Re: [MW:11745] Required procedure of Tackers qualification ....

Hi,
AWS requires Tack welder's qualification.Please find below the extraction from AWS.Also please refer Table-4.12 for Essential variables for Tack welder's qualification.

4.1.3.2 Tack Welders. A tack welder who passes the

test described in Part C or those tests required for welder

qualification shall be considered eligible to perform tack

welding indefinitely in the positions and with the process

for which the tack welder is qualified unless there is

some specific reason to question the tack welder's ability

(see 4.32.2).

4.18.1.2 Tack Welders. A tack welder shall be qualified

by one test plate in each position in which the tack

welding is to be performed.

4.19.2 Tack Welders. The tack welder shall make a

1/4 in. [6 mm] maximum size tack weld approximately

2 in. [50 mm] long on the fillet-weld-break specimen as

shown in Figure 4.39.

4.19.2.1 Extent of Qualification. A tack welder who

passes the fillet weld break test shall be qualified to

tack weld all types of joints (except CJP groove welds,

welded from one side without backing; e.g., butt joints and

T-, Y-, and K-connections) for the process and in the position

in which the tack welder is qualified. Tack welds in

the foregoing exception shall be performed by welders

fully qualified for the process and in the position in which

the welding is to be done.

Thanks & Regards,

Hii Experts ...

Kindly provide the details of procedure of Tackers qualification ....how to qualify ? what is the procedure of it ....?

Thank you for your time

Re: [MW:34105] SA266 GR4N 4 Cycle SPWHT

Hi, You are correct, Minimum refers to the one cycle for which this part will expose until final work shop PWHT. hence mill test certificate shall include this. Max. SPWHT, refers to additional cycles of heat treatment that are reserved for future repairs during equipment lifetime. Again, these simulated no. Of cycles shall be specified in MTC. The idea is we need to make sure that steel mechanical properties are not compromised upon exposure to multiple repairs (i e 4 cycles in your case). One could say, if steel is subjected to 4 cycles and is ok, then it should by defacto be good for one cycle, yet, this is wrong assumption cause mechanical problems and microstructure of materials varies accordingly based on no. Of cycles for which material will expose. This is apparent in alloy steel and especially for impact test values as an example. In your case, this forged CS with properties before PWHT can be understood to be " as forged" condition (i.e. Wit...

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...
