a517 material welding Welding ASTM A514 or A514M-05 steel? - The Fabricator
Making the Choice: Filler Metals. When joining A514 to other low-alloy steels or carbon steels of lower strength, use a filler metal with strength that meets the lower-strength base material's properties. For example, when welding ASTM A36 to A514, use a 70-KSI-tensile-strength electrode to match the lower-strength material.

Strict and usual welding controls as required for Q&T steels would be advisable.Use of SMAW welding electrodes, SFA 5.5,E-100/11018M are normally recommended for these grades. One may use the conventional weld grooves for such steels.
a517 material welding ASTM A517 - SSAB
ASTM A517. The ASTM A517 specification is the Standard Specification for Pressure Vessel Plates, Alloy Steel, High-Strength, Quenched and Tempered material used in the application of fusion welded boilers and pressure vessels. Under this specification, the plate thickness determines the grade selection and the mechanical properties.

ASTM A514 is primarily used as a structural steel and also used for pressure vessels designated as ASTM A517. The Procedure Handbook for Arc Welding groups A514 and A517 under the same category (Category D) and recommends the exact same processes and procedures.

Dec 21, 2006 · Welding A514 and A 572. As long as the filler metal is of equal or greater strength in joining two dissimilar strength materials, E7018 would work. Some Design Engineers prefer to have the weld metal strength match the higher strength base material.You need to be more specific on the Grade of 514. What exactly are the steels you intend to weld and the type of welding? Yes, I have had certain grades of ASTM A 514 welded to itself and to ASTM A 572 with no problems. The welding needs to be performed with caution on certain grades of steel to avoid harming the intended mechanical properties of the steel.The A514 is Grade Q and the A572 is Grade 50. Imagine a cylindrical tank with capped ends - the cylinder is A572 and the caps are A514. Under the tank's intended load, the seam between the two different steels sees about 25,000 psi. The center of the caps can be as high as 50,000 psi. The seam has a full penetration weld.22west; Why are you using such a mismatch in yield/tensile strengths between the vessel (A 572) and heads A 514 Grade Q)? What is the function of the tank? Is it pressure-containing? These materials are not really suitable for pressure-containing applications. ASTM A 514 Grade Q is a high strength, quenched and tempered steel plate that requires extreme caution for welding. This material is sensitive to cracking during post weld heat treatment. If you intend to build a pressure retaining tank, I would use pressure vessel quality steel plate that has improved weldability versus high strength structural steel.It is not a pressure vessel. It is a structural design, I only used a tank analogy to better expain the geometry. The "cap" or the high strength steel plate is stressed in the middle due mechanical loading - not pressure loading. You mentioned A514 cracking sensitivity during post weld heat treatment, is this true for welding that steel in general or only when welded to a dis-similar material (sauch as A572)? I would like to read up a little on this A514 cracking sensitivity can you recommend a book? Thanks for your help.22west; Ok, I thought otherwise when I saw the word tank and high strength steels in your OP. Well, the ASTM A 514 Grade Q steel plate can crack during a post weld heat treatment because this plate contains vanadium, regardless if welded to itself or to another material. Vanadium is added to increase (ambient and elevated temperature) strength and typically renders a steel more susceptible to cracking during post weld heat treatment (PWHT); the term is also called reheat cracking. This is the reason why I raised the red flag cautionary statement. What happens is that during PWHT of the A 514 Grade Q plate to relieve residual stresses and to reduce the hardness of weld and of the base metal heat affected zone from welding, vanadium forms carbides that significantly strengthen the metal grains along the base metal heat affected zone of the weld. Upon exposure to elevated temperature for PWHT, the grain boundaries of the steel are weaker than the grains themselves because of the vanadium carbides, thus promoting cracking along the grain boundaries to relieve the residual stresses, instead of the material absorbing these stresses. If you must use the higher strength A 514 Grade Q steel plate for the end caps, I would qualify a welding procedure using the combination of A 572 and A 514 with PWHT. The selection of PWHT should be 1100 deg F, which is about 50 deg F less than the original fabrication heat treatment (min 1150 deg F) for this material. You need to use low hydrogen weld electrodes and keep the interpass temperature during welding at or below 450 deg F. Your preheat should only be 150 deg F if at or under 1.5” in plate thickness. Over this thickness, I would increase the preheat to 250 deg F. The ASTM A 572 Grade 50 is readily weldable. You filler metal should be E10018-x for this weld procedure qualification.Thanks for the information - you have been very helpful.metengr,you conclude by recommending that the "filler metal should be E10018-x for this weld procedure qualification." But what of the provisions of D1.1 Sec 3.3 for undermatching relationships, which permits use of fller metal for lower strength group? Does this not mean E7015,16 or 18 will be more appropriate per AWS D1.1 table 3.1?henri2; Agreed, that the lower strength filler metal is certainly appropriate. I don't have D1.1 handy. I believe the decision to use the lower strength filler metal is left up to the Design Engineer for the specific application. As long as the filler metal is of equal or greater strength in joining two dissimilar strength materials, E7018 would work. Some Design Engineers prefer to have the weld metal strength match the higher strength base material.The lower strength is recommended because the higher-strength materials are more brittle, and considering that it doesn't do you any good to have your weld higher strength than adjacent material, you are sacrificing ductility for no good reason. Would ASTM A 709 Gr. HPS 70W be suitable for your application? It's supposed to be more weldable than A 514. Hg Eng-Tips policies: FAQ731-376I mean grade HPS 100W. I'm an idiot.
