Dears,   Could you advise with code ref or guidlines. Construction codes: ASME B31.1 & I sections. What's the tolerance for piping slope ?

Can you give code reference for the formula ? Never seen it in ASME Sec VIII Div.1 or 2.

The M designator is a "Mandatory Classification Designator" that indicates that the electrode meets the US military requirements (MIL Spec.)– see ASME Section II Part C, SFA-5.1 figure 10.  These are more stringent than typical commercial requirements.  The Level 1 indicates the testing level within the applicable MIL Spec. See the following.   Hope this helps/answers your question.   From SFA 5.1 Annex A:   A7.6.8 E7018M [E4918M] Classification   A7.6.8.1 E7018M [E4918M] electrodes are similar to E7018-1H4R [E4918-1H4R] electrodes, except that the testing for mechanical properties and for classification is done on a groove weld that has a 60° included angle and, for electrodes up to 5/32 in [4.0 mm], welded in the vertical position with upward progression. The impact test results are evaluated using all five test values and higher values are required at –20°F [–30°C]. The maximum allowable moisture in-coating values in the "as-recei...

Please refer below about your query.  Well Explain by Mr. Goswami   Nickel in C-Mn steel increases the acicular ferrite. Usually ferrite in C-Mn steel, which is usually soft is polygonal ferrite. Increase of acicular ferrite causes increase of UTS, impact strength and at the same time hardness also. The last one(hardness control) is  the topmost priority in Sour Service.   Theoretical studies and practical work has established that 1% Ni in weld metal is the optimum to get the desired requirements of sour service. Acceptance  of Ni beyond 1% is still debatable and subject to many studies.   Please see the attachments for your reference and information.   Thanks.     Pradip Goswami, P.Eng,IWE Welding & Metallurgical Specialist Ontario, Canada pgoswami@quickclic.net pgoswami@sympatico.ca On Sat, Jul 22, 2017 at 1:34 PM, 'Shashank Vagal' via Materials & Welding < materials-welding@googlegroups.com > wrote: Hello dear, May be you will find it explained more extensive...

Dear Sir,  Good Morning , i Have Agree with your commends , I like to know that when you doing vertical Weld Joint at Dry method , we can able to use same yoke method  if we have any problem , let me know what kind of problem we will face on it  Material : S235J2 (Zinc Coated ) Best Regards Sankar.k Welding Inspector  Enka  On Thursday, November 3, 2011 at 12:42:00 AM UTC+3, hpi001 wrote: You only can use the prod method when putting the electrodes on the weld surface because of the magnetic field lines, in my opinion a Yoke will be the best method. Beside that when you don't have proper contact with the probes there is a risk of arcs which can cause copper penetration in the surface of your material.   Met vriendelijke groeten / Best Regards   Herman Pieper   Pieper Quality Support & Inspection Phone: +31 (0)521 380083 Fax:     +31 (0)84 7539225 Cell:     +31 (0)6 51691215 www.pieper-qsi.nl   Van: material...@ googlegroups.com [mailto: material...@ googlegroups.com ] Namens ...

Hello, What is the difference between 7018 and 7018m?  Also, I see on ebay rods that are 7018m have a designation of level 1 - what is the level 1?
