    So I had my frame hardtailed tig, can I have things like pegs, mounts, etc done by mig? A friend of mine has one, would save me time and money.

    Thx, Was just curious about strength.
     
  3. Strength comes from the weld being done properly. Search MIG vs TIG in the google search bar at the top of the page.

    Do people say use tig then because your less likely to do it improperly?

    TIG is a slower process. As you weld you can see the depth of penetration of the weld. This I suppose makes it inherently safer because you can confirm the quality of the joint as you weld it. That is unless a crack develops. Either way, you need to know what you're doing.
     
  6. the hard tail you bought was probably done with MIG!!
     
  7. MIG and TIG are just different disciplines. Neither is inherently better than the other. To answer your question, yes, you totally can. People get huge boners for TIG because it will ultimately create a cleaner/nicer looking weld. However, you can make really nice welds with a MIG torch.

    TIG is better for thin aluminum.

    TIG is cleaner and used for food grade stuff.

    Etc.

    However, for a damn motorcycle hard tail, MIG is great! How do you think Yamaha welded together your frame in the 70s? Definitely not TIG, it wasn't even invented yet.
     
  8. Yeah kinda.. You can make a decent looking MIG weld that has no penetration at all. A good looking TIG weld is probably a strong weld. If your buddy knows what he's doing with the MIG welder, you have nothing to worry about.

    Any reason why a frame couldn't be welded with oxy/acetylene?
     
  10. No, oxy acetylene is fine if you have the skills/experience and create a good weld.

    I've read that a lot of small aircraft frames are done with O/A. Also that if TIG is used, they bust out the oxy acetylene afterwards to normalize the welds with a rosebud tip.

    I know of a few race cars that were brazed together.

    Here is a good web site to learn and undertand the differences between Mig,Tig, and Arc welding

    I'm glad to know Oxy/Acetylene will work.I want to weld some gussets in the frame of my XS2 to stiffen it and also the swingarm.I'll probably tack the gussets in place with my torch then get someone more skilled to do the real welding with whatever method they prefer.I'm assuming the frame and swingarm are mild steel?

    as a "shade tree" welder, some Certs, some employment, some training, etc., a large difference in the processes mentioned is "heat affected zone" that is how much and how far is the heat of the welding process transferred. This heat can and will affect the temper (strength) of the base metal.

    Old school rules -oxy welding has the greatest heat transfer, Mig next and Tig least.

    Tig IF you have the welder and talent and experience is the "stuff" BUT as previously stated MIG is such a close second that even if I had the money for a TIG welder and the time to gain experience I would easily have better ways to spend both and would stick to MIG.

    The skill it takes to do good Oxy-Acet welding transfers to the skills needed for TIG. Most anyone can MIG weld in 5 minutes . . but the quality is suspect. So like others have said, its not the type of welding, its who is doing it and how it was done. I enjoy gas welding, but wouldn't use it for sheetmetal. However, I have seen it done on sheetmetal that would just amaze you. So . . its the skill level. I used to teach welding in HS.

    I'm in aircraft maintenance so I'll probably ask a certified aircraft welder to do it for me.Fabric covered aircraft usually have a tubular mild steel frame that is probably pretty similar to a motorcycle frame.

    Probably every structure on the aircraft is made with 4130.

    I edited my response . . I meant to say MIG instead of TIG for learning quickly.
