The Art of Working with Aluminum
Friday, December 15, 2017
Sometimes a spun part is just that - a spun piece of metal. After laser cutting the blank, the material is formed, machined to size, washed and shipped. Other times, however, customers request assemblies. In these cases rolled and spun parts are often being welded together. For these items we rely on our expert team of welders.
E.H. Schwab is fully equipped to weld a variety of ferrous and non-ferrous alloys. This week we'll feature some of the typical aluminum welding projects that move through the shop on a regular basis.
The pictures below show aluminum cylinders which are laser cut, CNC roll-formed and seam welded on one of our two programmable Jetline automatic seam welders.

And, when the assembly requires multiple spun parts, our welders first match them for fit and then prep for cleanliness before welding them by hand. A well prepared surface ensures a clean weld with no open pores. This is particularly critical when the weld will be ground off during finishing.

As shown above, the final product appears seamless and is as strong as if it were formed in one piece.
Tune in next week for special holiday wish from all of us at E.H. Schwab!
