How are spot weld nuggets measured?

This is frequently done with a combination of a hammer, pliers and a chisel. The resulting pulled weld nugget is then measured with a set of calipers in two directions, 90 degrees apart. The two numbers are added together and divided by two for an average.

How are spot weld nuggets measured?

What is pulse in spot welding?

Some resistance spot welding power supplies employ a dual pulse spot welding feature which allows the use of two pulses to make a weld. The first pulse is generally used to displace surface oxides and plating, and the second pulse welds the base materials. This feature also reduces spitting.

How does spot welding work?

Spot welding works by applying pressure and heat to the weld area using copper alloy electrodes. These electrodes transport an electrical current through the weld segments. As the material melts the parts are fused. At this point, the current is turned off and pressure from the electrodes is upheld.

How do you set spot welding parameters?

Diameter of the electrode contact surface should be slightly larger than the nugget diameter. For example, spot welding two sheets of 1 mm thickness would require an electrode with a contact diameter of 6 mm. In practice, an electrode with a contact diameter of 6 mm is standard for sheet thickness of 0.5 to 1.25 mm.
