Spot welding (or resistance spot welding [1]) is a type of electric resistance welding used to weld various sheet metal products, through a process in which contacting metal surface points are joined by the heat obtained from resistance to electric current.
The importance of the high-precision surface plate was first recognised by Henry Maudslay around 1800. He originated the systems of scraping a cast-iron plate to flatness, rubbing marking blue between pairs of plates to highlight imperfections, and of working plates in sets of three to guarantee flatness by avoiding matching concave and convex ...
A spotface or spot face is a machined feature in which a certain region of the workpiece (a spot) is faced, providing a smooth, flat, accurately located surface.
Roll forming lines can be set up with multiple configurations to punch and cut off parts in a continuous operation. For cutting a part to length, the lines can be set up to use a pre-cut die where a single blank runs through the roll mill, or a post-cut die where the profile is cut off after the roll forming process.
A spot plate, also called a reaction plate, color test plate, [1] or spotting tile (British English), is a laboratory tool made either from ceramics or plastics. [2] Each plate consists of many cavity-like depressions in which only small amount of reactants can be added at a time. [ 3 ]
Side view of a beam with two weld access holes cut into the web. Also the flanges have been beveled in preparation for welding. The weld access hole or rat hole is a structural engineering technique in which a part of the web of an I-beam or T-beam is cut out at the end or ends of the beam.
Die Back Plate:This plate prevents the hardened Die inserts penetrating into bottom plate. Guide Pillar & Guide Bush : Used for alignment between top and bottom halves of the press tools. Bottom plate:It is used to hold bottom half of the press tool with press slide. Stripper plate: it is used to strip off the component from punches.
