Re: [MW:14058] crack in weld during fillet welding in E-450 grade plate

By Materials & Welding
Pawan,

See CE equation below, it is e.g. in EN 1011-2 standard. If you check and recalculate the CE according to the chemical compositions in the TC, the CE is 0,53 and 0,51 (instead of 0,47).

I suggest you to see this site: http://www.axoncalc.com/weld_preheat_calc.php, and you can check CE (Pcm), and get the preheat and interpass temperature.

Dear Pawan,

Have u observed any distortion after welding? if yes,I think u have to
change SAW process to GMAW/SMAW .When u r welding on one side,other
side fillet weld may get cracked and this is due to sudden
soldification of high volume molten metal.

I am not sure about this and u may go with expert advice.

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...
