Welding visual inspection | PDF

This document provides a handbook for visual inspection of welds. It includes sections on visual inspection responsibilities and techniques, definitions and images of common weld defects such as cracks, underfill, burn

Why do seamless pipes need to be deburred?

Welded steel pipe sometimes has excess metal extruded from the weld. The thickness of the end burrs of cold cut products depends on the gap between the cutting edges. Generally, products are allowed to have a certain

6 FAQs about [Requirements for burrs in energy storage welding]

What causes burrs in welding?

Even during spot and roller seam welding, burrs can form and have a negative effect on dynamic fatigue strength (Ref. 16.2.2.2-2). Unfavorable welding parameters (excessively high welding current) or seams that are too close to the edge of the sheet metal, can cause the melt to escape (Fig. "Welding flaws").

How to minimize burrs after machining?

Burrs can be minimized by selecting proper tool geometry, tool materials, coolant, machining parameters, work piece material, process planning, and tool path design. Although no method can eliminate burr formation, deburring is essential to remove burrs after machining.

Do ERW welded pipes have burrs?

ERW (Electric Resistance Welded) pipes can sometimes have burrs or sharp edges as a result of the welding process. Removing these burrs is essential for safety, aesthetics, and to ensure the pipes meet specific industry standards. ERW welded pipe manufacturers have compiled the 9 most commonly used deburring methods for you: 1. Manual Grinding

What is the first step to minimize burrs?

Selecting proper tool geometry is the first step to minimize burrs. Burrs can be minimised by selecting proper tool geometry, tool materials, coolant, machining parameters, work piece material, process planning and tool path design. As there is no method that can eliminate burr formation, thus deburring is essential to eliminate burrs after machining.

Do process parameters for electromagnetic heating affect Burr morphology?

The correlations between the process parameters for electromagnetic heating and burr morphology are disclosed quantitatively by expounding the extrusion welding process for welded pipes under electromagnetic heating for the purpose of exploring the welding quality characterized by burr morphology under different process parameters.

Why are burrs an issue in machining?

Burrs, undesired and unwanted materials, often come in various shapes and forms depending on the machining process and work piece materials. This burr formation causes reliability problems on the parts and degrades their performance.
