May 05,2016 open top tanks Maximum Thickness of Reinforcement on Welds for Radiography Examined Joints#0183;After welding,welded joints were examined visually and photographed.Visually accepted joints were inspected with X-ray radiography.Specimens for macro- and microstructural investigations were prepared by cutting across the weld seam,polished and etched with a solution of 90% ethanol + 10% nitric acid and 97% ethanol + 3% nitric acid Reinforcing Pad - an overview ScienceDirect TopicsA.Keith Escoe,in Pressure Vessel and Stacks Field Repair Manual,2008.Lifting lugs are connected to the shell with fillet welds.If lifting lugs are welded to a reinforcing pad,and the pad is connected to the shell with fillet welds,then the capacity of the lifting lugs is a function of the strength of the pad fillet welds,as well as the fillet welds attaching the lug to the pad.Radiographic Testing ProcedureSee T-283.2.shall be as specified in Table T-276.A thinner or thicker hole-type IQI may be substituted for any section thickness (a) Welds With Reinforcements.The thickness on which the IQI is based is the nominal single-wall thickness plus the estimated weld reinforcement not to exceed the maximum permitted by the referencing Code Section.

Radiograph Interpretation - Welds

Inadequate weld reinforcement is an area of a weld where the thickness of weld metal deposited is less than the thickness of the base material.It is very easy to determine by radiograph if the weld has inadequate reinforcement,because the image density in the area of suspected inadequacy will be higher (darker) than the image density of the Pipe Welding - How to Pass a SMAW 6G Pipe Welding Pipe welding and everything you need to know how to stick weld pipe to pass a 6G (open root) pipe welding certification.Covering bevel set-up,tack welding,E6010 open root,E7018 hot pass and cap.With detailed accurate information and pictures of the electrode angles,machine set-up,pipe welding techniques,and the entire welding certification from start to finish!Non Destructive Testing - Hydrostatic testing of pressure Hot work includes everything related to welding or the post weld heat treatment (PWHT).All radiographic and ultrasonic inspections should be carried out before the pressure test is started.Conducting 100% radiography of all the weld joints assure that your weld joints are defect free but can never provide you with the assurance of mechanical

Fillet Welded Joints - A Review of the Practicalities - TWI

Fillet welded joints such as 'T',lap and corner joints are the most common connection in welded fabrication.In total they probably account for around 80% of all joints made by arc welding..It is likely that a high percentage of other joining techniques also use some form of a fillet welded joint including non-fusion processes such as brazing,braze welding and soldering.Castings Viewing RadiographsBasic radiography 12-dense metal welds - ScienceDirectDec 01,1970 open top tanks Maximum Thickness of Reinforcement on Welds for Radiography Examined Joints#0183;(BS 2600 allows an increase of up to 10o in the weld throat thickness.ASME Section VHI allows a weld reinforcement of up to 1/sin (3mm).) Some welds are suitable for radiography without dressing because they do not show a marked ripple nor heavy spatter losses.Branch Connection - an overview ScienceDirect TopicsJul 02,2010 open top tanks Maximum Thickness of Reinforcement on Welds for Radiography Examined Joints#0183;Fillet welds on both sides or a full penetration T-butt joint will permit substantially increased loads before failure occurs (Fig.5.15).Dynamic performance of T-joints is not good the change in section from the horizontal to vertical member gives rise to high stresses at the weld toes,drastically shortening the fatigue life.
