Weld calculation
Weld under tension or shear, weld thickness a and weld length l; comparison with the permissible weld stress.
in accordance with DIN EN 1993-1-8 (simplified method, without partial safety factors)Rough estimate without partial safety factors. For the verified report: Hebelwerk.
For a fillet weld, the calculated weld area is a · l. The calculator applies the force to this area and compares the stress with the permissible value. This is sufficient for a quick estimate on brackets, gussets and frame joints; however, for the verification in the report, the forces resulting from movement and the bending around the weld root are required.
What the computer calculates
σ = F / (a · l · n), where n is the number of seams of equal length. The permissible value depends on the material and the type of load and is specified by you.
What he doesn’t realise
Bending moments, combination of normal and shear stresses according to the direction-dependent method, fatigue strength and weld quality.
What Hebelwerk adds to this.
Weld verification on gussets and brackets using forces derived from kinematics, including bending about the weld root. Report with calculation steps, version and release stamp.
