Re: [MW:35289] Welding consumable for S355J2WP material

S355 J2 WP  is a weathering structural steel  It has better atmospheric corrosion resistance.

As per table 5 in ISO 15614 we can use it. But I have a concern I have to use filler material with different chemical and Mechanical property (Cl.8.4.4) like instead of ER80S-B2 I will use ER90S-B3.

[MW:35297] HIGH THICKNESS (80-120MM) PRESSURE VESSEL FABRICATION

Dear team, We got an order for 120 mm the carbon steel pressure vessel from our customer. Is there any special care to follow during fabrication. It will be very helpful if anybody could share a procedure for high wall thick pressure vessel fabrication. I have no experience of high wall thick PV fabrication.  Thanks in advance for your expert opinion.

[MW:35298] RF pad requirement

Dear Experts I have a question regarding the RF pad design. If a vessel's RF pad is designed as a full RF pad but is facing fabrication issues such as the welding not being allowed to touch and potential concerns with bolt placement, how does that impact our calculations? Specifically, if the cutting portion of the RF pad is affected, do we need to recalculate the entire design calculations for that RF pad? Thanks in advance for your expert opinion.

[MW:35300] Re: SA335 P91 to SA106Gr.B Dissimilar Material Welding Procedure

this could be part of improper design or RF Pad support welding(fillet)?  and this question already earlier answered in the group. this kind of joint can be further welded or joint by weld flange at each and then bolted with insulated bolt.,  however service temperature variation may affect both joint thermal expansion that need to add by metal expansion joint at CS side. pl do not joint directly by welding. Or else use transition spool as mentioned above if you have multiple WPS's/PQR's to support these welding.

[MW:35306] Re: SA 387 Grade 22 Cl.2 - Welding Crack

Hi Dear You should do DHT operation immediately after finishing the welding process post heating is to minimize the susceptibility to cold cracking due to residual hydrogen in the welds and to minimize problems due to low as-welded toughness. Because of hydrogen pick up during the welding process, a dehydrogenation heat treatment is applied to the weld to outgas the hydrogen before a weld allowed to cool. DHT will be started at 300 C within a minimum 200 mm band with weld in the center line promptly at the first strike of arc and will be finished minimum 2 hours after taking the strike off the base metal.
