According to working surfaces, tables there are two types: 2D & 3D Welding table

D22 tables: Hole diameter is 22mm; Hole spacing to each other is 75:0.05mm; Grid system 5ox5omm on table top.

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

According to hole size of tables, they are divided into 3 series-D16/D22/D28.

D28 tables: Hole diameter is 28mm; Hole spacing to each other is 100:0.05mm; Tgrid system 5ox5omm on table top. 

D16 tables: Hole diameter is 16mm; Hole spacing to each other is 5010.05mm; Grid system 5ox5omm on table top. 

Material of welding tables: Steel 8450 and Cast irons(HT300). And all plates are with reinforcing ribs on the underneath side.
