rein'Lorcement.steals' 4-6 mm diameter. The distance between electrodes was 25-27 cm. Fig-4 gives an'illustration of a wall built from no-fine concrete. -In using these electrodes no aver-heating of concrete was,experienced. Overheating may result if the temperature reaches 40-420, and this is ob- viated by'switching the current off; the concrete Is Card 3/4 allowed to cooldown to 20-260# and the current is, 0 0~1 0 0 9 -0. 04 LA h 70 0 6 1 IMP 0 covit Awl If-o -Abindatem A&Y Is tA XWvb*UG WL A. 1. and IL X UsUmenka (kkk MdaUj (L4U mtkip), ISK (4). 0 I)Wdbes an expedurcut tat Obwning a tit&fdum- 0 aluminfun, 4arin anlkwy b"6 for tho ebdrdyUa prutfookm ormiumbdum. 00 0 The both waacb&V WM7Wp.
