Tools used for automotive sheet metal repair include wrenches, screwdrivers, pliers, iron scissors and other common hand tools.
2.Body Repair Tools
Ball Hammer. Multi-purpose metal stretching tool used to correct bent structures, often used to work on initially molded body parts. Rubber Hammer. Used to lightly tap a steel plate without damaging the painted surface. Hammer.
A hammer is a tool necessary for restoring damaged sheet metal parts and is used to tap damaged sheet metal to roughly return it to its original shape, or to clean up damaged sheet metal when replacing it. PICK HAMMER. Repairs small dents, the tip of which is used to hammer the dent out from the inside, a soft, light blow to the center is sufficient, and the flat end of which is used in conjunction with a jacking iron to remove high spots and corrugations. Impact hammer. When repairing large dents, impact hammers are used for initial correction of the dented plate surface, or for machining the internal plate and reinforcing the associated areas. This situation requires a high level of force and does not require a smooth surface. Finishing hammers. After repairing a dent with an impact hammer, a finishing hammer is required to obtain the final shape. Top Iron. Usually the top is on the back side of the sheet metal struck by the hammer, and the hammer and top iron work together to bring down raised areas and raise low concave areas. Wedge Iron. Comes in a variety of shapes and sizes to match different panel shapes Use a pry pick. Used to get into limited spaces and pry up recessed points, comes in different lengths and shapes.
Second, common sheet metal repair welding equipment:
1. Inert gas shielded welder
Inert gas shielded welder is mainly used for welding high-strength, low-alloy steel body, as well as welding aluminum castings, such as cracked transmissions, cylinders, intake tubes and so on.
2. Resistance spot welding machine
Resistance spot welding is one of the most commonly used methods of welding overall. Resistance spot welding machine is suitable for welding high strength, the body does not deform the thin steel plate. Applications include roofs, doors, windows, sill plates and exterior parts.
3. Oxy-Acetylene Welder
Oxy-acetylene welding is a form of fusion welding. Mixed with acetylene and oxygen, it is ignited at the nozzle and melted as a high-temperature heat source (about 3,000 degrees Celsius) to join the coated electrode to the base material. Because it is difficult to concentrate the heat in one area, the heat affects the surrounding area and reduces the strength of the steel sheet. For this reason, automobile manufacturers do not recommend the use of oxy-acetylene welders for repairing damaged automobiles. Oxy-acetylene welders can also be used in garages for repairing damaged car bodies, heat shrinking, brazing and soldering, surface cleaning, and cutting non-structural parts.4. Brazing Machines
Brazing can only be used to seal structures. Brazing melts only non-ferrous metals during the welding process and does not melt the base material. Brazing is generally performed on automobile bodies (generally referred to as brazing with brass or nickel). Brazing is similar to gluing two objects together. The molten brass spreads sufficiently between the two layers of base metal to form a strong fusion zone. The impact bending strength of the weld is less than that of the base metal. During maintenance, it is important to note that only parts that have been brazed by the manufacturer can be brazed; other parts cannot be brazed.
5. Aluminum Welder
With the use of new materials in automobiles, many car panels are made of aluminum, which is more difficult to repair than steel. Aluminum is softer than steel. It is more difficult to process hardening and molding, and is easily deformed by heat. Aluminum body and auto parts are usually 1.5 to 2.0 times thicker than steel parts.
III. Body and Beam Alignment Equipment
Alignment equipment is a versatile body mounting system. A good alignment equipment should have various shapes of sheet metal tensioning tools, all-round tensioning force devices and practical measuring systems. Especially for integral body repair, the measuring system must simultaneously show the size and direction of misalignment at each reference point. Only with this equipment can the repairer accurately determine the sequence of tensioning and straightening, monitor the entire straightening process, and determine the effect of each pulling force.
