Existing steel structures and plant may need welded modifications or repairs. They may have been designed and built to withdrawn/superseded Standard specifications. In some cases the design and fabrication records may not be available. This paper reviews past UK welding specifications so as to provide guidance on the approaches which can be made to assessing the suitability of an old structure for welding. A list of withdrawn/superseded British Standards, forms an Appendix to this article.
