摘要： PURPOSE:To enable using for parts for which mixing of foreign matters to inside of the tube is objectionable by manufacturing an aluminium alloy electric welded tube inner circumferential face of which is clad with brazing filler metal and heating to specified temperature in inert gaseous atmosphere and then cooling. CONSTITUTION:One side of aluminium alloy parent metal 3 is clad with brazing filler metal, for instance consisting of Al-Si group alloy, having thickness of several %-ten odd % of the parent metal 3. This material is made to an electric welded tube by usual method. Inner burrs 1 and spatters 2 remain at the inside face of the electric welded tube as foreign matters. This electric welded tube is then heated to above melting point of the brazing filler metal 4 in vacuum or inert gaseous atmosphere and cooled. The inner burrs 1 and spatters 2 which are possible to come off are welded metallurgically to inner face of the tube by the brazing filler metal 4. By this way, range of application of the electric welded tube can be enlarged.

摘要： PURPOSE:To improve water wettability and corrosion resistance by providing an oxide film formed by an anodization method on the surface of a titled member and packing a Zn-Si compd. in the pores of the film. CONSTITUTION:Al or Al alloy member as an anode is electrolyzed in an aq. soln. of an oxalic acid, chromic acid, sulfuric acid, etc. to form an oxide film on the surface thereon. Pores having 100-500Angstrom diameter are numerously formed in the film. The member is then dipped in an aq. 5-10% sodium silicate soln. added with 1-5% pulverous powder of metallic zinc or zinc oxide powder to penetrate said metals in the pores of the oxide film. When the member is pulled up and is heated, a Zn-Si compd. is packed in the pores. The member is dipped, if necessary, in a chemical conversion liquid contg. chromate or dichromate to adsorb and fix the chromate or dichromate on the Zn-Si compd.

摘要： PURPOSE:To obtain a brazed product high in corrosion resistance, by vacuum- brazing or atmospheric-brazing an Almaterial after performing chemical zinc plating and thereby carrying out a zinc diffusion process simultaneously during brazing. CONSTITUTION:An Al material is defatted and cleaned, and chemically etched. Then chemical zinc plating is performed. This product is then set to a jig and vacuum-brazed or atmospheric-brazed. The zinc plating layer diffuses into the brazing filler metal in the course of brazing and heating, and a zinc diffusion layer is formed on the surface layer of the Al material. Consequently, corrosion resistance of Al material is improved and durability is increased.

摘要： PURPOSE:To prevent the decrease in the remaining content of zinc in clad parts even after a vacuum brazing stage and to obtain a clad material having good pitting resistance by inserting zinc between a base material and a clad layer in the stage of manufacturing the clad material. CONSTITUTION:A several mu pure zinc layer 2 is stuck on a base material 1 side by a vapor deposition, melt spraying or other method. Thereafter, an Al alloy 3 (pure Al, Al-Mn alloy, Al-Zn alloy, etc.) to form a clad layer is press stuck to the material 1 by rolling, whereby a clad material is obtained. If such material is utilized for a part of parts to be vacuum brazed, the layer 2 diffuses in the material 1 and the layer 3, and the clad material having excellent pitting resistance is obtained.

摘要： PURPOSE:To obtain an acicular fin heat exchanger tube of small pressure loss and small heat transmission resistance by winding U-shaped fin meterial provided with a wound part formed from a beltlike metallic sheet clad with a brazing filler metal on both sides on a tube and joining them by brazing. CONSTITUTION:A beltlike metallic sheet 14 of thickness (t) obtained by covering a brazing filler metal such as Al-Si alloy on both sides of a rolled metallic material 12 such as Al is blanked to form an acicular fin 11. The width W of the acicular fin is made nearly equal to the thickness of the metallic material 12. The acicular fin part 11 is then set upright by folding to form a U-shape, and the wound part 16 is wound spirally on the surface of a heat exchanger tube 15 to set the acicular fin 11 at nearly right angles to the axial direction of the heat exchanger tube 15. Next, the wound part 16 and heat exchanger tube 15 are brazed by heating in a brazing furnace. The brazing filler metal 13 flows into the periphery of rectangular section of the acicular fin 11 by surface tension when the brazing filler metal melts. Thus, acicular fin 11 having circular sectional form is obtained.

摘要： PURPOSE:To facilitate brazing of fins, by fitting the tapered and corrugated fins to the gaps between neighboring coiled tubes, and by brazing them after bringing the supporting plate of the fin side into contact with a proper place of the both end of the fin width direction. CONSTITUTION:In the gap between flattenend coil tubes 3, a tapered and corrugated fin is fitted, and set by a mounting jig comprising upper and lower supporting plates 9, 8 and a supporting column 10. A supporting device comprising a supporting plate 13 of a fin side and a holding member 14 of a supporting plate is connected to the said mounting jig. The part (b) of a half the height of a fin 2, or the projected or the recessed part or its vicinity of the fin 2 in contact with the tube 3, are brought into contact with and supported by a supporting plate 13. Then, even in the case of the load by a wedge 12 in the direction of lessening the gap between the supporting plate 8, 9, or of a compressing load due to the difference of a heat expansion during brazing, the fins 2 are prevented from dislocating. In the mean time, the jig and the supporting plate 13 are removed after brazing.
