About the Laser Welded Saw Blade
Laser welding fuses each segment into the steel core instead of holding it with a braze layer, and we weld on a Dr. FRITSCH machine from Germany rather than a converted brazing rig. That is what keeps the blade intact when a segment meets rebar — the difference between finishing the pour and throwing a segment across the site.
Typical applications
- Reinforced concrete cutting — Wall saws and floor saws on columns, slabs and foundations where rebar is present.
- Demolition and opening work — Cutting door and window openings, stair wells and service penetrations in structural concrete.
- Brick, block and masonry — Where the same blade has to move between concrete and masonry without changing tools.
How to choose the right specification
- Segment height by workload — 10 mm for rental fleets and occasional use, 12 mm for general contracting, 15 mm for continuous production cutting.
- Core stiffness matters — Thicker, hardened cores resist deflection on deep cuts. Ask for the core thickness if you are cutting over 120 mm deep.
- Match arbor to the machine — 25.4 mm and 30 mm are standard; specify the flange diameter if you run a wall saw with a large flange.
Supply, packing and OEM
Welding runs on a Dr. FRITSCH laser welding machine from Germany, and every batch is checked by bending a sample segment and inspecting the weld zone; each blade is tension-checked after welding. Packing is colour box or wooden case, 50 pcs per size. Metric sizes and the packing language your market reads for Europe and Japan; 25.4 mm arbors and inch marking for Canada and North America. OEM covers core printing and box artwork.
Standard packing is color box / wooden case, minimum order 50 pcs per size per size, with mixed sizes accepted on a first order. Bulk orders typically ship within 25–40 days after deposit, FOB Shanghai or Ningbo — about 2.5 hours from our workshop in Danyang.
Most of this item ships to Canada, Europe, Australia, Japan, the Middle East and South America. Tell us the destination market and we match the sizes, thread standard, marking and packing language it uses — metric for Europe, Japan and South America, imperial where the trade still buys in inches, and carton copy in the language your customers read — then quote FOB, CIF or DDP against your order size.
