New Techniques in the Field of Resistance Welding

Welding today can be found in numerous industries. One sector of the welding industry that is growing today is resistance welding. This is a thermal procedure where two parts to be joined are warmed to the melting point and then melted together, therefore forming one body when the weld cools. This procedure resembles various other kinds of welding, but also with several distinctions. The first of these differences is of course the size of the parts and welding components included. How can this new technology with resistance welding help your project?

 Resistance Welding for your Next Project

Micro resistance welders are systems consisting of the welder itself which is a box with the electronic devices and controls for controlling the weld process, and the weld head which holds the micro electrodes and brings them into contact with the parts to be welded. The micro electrodes themselves are really little contact points, as small as .010 of an inch square. The welders have very precision electrical current control and the weld heads have extremely precise force control to prevent breaking the delicate electrodes.

The 3 opposing electrode types of micro resistance welding consist of a straight through weld, seam weld, and projection welds. In a straight-through weld the electrodes are contrary to each other on either side of the materials to be bonded, and electrical present travel through the materials heating them at the intersection point, forming a weld. A seam weld is in fact the exact same as the straight-through weld other than that either the electrodes or the work-pieces are moved along to form a continuous series of overlapping spots.

 Finding New Resistance Welding Practices

The primary step to carry out micro resistance welding is to put the two parts on top of each other above a copper electrode. Then the weld head brings a leading electrode down onto the point of weld, compression the 2 reconstruct. With the 2 pieces squeezed together, electrical current is gone through the electrodes and the part at the point of crossway. The product heats up quickly, melting both pieces where they call between the 2 electrodes.

In conclusion, resistance welding is a popular option for joining little parts. It is reduced cost, clean, safe, and fast. These advantages make welding a growing industry today. Would you like to learn more about resistance welding?
