Is spot welding better than soldering?

A spot welded connection generates less heat and makes a more secure bond than soldering does. Of course, it also depends on the quality of the weld; spot welding CAN generate enough heat in a specific area to generate a hole in the cell that can cause major problems down the road.

How many volts are needed to spot weld?

Spot welder voltage is usually set between 5 to 22 volts, the electric current usually ranges between 1000 to 10,000 amperes. Industrial grade spot welding machines typically use three-phase electric power to reach high peak currents in manufacturing.

How thick can a spot welder weld?

Spot welding is primarily used for joining parts that are normally up to 3 mm in thickness. Thickness of the parts to be welded should be equal or the ratio of thickness should be less than 3:1. The strength of the joint depends on the number and size of the welds. Spot-weld diameters range from 3 mm to 12.5 mm.

How long does it take to weld one spot?

Spot welding is also a fast welding process. According to Wikipedia, the average weld time for spot welding is just 0.01 to 0.63 seconds. Like with other welding processes, the weld time varies depending on the thickness of the workpieces. Thicker workpieces tend to have a longer weld time than thinner workpieces.

What are the disadvantages of spot welding?

How does a battery spot welder work?

A spot welder works by releasing a pulse (or two) of high current through two leads. The leads should be touching the material, let's assume Nickel, to be welded. The high current heats up the Nickel beyond it's melting point and once cooled, the metal surfaces are welded together.

Can stainless steel be spot welded?

Spot welding is a popular way of joining two sheets of thin metal, such as stainless steel. The sheets are placed between the two welding electrodes, to which pressure is applied.
