•The SANWZB Welding Table & Fixturing System comes in three hole‑diameter sizes: D28, D22 and D16.
•Each hole‑diameter series features dedicated matching modular fixtures.
•Fixtures for each series must correspond to the table’s hole diameter and shall not be cross‑compatible.
• Our welding tables primarily adopt Q355B (equivalent to S355JR / ASTM A572 Gr.50) as the standard base material.
• For higher‑performance requirements, hardened tool steel is available.
• SUS304 and HT300 cast iron can also be supplied upon special request.
Q355B steel plate applied, Surface Hardness: > 450 HV ( > 45 HRC).
Hardened tool steel applied, Surface Hardness: > 760 HV ( > 62 HRC).
We offer various surface treatment options to meet different application requirements.
For hardened‑tool‑steel welding tables, the plasma‑nitrided metallographic hardened layer can reach up to 760 HV, with base material hardness of 25‑28 HRC.
① Blackening (Phosphating)Surface treatment with high‑performance black phosphate coating for exceptional rust resistance. Base Material Hardness: HV 185 (HRC 12)
The surface is black and rust resistant, but has poor conductivity. Use a grounding point for optimal welding performance. |
② Hard Chrome platingThis electro‑deposited hard‑chrome coating resists moisture and oxidation. It creates a dense mirror‑like metallic surface against fixture‑caused abrasion. Surface Hardness: HV 800 (HRC 63), plating depth 0.08‑0.12 mm
Chrome‑plated surface treatment for rust resistance and metallic appearance. Excellent weld spatter resistance. |
③ Regular nitriding💎💎💎 Regular surface nitriding boosts hardness, offering great wear resistance and anti‑spatter performance. Surface Hardness: 450 HV (45 HRC), nitriding depth 0.25‑0.35 mm
The surface is dark grey to black hardened oxide. Excellent weld spatter resistance. |
④ Superhard nitriding💎💎💎💎💎 Superhard surface nitriding delivers exceptional wear resistance and superior weld spatter protection. Surface Hardness: up to 760 HV (62 HRC), nitriding depth 0.25‑0.35 mm
The surface is dark grey to black hardened oxide. Excellent weld spatter resistance. |
Code Structure:SWKXX‑XXXXX‑XX
Prefix Definition:SW = SANWZB Brand,K = Hole series
The SWK series ordering code consists of 7 fixed segments, covering hole size specification, product category, grouping, material type, serial number, grid layout and surface treatment. All models follow unified omission rules for standard ordering.
