Welding to Vertical Columns
Welding to Vertical Columns
(OP)
What is allowable to field weld to the I-beam When welding mechanical strut supports to a vertical structure, specifically welding to a 20" Ibeam on the outside of the flange. The structure is a T structure with a single line of columns supporting a roof only. 20' tall 18 foot wide with single row of 20" Ibeam columns





RE: Welding to Vertical Columns
Over welding across an existing flange can cause collapse if that flange is under stress and is critical to the stability of the structure.
A strut welded onto a column - and then loaded - may cause additional moment in the column that could exceed the capacity of that column.
