Reduce the Deformation of Sheet Metal Welding With the Help of External Force

sheet metal china | sheet metal fabrication china 1 Water Cooling Block

Many techniques can be used to control the welding deformation of special welding workpieces. For example, in thin plate welding, the use of water-cooled blocks can take away the heat of the welded workpiece. The copper pipe is welded to the copper fixture by brazing or tin welding, and the circulating cooling is carried out through the water pipe to reduce the welding deformation.

2 Wedge Block Locating Plate

“Locating plate” is an effective technology to control welding deformation during butt welding of steel plate, as shown in the figure. One end of the positioning plate is welded on a plate of the workpiece, and the other end wedges the wedge block into the pressing plate. Multiple positioning plates can even be arranged to maintain the positioning and fixation of the welded steel plate during welding.

3 Thermal Stress Relief

Except for special cases, it is not a correct method to eliminate stress by heating. Welding deformation shall be prevented or reduced before the completion of workpiece welding. click here to contact JIATONG

Process Analysis of Sheet Metal Structure Design

Sheet metal processing is a comprehensive cold working process for sheet metal, including shearing, punching, cutting, folding, welding, riveting, etc. its remarkable feature is that the thickness of the same part is the same. Sheet metal is generally some sheet metal through manual or die stamping to produce plastic deformation to form the desired shape and size, and can further form more complex parts through welding or a small amount of machining. For example, chimneys, iron buckets, oil tanks, oil pots, ventilation pipes, funnel-shaped, etc. commonly used in families, as well as electrical cabinets, shells of various special equipment, computer cases, automobile shells, etc., are all sheet metal parts. There are no specific structural requirements for sheet metal parts, which are generally designed according to the needs of products. On the premise of meeting the functions of products, the designed structure should be easy to process, low cost and beautiful. For...

Design Criteria of Sheet Metal Structure

According to the problems encountered in the actual machining process, the problems needing attention in the structural design of sheet metal are discussed from the following aspects, and the corresponding design criteria are given. Selection Criteria of Sheet Metal Materials Sheet metal is generally used for the installation of equipment shell and electrical circuit, so it is very important for the selection of sheet metal. Proper selection is not only conducive to processing, but also can reduce the cost on the premise of ensuring the strength. (1) In order to ensure the material utilization rate and the minimum number of die changes in bending, the thickness specifications of plates on the same structure shall not exceed three at most. For structures with high strength requirements, the method of pressing reinforcement on thin plates can be adopted; (2) It should be avoided that the unfolding size of parts is equal to the outline size of raw materials: the shape of plate...
