Run a gloved hand over the distressed areas looking for places where it catches to identify protrusions. Some protrusions, such as weld spatter, can be abrasive blasted. Others will require grinding. Welding Defect. Welding defects can be defined as weld surface irregularities, discontinuities, imperfections, or inconsistencies that occur in welded parts. From: Comprehensive Materials Processing, 2014. Related terms: Residual Stress; Friction Stir Welding; Laser Beam Welding; Weld Metal; Spot Welding; Inert Gases; Intermetallics; Magnesium Bluewrist 3D weld inspection solution can help you achieve 100% inline inspection of all critical weld features to prevent downstream defects.

Over roll weld defect

7.11.2 Weld repairs of wheel skids Any thermal cracks over 30 mm and up to 40 mm long in the zone shown in 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. Either the weld puddle is too large (travel speed too slow) and/or the weld metal has been permitted to roll in front of the arc.

The poor overlap does not allow the slag from the previous weld to melt out and rise to the top of the new weld bead. It can also occur if the previous weld left an undercut or an uneven surface profile. The standard form may say to weld overhead, uphill, or downhill, but it doesn't tell exactly what the welder should do to accomplish the weld at hand.

Juga disebut sebagai over-roll. Penyebab Coatings shrink as they cure, resulting in low film thickness over sharp edges and welds, which is a classic cause of coatings failure..

By using large electrodes this defect may occur. 3. High welding current. Remedies for Overlap: 1. Using a proper technique for welding.

In this welding defect, the deposited metal being hot starts developing crack from the nearby edge so that after it has been solidified the crack increase. The hot tear is also known as solidification cracking , due to tearing of the grain boundaries of weld metal before complete solidification has taken place and metal is still in the plastic state.

Slitter rings: Concentric ring patterns on the edges of the roll give the roll edge the appearance of a target. This defect is very common on winders with mandrel-mounted bottom knives after the mandrel has been reground one or more times. Remedies: Periodic pits or convex hulls appear on the surface, and severe roll marks cause the strip to pass through. 1The strip weld is too high or the cleaning is uneven, causing the sticking roller when rolling; 2The hard metal (bead, metal scrap, etc.) or dirt is stuck on the roller.

The cold lap weld defect has been classified into three types namely spatter, overlap and 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. Piping,Welding,Non Destructive Examination-NDTCommon Piping Angles and their Solutions,Known and Unknown Angles and Angle Chart,Solving Rolling Offsets,miter This page describes welding defects that impair welding quality such as pits, undercut, overlap, insufficient reinforcement, bead cracking, arc strike, bead meandering, bent bead and remaining groove.

Rolls High Speed - Buy Tank Turning Roll,Fit Up Automatic Tank Turning Rolls,Welding Turning . Over-roll on a butt weld Mechanical Damage Mechanical damage is an indentation in the surface of the parent metal or weld caused by damage during preparation, welding, dressing or handling. The weld defect is removed by grinding and subsequent rewelding. Aft of the tensioner, the pipe undergoing excavation is highly loaded by bending and tension. The local stresses at the weld repair are intensified during the weld excavation process. Defects in the girth weld are located and measured by radiography or ultrasound. Inability during the welding process to elevate the base metal or previously deposited weld metal to its melting temperature.
