Re: [MW:7214] use of E 7018 Electrode for stuructural welding without proper drying and holding

By Materials & Welding
Dear Azad..
 
Baking & drying is required for the basic electrodes like E 7018 to reduce the hydrogen content in the deposited weld metal. If you are not doing any baking there by you are improving the condition for hydrogen cracking the weld metal.
 
You have mentioned that you are using E 7018 for the angle bar welding .. normally for structural purpose you can proceed with rutile electrodes like  E 6013 which needs to be dried only.
 
best regards,

Dear All,
 
Goodday.
 
 
what will be the effect in Mechanical/chemical proerties of deposited weld metal of  E7018 which is used for Structural welding of angle bar( material CS) without drying  (at 260-430deg C) and Holinding(at 120 deg C).
 
 
Can E7018 be used without proper drying and holding for stuructural welding( fillet weld only) of angle bar/supports(material CS).
 
 
Thanks in advance for your valuable suggestions.
 
Best  Regards

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...
