how can i improve in my welds? lincoln sp 125 plus wire,

 

clean the metal..was that with flux core wire?

 

i dont know. how do i check?

 

looks like flux. do you use a shielding gas? those arent to bad man.

 

what is a shielding gas?

 

Shielding gases are inert or semi-inert gases that are commonly used in several welding processes, most notably gas metal arc welding and gas tungsten arc welding. Their purpose is to protect the weld area from atmospheric gases, such as oxygen, nitrogen, carbon dioxide, and water vapor. Depending on the materials being welded, these gases can reduce the quality of the weld or make the welding process more difficult to use.

 

tig boy at least link it from your source, lol

 

you need to work on consistency when your welding. look listen and feel for consistency. that usually means the well will be totally consistent. judging from your welds penetration that was your problem... but you would have an easier time welding a decent weld on an easier better machine like a gas mig welder not a flux core mig welder like the current one your using.

 

ok lol, wikipedia. but I didnt need that, just to lazy to type that mess.

 

I've definetly seen worse.

 

Well a buddy of mine used co2 as a Shielding GAS.

 

Yah, Mig is usually 75percent argon, and 25 percent C02

and for tig i think they usually use 100% co2, or u can use 100% argon..

 

i just need to grind it smooth and i have no leaks i checked with putting water inside

 

 

 

Looks like mine on Flux

 

****.. Just dont grind down TOO much.. Just kinda smooth out the high spots etc, dont try to make it flush.

If you think it looks ugly, just get some headerwrap and wrap that SOB

argon only for most people. CO2 isn't used by many.

 

That's not the end of the world. It looks to me like you have too much wire stick-out. I know that crap wire spatters alot, but by the size I would say keep the nozzle closer to the work.
A good technique when heat brings excessive spatter is to bevel the tubing a little
with a grinder, and turn the heat down. You can try to turn it down quite a bit, and whip the puddle a bit. Keep the nozzle really close to the weld.
Shielding gas and mig wire will give better results next time. Not sure if you can with your welder, thought you might have the ability to hook-up a small gas cylinder.
Good luck.

I really wouldnt bother to grind it down. You may lose the weld strength if you do.

Nice. It's got character. My downpipe looks similar. Not as many mitre cuts, though.

 

Its not gonna win any beauty contests, but it'll get the job done. Nice job on the DIY!
