To weld SS 316 you should use matching SS consumable. It it is not a "L" grade material like SS 316L , you can use E316 for SMAW / ER 316 for GAW , & if the base material is "L" grade like SS 316L, you have to use E316L or ER316L, but even in both the cases you can use E316L / ER316L consumable. Pre-heating & PWHT is not required for Austenetic Stainless steel ( SS 316 ). But if your working place is full of moisture or in rain condition, you can apply heat just to remove the moisture from the surface of the joint to be welded.   Regards, On Mon, Jun 29, 2009 at 12:27 PM, sandy kumar < sandy001987@gmail.com > wrote: Can any one tell me how to weld SS 316 to SS316 ? -- Sukamal Naskar Malaysia --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to materials-welding@googlegroups.com To unsubscribe from this group, send email to materials-welding-unsubscribe@googlegroups.com For more options, visit this gr...

These steels are produced with accelerated/controlled cooling to get the improved mechanical properties, particularly toughness. due to this inherent charecterstic of TMCP process, these can't be formed at elevated temperatures. check the link for more info about the process. http://www.leonghuat.com/articles/Thermomechanical%20Control%20Process.htm ASME SA 841 is TMCP steel On Jun 27, 3:35 pm, Arjan van Vessum < vess_kiw...@hotmail.com > wrote: > >580 degrees its mechanical properties can/will decrease > > Date: Thu, 25 Jun 2009 04:30:36 -0700 > From: asghari...@rocketmail.com > Subject: [MW:2547] thermo mechanical steel > To: materials-welding@googlegroups.com > > hi > why isn't allowed heat treating in the range(590+/- 10) for TM (THERMO MECHANICAL) STEEAL? > rjd. > > _________________________________________________________________ > Nieuws, entertainment en de laatste roddels.

Dear Sir, We are having some difficulty in coming to common grounds with our customer on interpretation of ASME Section 9 qualification requirements for Copper to Copper lap joint with filler metal. I will try to explain you the entire case for your perusal and advice. We are in the business of large motors for cement plants, generators and similar applications. The customer asks for qualification of operators in welding and brazing as per ASME section 9. The entire details of the joint are as attached in the document. As per our interpretation of code the code asks for Tension test, Peel test and Section test. We get the tests done in approved authorised laboratories. In all the tests the trend is such that the brazing coupons are passing in tensile tests and sectioning tests. But the Peel test coupons does not have consistency in qualifying as per norms. As per the qualification criteria the test are basically visual inspection and have some inbuilt subjectivity hence the di...

None, yes its forever as long as it represents your production weld. However changes may be made in the nonessential variables of a WPS to suit production requirements without requalification provided such changes are documented with respect to the essential, nonessential, and, when required, supplementary essential variables for each process. This may be by amendment to the WPS or by use of a new WPS. Changes in essential or supplementary essential (when required) variables require requalification of the WPS (new or additional PQRs to support the change in essential or supplementary essential variables).

Yes, The paint inspection courses conducted by SSPC or NACE are honoured in Gulf countries but I would suggest to go for NACE as it is more evolved.

Dear sir,   I am talking for the product of hydro-power plant area, The component has got bowl kind of shape.The size of the component is 6 meter diameter & 4 meter in height.   The design has asked to check with 100% U.T. & in addition to this, needs to be check for water tightness.   So for such a big size component, filling of water is not feasible, so does ASME codes has any provision to check for water tightness except to fill with water   Hydro test also can not be done.
