What is more critical in structures where fatigue is the dominant design criteria?

What is required when gaging the smallest portion of the weld?

What is the minimum weld length if the welding symbol does not specify a weld length?

What shall finished component dimensions comply with?

What shall weld profiles meet as specified herein?

What is likely accompanied by increased convexity in fillet weld evaluation?

Convex Fillet Weld Evaluation

A good convex fillet weld is identified by its uniformity, adequate fusion, and absence of defects.
Tolerance for measuring up to 10% of the weld length allows for minor variations in the net weld size without compromising structural integrity.

Concave Fillet Weld Characteristics

The maximum size of the inscribed triangle in a concave fillet weld is limited by the curvature of the weld throat.
Weld size in concave fillet welds is determined by measurement at the throat, relying on the weld profile and geometry.

Gaging and Measurement for Concave Welds

The gage for concave welds ensures proper throat depth and leg length, essential for weld performance and strength.
If the gage's extension touches the weld before both sides contact the base metal, it indicates potential issues with the weld integrity and proper alignment.

Design Considerations in Weld Applications

Fatigue resistance is critical in structural designs where fatigue is the dominant design criterion; weld quality directly affects performance under cyclic loading.
When gaging the smallest portion of the weld, precise measurements are required to ensure compliance with engineering specifications.

Weld Length and Specifications

If a welding symbol does not specify a weld length, the minimum length requirement is determined by applicable standards or project specifications.
Finished component dimensions must comply with the tolerances defined in the relevant engineering standards and codes.
Weld profiles must meet the specified criteria to ensure adequate strength, performance, and aesthetic finish.

Convexity and Evaluation

Increased convexity in fillet welds is often accompanied by challenges such as potential stress concentration and decreased fatigue life.
