    I have a differential lock (optioncode 1G80) in my 14 Bolt SF. The problem is that the lock doesn’t activates itself in the correct moment and thus makes an adventurous handling.
    Is the rear axle strongly enough if I welt on the spider gears? I drive 50% on highways.

    Probably a Gov Lok ,which is known to have weird engagement and failures too. The way the gov lok works is kinda screwy from what I've heard which is why they are prone to breaking. But I am not any kind of an expert on this

    It should be plenty strong to weld it. If you have larger than 36's I would be a little cautious but if they are smaller go for it, just make sure you clean it well first and weld it good. Starting fluid works well for the final clean up before welding just let it evaporate completely first. You should also put axle grease on your ring and pinion gears and the center pin so you dont get weld splatter on them.

    Thanks for the responses.
    First I’ll try a welding, because we gets only some 14ff in very bad condition from the US-Army, here in Germany. These have then the wrong ratio and costs much cash (around 1000$).

    I'm no expert on the gov-lock (I've never even been into one) but, I don't think you will be very successful welding it. Normally people weld up open differentials where you have easy access to the spider and drive gears. Gov-lock is a whole different animal. I would do some more checking before starting to weld on the gov-lock.
