btb.. i paid 180 for the total job (9 welds, 3 tops).. so who knows what kind of deal i got.//
Wirefeed welding without inert gas shielding is done with flux-cored wire. That is not MIG (Metal Inert Gas) welding, it is flux core welding, or FCAW (Flux Core Arc Welding). FCAW IS UNACCEPTABLE for most stainless applications.Henry Hill said:What some guys do for welding stainless is to use a MIG (Metal Inert Gas) (wire-feed or 'squirt welders', one handed welding) welder and a spool of stainless wire, however they are not equipped to use the inert gas to weld. Some MIG's like those for home use, do not facilitate a shielding bottle gas. You must specify that the equipment you want is TIG with inert gas. MIG, with gas is acceptable.
Backgassing is a poor term. The weld should be made using inert gas on BOTH sides of the weld.
Yuri_Rage said:If I were to go to a welding shop for work on my stainless brew equipment, I would ask the following questions:
Can you TIG weld stainless?
How much experience do you have with it?
Can you back-gas all of the welds on this job?
How much will it cost...and will a few homebrews get me a discount?
If you get anything less than a positive, knowledgeable answer to any of these questions, consider using another shop, or using weldless fittings.
yuri any thoughts on using co2 for my back gas purging or does it have to be argon?
