Difference Between Hot Riveting and Cold RivetingMechanical Engineering Related Difference Between hot welding and rivetingAs welding, rivet is also a permanent binding process used for mechanical assembly of two or more solid components. In the riveting, the hole arrays are first drilled into the components in the predefined places. The additional belt plates, if used, are also perforated at the corresponding locations. Then, specific dimension clusters are inserted through these holes. The diameter of the hole perforated in the components is greater than the diameter of the handle of the rivets, but less than the diameter of the head of the rivet. The length of the rivet crank should be substantially greater than the cumulative width (or thickness) of the additional components and belts. the protrusion part of the rivet blanket is bothered by hammering to produce a closing head on the opposite side of the heat of the rivet. Stresses (tensils or compressives, based on the riveting method) developed within the rivets helps to firmly mount the components. The magnitude of the compressive force necessary to alter the protrusion end of the rivet depends mainly on the size of the rivet and the rivet material. This requirement of strength or pressure can be substantially reduced by heating the protrusion end of the rivet before disturbing. As a result, two different riveting methods have evolved: hot riveting and cold riveting. When the protruding end of the rivet blanket is heated at a high temperature before it is altered, then it is called a hot rivet. The temperature is usually between 50% – 70% of the melting point of the riveting material. The greatest advantage that can be achieved due to heating is the substantial reduction of the hammer force or the pressure requirement for the same size and riveting material. In addition, it offers tight fixing and improved leakproof joints. However, it requires external heat source and therefore additional accessories and the corresponding cost. In addition, it is not suitable for heat-sensitive materials. In the cold rivet, the protruding end of the rivet blanket can be hammered directly without heating (i.e., the anger is carried out at room temperature). Although it does not require heat source, it is not efficient for large diameter rivets as the very high compressive force is desired for anger. Below are several similarities and differences between the hot rivet and the cold rivet in table format. Similarities between hot riveting and cold rivetDifferences between hot rivet and cold rivet Hot water Cold Riveting In the hot rivet, the protrusion end of the rivet herd (opposite to the head) is heated at a high temperature (about 2/3 of the melting temperature of the rivet material). So annoying is done at high temperature. It's cold, it's not such heating. The assembly is carried out at room temperature. For hot riveting, the rivet material remains in plastic condition due to heating, and therefore a significantly lower pressure is required to apply on the matrix. In the cold riveting, more pressure is required comparatively to apply on the matrix for the same rivet material and size. The external heat source is necessary to raise the temperature of the rivet. No such heat source is required. Since the heating process requires time, so hot is a time-consuming process. The cold riveting is efficient in time, as no heating is done. Due to automatic volumetric contraction during cooling (after cooling), traction stress develops within the rivet blanket. Helps keep the pieces mounted with strength. In the cold riveting, no such tensile tension is developed within the rivet blanket (because the temperature change does not occur here). Consequently, the grip force is less. Due to the strong grip force, the joints are usually leak resistant. Cold riveting is not recommended for fluid-tight binding purposes. In the hot rivet, the shadow of the rivet is subjected to the stress of the ear and tensile stress. In the cold rivet, the chunk of the rivet is subjected to havoc. It is suitable when the rivet material is ferrous and/or rivet diameter is greater than 10mm. For non-ferrous rivets (such as aluminum, brass, etc.) of small diameter, cold rivets can be made.
