What are the characteristics of fuses? What are the properties of welding wire?
Normally used fuses and solder are usually alloys of lead and tin, but only in varying proportions.Solder has a slightly higher tin content and a slightly lower melting point. The most commonly used melting point is about 220 degrees celsius.If the electric iron with higher power and the appropriate soldering flux, the fuse can barely be used for welding.
The fuse is fused when the current is overloaded. The wire is fused with iron and rhodium to weld the circuit board
A fuse is also called a fuse, and the IEC127 standard defines it as a fuse (fuse-link)". The utility model relates to an electric component which is arranged in a circuit and ensures the safe operation of the circuit. When the current flows through the conductor, the conductor will be heated because of the resistance of the conductor. And heat follow this formula: Q=0.24I2RT; Q is the heat, the 0.24 is a constant, I is the current flowing through the conductor, R is the resistance of a conductor, T is the current through the conductor time; so the formula we can see that the principle of simple fuse.1 、 over current protection and over temperature protection. A fuse used for overcurrent protection is a fuse (also called a current limiting fuse) as it usually is.2. Fuses used for overheating protection are generally referred to as "temperature fuses"". The temperature fuse is divided into the low melting point alloy shape and the temperature sensitive trigger shape, as well as the memory alloy shape and so on. The temperature fuse is used for preventing the heating appliance or the heating device from being too high and the temperature is too high to protect.Welding wire is used as filler metal or metal wire welding material at the same time as conductive.1, in gas welding and gas tungsten arc welding, welding wire for filler metal;2. In submerged arc welding, electroslag welding and other gas shielded arc welding, the welding wire is both a filler metal and a conductive electrode.3, the surface of the wire is not coated with anti oxidation flux.
