To avoid defects like undercut and burn through in welding, it's essential to control heat input by adjusting parameters such as voltage, amperage, and travel speed appropriately for the material being welded. Maintaining a proper welding technique, including consistent arc length and travel angle, helps ensure uniform heat distribution. Additionally, using appropriate filler materials and preheating the workpieces can further minimize the risk of these defects. Regular inspection and practice also contribute to improved welding quality and defect prevention.

How do you prevent the occurrence of slag inclusion and undercut?
The following techniques can be used to prevent slag inclusions: Use welding techniques to produce smooth weld beads and adequate inter-run fusion to avoid forming pockets to trap the slag. Use the correct current and travel speed to avoid undercutting the sidewall which will make the slag difficult to remove.
How will you avoid occurrence of porosity or slag on weld?
To avoid porosity or slag in welds, it's essential to ensure proper cleaning of the base materials by removing contaminants like oil, grease, and rust before welding. Additionally, maintaining the correct welding parameters, such as voltage, travel speed, and heat input, helps achieve a stable arc and minimizes defects. Using high-quality filler materials and ensuring proper shielding gas coverage can further reduce the risk of porosity. Finally, welding in suitable positions and conditions, such as avoiding drafts and excessive humidity, will also contribute to a cleaner weld.
How do you do zinc welding?
Zinc welding is typically done using gas metal arc welding (GMAW) or flux-cored arc welding (FCAW) processes. It's important to use proper ventilation and personal protective equipment when welding zinc to avoid exposure to harmful fumes. Additionally, cleaning the zinc surface before welding and selecting the appropriate filler material are essential for achieving a strong weld.
How do you avoid slag inclusion?
To avoid slag inclusion in welding, make sure to properly clean the joint and remove any contaminants like rust, oil, or paint. Use the correct welding technique and parameters to ensure good fusion between the base metals. Additionally, selecting the appropriate welding consumables and maintaining a consistent travel speed can help prevent slag inclusion.
How to avoid surface concavity in autogeneous welding?
Do you mean your beads are concave and you would like them convex in appearance while autogenous welding is being done? Without knowing what metal you are welding or seeing the technique used I can only offer generalizations. It could be a lack of sufficient sulfur or improper travel speed. Without more info I'm only guessing.Which isn't good when it comes to welding.
