What is Bridge Cam gauge?
The Bridge Cam Gauge, commonly known as the Cambridge gauge, is an accurate, sturdy gauge for both shop and field applications. It can measure fillet weld leg length and throat thickness, height of weld reinforcement, depth of undercut, misalignment and the angle of preparation.
What are gauges in welding?
Welding gauges are inspection gauges used for checking alignment, checking dimensions before welding, verifying weld dimensions, and checking porosity of welds.
What is a taper gauge?
Taper gages are precision ground to a specific thickness which corresponds to a graduation on the side of the tool. Often used in slots and dimensioning recesses of parts.
How are welds measured?
Fillet weld sizes are measured by the length of the legs of the largest right triangle that may be inscribed within the fillet weld cross section. Fillet weld sizes determine theoretical throat.
What is a snap gauge used for?
Snap gages are among the oldest and simplest measuring instruments. They are used to measure the outside diameter of round parts such as shafts and the thickness of many other components. The first type snap gages were fixed limit gages which only confirmed the part being measured was within its size limits.
What is the proper measurement of root gap?
Generally as per standard the root gap is 3-4 mm max to have full penetration at joint.
What is maximum root gap in welding?
The maximum root opening is approximately 1/8-in. because of the difficulty of refusing the welding flux at the base of the first pass weld. If the root gap is maintained constant for the entire length of the seam, plate up to 3/4-in.
What are the three general types of snap gauges?
Types of Snap Gauging:
- (1) Fixed limit Snap Gauges – Fixed limit snap gauges are designed to assess dimensional tolerance for a single value of the dimensional parameter.
- (2) Adjustable limit Snap Gauges-
- (3) Combined limit Snap Gauges –
- (4) Double-ended Snap Gauges-
- (5) Dial Snap Gauges-
- (6) Thread Snap Gauges-
What is the maximum root opening?
The maximum permissible root opening is 1/32-in. unless the joint is backed sufficiently to prevent the welding composition from flowing through the root opening. With such support greater root openings can be used.
What is the ideal root gap in welding?
Root gap should not exceed 1/16-in. Fusible metallic backing is also used with this preparation with a root gap of at least 1/8-in. The single-Vee groove butt joint with root face and without external backing is also used for two pass welds where plate thickness exceeds 5/8-in.
What is a bridge Cam gauge?
The Bridge cam gauge is an exclusive and multipurpose welding gauge used especially on welded surface and joints. It is a very handy visual inspection tool for welding inspectors.
What is MG8 cam type welding gauge?
MG-8 cam type welding gauge (inch/mm). This stainless steel welding gauge is to measure angle of preparation, depth of pitting, fillet weld length, excess weld metal (capping size), depth of undercut, misalignment (high-low). Measurements are possible in either inches or millimeters.
How is a weld gauge measured?
The gauge has a rotating dial and a sliding pointer to measure weld features. The measurement is displayed in inches and millimeter up to 2” or 60mm.
What do you like most about Gale gauges?
I own many G.A.L. gauges, and this works just as well at a fraction of the price. The compact size is great for carrying every day. The markings are durable. The calibration is spot on. I have not had a problem with any screws losing their ability to tighten, but even if they did, you can buy 5 of these for the price of the G.A.L. branded version.
