Even though gas metal arc welding (GMAW) is generally considered to be a slagfree process, silicon islands present on the weld surface after welding are a normal (and largely unavoidable) byproduct of both solid and metalcored wires. Unfortunately, they can be troublesome when it comes to postweld cleanup. These islands are often small and hard to see, which can make it difficult to remove ...
