hey im trying to weld a rail but the welder i got isnt strong enough to weld the steel piping together. do any of u guys know how strong a welder hsa to be to weld steel pipes to make a rail?
Are you using an arc welder? If so just put it on like 110-120 and use a 6011 rod. If its mig, put the voltage a couple notches from max, and wire speed at whatever it needs to be.
yea, you really cant fuck up mig welding. A cheap craftsman 200 dollar welder is strong enought to weld 1/4 inch steel, which is plenty for any park rail.
teach urself. there's not much to it, although it'll likely take you a few tries. If you want just get someone to show you the basics and you can pick it up..
^Im in the same boat, I am at school for mech engineering right now, and have been taught by another student the basics of welding. Now i just practice on random metel. Hopefully gonna get around to purchasing a cheep welder soon.
grind and polish the ends put like a 20 degree chamfer on it then sue about 120 and grid it to a smooth finish should do the tricck, it took me lie 2 months to really get good at welding. and if worst comes to worst use oxy-acetline its cheap and works as good, not to mention super easy
ya it prob takes a long time to become really good at it just like any other trade but does it take long to just get the basics down? like welding rails? do pipes off like chainliink fences work good for making rails?
pipes from chain link fences need to be shorter then 6 feet to hold up under load unless properly supported, and yes oxy-ace can be welding too its accually the easyiest to control
if you dont want to die, when you are over the weld try nou to be directly over the smoke,second a divise for spray painting, like a resperator helps, third take your time and do it in sections, lastly make sure its sanded to a good bare metal, as much as this sounds like a lot it will save your life
