Still working on that motor stand.......

Question is. What if any problems come about from welding mild steel to 4130? What filler would be best (TIG)?

In the effort to save a couple bucks on the deal, I was thinking about using mild steel to make some sleeves and bungs that I will need from mild steel rather than pop for 4130. There will only be a few so weight will not be an issue and strength isn't nessecarily a factor either, unless the welds on the bungs will be overly prone to failure. The welds on the sleeves will see no stress, but the bungs will be in tension.

Thanks in advance.
