Burn Through in your case I understand was caused with the hot pass.

 

It is caused by electrode diameter or excessive power, thin root, poor handling of electrode, large root gap before root pass, position of job.

 

Not knowing your electrode travel direction I advise you as follows.

 

E6010 produces a strong weld. However to minimise burn through situations, I would recommend a second pass with E6010 on vertical down travel to thicken the root, or, vertical up travel with a smaller E7018 electrode, or, weld a separate plate/pipe with the parameters that is most suitable for you, or, run a welding procedure for anyone to follow.

 

Hope it helps

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...
