[MW:35598] Dish end manufacturing l docs required

Dear Experts,

I recently installed a 300-ton hydraulic press for bending dish ends for vessels and storage tanks. Could you please advise on the necessary documents and certifications that our company may be required to provide? Specifically, I'm interested in knowing about WPS (Welding Procedure Specification) and PQR (Procedure Qualification Record) requirements.

Additionally, what technical data or questions can buyers typically ask for in this industry before placing any dish end orders?

Thank you for your guidance.

Best regards,

Rockey

Re: [MW:35547] WELDING OF SS 310 MATERIAL CRACK ISUUE..

Dear Mr. Praveen,

Try with following guidelines if possible.

1.Control heat input (1 to 1.5 kJ/mm) and interpass temperature (100–150°C).

2.Consider using ER309L or ER310L filler metals instead of ER310.

3. Use TIG or pulsed MIG welding with proper technique.

4. Ensure clean base metal and proper joint design to reduce restraint.

5. Use Stringer beads over weaving to reduce heat input and distortion.

6. If cracking persists, use nickel-based fillers (Inconel 600, 625) for high-temperature service.

Hope above info. will help to get defect free welds.

C Sridhar.

Re: [MW:35551] WELDING OF SS 310 MATERIAL CRACK ISUUE..

I also faced the same, it was centerline cracks in Single bevel joints :

Primary reason is Zero delta ferrite for these welds.

Suggest the following measures to avoid cracking:

- Low Heat input with Low Interpass

- Increased Mn content in the filler on the higher side

- Use of SMAW lowers the risk of Cracking than GTAW if 310 filler is mentioned in the specifications

- Use of 309 fillers.

Hope, this will resolve your cracking problem.

Pratik U. Gandhi

one more point to add.

Check welding consumable manufacturer's supplying ER 310Mo with Manganese on higher range

In addition to cn Sridhar sir's recommendation following points to be considered.

ER310Mo produces a Nil Delta Ferrite weld since it is used at High Temperatures and prone to Hot Cracking.

Please share the photograph of the crack with location to determine the type of crack such as Hot cracking, IGC (intergranular corrosion) etc..

Solidification cracking (hot cracking) is also known as centerline cracking as it occurs in the weld centerline. Can be prevented by below methods.

1. Normally in Austenitic stainless steel a Delta ferrite content of 3-8% is recommended to prevent Hot cracking but ER310Mo is a Nil deltaferrite weld and prone to Hot cracking.

2. Reducing the impurity contents in the electrode such as sulphur and phosporous to a very low level.

3. Restricting the Interpass temperature to a maximum of 100degC as it will enhance fast cooling and reduce the time spent between the liquidus and solidus curve during the final stages of solidication.

4. The same effect is attained by restricting the Heat Input to a reasonable level.

5. By maintaining proper weld bead width to depth ratio, Normally a ratio of 1:1 is recommended and maximum recommended is 2:1 and beyond which Hot cracking will occur.

Please share a photograph of the crack to understand its nature.

Thanks & Regards

Re: [MW:35552] WELDING OF SS 310 MATERIAL CRACK ISUUE..

It is fissuring due to fully Austenitic structure and delta Ferrite is less than 5. Control the heat input by using minimum bearable amps. Use DM water on weld behind the weldmetal to make cool fast. Otherwise, if project permitted, u can use 309 to avoid fissure
