no man thats mig

 

[redsox985]

Mig as in solid wire with shielding gas or mig as in flux cored wire. Because it looks like you're using solid wire (true mig) with no gas. Did you chip the slag off (flux cored)? Maybe, did you weld over the slag in many layers (flux cored)?

 

[AnderBlast]

im using fiux cored wit no gas
but there is no slag to chip off when im finished welding

Well they should be. You can only do one pass, then you have to remove the flux/slag. Then make another pass. If you weld on slag, the weld will have terrible penetration and be weak as hell.

Same for arc welding.

slag as in the white stuff thats left after i do a bead

 

[Rustydog2010]

Yea like this.

With slag:

Slag removed:

 

[AnderBlast]

ya man thats the stuff i do clean it with a wire brush after i do a bead

 

[Rustydog2010]

Just make sure you get rid of as much as you can, and make sure that your bead is not to thick. I aim to make the bead about 10-15mm wide. It looked like yours was more like 25mm. But that could just be the picture.

cheers man i just had a look on mig-welding.co.uk wrere ya got thoes pics theres a good few tip on welding with flux cored wire so il have to put them into practice and see if my welds improve

 

[Rustydog2010]

Sweet as mate, let us know how it goes. Will be interesting to see this beast in action.

Not to get overly technical but to avoid confusing noobs-

No, it's not MIG, its FCAW, or Flux-Cored Arc Welding. Wirefeed with a flux core wire, reverse polarity. MIG stands for Metal, Inert Gas. For this you need a solid core wire, and a cylinder of gas, usually a Co2/Argon blend.

will do man
and as for the technical terms and all that im not really into them its all the same to me lol

Over here (and it might be the same where you live) we learn by the school to call it MAG welding instead of MIG, same as you discribed using a gas. Not 100% but i think MIG is the old way a saying it (correct me as I might to be wrong).

I have lost marks in exams for saying MIG instead of MAG.

Metal Active Gas to the best of my memory.

well havent been on in a while the screen in my laptop is broke
iv made some progress since my last post and ive also changed my engine choice im no going for a 350cc 4 stroke honda engine as the kart is getting bigger and heavier im uploading some pics a the min so il post them when there done

 

[AnderBlast]

heres the pics

[landuse]

Thats coming along nicely. How much does all of that now weigh?

 

[bighead]

I like the square sprint dirt track looking top of your cage. It may be a smidging to tall though. Nice job.

 

[saebajacaptain]

For doing this at home, its pretty well done. I am interested to see what the rear half will look like being as it seems you need more triangulation centered around the rollcage/cockpit area. Shame the majority couldnt have been done in round tubing, but i would imagine this is a budget build and youre doing with what you have. have you thought about getting a steering rack and making it double a-arm long travel in the front? would handle much nicer, though a little more work. Or independent chain driven rear suspension? And youre beginning weld was looking rather horrid, but the last close up looked much improved! keep this updated im interested in seeing where it goes.

 

[AnderBlast]

cheers lads its gettin there

landuse i havent weighed it yet but i can lift it easily

bighead its not actually that tall it just looks really tall in the pics

saebajacaptain

there will be more triangulation going into it when i get more supplys
i using the single a arm because its all from my quad in the future i might modify it not sure yet
ya the welds have improved a bit i bought some better quality flux cored wire and its alot better to weld wit so it makes a difference
