[MW:3330] Re: Painting

By Materials & Welding
Hi Saravanan,

Please verify and check the following.

1. Check the amount of solvent for final coating.
2.Verify the over coating interval as per the paint manufacturer.
3.Check the mixing of coating materials.( for 5gal and above required mech stirrer).
4. Check the surface condistion of the base metal.

These are the probable reason, which may i am thinking. If the problem still exist, get the advice from paint manufacturer.

Regards,
M.R.Pramodh

Dear Guys!!!!!!!
 
The project which I am involved following the paint systems as per client spec follows:-
 
Inorganic Zinc(75-100 micron) as a primer
High Build Epoxy(100-150 micron) as a Intermediate
High Solid Aliphatic Polyurethane(40-100 micron) as a finish
 
Total Dft between (215-350 micron)
 
After the complete curing of the finish coat visually I observed tiny pinholes like appearance or fish eye only inspector eye can find them.
 
Please give me the suggestion where the problem from? this appear in almost all the painted works which applied many different days, different paint batch followed by airlesspray method.

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...
