The main feature is the addition of iron powder in E7018.

 Hello

I am having a PQR qualified with E7018 electrode , and corresponding WPS there by, now i need to qualify some welders for that i need E7016 root and E7018 hot,fill and cap. So i am not changing the essential variables, so is it possible for me to use the same WPS for qualification. can anyone help me in this?

Regards

Anish

Dear Sil,


Both are Basic type, low hydrogen rods and having similar strength, but E7016 is without the iron powder in flux.


E7016 :Low hydrogen potassium Electrode ( not BASIC SODIUM LOW HYDROGEN; E7015 is Low hydrogen sodium electrode)

E7016's have less slag than E7018's so are better for root-run, positional welding (better controlled positionally) than E7018, easy deslagging and baking/redry not required

 

E7018 :Low hydrogen potassium, iron powder Electrode

E7018 has iron powder added to the flux, which goes into the weld-pool when the rod is burned, so more metal is deposited. Baking/redry required.

 

Both electrodes having F no. 4. You can use E7018 instead of E7016, here essential variable (F no.) not changed, but re-write your WPS accordingly.

Dear sir,
What is the quality wise difference between E-7018 ( BASIC LOW HYDROGEN) & E-7016 ( BASIC SODIUM LOW HYDROGEN).Can i use E-7018 insted of E-7016.
Where is the specific area of these two electrode
regards
sil

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...

Re: [MW:10788] ON PLOT PIPING & OFF PLOT PIPING

By Materials & Welding
Piping systems involved for the flow lines and gathering lines from the well head isolation valve to the production facility or processing plant isolation valve are determined as OFF PLOT. ON PLOT defines piping system in the processing plant and production platform. ANSI/ASME B31.4 applies for off plot piping system. B31.4 allows the use of either API 1104 or ASME section IX (as appropriate). However, occasionally, a very small system such as piping within 500 feet of a processing plant (some client also said 400 feet) may be declared B31.3 rather than B31.4. When B31.3 is invoked, only ASME Section IX is used. before you decide which code to use for welding procedure and/or welder qualification for pipe welding, you have to know the design and construction code applicable to the system. Please read far enough into scope and diagram illustrating the application of either B31.3 and B31.4 hope this helps rgds 2011/4/21 pradip kumar sil < pradipsil@gmail.com > Dear all, ...
