Refractory electrode materials, such as tungsten/copper, tungsten, or molybdenum are used for applications such as projection welding inserts, where the electrode contact area is at least three times the weld size. These materials have higher hardness but lower conductivity than the Class 2 electrodes.

Spot welding (also known as resistance spot welding) is a resistance welding process. This welding process is used primarily for welding two or more metal sheets together by applying pressure and heat from an electric current to the weld area.

Hold time is the period of time programmed into the weld controller, typically between the end of weld time and the command to open the electrode. The actual hold time is the amount of time for which the electrode force is applied after current ceases to flow.

Electrode sticking to the work piece generally is caused by excessive heating between the electrode and the work piece. In the Relative Resistivity Diagram RC has become too large. Any factor which would cause this is an issue that must be addressed to prevent this manufacturing problem.

Tips to avoid welding rod sticking to the metal

1. Choose the correct current settings.
2. Keep the electrode and surface clean while using the correct rod size.
3. Try to keep a good ground connection.
4. Follow the correct arc striking technique.
5. Use an appropriate arc Length.

Arc Length Too Long Arc welding is a constant current process, but the arc length has an effect on voltage. Reducing the arc length will decrease the voltage, and this reduces the heat in the weld. Increasing arc length will increase the voltage.

The weld bead is wide with excessive spatter and undercut. Travel speed is influenced by the type of welding current (DCEN, DCEP or AC), amperage, welding position, electrode melt rate, material thickness, surface condition of the base metal, type of joint, joint fit up and electrode manipulation./span>

Welding arc temperature usually ranges between 6000-8000 degrees Celcius which converted to Fahrenheit would be roughly between degrees, but the exact temperature depends on a lot of factors like the current type, shielding gas type, amperage, etc.

Yes, you can get shocked welding! Receiving a mild shock on occasion while rare does happen. Receiving an injurious or fatal shock is even rarer. But our goal is to make sure that you never receive a shock of any kind!
