I agree with you, i think that need to improve the preheat and heat imput

Dear All,
I need help
we performed a butt weld ( full penetration ) qualification with the following characteristics:
ASTM A350-LF2 to ASTM A333 GR.6
Thickness of pipe 5,54 [mm]
Diameter of Test Coupon 60,30 [mm]( 2 inc )
Welding Process(es) GTAW
Poition 6G
Amps. 100 to 130
Volts 15 to 16...
A well-known supplier of welded load ring, claims to supply an S355J2+N with impact test at -45. shouldn't he call it S355J4 / J5?
Can S355 reach these temperatures?
Thanks in advance for your answers
thanks for the reply, I did not specify that I am in the QW-403.6 impact test regime (The minimum base metal thickness qualified
is the thickness of the test coupon T or 5/8 in.)(16 mm),. Actually I wanted to qualify higher thicknesses, and the QW 202.4 says that with MB greater than 38mm the...
I have to weld a T-joint in full penetration with dissimilar thicknesses in Asme IX. Both materials are in carbon steel (P-N.1.2) the only QW that speaks of dissimilar thicknesses is QW-202.4.
Base material 1 thickness 8mm
Base material 2 thickness 35mm
the QW-202.4 for the CS refers to the...
