FAQs

Can I use flux core wire to weld body panels? ›

Welding body panels using flux-cored welding machines is possible, but not recommended. With FCAW the body panel will be more prone to burn through and warping due to the excessive, localized heat.

I suggest getting a unit that can use gas or that gas can be added on later. For thin sheet aka car body panels I would go with the gasless mig (the wire produces its own gas via the flux it is treated with, so you have to get gasless mig wire which is more expensive...).

Both have their own unique characteristics and are used for different purposes. Flux-cored wire is known for its ability to weld in windy conditions and in areas without a clean environment. On the other hand, solid MIG wire is preferred for its smooth and consistent welds.

The wire selection here becomes even more important, so far the Select 700GS was the perfect match for this kind of job. This wire is specifically designed to be worked on thin metals, the diameter to go for would be . 030” or 0.8mm. Running this on 30-40 Amps and 100-120 IPM wire feed speed should do the trick.

Key Factors In Choosing a MIG Welder for Car Body Repair. For sheet metal welding on car bodies, a 120-180 amp welder is typically sufficient. Higher capacity 240-300 amp welders may be needed for welding thicker car frames and components.

MIG welder is arguably the best welder for autobody. It employs a shielding gas and filler material in a wire fed directly through the welder. MIG is faster than most other welding methods and much easier to learn.

I choose TIG over MIG any day due to the ability to control how much heat is being put into the work as well as the advantage of less clean up. With TIG you wont have huge tacks to grind down smooth because you get to control how much filler is added in the weld. Also, you get better penetration with TIG.

In terms of weld quality, both stick and flux-core welding heavily depend on the welder's skill. All else being equal, stick welding will generally produce a slightly better weld, but both are more or less comparable.

Flux-cored welding 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).

Welders will debate whether flux core welding or MIG welding provides a stronger weld until the end of time. The truth of it is that they are ultimately pretty similar. For most applications, both methods will provide a strong weld that will hold what it needs to.

Why can't you weld rebar? ›

Because rebar is not as closely controlled in terms of metallurgical quality, the average rebar you pick up at a contractor supply house or big box home improvement store isn't high enough quality to be welded effectively. Welding-quality rebar is typically marked with a “W”.

To weld medium-thickness metal up to 1/2" or 1/4", you will need a 200-250 amp rated welder with 220V input. These machines have enough power to join thicker metal with ease and our recommendation is YesWelder MIG-205DS.

Whenever possible, select steel within the "normal range," these include AISI-SAE 1015 to 1025 steels with 0.1 percent maximum silicon and sulfur content under . 035 percent. Selecting these steels will make the stick welding process easier since they can be welded at fast speeds with minimum cracking tendencies.

Ultimately, the choice between MIG and TIG welding for auto body repairs will depend on the specific needs of the repair and the experience level of the operator. In general, MIG welding is a better option for larger or more utilitarian repairs, while TIG welding is a better option for smaller or more intricate work.

TIG welders are also commonly used in automotive and car restoration applications, especially for applications that require precise and high-quality welds. TIG welding is often used for welding thinner materials, such as body panels, and for situations where aesthetics are particularly important.

Metal Inert Gas (MIG) is arguably the best welder for autobody. It employs a shielding gas and filler material in a wire fed directly through the welder.

Which Metals Can Be Welded with FCAW? Flux cored arc welding works well with most carbon steels, cast iron, stainless steel and hard facing / surfacing alloys. However, nonferrous exotic metals, such as aluminium, cannot be welded using this welding technique.
