Welding filler metals inspections

Sampling. Weld filler metals packages or containers are usually 100% inspected, although the packages or containers must not be opened. 

Representative set of weldments was examined site welds (with pearlitic type weld metal) and two types of site weld repair zones with different welding technologies using Cr-Ni filler metals and Ni-based alloy. Results of AUGUR 4.2 inspection were compared with manual ultrasonic inspection ones in terms of defect detection, characterization, positioning and sizing in order to estimate correlation between these data. 

This alloy has satisfactory arc weldability (with filler metal 5356), and after welding, mechanical properties equivalent to those of the parent metal in the T4 temper can be achieved. However, it shows a strong sensitivity to exfoliation corrosion in the heat-afifected zone, on either side of the welding bead (See Section B.6.4.2 and Figure B.2.11). This handicap severely limits its use in welded structures to very specific applications that are subject to frequent inspection. 

The first 1 /8 in. on the process side is deposited by use of bare-wire filler metal and inert tungsten-arc welding techniques. The ferrite content of the deposit is controlled to minimize the possibility of cracking. This deposit is inspected visually and with penetrant. If the weld thus far contains...
