1. Carbon steel
2. Stainless steel
3. Aluminium
4. Cast iron

Of them, carbon steel is the widely used material for making a welding table. Carbon steel is an alloy of iron and carbon. Next, the best option is a Stainless Steel welding table. It has chromium content which provides corrosion resistance to the table. The higher is the chromium content in the stainless steel, the better will be the corrosion resistance and shiny surface.

Cast iron mainly grey cast iron acts as an excellent surface for welding. Its high vibration damping capacity absorbs any vibration that occurred during the process and keeps the work stable. Also, it doesn&#;t allow any weld spatter to stick on it ensuring clean welding. 

For welding of carbon steel workpieces, a welding table made of carbon steel does the work well. For welding of stainless steel jobs, an aluminum-copper alloy that is non-ferritic is suitable in making a welding table. In the case of stainless steel parts, ferritic surfaces are to be avoided. Thus, if carbon steel is used, the material sticks to the welding table and causes pitting and scratches. An aluminium-copper table has high tensile strength and low surface hardness so that there is no possibility of scratches or pitting. It has high thermal conductivity to dissipate heat quickly and also prevent spatter from sticking to the welding table.

1. 3D Welding Fixture

    3D Flexible Welding Table & Fixtures is a newly widely-used welding tool, which enjoy modularity,

standardization & reusability. Mainly used for welding clamping & locating of steel structures and other

product assembling & fabrications.It replaced traditional dedicated fixtures with its high efficientcy /

precision / convenience.

2. Product features & classification

   a. According to working surfaces, tables has two types: 2D & 3D Welding table.

   b. 2D Welding table has only one working surfaces and been precision machined.

        3D Welding table has 5 precision machined working surfaces (1 top+4 side surfaces).

   c. According to hole size of tables, they are divided into 3 series&#;D16/D22/D28.

   d. D16 tables: Hole diameter is 16mm; Hole spacing to each other is 50±0.05mm;

        Grid system 50x50mm on table top, Plate thickness is 14mm.

   e. D22 tables: Hole diameter is 22mm; Hole spacing to each other is 75±0.05mm;

       Grid system 50x50mm on table top, Plate thickness is 18.5mm.

   f.  D28 tables: Hole diameter is 28mm; Hole spacing to each other is 100±0.05mm;

       Grid system 50x50mm on table top, Plate thickness is 23.5mm.

   h. Material of welding tables: Steel Q345(Mn16) and Cast irons(HT300).

      And all plates are with reinforcing ribs on the underneath side.

3.Application fields

   a. Engineering machines  b. Rail transportations  c. Vehical & car body  d. Marine & shipbuilding

   e. Cabinet  6.Sheet metal   f. Equipment manufacturing  g. Industrial pipes  h. Furniture making etc.

4. Compared with traditional dedicated fixtures

5.Choosing and using of Welding fixtures

   a. Welding tables are chosen & used according to the size, shape and weight of weldments.Sheet

metals and small steel structures are  mostly chosen D16 series welding tables to use. D28 series

welding table are mostly for big steel structures and heavy-duty machinery industry.Yahanda suggest

choosing D22 series welding tables for weldments which sizes & shapes are variable and changing

greatly.

   b. Fixturing tools are chosen to use according to weldments' shapes & sizes. Complex weldments

use more fixturing tools relatively, and less for simple ones.
