Welding Upset Force. Because of the element of preheat with Low-Force Friction Welding you can make very low upset welds they take on more of a bulge shape as opposed to the predominant flash curl typically generated by traditional friction welding. This forging action results in residual molten material being expelled and forging of the underlying solid metal.
Many textbooks said that the upset welding is the typical resistance welding process. The process can be and shall be explained with the simple one- dimensional heat conduction model Electro es Squeeze Heating time Electrode force ding current Start Of process Movement Of n Time Upset Forge force Upset distance Distance to start upset tm e Current. Magnetic force upset welding MFUW differs from conventional resistance welding in that a forging weld force is applied by a 120-hertz electromagnet.

The coalescence is produced over the entire area by the heat generated from the resistance of the electric current flow through the contact area of the abutting surfaces. Because of the element of preheat with Low-Force Friction Welding you can make very low upset welds they take on more of a bulge shape as opposed to the predominant flash curl typically generated by traditional friction welding. The specimen with maximum torsion strength has more precipitates in grains of microstructures compared to that of specimen with lower torsion strength. The coalescence is produced over the entire area by the heat generated from the resistance of the electric current flow through the contact area of the abutting surfaces.
