Q: The Maximum Interpass temperature recorded on my BS EN ISO 15614-1 WPQR (S355 Carbon Steel MAG Butt Weld in Plate) is 229°C. Surely the welding Inspector has made a mistake...everyone knows it should be 250°C?
Q: In accordance with the Ultrasonic Testing of Welds Specification BS EN ISO 17640:2010, which of the following statements is true?

B - Thickness's ?8mm can only be tested on Welds.

Q: If you had a Fillet Weld with 20mm Leg Lengths what should your Throat Thickness be?
A: C- 14mm
The conversion to calculate what your Throat Thickness should be is 0.7 X your actual leg length, for example 0.7 x 20mm = 14mm.
Q: I've been told that if I weld a 30mm thick fillet weld for a BS EN 287-1 test I will get a range of approval of 5mm and above, is this the best test to take?
A: Not quite, BS EN 287-1 gives you a range of approval of 3mm and above for any fillet weld test piece thickness over 3mm. It sounds like there is some confusion with another standard that offers a similar range of approval but references welding procedure qualifications, not welder qualifications.
