(1) brazing heating temperature lower, smooth joints, and mechanical properties change, small deformation, the precise size of the workpiece.
(2) welding dissimilar metals, welding dissimilar materials, and no strict restrictions on the workpiece thickness difference. Brazed diamond wheel (3) some brazing method can simultaneously welding weldment more multi-joint, productivity is high. (4) The brazing equipment, production and investment costs. (5) The joint strength is low, poor heat resistance, and welding Qing whole demanding Welding Wires. Applications: Brazing is not suitable for general steel structure and overloading, dynamic load the welding of the parts. Mainly used in the manufacture of precision instruments, electrical parts
Dissimilar metal components and complex sheet structure, such as laminated components, cellular structure, but also commonly used in all kinds of different lines of Brazing Alloys and
Carbide cutting tools. Brazing, the brazing contact with the workpiece surface by cleaning, lapping the form of assembly, brazing put
In the joint gap near or directly into the joint gap. When the workpiece and the solder is heated to slightly higher than the melting temperature of the solder
, The solder will melt and infiltration welding surface. The liquid solder by capillary effect, the liquidity spread along the seams. They were Brazing
Metal and filler metal between dissolved and mutual penetration of the formation of the alloy layer, the condensate after the formation of the brazing joints.
1, the joints smooth surface, good air tightness, the stability of the shape and size of the organization and performance of the weldment little change, can be connected to the phase The same or different metals and some non-metallic. Brazing, can be applied to the heating of the workpiece as a whole, a lot of welding a welding finished Joints, and improve productivity. Lower the strength of brazed joints, the use of the lap joint, and rely on to improve by increasing the length of lap Joint strength; In addition, the preparatory work before the brazing higher. At present,Welding Electrodes in mechanical, electrical, instrumentation, radio, etc. The departments have been widely used. 2, solder melting solder does not melt. In order to brazing part is securely connected, and enhance the solder attached to the role, brazing to Flux in order to remove the filler metal and the weldment surface oxides.Brazing Alloy (such as copper, silver-based, aluminum, nickel-based, etc.), with High strength can be connected to the load bearing parts, used widely, such as cemented carbide cutting tools, bicycle frame. More filler metal (such as tin, lead, bismuth, etc.), the weld strength is low, mainly used for welding does not bear the load but requires good seal weldment Such as container, instrument components. Brazing is widely used mainly in the manufacturing of mechanical, electrical, instrumentation, radio.
