Re: [MW:13917] Sample PQR fo CuNi Welding.

By Materials & Welding
For CuNi 90:10 material to CS /LAS you can use ER 90:10 CuNi , If it is of CuNi 970:30 metallurgy to CS You can use Monel ENiCu7 which is best compatable for discimilar metal joining

I need your valuable advice on following CuNi Welding, We have some joints in for Seal Strip, Material CuNi (B171-C46400). FYI, we don't have PQR and qualified welder to weld this joint in case welding activity done in our workshop. I need your help to get sample PQR for my reference, because I planning to qualified this PQR.  

Need your suggestions on this cases as given in these photos,

1)      To weld Sliding bar to tubesheet  as detail C

Material Specification:

Sliding Bar: A283 Gr.C

Tubesheet: A350-LF2 + B171 C46400 clad

2)     

BafBaffle plate to seal strip  as detail B.

  

mMaterial Specification:

Baffle plate: B171 C46400

Seal strip: B171 C46400

 

Your assistance is appreciated.

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...
