Re: [MW:34220] Parent material Thickness For GTAW process

By Materials & Welding
pl correct the following--- ASME SEC IX is not a Construction code, it is Reference code.
Since ur base metal thickness is 11mm, Qualification range for GTAW of Base metal is 5mm to 22mm

Dear All,


We have prequalified WPS of combination  GTAW+SMAW

 

Qualified material :4"  Dai X Sch-120(11.02mm)

Garde : ASTM A106 GR B

Welding Process :  GTAW +SMAW


Construction Code : ASME SEC IX

 

Root/ Hot : ER70S-6 Dai 2.4

Fill 1,2 ,3 : E7018 Dai 3.2

Cap           : E7018 Dai 2.5.

 

With Above WPS I would like to extract new WPS for GTAW Process. Please Kindly confirm  what shall be the range  for GTAW process  for parent material thickness . Kindly advice. with reasoning.

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...
