      Jul 01, 2017 · Weld defects, causes, and remedies 1. Weld Defects, Causes, and Remedies 2. Objective:At the end of the lesson, you are expected to; Identify the different weld defects its causes and remedies. 3. A weld should have a good appearance. However, a defective weld is one that will be strong enough to do the job and may fail after it is put into used. Welding Defects Causes and Remedies Welding Cause:Micro stresses from weld metal shrinkage pulling apart weld metal as it cools from liquid to solid temp. Prevention:Preheat or use a low tensile filler material. Cold Crack Definition:A crack that occurs after the metal has completely solidified Cause:Shrinkage, Highly restrained welds. Welding Defects Types, Causes & RemediesDec 07, 2020 · Welding Defects Types, Causes & Remedies Welding defects are simply defects or unacceptable imperfections in the welding process. This article holds the elaborative analysis of different welding defects, its various types, and the subsequent causes and remedies.

        • Crater. The crater is a kind of crack which occurs when the welding arc is broken and molten metal Undercut. The undercut is a kind of groove formation around the weld reducing the cross-sectional Spatter. Spatter, as the name suggests is a small particle from the weld that gets deposited on the Distortion. Distortion is a result of molten metal shrinkage at the side of the weld joint. Its not Hot Tearing. Hot tearing is similar to cracks but occurs at the edge of weld joints. It occurs due to Surface Cracks. Surface cracks are different from another internal weld crack in the sense that 9 Different Types of Welding Defects [Causes, Remedies] PDFApr 12, 2021 · Causes of Weld Crack:Remedies of Weld Crack:Using hydrogen while welding ferrous metals.

                  • Porosity:It is common type. In this defect, air bubbles or gases are present in the weld zone. The Spatter:Metal drop expelled from the weld that stick to surrounding surface is known as spatter. Slag inclusions:Slag inclusions are compound such as oxides, fluxes and electrode contains Incomplete fusion:In this types of welding defect gap is not totally filled by molten metal. It is due to Incomplete Penetration:It is occurs when the depth of the welded joint is insufficient.Under cutting:This defect occurs when base of metal melts away from the weld zone and the Under filling:Under filling occurs when the joint is not filled with the proper amount of molten metal.Inclusion:It is a defect in which several passes are made along a V-joint when joining thick plate Lamellar tears:This is mainly a problem with low quality steel. It occurs I plate that has a low Cracks:Cracks may occur in various location and direction in the weld area.
