By very popular request, we created a video dedicated to bridging gaps on thin aluminum based on the episode all about filling gaps on thin metal (steel). While this gap may be a bit extreme as shown, the techniques demonstrated to control it still hold true.
Special thanks to Blue Demon Welding for sending out a ton of filler rod used in this episode. Check out the link below to pick up some cool Blue Demon products we regularly use!

As a sheet metal worker I've come across this situation countless times. Love your instructions and disgust! The reality of working in a ceiling with 12" of space to crawl through to get to the weld area... you are a breathe of real world application. Thks

i was glad to see you mention that what's important is matching YOUR SPEED to your settings on the machine. either hot & fast or cold & slow. most ppl say there's only one setting & one speed that works, which isn't true. it's all relative to how fast or slow YOU are moving. good stuff! that thing would probably buff out if you got it low enough!

You made all the sense in the world about amps and how they effect pedal, so setting the machine to 20 amps you have full pedal to adjust from 0-20..... cranked to 200, your going to have to have a smart steady foot to maintain say 13 amps....Awesome video man!!!

I recently had a repair of a driveline for my cousin and interestingly enough, the tube pretty close to what you were showing. I struggled a lot getting it fixed for him but would have benefited a lot had I seen this prior to the work. Thanks for sharing.

I know this channel is more of a auto fab channel, but this is pertinent to a lot of metal fab shop and manufacturing applications. I’ve received aluminum parts with 3/16”-1/4” gaps because the press machine was goofy, or the laser cutter fucked up. You just have to know how to do these gaps. Great content as always.

When i was a high pressure gas pipeline welder, their were many time you could not get the ideal spacing for a full pen weld on fix tie in welds.. I have dealt with extreme HI Low and wide gaps. All the welds had to meet API 1104 or ASME Pressure Vessel codes. All where subject to ex-ray evaluation. The bridge technique you used iI employed several times although the gap was not the extreme you used. I also had to use this on hot tie-ins were the natural gas was set on fire in the welding gap and then it was welded shut. I used this technique with SAMW, GMAW and FLux Core arc welding. This technique was used in horizontal and vertical.

Good info. I learned in my early years while stick welding that there are times for the extremes, but I also learned that there are lots of places between the extremes that one can be to get the weld right. God knows that even today I am impatient and put down some fugly welds... but they hold (I am not going to compromise on that aspect). If I may be honest I think that MIG welding has made me sloppier; I still prefer stick (though it is slower to put down). That being that, thanks for sharing.

When I weld tears in aluminum irrigation pipe much like your example, I always use a patch or band-aid as I call it. Irrigation pipe is not structural but has to contain pressure. I would not be able to bridge a gap as wide as that. Takes real patience for that.

Just got done building a crazy contraption lunchtime project made out of lawn chair tubing and old aluminum tent poles. 10 - 15 minutes at a time and most of the material is way less than clean. Most joints are not even coped out good so I have a lot of gaps with solid tube on one side and edge of tube on the other. I use mostly .030” aluminum MiG wire for fill. I have to build up the open edges like you did here and build a lot of bridges. I find that until you get a connection between the two tubes it is very unstable but once you get connected it balances out the heat. With thin tubing like this I also find that to aid in the heat transfer I have to go in ‘ surges ‘ more than just trying to be real low and slow. ( also because I am in a hurry ). Aluminum is cool and when you can weld it you can make anything

I think I learned more watching you make that ugly weld than the beautiful clean welds you normally make. Thank you for sharing. Clearly, none of us would want to bridge the huge gap in thin aluminum, but if you can do that, it seems like smaller gaps in thicker aluminum can take advantage of what you should us.
