Method for the projection welding of high-carbon steels and high-tension low-alloy steels |
摘要 |
This invention provides an improved method of projection welding which enables the sound welding of high-carbon, and high-tension low-alloy steels. A spacer is disposed between two parts to be joined by projection welding. At least one of the parts is made of a high-carbon, or high-tension low-alloy steel. The spacer is a thin sheet, or coating formed on at least one of those parts.
