Both Allowable Stress Design (ASD) and Load and Resistance Factor Design (LRFD) are available in the Weld Capacity Calculator. The ASD method considers the maximum allowable stress for a welded joint based on joint type and base materials, stresses are then checked to ensure they do not exceed the allowable values. In comparison, the LRFD method does not set a fixed allowable stress value but instead involves calculating a welded joint based on factors like the weld strength, material properties, and loading.

Generally welding length is calculated by measuring the linear distance along the joint between the two members that need to be welded. Other factors also need to be considered such as the thickness and type materials being joined.

The SkyCiv Weld Capacity Calculator is useful to determine what the maximum load a joint between two members can safely be expected to stand before failing. Checking weld capacity is a key part of the engineering process to ensure that connections are structurally sound and meet design standard requirements.

The SkyCiv Blodgett Weld Capacity Calculator is useful in a range of structural engineering projects that may include building construction, bridge construction and many other infrastructure projects. Welding also has applications in automotive, aerospace, marine (shipbuilding), railway, offshore and mining engineering. Often due to the nature and safety requirements these industries have particular welding regulations that need to be followed.

A weld treated as a line pattern in a method to graphically represent weeds on engineering drawings. The above weld capacity calculator has twenty-one weld patterns available based on the Blodgett Weld Type outlined in the book Design of Welded Structures. These weld patterns represent a variety of different cross section types that are commonly found in structural members.

There are multiple types of welding joints available that are used in structural engineering. Some common types of joints include Butt Joints, T-Joints, Lap Joints, Corner Joints, Edge Joints, Groove Joints, Plug Welds, Filleted Joints, Spot Weld and Seam Welds.

Blodgett Welding is based on Omer W. Blodgett book Design of Welded Structures.

The SkyCiv Weld Capacity Calculator takes properties include the ultimate strength of the weld, the weld size and the depth of the weld.

The weld capacity calculator returns a weld capacity result as well as a utilization ratio for the welded connection. In addition to this the following results are also provided:

• Preferred Weld Size
• Member Weld Capacity
• Fillet Weld Capacity
• Maximum Effective Weld Size
• Maximum Force per Unit Weld

The SkyCiv Weld Capacity Calculator requires the applied force along the x, y and z directions as well as the moment about the x and z axis.

Currently only the imperial unit system is available.
