    Soft materials
    Several methods are available for soft materials like plastic films and paper. Razor blades, straight, or circular blades are being used. Some blades cut through the material while others crush the material against a hard roll. Those are similar to knives and cut the material into narrow strips, which may be called coils when being rewound. The cutting blades can be set to a desired width. Some machines have many blades to increase the options of cutting widths, others have just a single blade and can be set to a desired location. The slit material is rewound on paper, plastic or metal cores on the exit side of the machine.
    The process is used because of its low cost and high precision for mass production. Some machines have a program that monitors the blades and sharpens the blades often to maintain the quality and precision of the cut. Depending on the industry and the product that is being slit these machine can run between 10m/min (special metal webs) and 5000 m/min (paper making process). The machines can also incorporate extensive automation to precisely control material tension, automatically position the slitting knives, automatically align the cores onto which the material is wound and to reduce manual handling of the rolls.
    Examples of materials that can be cut this way are: adhesive tape, foam, rubber, paper products, foil, plastics (such as tarps and cling wrap), glass cloth, fabrics

    Hard materials

    For harder materials, such as sheet metal, blades cannot be used. Instead a modified form of shearing is used. Two cylindrical rolls with matching ribs and grooves are used to cut a large roll into multiple narrower rolls. This continuous production process is very economical yet precise; usually more precise than most other cutting processes. However, the occurrence of rough or irregular edges known as burrs are commonplace on slit edges. Also, the geometry of these rolls is determined by specific tolerances in addition to the type of material and workpiece thickness

    Machinery

    For metal coils, the slitter consists of three main parts: an Decoiler, slitter, and recoiler. The material is fed from the Decoiler, through the nip between the two circular cutting wheels (one on top and another underneath), and then re-wound in slit pieces on the recoiler.

    When the term “slitter rewinder” or “slitting machine” is used to describe the machine, the three parts are referred to as the unwind, the slitting section and the rewind. Slitter rewinders are normally used to slit plastic films, paper and metal foils. The unwind stage holds the roll stably and allows it to spin; it is either braked or driven to maintain accurate tension in the material. Some machines have a driven unwind which reduces the effect of inertia when starting to unwind heavy rolls or when the material is very tension-sensitive
    The slitting section has three main options

    Razor slitting, which is ideal for thin plastic films – the system is very simple and quick to set. Although the razor blades are low cost, they need to be frequently changed to ensure a good quality slit edge.
    slitting machine . Male and female circular knives engage to give a scissor cutting effect. This system is used widely on paper, films and foils. Although the knives take longer to position, they stay sharp longer than razor blades. The setting time can be reduced by using an automatic knife-positioning system.
    Crush cut slitting. A male knife runs against an anvil. The system works well with certain materials including non-wovens and foams.

    Super Missile Weld is a filler material that is like and used by a lot of fabricators and welders. One of the things people like about it is how the final weld turns out. You generally get nice looking beads with this filler.
    What a lot of welders and fabricators don’t know, is that “Super Missile Weld” is actually just a fancy name for 312 Stainless Steel. So, when you weld with Stainless Steel, you also need to remember about purging the backside of your weld if it is a critical part. If it is a static part, where 100% strength is not needed, you will likely be okay.
    So lets test it out and see what kind of results we can get.
