stitch welding - From my understanding, Stitch welding is not any harder than any other welding but it is quite time intensive. Some people do stitch welding via resistance welding, I can’t do resistence welding but I can do Mig. In any case, at this present time, I will have to say that it is not a project I can take on due my limited amount of time available.
pic of work - haven’t taken any pics yet but i will very soon.
Welder - currenly using an italian made MIG welder. It is good enough for most jobs except the welds are slightly thicker than a TIG. Some like it thicker but TIG could look prettier as it is easier to control. TIG is a better welder but a good TIG welder could go well into $1500 up to $2000. Perhaps later on.
Tubular/ gokart Chasis - I have not made yet and I don’t have a circular saw for the cuts. However, for this type of more advanced work, my friend who took mechanical engineering did many of those tubular chasis project at university and I will ask him for you how much it would cost. Would you be able to provide the raw material for the pipes? Do you have a schematic for the chasis?
Just for you… and for my bored gf watching… i went out and made a few welds.
:)… As I mentioned before, i’m not a pro … just I made welds on some scrap control arm lying around. I am doing some more welding this weekend for some brackets and I will post up those soon. I have done external wastegate pipe welding / rerouting to down pipe and other silly stuff… will post pics when i get a chance.
First pic shows the weld and the second pic shows the metal penetration on the reverse of the arm.
