Materials & Welding

This specification covers recommended procedures for the tube end welding of tubes ranging from ½ in (15 mm) to 1½ in (40 mm) nominal diameter and from 1.6 mm to 4.1 mm wall thickness to tube plates of 15 mm and over, in ferritic and austenitic materials. it covers materials, design, PQR, strength tests, leak testing, expansion etc. On Sat, Feb 27, 2010 at 1:30 PM, Praphulla < praphulla.dp@gmail.com > wrote: Dear All, Can anyone help me to understand the requirements of EEUMA 143?

Either TIG or MIG would be suitable processes for welding 5-mm thick 5052 plate, but MIG would generally be more productive.  The preferred filler metal or electrode alloy for welding 5052 would be 5356. The low strength of the fillet welds made using LH 409 electrodes is likely due to incomplete fusion to the base metal.  Welding aluminum is more challenging than welding steel and most other metals due to the high thermal conductivity of the base metal.  It is difficult to achieve complete fusion, especially at the start of the weld, using conventional arc welding.  This is an ...

Dear all, Our welding consumables intended for use in duplex stainless steels will normally give a weld metal with FN 35 -50.  The weld metal mechanical properties are strongly dependent on ferrite number. Higher ferrite numbers, > 50, gives higher tensile strength, lower elongation and maybe also lower Charpy values. Welding with too low heat input will give a weld metal with too high FN, resulting in bad mechanical properties. Too high heat input will give too much brittle intermetallic phases. Since the ferrite is transformed into brittle intermetallic phase, the FN measured in the weld will be low.. Measurement of ferrite number in real weldment can be carried out with a precision of +/-10%, according to investigations carried out by IIW. Best regards, Claes Gillenius Development Engineer, MMA.

What grade of duplex it is? and what process you are using? you want general acceptable values or how to control FN in the weld? what is your process fluid? Chemical composition, welding and heat treatment are process parameters that determine the properties. To control all these parameters, some specifications are “over-specified”, which sometimes lead to conflicting requirements. One example is when an over-alloyed filler wire with 9% Ni is required for the longitudinal weld, and nitrogen is added to the gas for pitting resistance, in which case the ferrite content after heat treatment may fall below 30% in the weld. Most specifications allow minimum 30% ferrite in the weld, due to an expected risk for SCC, in spite of that the risk for SCC being negligible in the intended process environment. For duplex steels the ferrite content is largely depending on the chemical composition and the thermal history. For the parent steel it is con...

Dear Rutvik and Pradip, As addition on the remarks of Pradip especially regarding "you may use cast material" the following: Welding procedure qualifications according to ASME section IX are not allowed as base for WPS qualifcation in casting repairs according to ASTM A995. This specification clearly mention under chapter 11 that all procedures and/ or welders need to be qualified according to ASTM A488. This specification is especially for casted materials and requires qualification on casted base materials only so often this is not the case for ASME section IX qualifications. Chemical composition also need to be similar to the material to be weld. If the comapny has no qualification according the ASTM A488 they are not allowed to execute any repair.
