[MW:4589] RE: Welding of Brasses & Bronzes


Hi Prem,
Good Day to you
The attachment you sent on welding of cast iron and copper alloys really is helpful for me. I will try to apply these concepts practically. I have also consulted the handbook of consumables manufacturers but unfortunately I did not get the required information. Kindly send me if you have any other material related to consumables selection event if it is about Stainless Steel. Also I would be very happy if I can help you in any kind of problem although I am a fresh metallurgical engineer having almost no experience in practical field.
Regards,
Uzzmaan

Hi Uzzmaan

Enclosed herewith is a small writeup (attachment) on Welding of Cast irons and Copper alloys which talks about selection of consumables.
Trust it will benefit you.

As you start working on these alloys you will gain more experience...

Also i suggest that you should refer Product Handbook of any Maintenance & Repair Consumable manufacturer for the selection of correct consumables / procedure for your application.
If you are in India then call me on my cell.

>Hi Prem

Many thanks for your reply. I have already consulted these documents.

But there is only a standard composition against each electrode coding

but unfortunately there is no selection criteria of electrodes for

Brasses,Bronzes and Cast Iron. For example in some applications we use

an electrode that gives the deposit of 60% Ni and rest of Fe for Cast

Iron Welding where as sometimes we use the electrode that gives 55% Ni

for the same kind of applications and sometimes we use an electrode

that gives 99.99% Ni. But I dont know the selection criteria. I mean

why dont we use an electrode that gives exactly the Cast Iron

composition. Same is the case with Brasses and Bronzes. I hope that I

have explained my problem.

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

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, ...

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

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...
