What is flux core MIG wire used for?

What is flux core MIG wire used for?

A flux-cored wire is optimized to obtain performance not possible with a solid wire. For many welding applications like vertical-up welding, flat welding, welding over galvanized, or welding hard-to-weld steels, a flux-cored wire can do it better and faster.

Can you mig weld stainless steel with flux core wire?

Flux-cored Arc Welding is widely used in welding Stainless Steels. There is minimal problems with this process and it is actually recommended when you need to weld thick plates in a short period of time. The weld deposit rates are significantly higher than other welding processes.

Can I use solid wire in a flux core welder?

Solid wire, self-shielded flux-cored wire and gas-shielded flux-cored wire all work well — provided they are applied correctly.

How do I choose flux core wire?

Wire selection 030-inch diameter is a good all-around choice for welding a wide range of metal thicknesses. For welding thicker material at higher total heat levels, use . 035-inch wire (or . 045-inch wire if it’s within your welder’s output range).

What metal can you weld with flux core?

There are many advantages to using flux core welding, most notably its ability to be used in all positions when equipped with the right filler metal. Flux core can be used with a variety of metals, including stainless steel and some nickel and steel alloys.

Why are my MIG welds Sooty?

Excess soot can be caused by: 1.) too long of an arc length, either by operator stick out, or excess voltage. Incorrect Gun angle, next time you are playing around with some scrap, vary your gun angle, you can actually move the soot from one side of the weld to the other just by changing gun angle.

Why does my MIG welder spit?

A common cause of MIG welding spatter is excessive speed or irregularity with your wire feed. Spatter occurs when the filler wire enters the weld pool. The solid wire melts at a rapid rate due to the extreme heat. As it melts, the filler wire turns into a liquid form, creating the pool.
