Re: [MW:22950] SUITABLE ELECTRODE FOR S355 J2W CORTEN STEEL

By Materials & Welding
When welding Corten the precautions are similar to mild steel except that you may need
a special filler material to produce the weathering steel weld. (6013s are not acceptable.)
  • If the plate is 10mm thick or less, and the weld is a single pass (eg a fillet weld), 
    you can use an E7018 or SG2 MIG wire. This is because you will get enough dilution 
    from the plate to render the weld weathering.
  • If it's greater than 10mm thick or a multi-pass weld you need to use a filler containing 
    approximately 1% Nickel and 0.5% Copper (otherwise mild steel), or one containing 
    2.5% Nickel (otherwise mild steel).
This will result in a weld which will "weather" like the plate.
E 8018-C1, E 8018NiCuCr are also recommended for welding Corten steels.

Hence it is easy to make WPS

Dear Experts,

We need to qualify a PQR for S355 J2W Corten Steel Plates and I request you to suggest a suitable electrode and provide me a PWPS for S355 J2W.

Thanks in advance.

Sincerely,
Vijay

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...

The Schaeffler and Delong diagrams for predicting ferrite levels in austenitic stainless steel welds

By Materials & Welding
Introduction Ferrite is important in avoiding hot cracking in during cooling from welding of austenitic stainless steels. 'Constitution diagrams' are used to predict ferrite levels from the composition by comparing the effects of austenite and ferrite stabilising elements. The Schaeffler and Delong diagrams are the original methods of predicting the phase balances in austenitic stainless steel welds. Nickel and chromium equivalents A 'nickel equivalent' is calculated for the austenite stabilising elements and a 'chromium equivalent' ferrite stabilising elements. These are used as the axes for the diagrams, which show the compositional equivalent areas where the phases austenite, ferrite, martensite (and mixtures of these) should be present. Although intended to show the phase balance of weld fillers, these diagrams can also be used to illustrate the phase balance of the 'parent' material. There are different diagrams for dif...
