本文件规定了浮雕投影焊接用投影的几何形状和尺寸。进行预测的工具也包括在附件B中。 这些凸出物用于热轧、冷轧、无涂层和涂层钢、不锈钢和镍合金，用于厚度不超过3毫米的常规焊接质量，可以是单个凸出物、多个凸出物或一组凸出物。 本文件不包括任何实体投影。

This document specifies the geometries and dimensions of projections for embossed projection welding. Tools to make the projections are also included in Annex？B. The projections are used on hot-rolled, cold-rolled, uncoated and coated steels, stainless steels and nickel alloys for conventional welding quality up to 3？mm thickness, as single projections, in multiples or as a group of multiples. Any solid projections are not included in this document.
