Default Rotary Mower

Put new skis on this rotary mower, the man wants hard plates welded on the bottoms so they can be changed when the time comes, he doesn't want bolts. I have tri braze strips being cut and to attach them I was thinking of burning holes in the skis and plug welding from the top instead of stitching along the sides. What do we think of that? I think they would be easier to remove with the plugs by cutting on each side of the plug from the bottom.

I think your idea should work fine. As long as you have good access to the plugs it should be relatively easy to just burn them out when the time comes...

Could use flat head plow bolts so you have a smooth ski.

That sounds like an excuse just to have someone else fix it when it's it wore off. Bolts would be too easy to have to send out for repairs.

The man stopped by this morning and said that when they ware off I will get it back for replacement. This is for a city works department so maybe I am cheaper.

I have a fair amount of experience with Tri Braze. What I can tell you is that even with their special wire and plenty of amps you do not get great penetration. I'll see if I can find the etch I did.

I would not recommend plug welds in this situation, rather fillets you can get to when it needs replacing.

Don't get me wrong, it's good material - hard as woodpecker lips (actually it's the same hardness as ar400) the key advantage to this material is that where ar has hard faces, Tri braze is through hard.

Seeing how the material is hard, the weld might want to crack at the edges.
In these places I like plug welds, no edges to crack.
