What Is The Difference Between Brazing Machines And Welding Machines

There are significant differences between brazing and welding machines in multiple aspects, and the following is a detailed comparison:
working principle:
Brazing machine: The working principle is mainly to use electric current (in some cases, such as high-frequency brazing machines) or external heat sources (such as flames, resistors, etc.) to heat the brazing material and base material to a temperature above the brazing material melting point but below the base material melting point, then melt and wet the surface of the base material, fill the joint gap, and diffuse with the base material to form a metallurgical bond.
Welding machine (specifically referring to electric welding machine): The working principle is to melt the solder and the material being welded on the welding rod through the high-temperature arc generated by the instantaneous short circuit between the positive and negative poles, so as to achieve the purpose of atomic bonding. Electric welding machines use the principle of inductance to instantly convert electrical energy into thermal energy, achieving welding.
Application materials:
Brazing machine: suitable for connecting various metal materials, including copper, aluminum, steel, stainless steel, etc., especially suitable for welding amorphous materials, special materials and other difficult to weld materials.
Welding machine: mainly used for welding metal materials such as steel and aluminum, especially suitable for parts that require high strength, such as manufacturing, construction, shipbuilding, automotive and aviation fields.
Features and advantages:
Brazing machine: low welding temperature, small changes in the microstructure and mechanical properties of the base metal, and less prone to deformation; The joint is flat and beautiful, with precise dimensions; Can connect different metals; Easy to operate.
Welding machine: using electric energy, suitable for working in dry environments; Compact in size, easy to operate, convenient to use, fast in speed, and sturdy in welding seams.
Application field:
Brazing machine: widely used in aerospace, automotive manufacturing, construction engineering, electronic equipment, furniture manufacturing and other fields, especially in situations where high-precision and high-quality connections are required.
Welding machine: widely used in many industries such as manufacturing, construction, shipbuilding, automotive, and aviation, it is an indispensable tool in modern manufacturing and construction.
Equipment structure:
Brazing machine: Depending on different heating methods (such as flame, induction, resistance, etc.), there are different equipment structures, but usually include heating systems, control systems, and fixtures.
Welding machine: The structure is relatively simple, mainly composed of transformer, control system, electrodes, etc. It is a high-power transformer that can convert electrical energy into the heat energy required for welding.
In summary, there are significant differences between brazing and welding machines in terms of working principles, application materials, characteristics and advantages, application fields, and equipment structures. The choice of equipment to use depends on specific welding requirements and material characteristics.
