Overview of the Visual Inspection Class

Visual inspection of welds in all steels may begin immediately after the completed welds have cooled to ambient temperature. Acceptance criteria for ASTM A 514, A 517, and A 709 Grade 100 and 100 W steels shall be based on visual inspection performed not less than 48 hours after completion of the weld.

Aws D1.1 Visual Inspection

Visual testing is the most commonly used nondestructive testing method in the industry. Most test methods require that the inspector looks at the surface of the part being inspected which means that visual inspection is the first step for these other test methods. As the name implies, VT involves the visual observation of the surface of a test object to evaluate the presence of surface discontinuities. VT inspections may be by direct viewing, using line-of-sight vision, or enhanced viewing methods. Corrosion, misalignment of parts, physical damage and cracks are just some of the discontinuities that may be detected by visual examinations. Corrosion, misalignment, physical damage, and cracks are just some of the discontinuities that may be identified by visual inspection.

Amazon Lookout for Vision is a machine learning (ML) service that spots defects and anomalies in visual representations using computer vision (CV). With Amazon Lookout for Vision, manufacturing companies can increase quality and reduce operational costs by quickly identifying differences in images of objects at scale. For example, Amazon Lookout for Vision can be used to identify missing components in products, damage to vehicles or structures, irregularities in production lines, miniscule defects in silicon wafers, and other similar problems. Amazon Lookout for Vision uses ML to see and understand images from any camera as a person would, but with an even higher degree of accuracy and at a much larger scale. Amazon Lookout for Vision allows customers to eliminate the need for costly and inconsistent manual inspection, while improving quality control, defect and damage assessment, and compliance. In minutes, you can begin using Amazon Lookout for Vision to automate inspection of images and objects–with no machine learning expertise required.

Benefits

Quickly and easily improve processes

Amazon Lookout for Vision gives you a fast and easy way to implement computer vision-based inspection in industrial processes at scale. You can get started by providing as few as 30 images for the process you want to visually inspect. Amazon Lookout for Vision automatically creates a model and analyzes images from cameras that monitor the live process line to spot any differences compared with the baseline images.

Increase production quality, fast

With Lookout for Vision you can reduce defects in production processes, real-time. It identifies and reports visual anomalies in an easy-to-use dashboard so you can take action quickly to stop more defects from occurring – increasing production quality and reducing costs.

Reduce operational costs

Lookout for Vision reports trends in your visual inspection data, such as identifying processes with the highest defect rate or flagging recent variations in defects. This gives you the ability to determine whether to schedule maintenance on the process line or reroute production to another machine before costly, unplanned downtime occurs.

Low setup costs

Machine vision systems require purpose-built smart cameras that are expensive and slow to install. Using Lookout for Vision you can enable less costly cameras (that you might even already have installed) to become ML-enabled visual inspection cameras, no ML expertise required.

Accurate results in challenging conditions

Machine vision systems usually require highly controlled imaging conditions to deliver accurate results. With Lookout for Vision you can accurately detect defects even when natural lighting variations and other conditions found within industrial environments occur.

Continuously improve accuracy

Quality managers or process engineers can view and verify predicted defects in Lookout for Vision. Once verified, the feedback is used to update the ML model, resulting in higher accuracy and improved performance.

How it works

Step 1: Collect images that show normal and defective products from your production line and load them in to the Amazon Lookout for Vision console.
Step 2: Label images as normal or anomalous and Lookout for Vision will automatically build a model for you in minutes. Tune your model to improve defect detection by adding images to the dataset.
Step 3: Use the Amazon Lookout for Vision dashboard to monitor defects and improve processes.
Step 4: Automate visual inspection processes real-time or in-batch and receive notifications when defects are detected.
Step 5: Make continuous improvements by providing feedback on the identified product defects.

Use cases

Detect part damage

You can detect damage to a product’s surface quality, color, and shape. For example, you can detect dents, scratches, and poorly welded surfaces on an automotive door panel during the fabrication and assembly processes.

Identify missing components

You can identify missing components based on the absence, presence, or placement of objects. For example, you can detect a missing capacitor in a printed circuit board or an omitted label on a battery casing.

Uncover process issues

You can detect defects with repeating patterns, which can indicate underlying process or machine issues. For example, detecting repeated scratches in the same spot on a silicon wafer, which combined with machine sensor data, can be used to identify an underlying process or mechanical issue.

Customers

Dafgards is a household name in Sweden, manufacturing 15 different types of frozen pizzas at over 100 pizzas per minute.

“To uphold our brand and deliver the freshest and tastiest customer experience, we want to ensure that all our pizzas are adequately covered in cheese and with the correct toppings. Early in our production process we installed a machine vision system to detect proper coverage of cheese across a pizza’s surface. While this system served well for our original inspection requirement, the system is unable to detect defects on new product types that include multiple toppings. Amazon Lookout for Vision automates and scales inspection of diverse product types such as a cheese pizza with vegetables using the same machine vision system. We successfully expanded our quality assurance for new product types with minimal impact to operations.”
