In mild steel, carbon is the alloy material, while for stainless steel, you will find chromium. However, the chromium in the structure of stainless steel is responsible for it is high resistance to corrosion. Additionally, the surface doesn’t get stained or tarnishes.
Archaeology
- Enquiries are often received about welding wrought iron; for example, information is sought on repairing structures built as long ago as the middle of the 19th century.
Exhibitions
- Notable examples are the Palm House at Kew Gardens, restored under the direction of Posford Pavry and Partners, and the G-MEX Exhibition Centre in Manchester.
Benefits
- Rolling or hammering applied to the iron after it comes out of the furnace elongates the slag particles to form stringers which, for good weldability, should be low in volume - preferably with low width or depth, i.e. they should be more or less one-dimensional.
Preservation
- Small quantities of reclaimed wrought iron are occasionally available for use in restoration work. There is therefore a need to weld wrought iron either to itself or to mild steel.
Variations
- This is possible using manual metal arc or shielded metal arc (MMA or SMAW)) welding with rutile-coated electrodes complying with BS EN 499 E38 X R XX or AWS E6013, or by MAG (GMAW) welding with a filler wire complying with BS EN440: G2Si or G3Si, or AWS ER 70S-2.
Construction
- Because of the high oxygen content of wrought iron, the MAG (GMAW) welding filler wires recommended contain aluminium as well as silicon and manganese as de-oxidisers, and there is some evidence that this gives sounder welds than other filler wires. However, results also depend on the quality of the wrought iron being welded, and weld tests using samples of the actual iron …
Use
- Rutile electrodes are chosen for MMA (SMAW) welding because of their low penetration and their ease of use for positional welding, and the lower tensile properties reduce the stress on the heat affected zone (HAZ).
Advantages
- High-quality wrought iron, i.e. with low carbon and sulphur content and well-distributed slag stringers, gives fewer problems in welding. However, while the chemical composition may suggest good weldability, it will give no indication of the distribution or the volume of slag; this will be revealed only by microsections. It should be bourn in mind that due to the manufacturing met…
Locations
- Again, microsections should be obtained wherever possible before welding. A welding procedure test should be carried out if a large enough sample can be obtained.
Prevention
- Techniques to reduce shrinkage stresses due to welding should also be adopted. These could include the use of stringer beads, buttering of the wrought iron prior to completing the structural weld, keeping the weld preparation to a minimum, back-stepping and cooling-out between runs.
Significance
- It must be recognised that the microstructure of wrought iron may mean that volumetric non-destructive examination of the welds is difficult. It is, therefore, important that structural repairs are only undertaken if there is a high probability of sound welds being produced.
Safety
- An additional problem frequently encountered when repairing old structures, whether they be wrought iron or steel, is the presence of lead oxide based paints. To reduce the risk of welders breathing lead fume, these coatings should be fully removed prior to any welding repair being undertaken. This must be done with due regard to health & safety issues. Tests carried out by T…
