Has anyone welded a Grin torque arm?

[offGridDownUnder]

The v3 All-Axle torque arm attaches in one orientation only - the splines and screws are not radially symmetric. I have a use case that requires the arm be rotated 90 degrees from it's built position relative to the motor. Justin suggests cutting it and welding it, and mentions it's 6061. But he didn't state the temper.

T6 is expensive to restore. T4 is more practical.

I've asked, but not heard back yet. Does anyone have information about welding a Grin torque arm?

Thanks. If I do hear back from Grin, I'll append the reply.

T6, T4... Doesn't matter. Both will lose temper in the HAZ when welded. If it's a structurally critical area where it's welded, it will bend easy and separate soon after. Post heat Treatment is necessary to restore.
