A source of gamma radiation is placed on one side of the weld, and a photographic film is placed on the other. Bubbles and weak points will appear on the film.

A weld log is a Quality Managment tool that acts as a database used to keep an ongoing record of welds made during construction fabrication type projects. The Weld log is used to record Important information recorded as "weld number" Welders Stencils", "Weld Procedure", "Weld Type" Material Type" "Project#" and any other important information to ensure the traceability and Quality Assurance of each welded junction during fabrication or repair activities. The best example can be found here: http://sites.google.com/site/masterweldtracker/
You do not have to check a gear backlash. All you need is a dial indicator to plug in and i will check for you.
There are several types of welds, including butt welds, where two pieces are joined end-to-end; lap welds, where one piece overlaps the other; corner welds, used to join two pieces at a right angle; and T-welds, which connect two pieces at a T-shape. Other types include edge welds and plug welds. Each type serves specific applications based on the joint configuration and structural requirements.
I have been stuck on this question 'what radiation should be used to check the thickness of foil?' and recently I have found out that it is 'Gamma' radiation as it can penetrate through a variety of strong surfaces.

Short welds made to hold a joint in proper alignment are called "tack welds." These temporary welds provide stability during the assembly process, ensuring that parts remain positioned correctly before the final welds are applied. Tack welds are typically small and used primarily to secure components in place for further welding operations.
Glue, metal bolts and welds.
The plural of 'weld' is 'welds', as in "He made several welds to the car frame."
Gamma radiation from cobalt-60 and cesium-137 is commonly used in medical applications, particularly in cancer treatment through radiotherapy, where it helps to target and destroy malignant cells. Additionally, these isotopes are utilized in industrial applications, such as sterilizing medical equipment and food, as well as in radiographic testing to inspect materials and welds for integrity. Their ability to penetrate materials makes them valuable for these purposes.

Welded joints can be categorized into two main types: fillet welds and butt welds. Fillet welds are used to join two pieces of metal at a right angle, characterized by a triangular cross-section, providing strength and versatility for corner and edge joints. Butt welds, on the other hand, involve joining two pieces end-to-end, resulting in a smooth surface without protrusions, and are often used for structural applications. Key features of these joints include weld size, penetration depth, and the weld profile, which are critical for ensuring strength and integrity in the finished assembly.
