[MW:1175] TKY Joints defination and use of 6GR Welders

AWS D1.1/D1.1M :2006 para 2.24.1.5 (2) , attached, states that classification criteria of TKY joints is based on punching load cases of brace to chord connection.

Now the question is that:

The given weld connection is tubular to tubular (TKY type) but does not fall under TKY classification based on punching load cases as para 2.24.1.5.
for example secondary and miscellaneous small structures like access platforms , stairs  etc fabricated by tubulars/ pipes.
Do we need to treat these tubular to tubular joints as TKY joints and strictly welded by 6GR qualified welders??

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

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...
