Core components
(1) Welding Table body
Material:
Q355 high-strength structural steel (tensile strength ≥ 355MPa, stronger than ordinary Q235 steel, suitable for heavy-duty welding).
Optional hot-dip galvanizing/powder coating treatment to improve rust resistance.
Structural design:
Thickened tabletop (usually 20 - 50mm to ensure high rigidity and anti-deformation).
Reinforcing rib support (to prevent sagging after long-term use).
Surface treatment:
Precision milling/grinding (flatness ≤ 0.1mm/m²).
Optional hardening treatment (such as flame quenching to improve wear resistance).
Hole system:
Standard D28/D16 hole arrays (28mm or 16mm pitch grid holes, compatible with European and national standard fixtures).
M12/M16 threaded holes (for high-strength locking).
Size specifications:
Common sizes: 1000×1000mm, 2000×1000mm, 3000×1500mm (customization is supported).
(2) Welding Fixtures
Positioning fixtures:
Dowel Pins - to ensure datum alignment.
V-Blocks - used for fixing pipe/shaft workpieces.
Angle Plates - to achieve precise welding from 0 - 90°.
Clamping fixtures:
Toggle Clamps - manual operation, quick locking.
Hydraulic/pneumatic fixtures - suitable for automated production lines.
Magnetic Clamps - quickly adsorb ferrous workpieces.
Auxiliary tools:
Backstops - to prevent welding spatter from damaging the tabletop.
Adjustable Rollers - used for positioning long workpieces.
