Aluminum spool gun work

[MMW]

Doing 100 pcs. I just do the welding as my customer is the machine shop. Not sure what the end use is but we (the machinist & I) did this job for two years & then lost it due to price. Apparently the end user has bought them from a few different people since then for less money & finally realized cheaper isn't always the best option so now they are back to us because of quality issues.

Aluminum round that has a cavity bored into it with some ports & a slug with fancy machining on the inside that is then pressed in. I just preheat & weld. 3/64" 4043 wire, 27.5 volts, 4.5 wire speed on a 30a spool gun, two passes, wire brushed, done.

The first three or four looked like they'd be fun!

Does that weld get machined off?

[MMW]

No machining per say, just some holes drilled & tapped on the welded surface.

Those look a lot like the base of load cells we use on our scales.

Im really surprised that the machine shop doesn't have a welder.

The machine shop doesn't need a welder because they have me. They don't have a enough welding to justify a welder plus they don't have any space for a welding area.
