Heat treatment issues
Thread Content
I would like to ask everyone: Since tower equipment requires overall heat treatment, does the skirt also need to be treated together?
The fillet welds that join the skirt to the main body require heat treatment
Overall heat treatment is not necessarily required; however, the fillet welds that connect the barrel of the body to the skirt need to be heat-treated. Leave a 500-millimeter length for this connected section, and it’s completely fine to weld the remaining parts after the heat treatment is completed.
The fillet welds that connect the cylinder of the body to the skirt base require heat treatment; generally, one section of the cylinder belonging to the body together with the skirt base is heat-treated, and then the lower part of the skirt base is welded on
I agree with the view from the 4th floor. Sometimes the skirt of tower-type equipment is too high; it’s not necessary to treat the entire area. It’s sufficient to leave a gap of 400–500 mm between the skirt and the cylinder of the lower end cap, treat that area, and then weld a single circumferential seam at the bottom!
