The Need for Micro Resistive Welding
One of the most important problems in fabricating is to join delicate metallic parts. In many case, this is a huge problem because the existing welding systems usually do not cater to small size work pieces. Another important issue is the high operating power of the equipment. In extreme cases, this power is high enough to actually melt the small work pieces.
A common task in many fabrication processes is attaching tabs and wires to work pieces. These tabs and wires are usually small with cross sections of several hundredth of an inch. Thus, the process engineers could not use the traditional welding processes for these tabs.
Micro resistance welding is one process that is allows these tabs and wires to be attached safely. In many cases, the process designers prefer having two or more welding options because of the convenience provided by the micro resistive welding system.
One of the most important aspects of the micro resistive welding systems is the fact that they utilize the same principles as other electricity powered welding system. The system works on the simple principle of electrical resistance of the metals. This resistance causes the metal to heat up to the point where a molten pool is formed between the pieces. This pool hardened in what is seen as the welded joint.
The current used in micro resistive welding system is low enough to generate heat that will cause the micro components to heat up and causes a welded joint. The process has strict safeguards in place to protect the work pieces from excessive current and heat damage. In many cases, the system is protected by a fuse that blows out when the current exceed the recommended level.
Micro resistive welding systems are an essential requirement that provide a much-needed service in fabrication systems.
