BT-11 GASLESS MIG WIRE 0.8mm (5kg)
- Bosseld Technology BT-11 Gasless MIG Wire
- 71T-11 is a self-shielding flux cored wire designed for single or multi pass welding having a smooth spraytype transfer commonly used on mild steels less than 3/4” thick.
- Easy general all position wire to use in the field where shielding gas is not practical.
- Limit to three passes will ensure properties on the mechanicals and weld deposit chemistry.
- Operates with no external shielding gas.
- The arc transfer is quite smooth and exceptionally low in spatter.
- The soft arc minimizes burn through on thin materials and in instances of poor fit up.
- A fast freezing slag facilitates welding in all positions.

Applications
71T-11 is ideal for those applications where the use of shielding gas is inappropriate and where charpy vnotch toughness is not of prime concern. This flux cored wire is well suited for butt, lap, and fillet welds on steels from 16 gauge through 1/2”. When welding on steels from 3/8” to 1/2” thick, a preheat of 325-375°F is strongly recommended. The .045” flux cored wire is not usually welded on steels greater than 3/8” thick, normally the 1/16” diameter electrode (or larger) is selected for these applications.
