Hi, may I ask those of you who have knowledge and where one can buy welding balloon for small bore GTAW welding down to 1/2 "stainless pipe ID. We can get them in Norway but not less than designed for 2" tube only.

Hi,
Question 1.If a weld qualifcation is conducted with welding process 136 (FCAW) is it allowed to prepare out a WPS with welding process 138?
Question 2. A PQR of a fillet weld is made with HI 1,0 kJ/mm and hardness testing is completed as pr ASME IX, is it allowed to specify higher HI than...
We have performed a PQR of a 45mm plate in S355 material and weld position 3G. Welding method is FCAW. The number of single welding layer is 50 pcs achieved during the PQR welding.
Please may someone state which of the calculation methods are most appropriate when observed heat input values to...
Hi
Have any of you heard about if it is defined in any codes or standards whether it is possible to use two WPQR's to support a WPS for small bore tube welding in super duplex provided that all essential parameters in both WPQR's are equal but that each of WPQR's have different wall thicknesses...
Hi,
I work as a welding engineer in Aker Solutions Norway Umbilical Dep. and wonder if anyone has experience in GTAW welding of pipes in API 5L X65 material without subsequent local heat treatment (PWHT).
The actual dimension is OD 150mm and wall thikness 8mm and looking for good and feasible...
