    The invention relates to a method for the manufacture of a metallic matrix which is "monolithic", is coated with a catalysis promoting metal oxide and is disposed in a metal casing, in which the matrix is composed of alternately disposed plain and corrugated or folded metal sheets or plates, in which these sheets are stacked in a pile or are wound into a spiral. The method comprises a special resistance welding on the end faces of the matrix and arc welding of the side face of the matrix to the side of the casing, on which the metal oxide is applied.

    2 o Way to pop. 1, I differ by the fact that in the process of welding the ends of the die, the welding current is repeatedly passed through the electrode plates, turning the die about its vertical axis.
    .3. The method of claim 1, wherein what
    protective gas is supplied to the welding zone.
    4. The method according to paragraphs. 1, 2 and 3, characterized in that after welding the matrix with the housing, a finely divided, accelerated catalysis of the metal oxide is applied to the resulting assembly at the ends, and the oxide-coated assembly is dried and annealed.
    The invention relates to methods for the manufacture of devices intended to accelerate the catalysis of a metal oxide.
    It is known the use of monolithic metal elements, as a structural catalyst enhancers when cleaning the exhaust gases of an automobile engine 1,
    However, these devices do not satisfy the requirements for the mechanical stability of such metal catalyst boosters in modern internal combustion engines. A very strong exhaust gas pulsations are observed during the operation of a piston engine, in order to eliminate which it is necessary to rigidly connect RANU1- successively laid smooth wave to wavy or corrugated steel. sheets using proper techniques.
    Lime is a method of manufacturing catalysis accelerators, including the manufacture of a metal matrix with a coating of accelerated catalysts of metal oxide, in which smooth and corrugated or corrugated sheets of oxidized and resistant to high temperatures of the metal are collected in a package or wound in a spiral fashion and are welded: between them, set the matrix in metal- body and weld the matrix with it
    However, the known method is complex in execution, and the matrix, made by this method, do not have sufficient strength
    The purpose of the invention is to simplify the manufacturing process and increase the strength of the die.
    To achieve this goal in the manufacture of catalysis accelerators, we turn on the fabrication of a metal matrix with metal acceleration to catalysis of metal oxide, in which smooth and corrugated or corrugated sheets of oxidized and high temperature metal are collected in a package or

    wound in a spiral manner and weld between them, install the matrix in a metal case and weld the matrix with it; during the matrix welding process, assembled sheets are installed with an end on an electrode plate connected to one pole of the current source, and the second end of the current pole is mounted on the other end electrode plate, at least one impulse of welding current is passed through the plates, then the matrix is turned over, the positions are changed, and the welding process is repeated, the matrix and body are welded stvl dissolved arc directing emoy claim body in accordance with a desired weld configuration wherein proplavl dissolved at least the outer layer of the matrix, and after the welding of the matrix with the housing cover from within the resulting assembly iitsim accelerated catalysis of the metal oxide.
    In the process of welding the ends of the matrix, the welding current is repeatedly passed through the electrode plates, while turning the matrix 14U relative to its vertical axis.
    Shielding gas may be supplied to the weld zone.
    After welding the matrix with the housing, a finely divided, accelerating catalysis of the metal oxide is applied to the resulting unit from the ends, and the oxide-coated unit is dried and annealed.
    FIG. 1 shows an installation for end welding of smooth and deformed metal sheets in FIG. 2 shows an installation for obtaining a rigid welded joint between a die and a housing in FIG. 3, a corrugated electrode plate for face welding, a cross section; FIG. 4 shows various variants of the weld between the catalysis accelerator and the housing.
    To implement the proposed method, an electrode holder 1 with a supply of protective gas is used. welding electrode 2. A metal matrix 3 is installed between the HfcjMH electro shed plates 4 made of copper. The matrix with both copper plates is placed on the mounting plate 5. The electrode holder 1 is through an ammeter 6, the mounting plate is connected directly to the current source 7. As the lower electrode plate 4 using a corrugated plate. In this case, the corrugated upper electrode plate 4 can also be used. The best welding results are obtained when the distances between the dividing valleys of the ridges of the corrugations correspond to the distances between the smooth sheets of the matrix. The uniformity of end welding can be enhanced by welding the welding current through the installation many times and, as necessary, the matrix installed on the lower electrode plate from time to time is rotated around its vertical axis. As in face welding, as well as in welding from the side of the body, protective gas can be used, since this is required by the materials used. During the coating process, accelerating catalysis of metal oxide on the welded structure. Proceed as follows: the body and the still uncoated composite element are deposited on the butt-welded side and the dispersion is accelerated to catalyze the metal oxide, the pergator is removed by drying and finally the coated element is annealed. It is advisable to use at least. for matrix, scale-resistant and resistant to high temperatures, an alloy of chromium steel containing aluminum. In this case, the constituent element, prior to the application of a metal oxide decomposition, is preliminarily burned out in an oxygen-containing atmosphere at 600–1200 ° C. The invention allows, by simple means, to weld alternately stacked corrugated or corrugated and smooth metal layers into a monolithic enhancer matrix, and fix this matrix in a metal case. Compared with the known methods, in this case much less time and minimum of funds are required. In addition, the proposed method is completely safe. The matrix installed according to the invention in a housing and provided with an accelerating catalysis of a metal oxide oxide in comparison with known dies has an unexpectedly high mechanical strength, proved by measuring the force required for extrusion from the side. Tests have shown that the accelerators manufactured according to the proposed method have an enhanced matrix strength with greater ease of manufacture compared to accelerators manufactured by a known method.
