Automatic mesh welding lines For over fifteen years TJK Machinery Co, a leading Chinese manufacturer of rebar processing equipment, has supplied mesh- welding lines for:

Reinforcing mesh For reinforcing mesh to standard and • special mesh specifications using hot or cold rolled wire Welding system uses energising • cylinders to ensure high quality welds at high speed Patented welding circuit design can weld • 12mm diameter hot rolled deformed wires Cross wire feeding system, driven by • servo motor and equipped with a new feeding unit, ensures precise positioning of cross wires on the line wires

Fencing panel For fencing mesh in large batches, • using cold drawn wire, stainless steel or galvanized wire Line wire straightening system is suitable • for processing different raw material Industrial PC control system. Mesh sheet specification, production data and welding parameters can be easily input and • edited using the touch screen display High-speed mesh cutter has automatic start-stop control, synchronised with the welding line, at a maximum speed of • 120 times per minute Close-up of a mesh welding line from TJK ❍ ❍

Cage and security mesh For small diameter and small specification mesh in sheet or rolls, such as cage mesh •

Servomotor driven mesh-pulling system. Cross wire pitch is steplessly adjustable with high speed and high output • Mesh cutter has automatic start-stop control, synchronised with the welding line. The mesh sheet can be cut to any • length without overhang

End welding for cored wire lines Guild International has recently developed a new welding machine for joining coil ends on production lines producing cored wire. Known as the HMA Welder, this machine produces complete edge-to-edge welds on a variety of materials on all types of lines producing cored wire from flat strip.

The HMA Welder is designed to accommodate a strip with widths from 0.250" up to 3", and thicknesses from 0.008" up to 0.060". The HMA Welder is fast and easy to use. A shear cuts the coil ends on a bias, creating a precise edge for welding. The weld station is designed to use start and stop tabs allowing the weld to cover the entire strip width. This allows the weld to pass through the line and remain in the wire. The machine also features swing weld clamps for easy viewing, an XY micrometer slide for torch adjustment, and optional roll planisher. The entire weld process takes about 1-2 minutes, depending upon the size of the material. The welder is portable and compact, allowing it to be easily rolled between lines.
