Hi

API 1104 covers welding procedures qualifications as below,

Case

1.    Clause 5 Welds Containing Filler-metal Additives

2.    Clause 12 Mechanized Welding with Filler Metal Additions

3.    Clause 13 Automatic Welding Without Filler metal Additions

 

 

Diameter range is not essential for case 1 WPS/PQR, i.e. 5.3.2.3 however “the ranges of outside diameters and wall thicknesses over which the procedure is applicable shall be identified”.

 

Means unlike ASME sec 9, WPS/PQR format, additionally you may need to specify the restriction on outside diameter and thickness in order to facilitate to have control on welders use in production welding ( based on clause 6.2.2 d )

Diameter range for case 2 & 3 WPS/PQR is essential variable, refer respective clauses - 12.5.2.5 & 13.5.2

 

 

Also refer API 1104 interpretation ( specifically Page 82 /94 ) attached herewith for more details. There are many questions based on this topic only.

Sir

I need to under stand the meaning of this line , and which code I should refer for Compressor received welding.

Longitudinal seam in adjacent sections shall not be in same line.

[nandakumar pandit]

This means if your shell is in sections, then the longitudinal weldings in all the sections should not be in the same line.

Regards

N. S. Pandit

You might picture in your mind how 'bricks' are laid out or 'concrete blocks'. The Horizontal seams are continuous, however; the 'verticals' are 'offset'. This

is done to prevent a 'crack' starting in one vertical joint from propagating into the next vertical joint. If all the verticals were in one continuous joint, the crack

could propagate from the 1st, into the 2nd, into the 3rd. etc. I hope this helps.

Dear Mr. Rajeev,

If your query is related to Pressure vessel then refer UW-9 (d) of ASME VIII DIV 1, which states that..

 "Except when the longitudinal joints are radiographed 4 in. (100 mm) each side of each circumferential welded intersection, vessels made up of two or more
courses shall have the centers of the welded longitudinal joints of adjacent courses staggered or separated by a distance of at least five times the thickness of the thicker plate.

One advice: Please put a proper subject to your email if you want to get it noticed by a large number of group members.

Special thanks to Mr. Vijay Konathala for sharing the thumb rules of different codes / standards for quick reference.

Hi, 

Did you noticed when constructing building the mason not keeping the brick one over another in same position. The first brick will start from corner, the second line will start by keeping the edge of brick at center of bottom one overlapping. No buildings bricks will be exactly one over another. Use this logic, to make sure the strength of the building. 

Similar way the longitudinal seam of one shell shall not be in same line as it weakens the joint. 

[George Dilintas]

Welds shall not form a cross. There is a rule for staggering, 4 times the thickness of I am not wrong

[Vinay Thattey]

Dear Rajeev ;

You need to have circumferential welds to join two shell parts . A shell is rolled from a plate with seam welds . 

[Kannayeram Gnanapandithan]

Shell course Lseam shall not be in line, it shall be stagged like a T joint
