It's essential in automobile body production to perform resistance welding, including nut and bolt, spot, and stud welding. Thousands of spot welds support the quality and reliability of an automobile's body structure. Technology continues to progress for preventing rusk, along with making the auto body's structure lighter and stronger, through better materials. The demand for thin-coated steel has been steadily increasing for the past 20 years. Recently, the demand for hlgh-tension material with rust-preventive coating has inceased. Although there have been improvements to these materials, many new obstacles have arisen in spot welding. This article is not intended to tell you how to weld this new materials, but rather to explain the changing of electrode management when using these materials to achive better welding quality. The importance of electrode management in modern body shops is at in alltime high. The uncertain climate that manufacturers are in today cause many engineers to look for ways to save money without risking quality. Tip dressing is important and necessary because it helps improve economic impacts and provides better welding quality across the automotive manufacturing board. With the new technology previously mentioned, it's felt that tip dressing will be something every automobile manufacturer will have in the near future, and it will dramatically impact costs as well as the environment for years to come.
