PRODUCTION OF BIMETALLIC MATERIALS WITH THE USE OF SPECIAL HOLDING ELEMENTS

The analysis of existing methods and a new combined process of bimetal production are presented, according to which a special regular design of holders is created on the surface of its functional component by means of laser or arc welding. Themelt of the structural component of the bimetal is fed to the surface of the functional component through the hole in the form of a special device with a given flow rate. Holders are made of wire. The holders are located on the surface of the working plate at an angle or perpendicular to the base, followed by bending after assembly. The number of holders, their geometry and relative position on the surface are determined by the size of the bimetal. You can change the required parameters of the strength of adhesion in different areas. Full filling of technological space between holders filled with metal guarantees reliable fastening ofbimetallic plates. Various options have been developed and implemented to reduce the cost of bimetal production technology. There are options where not the whole surface is filled, but only the specified areas of the prepared holes. This allows to implement multi-layer metal structures. A cheap and simple method of obtaining bimetallic plates without the need for foundry operations and equipment is the use of welding technology. It has been proven that in order to ensure high bond strength of bimetallic components and uniform distribution on the joint plane, it is necessary that the frequency of the holders and the step between them havethe optimal value. The high efficiency of a new, innovative combined technology of bimetal production has been demonstrated.The introduction of these technologies in the production of bimetals does not require large material costs and ensures maximum profitability of the manufacturing process of such materials. The presence of several manufacturing methods allows you to select the most optimal technology depending on the volume of production and the size of the resulting sheets of bimetals or individual products from them.
