It is the intent of this publication to present current concepts and practices for resistance welding (and related processes) of ferrous and nonferrous metals including coated and dissimilar metals. Where practical, welding schedules are included. In other instances where schedules are too varied or the state-of-the-art is not sufficiently developed, descriptive guidelines are included to enable the user to establish welding procedures to meet its requirements.

It is important to recognize that these recommended practices are not the only means to weld the materials and thickness shown. When developing a welding schedule(s) for a particular application, the workpiece geometry, equipment employed, and production requirements will all influence the parameters and effectiveness of the process.

In using the data shown in the tables, it is imperative that reference be made to the appropriate text. Failure to refer to the text may result in misinterpretation of the data in the tables. The text has been kept as brief as possible and all extraneous comments have been omitted.

For more detailed information on the fundamentals of the resistance welding processes and the types of equipment utilized for the different processes, consult the current AWS Welding Handbook.

It is important to recognize that these recommended practices are not presented as the only conditions for welding the materials and thicknesses shown. Rather they are offered as a guide for setting up welding schedules for any particular fabrication, and may have to be modified according to the specific part conditions and production requirements.

This standard makes use of both the International System of Units (SI) and U.S. Customary Units. The measurements may not be exact equivalents; therefore, each system must be used independently of the other without combining in any way. The standard with the designation C1.1M:2000 uses SI units. The standard designation C1.1:2000 uses U.S. Customary Units. The latter are shown within parenthesis ( ) or in appropriate columns in tables and figures. An inch/millimeter conversion table is found in Table 59.
