Guidelines on the Welded Fabrication of Stainless Steel
Description

This resource is on CDROM and provides information, illustrations and images on the welded fabrication of stainless steels. It is aimed at welding experts who are familiar with carbon steels but wish to extend their knowledge to stainless. The program is divided into 7 sections: Corrosion, Stainless steel families, Principal welding processes (the various arc welding techniques), Behaviour during welding (including post-weld treatments), Joining of dissimilar steels, Weld preparation and different applications in construction and manufacturing and Examples of different weld qualities (MAG, tubular, TIG and Manual welding).

The Welding of Stainless Steel
Description

This resource is a paper describing how to weld stainless steels. Firstly it describes the chemical composition and mechanical properties associated with the different families of stainless steels. Then the majority of the paper concerns itself with ‘welding processes’, with the sub headings of ‘electric arc’, ‘resistance and induction’ and ‘radiation energy’ -  under each, the available techniques are illustrated and described. Following this, the weldability of each family, selection of shielding gases, selection of welding consumables, joint preparation in arc welding, finishing treatments and safe practices are covered.

Welding and Post Fabrication Cleaning for Construction and Architectural Applications
Description

This resource is a paper describing the issues of distortion during fabrication and welding, control of stainless steel welding processes and post fabrication cleaning. Buckling distortion can result from either poor design or welding practices. The key factors for good welding are clearly defined welding procedures (BS EN 1011 and BS EN 287 and BS EN 288 are mentioned), control of heat input, temperature control and cleanliness. Welding electrode selection and methods including TIG, MMA, FCA, plasma, submerged arc and stud welding are covered. Finally, the importance of careful heat tint removal (temper coloured areas) is discussed by either mechanical abrasion or chemical pickling cleaning methods. Although this establishes the corrosion resistance for the particular grade welded, care is needed with chemical pickling as it can change (dull) the aesthetic appearance of the surfaces.
