Common Causes of Weld Porosity and How to Fix Them
Показать описание
Have you ever experienced porosity in your welds? Peter Torres from BS Industries provides some common causes of porosity and how to fix them.
Porosity stems from inside of the weld, where there should be no voids — causing holes to appear in the weld. Common causes of porosity include low gas flow, a hole in the gas line, spatter in the MIG gun plugging the gas diffuser, rusty/contaminated weld wire and oils/contamination on the base metal. Torres provides an example of weld porosity due to low gas flow. By adjusting the flow to manufacturer specs, located on the front of his Millermatic® 252 MIG welder, he is able to fix the issue.
