: The standard does not apply to non-load-bearing (tack) joints, which are instead covered by EN ISO 17660-2 , nor does it cover factory-produced welding fabrics using multiple spot-welding machines.
; for fatigue-loaded structures, designers must account for significant reductions in fatigue strength depending on the joint type. ISO - International Organization for Standardization en iso 176601 pdf
: It provides detailed guidance for four main joint configurations to ensure full load-bearing capacity: Butt joints : Welded via arc, flash, or friction processes. Lap joints : Typically using single-sided intermittent fillet welds. Strap joints : The standard does not apply to non-load-bearing
