Mr. JIBIN PHILIP,
THIS S275JR IS A STRUCTURAL NON ALLOY STEEL EQUIVALENT OF IS2062.
HOW EVER IN ANY WELDING HEAT INPUT IS ALWAYS CONTROLED THROUGH WPS
BY WAY OF TRAVEL SPEED. THE FORMULA FOR HEAT INPUT IS (v*a) / travel speed.
ANOTHER FACTOR TO REDUCE THE HEAT IN PUT IS TO PREHEAT THE JOB.
Thanks/Regards,

Welding Process - FCAW ( E71T-1C )
Filler Size - 1.2mm
Material - S275JR to S275JR
For Demand Critical weld as per AWS D1.8, is there any heat Input restrictions are to be followed or not??. In our current WPS the Heat input mentioned are 0.6 to 1 kj/mm.Is this acceptable for Demand Critical weld application ??. In AWS D1.8 - clause 6.8.1 mentioned as " The heat input range qualified by testing in accordance with Annex A. In annex A it showing a range of 1.2 to 3.1 kj/mm. Dear Experts please help .
