  • Guidelines for Witnessing Welding Procedure Qualification ...

    Fillet welded joints are not only the most frequently used weld joints but are also one of the most difficult to weld with any real degree of consistency. Fillet welds require a higher heat input than a butt joint of the same thickness and, with less skilled welders this can lead to lack of penetration and/or fusion defects that cannot be detected by visual examination and other NDT techniques.

  • Welding Procedure Guide - CWB Group

    Type of Weld Butt weld cover butt weld in any type of joint except branch connection Butt welds do not qualify fillet welds or vice versa When a welder is qualified by butt weld test, a supplementary fillet weld test piece can be welded which shall be in a plate thickness of at least 10mm and completed using a single layer in the PB position ...

  • Inspection and Testing for Welding Procedure Qualification

    Each of the WPSAmerica .com prequalified welding procedure specification has practical weld parameters, right shielding gases for spray, short circuit or globular mode of transfers, with helpful notes, technique or code's rules, based on the latest edition of AWS codes. It has been prepared by professionals and code experts in weld industry; it ...

    The fillet weld break test is a mechanical testing process for examining the root penetration in a destructive manner. While the macroetch test provides penetration depth of the specimen in a given area, the fillet weld break test examines the root penetration for the entirety of the specimen. The test includes the potential failure points of ...

  • NDT Procedure for Weld Visual Inspection

    Welds which are made from both sides of a joint and fillet welds are considered as welding “on backing,” in which case the same process and electrode may be used on both sides. Alignment shall be done using external alignment clamps or by tack welding the ends.

    Jan 18, 2021 · Using the thickness of the thinner part joined, T/2 = 12.5mm +1 = 13.5 mm ideal fillet weld size. With Imperial dimensions replace 1 with 1/16", so 1" / 2 = 1/2" + 1/16" = 9/16" ideal fillet weld size. Not perfect in all cases, just a rule of thumb. Ref D1.1 -

    Fillet Weld – A weld of approximately triangular cross section that joins two surfaces approximately at right angles to each other in a lap joint, T-joint, or corner joint.


    Many AWS Codes allow the use of Pre-qualified Welding Procedures. Pre-qualified procedures are written documents that define welding parameters for the welder and are within defined limits set by the referencing Code (e.g., AWS D1.1) Welding procedures that exceed the limits for pre-qualification must be qualified by testing

  • Welding Certification - A Basic Guide from Structural to Pipe ...

    The remaining welded sample is used as the fillet weld break test and is broken against the weld to reveal the internal structure of the weld for inspection. Inspection and Testing for Groove welds (Butt Joints) – This involves visual inspection, followed by two transverse tensile tests, two root bend test and two face bend tests.

  • Welding -

    Jan 30, 2018 · A welding procedure specification (WPS) is a written document providing direction to the welder (or welding operator). It contains all the necessary parameters viz. joints, base metals, filler metals, positions, preheat, PWHT, gas etc. (including ranges, if any) under which the welding process must be performed.

  • Basic (Overlooked) Steps to Develop a Welding Procedure ...

    Welding procedures are usually divided into two categories, the Procedure Qualification Record (PQR) and the Welding Procedure Specification (WPS). Procedure Qualification Records are the documented values used during the actual welding test and all the inspection and test results obtained from the actual test samples.

  • When to use full strength steel in fillet welds?

    root opening during root pass welding. Fillet weld sizes, as shown on the Welding Procedure Specification shall be used unless otherwise detailed on the engineering drawing. Fillet welds shall be made so that they penetrate fully into the root.
