Step 3Tack and weld
With the parts fitted together, I attached the earth clamp of my welder to a cleaned patch of the rail and tack welded the parts together. I then used the chipping hammer to remove the weld slag and checked that everything was still well fitted. When I was happy with it I proceeded to stitch weld the parts together fully.
Welding stuff this heavy properly would probably require more power than can be supplied by a basic 240v AC single phase stick welder. In this application however, the strength of the weld is not particularly crucial. I didn't have any electrodes other than these quite small ones on hand, so I invented the trick you see here in the second picture. It worked well enough for me, but I'm not a welder.

I've done that before, fast and dirty, and long arcing like crazy to burn the slag out. It works, but it doesn't make for great welds. But when thats all you have, and the job has to get done now, you do it.
