Welding Slag Inclusions: How to Prevent and Remove Them

WebWelding is a way of heating pieces of metal using electricity or a flame so that they melt and stick together. There are many kinds of welding, including arc welding, resistance welding, and gas welding. The most common type is arc welding. Anyone who is near arc welding needs to wear a special helmet or goggles because the arc is so bright. WebElectro-Slag Welding (ESW) Electro-slag welding is another automated welding process that looks a lot like submerged arc welding. It’s used to perform a symmetric, gap-filling weld, in a single pass. The setup is a bit complicated, and so is the principle it works on.
