Mig vs Tig

admin

So besides the appearance of the weld is there any structural benefits of mig vs tig?
Reply:Generally, no, provided both joints are properly prepared and both welds are properly executed.MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op
Reply:What kind of benefits are you talking about, and what do you consider "structural"Have we all gone mad?
Reply:One reason I believe some things require tig is because at the very start of a mig and stick, you have a cold spot where the filler metal is deposited. With tig you are melting the metal before you deposit the filler metal.Now keep in mind, this would only apply to critical welds. But as DesertRider33 stated, if a weld is properly done the shouldn't be a problem."Where's Stick man????????" - 7A749"SHHHHHH!!

Reply:There is a reason that structurally critical welds are not done with Mig. You dont have complete control and depth of penetration.I'm sure that some believe that with proper preparation this is a non issue but that is usually not the case.
Reply:Structural benefits, no.  Metallurgical benefits under some circumstances, yes.

Reply:Interesting. I did not know the MIG was that popular.Do you guys feel that stick welding will be phased out?
Reply:All types of welding have a time and place.I don't see any of them being discontinued any time soon.
Reply:MIG is VERY popular, most robots are MIG as well as major production welding. I have found that stick is really handy in dirty and windy applications such as in underground mines, the machines can be a lot more portable and the process can stand more wind and dirtier conditions. TIG is the "sexy" welding, roll cage tubing, aluminum boats, pipeline etc.As stated all of these processes have a very important role in joining metal together.
Reply:The short answer to your question is no there isn't really that much of a difference if both are done properly. This could degrade into a huge discussion of the finer points but since you are asking this question you're kind of a noob(don't feel bad we all were at one point) and you wont really benefit from know all the details and exceptions....yet. Stick isn't going anywhere. It's highly portable and versatile. It's a lot easier to drag around a stinger and a pouch full of rod than it is to lug around a suitcase feeder. It's also a lot easier to change between series of rods than it is to switch out the wire in a feeder.
