I have used similar method sometimes when i need to tack weld to large gaps. But i have removed the covering from the other rod, and feed some extra material from it to the weld with my other hand. Works specially vertical positions. Quality of that kind of weld ain't good, so those tacks needs to be removed during welding.
Method you used has couple issues that needs to be notified.
If you weld too thick weld to the groove with one run, it can easily crack.
Slack can easily get under the weld.
Weld is too hot, it makes under cuts to the sides, it may harden...
Welding is one of those things, where you can't use shortcuts.
If you want good quality. Sorry.
Hello Tuomas,
Thank you very much for your recommendations and why sharing your experience, in the description of the video I commented how you came to do it, it was a coincidence, but I think it could be useful in some occasions.
What you tell me is very similar to welding, but with MMA, again thanks, I will put it into practice.
regards
I have to admit, that i have seen professional welders using that method you did. When making large plug welds. Result looks good, so it works in that way.
We have ultrasonic inspections at work, 20% from every welds are randomly selected for inspection. So, i have used to be little too strict with weldings.
Errors are very annoying to fix, when welds are 2" thick.![]()
Very interesting the subject of inspections, the truth is that yes ... imagine that a weld where it has a difficult access to the radial is that it has internal fracture ... well, it took a little while to weld 4 minutes but eliminate that welding and reacerla maybe 4 hours later.
A greeting mate!
Tuomas I agree completely this process would never be acceptable for any structural weld. Trey getting away with that while a QAQC is standing behind you making thermal and visual inspections on every rod burned while welding horizontally on a 56" OD nuclear reactor support leg where the first 100 passes only fill 10% of the grove.
However I have many times used 3 or 4 3/16" Stoody31 hard face rods in this manor for welding up large pad welds on mining buckets and cutting edges. When you start laying down a 1/4 to 1/2" thick 6" wide pad weld that may be 10 feet long you quickly try any trick that you can and if you have a machine capable of burning that much filler at a time you take full advantage of it
Never try to tell me it can't be done
When I have to paint I use KBS products
