Spot welding process

What welding process is best? How to use a spot welder? Spot welding Applications. Processing and Equipment.

In the case of resistance spot welding , there are two main parts of the tooling system,.

It works by contacting copper alloy electrodes to the sheet surfaces, whereby pressure and electric current are applied and heat is generated by the passage of current through resistive materials such as low carbon steels. The spot welding process can be divided into four phases: heating, melting, melt flow dynamics, and cooling. Depending on the intensity, evaporation of material may occur. The resistance spot welding process use two copper alloy electrode to concentrate weld current and forced between work to be welded.

Produce coalescence in one spot for heat generated from resistance to the electrical current through work piece held together under pressure by electrode. It process usually the thickness range. See all full list on amadamiyachi.

The process is used for joining sheet materials and uses shaped copper alloy electrodes to apply pressure and convey the electrical current through the workpieces.

Resistance welding is a process for fastening metallic objects together. The metallic objects have various electrical and thermal properties that make it possible for the resistance welding process to occur. Electrically, metallic objects have some level of resistance to the flow of electrical current. Idiots Tree Felling Fails with Chainsaw Machine - Tree Falls on Head and House - Duration: 8:11. In short, the spot welding process involves three stages.

In the first stage the electrodes are brought closer to the surface of the metal, a slight amount of pressure is applied to do so. The name “resistance” spot welding derives from the fact that the resistance of the workpieces and electrodes are used in combination or contrast to generate the heat at their interface. Amount of current that passes through the work piece. Pressure that the electrodes applied on the work piece. The time the current flow through the work piece.

The area of the electrode tip contact with the work piece. During the process , a spot welding machine is connected to a pair of tongs with two electrode tips that simultaneously clamp the sides of the joint together and deliver electric current to fuse the material and create the weld. More specifically, it tells the electrodes when to close and when to open, and it tells the welding current when to start and when to stop. The welding control may be thought of as the “brains” and the machine as the “muscle” of the overall resistance welding system. Tubes or sheets are accelerated by electromagnetic forces.

The oldest welding process in the world. Oxides must be removed by flux or flames.

High-frequency vibratory energy is applied to foils, thin metal sheets or plastics.
