Resistance welding and energy storage spot welding

What is resistance spot welding?

By concentrating the heat and pressure at specific points, resistance spot welding creates strong and durable bonds, making it an ideal choice for applications that require high structural integrity. The process of resistance spot welding involves the use of specialized equipment, including welding electrodes and a power supply.

What are the limitations of resistance spot welding?

RSW also suffers from a few limitations like liquation cracking, voids, misalignment, electrode wear, etc. Thicker sheets of metals are generally difficult to weld by RSW because the heat flows into the surrounding metal very easily. 2. Principles of resistance spot welding

What are the components of a resistance spot welding system?

The primary components of a resistance spot welding system include welding electrodes, a power supply, and a control unit. The welding electrodes, typically made of copper alloys, apply pressure to the metal sheets and conduct the electrical current necessary for generating heat at the welding points.

What are the different types of resistance spot welding techniques?

The techniques included the use of double-pulse welding current and various metallic or non-metallic interlayers. Also, the broad field of applications of resistance spot welding was mentioned, and also a modified RSW technique which is the projection welding was also elaborated in this chapter.

What are the advantages and disadvantages of resistance spot welding?

Resistance spot welding offers several advantages, such as high production rates, minimal need for filler materials, and the ability to weld various metals, including steel, aluminum, and stainless steel. However, it also presents some limitations, including restricted accessibility for complex joint geometries and the potential for electrode wear.

What is resistance welding?

The process of resistance welding involves several key steps that contribute to the successful fusion of metal sheets. It begins with the preparation of the metal surfaces to be welded, ensuring that they are clean and free from contaminants that could affect the quality of the weld.
