How to Customize Your Wedge Wire Screen Production Line?

Customizing an RKM wedge wire screen requires customization based on your specific requirements.

1. Identify the specific application for the wedge wire screen.

2. Screen size and shape (e.g., trough or triangular trough).
①Screen diameter =?
②Support wedge wire distance =?
③Support wedge wire size =?
④Slot =?

3. Determine the wedge wire shape: V-shaped for filtering large particles or U-shaped for finer filtration.

How to Choose a Wedge Wire Screen Machine?

Choosing the right wedge wire screen machine depends on the type of screen you plan to manufacture, screen diameter, slot opening, wire material, screen length, and required production capacity. RKM configures each wedge wire screen welding machine according to the customer’s actual product specifications rather than using one standard configuration for every application.

The following guide can help you identify the most suitable machine configuration for your production requirements.

Production Requirement	Recommended Machine Configuration	Key Consideration
Water well screen / Johnson screen	Cylindrical wedge wire screen welding machine	Screen diameter, length and slot opening
Flat wedge wire screen panel	Flat wedge wire panel welding configuration	Panel width, length and support rod spacing
304 / 316L stainless steel screen	Stainless steel welding configuration	Material grade, profile wire and support rod size
Small and precise slot opening	High-precision servo-controlled welding system	Required slot tolerance and minimum opening
Large-diameter wedge wire screen	Customized heavy-duty rotary welding system	Maximum screen diameter and finished screen weight
High-volume production	Automatic wedge wire screen welding line	Target output, screen dimensions and automation level

FAQ of Wedge Wire Screen Machine

What is a Wedge Wire Screen Machine?

The Wedge Wire Screen Machine (Wedge Wire Screen Welding Machine) is an optimal device for manufacturing wedge wire screens (Johnson tubes). Wedge wire screens are widely used in filtration, screening, and separation applications in industries such as water treatment, mining, chemicals, and food. This machine uses welding technology to secure wedge wires (with a triangular cross-section) into a grid structure, creating a high-strength, wear-resistant screening material.

How does the automatic wedge wire screen welding machine operate?

The machine uses continuous resistance welding where a surface profile wire (V-wire or wedge wire) is dynamically wrapped and resistance-welded onto internal support rods at every intersection, ensuring precise slot tolerances without manual tack welding.

What are the advantages of wedge wire screens?

1. The wedge wire structure enhances the screen’s resistance to pressure and impact.

2. The varying porosity of the wedge wire provides coarse and fine filtering.

3. The stainless steel wedge wire is highly corrosive.

4. Wedge wire screens are less susceptible to clogging.

5. They offer a long service life, reducing the cost of frequent replacements.

How much does a Wedge Wire Screen Machine cost?

The price of a Wedge Wire Screen Machine varies depending on customer specifications, electronic component configuration, and production volume. For a quick quote, please contact us!

Can this machine manufacture 5 MPa high-pressure welded Johnson filter strainers?

Yes. By adjusting the welding current, hydraulic clamping pressure, and using reinforced support rods, the line creates rigid welded constructions that meet international 5 MPa working pressure inspection standards for deep-well and industrial strainers.
