Standards for Manufacturing High Quality Welded Wire Mesh

The welded wire mesh is extensively used around our life. To keep the high quality of the welded wire mesh, we formulate complete manufacturing standard. We have four workshops to test the products quality in detail, they are: welded wire mesh panels workshop, gas welding workshop, electric welding workshop and dipping workshop. With high quality demands, our welded wire mesh panels own a good market.

The welded wire mesh panels workshop

• Manufacturing the welded wire panels products should be according to the production task list and the required size.
• Control the quality of the wires before producing the wire mesh. Informing the quality control personnel once the standard is not qualified.
• The tolerance of the mesh opening should be less than ±1 mm, and the size of the wire mesh should be less than ±2 mm.
• There is not missing welding and incomplete welding.
• The wire mesh should be neat and the diagonal should be within ±3–5 mm.
• There is not welding defect.
• The qualified rate is 98% for the domestic trade orders and 100% for foreign trade orders.

The gas welding workshop

• Manufacturing the products should be according to the production task list and the required size.
• The tolerance of the standard and the size should be within ±2 mm.
• There is not missing welding and incomplete welding. The welded point has no gap.
• The tolerance of the diagonal should be within 5–8 mm.
• The outer corner must be aligned before welding. The gap of the outer corner should not be more than 1 mm by the standard of the outer corner before hitting the corner.
• The tolerance should not be more than ±2 mm after welding.
• The tolerance of the angle for the bending welded wire mesh can’t be more than 1°.
• The qualified rate is 98% for the domestic trade orders and 100% for foreign trade orders.

The electric welding workshop

• Manufacturing the products should be according to the production task list and the required size.
• There is not missing welding and incomplete welding.
• The connecting of the wire mesh should be welded well. And the incomplete welding can't be more than 2 mm. The position tolerance should be within ±15 mm.
• The column cap connecting has two or more welded points. The welded point should be more than 10 mm. There is no gap between the cap and the column.
• The tolerance of the diagonal is less than 5 mm. There is not support frame under the 20 × 30 mm. The docking is neat and the angle is nice.
• The angle tolerance of the bend welded wire mesh can't be more than 1°.
• The qualified rate is 98% for the domestic trade orders and 100% for foreign trade orders.

The dipping workshop

• Manufacturing the products should be according to the production task list and the dipping color.
• The dipping should be neat, bright and clean.
• There is not leaching leakage, adhesion, flowing, pinhole and burning.
• There is no plastic leather breaking and deformation when we carrying the mesh panels.
• Polishing at least 80% welded skin.
• The qualified rate is 98% for the domestic trade orders and 100% for foreign trade orders.

The repairing workshop

• It’s not allowed to emphasize objective reasons or difficulties and shirk deliberately. And actively accept the maintenance work tasks from the production department.
• The defective goods can be used again after repairing.
• Be responsible to maintenance the equipment. To solve the problem in time. The repairing equipment should be on work during 24 hours when it’s busy on producing.
• Based on the safety operation standard, the workers should be responsible for the maintenance of big equipment and important machine.
• According to the producing task list, do the packing for packing material, packing standard and the label pasting position.
• The bending work is based on the manufacturing list and the tolerance could be ±1°.
