Improper Weld Contour Deﬁnition: When the weld exhibits less than a 135° transition angle at the weld toe. '35" Cause: Poor welding technique Q/ Prevention: Use proper techniques. A weave or whip motion can often eliminate the problem. Repair: The weld face must be feathered into the base plate.

This type of welding defect occurs when there’s a lack of proper fusion between the base metal and the weld metal. It can also appear between adjoining weld beads. This creates a gap in the joint that is not filled with molten metal. Causes:

Remedies: 2020-05-31 · This type of defect occurs only on welding GTAW. Defects occur due to the melting of tungsten into the weld metal. This defect will be known if we use radiography testing, the defect looks like a light area. Causes Tungsten Inclusion : The Tungsten electrode is in contact with the weld pool during the welding process. A welded defect is a flaw that inhibits the usefulness of the steel pipe and there is a wide range of these effects with causes. Testing method for the defects on the steel pipe Normally, there are various testing methods to ensure the appropriate weld standard has been applied to the steel pipe but during fabrication, probably due to some errors, the pipe ends up getting some defects.

In this condition the weld metal rolls and forms an angle less than 90 degrees. Causes of Overlap: 1.

The Weld Crawler is a dedicated scanner for long seam welds that allows simultaneous deployment of PA UT and TOFD techniques, in combination with a powerful and portable data acquisition unit. A two-sided phased array UT examination using standard shear wave probes gives excellent detection capability on planar and surface-breaking flaws.

If the weld length is five feet or less, gauge a minimum of once per weld (3). Black Patch Emulsion carry over, Grease or oil after TM. Ridge build up Improper elongation 5% Baby coil Defect observed, 5T Tension between coiler.

These defects differ from the desired weld bead size, shape, and quality. Welding defects could occur either from the outside or inside the weld metal.

Resistance Spot Welding Defect Troubleshooting Guide The WeldHelp Resistance Welding Troubleshooting Guide is written for operators and engineers to help diagnose and solve common spot welding defects and issues, projection welding and seam welding applications. A widespread welding defect may cause by inappropriate MIG welder wire feed problems that are occurred by worn driver rolls. Key: Clean the driver roll periodically and remove all the dirt from the liner for avoiding this problem.

Although overlap is more of a weld discontinuity, it’s still classified as a defect. Mostly, overlap occurs in butt and fillet welds. When an overlap occurs, it means that the metal is not completely fused. Attached is a crude drawing of the weld joint ( desired on left and cold-roll or overlap on the right ) and two pictures of one section where this defect was found.
