Welding Defects, Fixes and Troubleshooting Chart
This summary highlights the main points included in the complete guide.
For the full version with detailed instructions, download the guide.
This downloadable guide provides a complete overview of the most common welding defects and how to identify them across MIG, TIG, stick, and flux-core welding. It explains the causes of issues such as porosity, cracking, undercut, lack of fusion, spatter, distortion, incomplete penetration, and burn-through. The guide also outlines how base metal preparation, machine settings, gas flow, and technique all contribute to weld quality and potential defects.
You will learn how to recognize weld defects visually and through arc behavior, as well as how adjustments to voltage, amperage, wire feed speed, travel speed, and torch angle can correct most problems. The guide also explains how improper polarity, contamination, joint fit-up, and poor shielding gas coverage create inconsistencies in weld appearance and strength.
The guide also covers defect-specific troubleshooting steps such as increasing heat for fusion problems, reducing wire speed for excessive spatter, adjusting travel speed for burn-through, improving cleaning procedures for porosity, and modifying torch angles for undercut or poor bead shape. It provides clear explanations to help welders diagnose the root cause rather than just the symptoms.
Additionally, it provides a detailed troubleshooting chart that lists each defect alongside its causes, visual indicators, and recommended fixes. The chart spans multiple welding processes and offers practical correction methods so welders can quickly solve problems and improve weld consistency.
This overview helps welders understand how to identify, troubleshoot, and correct common welding defects before reviewing the complete downloadable guide.
