Design of Welded Connections

Construction Software

Structural welding belongs to a method by which the sections to be attached are heated and fused, through additional molten metal at the joint.

A comparatively small depth of material should be molten, and after cooling, the structural steel and weld metal will function as one continuous part where they are connected.

The supplementary metal is deposited from a special electrode, that is a component of the electric circuit with the connected part.

This civil engineering tutorial focuses on weld connection design.

For this purpose, solution is given on the following problem :-

Problem: Create the design of a weld connection that is provided to transfer a dead load of 110 kips and live load of 380 kips with the use of two channels section C10 x 30 containing web thickness 0.673 inches along with a guest plate of 2 inches.

The type of electrode should be applied as E70xx and all materials should be A36 steel.

The calculation is done on the basis of the following data :-

D.L = 110 kips
L.L = 380 kips
G.P Thickness = 2 inches
Electrode = E70xx

Two section = C10 x 30
Gross cross section area = Ag = 8.82
Web thickness = 0.673 inches

A36 stands for a common structural steel with least yield strength of 36 Ksi (36000 Psi)(250 MPa).

To know the complete method, go through the following video tutorial.
