MIG gun nozzles question

admin

Ok, im not a welder by trade, i work in fabrication but i don't do a lot a welding and never learn at school, i prefer explain this before ask my question!Today at work i had to do some ''boring production MIG taking'' a bunch of same shape assembly in a jig, so i had to use non stop a MIG welding machine!A bit of spatter on the metal pieces and on the gun tips and the nozzle are normal, a lot is due to a bad setting, thats basic stuff i know, but due to the fact that im not a good welder i was probably doing something wrong, maybe during 1h30 of production MIG taking my nozzle was full of spatter, i had to stop and clean it maybe 7 ot 8 times, one time the spatter make a bad shortcut with the nozzle and the tip, so my nozzle start to melt!anyway i hated to do those rough and fast job but i had to do it!After during my lunch break i went to the stainless departement looking at the TIG welder (i like just look at their job during my lunch) and i had an idea!i imagine if the MIG nozzle were made of the same kind of ceramic of the pink nozzle on TIG torch, MIG nozzle make with ceramic could not work great do you guys think ?it seem like nothing stick on those nozzle (even if TIG don't spatter)Calculator > Bevel Square
Reply:Not a bad ide on the surface of things They exist. You can buy them,  But they're hideously expensive. Lots of time and labor required to make ceramic parts, especially silicon nitride. So they're confined to robot applications mostly. The main issue as I see it: you have to consider the amount of abuse that happens to MIG guns, at least in the hands of human weldors. They wouldn't survive two days at my company. (some of the night shift crew are real boneheads.)You'd invariably end up with a layer of spatter no matter what material you used. You would have a lot harder time cleaning a ceramic nozzle without chipping or breaking it. Copper is forgiving of some of the more...shall we say...aggressive methods of cleaning. For example, I like to run my die grinder around the inside. I sure as hell couldn't do that with ceramic.Copper is also a great heat conductor unlike ceramic, so it stays cooler and cools off faster.The reason copper isn't used for TIG nozzles is, if you tried to use the "walk the cup" technique, the arc would short to the nozzle and weld it to your work piece.

Reply:yes i've used a small pot of anti spatter to dip the nozzle, its did the job spatter are still there after 8 or 10 minutes, my question was mainly about saying my idea of ceramic nozzle to see if there already exist or just to see if its could be possible!Calculator > Bevel Square
Reply:Hello LayoutMan, Josh spelled out it very completely with regard to why ceramic probably wouldn't be a very good choice. Cost, breakage, heat, stickiness, that about sums up why ceramic wouldn't be very serviceable. Good luck and regards, Allanaevald
