Grain structure of a butt weld
WebFor butt welds, depending upon various factors, there is typically a gap of about 2 to 3mm (1/8”) between the workpieces, which is called a root gap. The gap is to ensure that the filler metal fully penetrates the joint. If the gap is too small or too large, it will produce weld defects. Advantages Butt welds provide several advantages, including:
