hi guys, Wondering what you guys think of these welds I did last night. It's 5mm thick box, 8mm caps on the end of it. Using .8mm wire too. What's the little droplet looking things on the weld?
The glassy stuff? Thats just impurities floating to the surface, my guess is silica, it's very common.
Thanks Gaz Yes that's it. Makes sense. The one in the joint there. I did different to the ones on the caps. The caps I just ran straight beads. The joint however, I zig zagged up and down a couple mill. I guess like stitched it you could say.
Look very good Kim, I would try and sped up a little bit and don't weave/zig zag/aimlessly wander around for no apparent reason
Okay I had a reason. I thought it'd be stronger would I be better doing three beads then rather than weaving slightly
You leave my oak floor out of it Haha. I'm sure it's oak. It came out of our kitchen. My dad layed it for me. It never ever burns up I think it's been there for ten years.
If its purely a decorative end cap, I tend to do them downhand, especially smaller box like 50*3, but even on larger 6mm wall stuff. Get them nice and neat and requires virtually no clean up.
It did. I ordered some 30x8 flat bar which fitted perfect. I made the cap prodtrude slightly. (This is one reason I had it stuck up on the air) to make it do it I got two small bits of angle that were about 2-3mm thick, then put the cap on a magnet, angle either side. And then rested it in the hole. They're not decorative. It needs to be strong for hooks I'm welding on.
They are tidy enough and certainly not gonna be falling apart any time soon. As backpurge said don’t fall into the trap of weaving and waving about. A big fat weld performed with lower speed is quite likely to be a weaker weld than one put down straight and faster (all other settings being equal).
Thanks richard. I'll keep that all in mind. Got some more welding to do later. I'll see if I can get some pics
Nice welds One of the other mods who is more of a professional welder than myself once mentioned when welding box section you should go from middle of the straight to the middle of the next one and not corner to corner, it's a stronger way of doing the weld, something I did not know and probably not critical on hobby welding but I am always willing to learn the correct way.
