By Materials & Welding
REFER THIS ALSO As per ASME B31.4

434.8.4 Welding Standards. All the welding done
under this Code shall be performed under a specification
that embodies the minimum requirements of this Code
and shall encompass the requirements of API 1104
except as provided in paras. 434.8.3(a) and (b).
434.8.3 Welder and Welding Procedure
Qualifications
(a) Welder and welding procedure qualifications for
cross-country pipelines shall be performed in accordance
with API 1104. Welder and welding procedure
qualifications for alloy steel and for shop fabricated piping
assemblies, and welding at stations and terminals
shall be performed in accordance with API 1104 or
Section IX of the ASME Boiler and Pressure Vessel Code.
(b) Prior to anywelding covered by this Code, awelding
procedure specification shall be established and
qualified by testing to demonstrate that welds having
suitable mechanical properties and soundness can be
produced. Welding procedure specifications shall be
qualified as required by API 1104, or Section IX of the
ASME Boiler and Pressure Vessel Code, whichever is
appropriate for the locations, materials, and type of
welding to be performed except as modified by the
following

Dear all

for welder qualification can we use sec IX instead of 1104 for cross country pipelines.

if no ,what is the issue behind?

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...
