The flare fitting is used in a similar way but instead of the welding process

Flare fittings, also called flare caps, are a special type of compression fitting commonly used in welding, pipe welding, piping and other forms of fabrication work, including sheet metal manufacturing. Flare fitting is generally referred to as a sheet metal forging process, and is often a cold forming process. In the welding process, the work piece is heated and the molten metal is forced into a hole in the work piece, forcing it to solidify into a shape that can be welded. The flare fitting is used in a similar way but instead of the welding process, the work piece is fed a filler material which is hot enough to melt into a molten state and then hardened by heating and shrinking under pressure. These fillers are then used as a filler for the weld puddle. This procedure is sometimes called "hot forming" or "cold forming" of weld puddle because the filler materials that are used are typically cool enough to dissolve and become part of the weld puddle.

The reason why the filler material is part of the weld puddle is so the filler can be worked into the weld puddle and make the puddle of hot molten metal in a controlled fashion. During the forging process, when the filler material is formed within the work piece, the filler metal is allowed to melt into the puddle as the work piece moves through the welding arc and the filler metal is not forced out of the work piece. During the cold forming process, the filler metal is made to remain in the puddle as the work piece passes through the arc. The filler metal in the filler metal can then be easily removed when the weld puddle has cooled and hardened. In the heat forming process, the filler metals can be easily forced out of the puddle by heating and shrinking. When the weld puddle is cooled and hardened, the filler metal is left in the puddle and cannot be removed from the puddle.

Flares are commonly used in fabrication work where metal sheets need to be welded together, where metal pipe is needed to carry fluid, and also when welding sheet metal. There are also many types of welding that use flare fittings, such as cold forming, hot forming, gas welding, plasma welding, electrical welding, gas tungsten arc welding, sheet metal welding, MIG welding, arc welding and TIG welding. There are also many types of mig welder that use flare fittings. to provide a better welding experience for welders that do not have experience welding. flare welder welding.
