Trust me I had a swingarm that needed welding done to it, and my welder had a hell of a time trying to weld it because it was filled with foam like yours...The foam kept melting and contaminating the welds. Didnt want to penetrate and was just making a mess.
Some swingarms come filled with something similar and others have rubber injected into them...
