Quatrefoil Weld Spacer With Two Locating Slots

Core Features

Quatrefoil Body Geometry – The spacer is formed with a four-lobed configuration featuring rounded projections at 90-degree intervals. This geometry provides multiple attachment points for welding and increases the effective surface area for load distribution compared to circular or square designs.

Two Locating Slots – Two slots are formed through the spacer body, providing engagement features that maintain proper positioning relative to mating components. The slots resist rotational movement during assembly and subsequent service.

Weldable Design – The spacer is manufactured from weldable material grades with a geometry compatible with welding attachment to base workpieces. The lobes provide defined contact areas for welding.

Standoff Function – The spacer body provides a defined distance between stacked components, maintaining clearance for installation, alignment, or mounting of parts.

Product Characteristics

The spacer is manufactured with a quatrefoil body featuring four lobes separated by curved or scalloped edges. The lobes provide extended surfaces for welding attachment and distribute loads across a larger area. The two locating slots are positioned through the spacer body, dimensioned to accept pins, tabs, or other locating features on mating components.

The spacer height is defined to provide the required standoff distance between components. Material composition is controlled to meet specified strength and weldability requirements. Carbon steel grades are available for general applications, with material selection affecting strength and weld characteristics.

Surface treatment options include zinc plating with various chromate finishes, phosphate coating, and other finishes based on corrosion resistance requirements.

Application Scenarios

Structural Frame Assembly – Used in welded frame construction where spacers provide defined standoff distances between mounting surfaces and structural members, with the locating slots maintaining precise alignment.

Automotive Body and Chassis – Applied in vehicle assembly where spacers are welded to frame rails or body panels to establish fixed attachment points, with the quatrefoil shape providing multiple weld areas.

Enclosure and Panel Mounting – Used in equipment enclosures where spacers provide consistent spacing between panels and the locating slots maintain alignment relative to assembly features.

Fixture and Jig Construction – Employed in welding fixtures where the spacer provides consistent workpiece positioning and the locating slots engage with fixture features for repeatable placement.

Customization Options

Specifications and configurations can be adjusted based on application requirements. Body dimensions, lobe geometry, locating slot size and position, and overall height are customizable according to application geometry. Material grades include carbon steel for general applications and stainless steel for corrosion-resistant requirements. Surface treatments are selectable according to environmental exposure conditions.

Frequently Asked Questions

Q: What is the purpose of the quatrefoil geometry on this spacer?
A: The four-lobed quatrefoil configuration provides multiple attachment surfaces for welding. The lobes increase the effective contact area for load distribution compared to simpler geometries.

Q: What is the function of the two locating slots?
A: The locating slots engage with corresponding pins, tabs, or features on mating components, maintaining spacer position and providing anti-rotation during assembly. The slots ensure consistent positioning relative to assembly features.

Q: Are these spacers removable after welding?
A: The weld spacer is intended for permanent installation through welding. Once welded, removal typically requires destructive methods such as grinding or cutting.

Q: What welding methods are compatible with this product?
A: The spacer can be attached using resistance welding or other welding processes compatible with the spacer material grade and workpiece material. The lobes provide defined contact areas for electrode placement.

Q: What materials are available for weld spacers?
A: Material grades include carbon steel for general applications and stainless steel for corrosion-resistant applications. Material selection affects weldability and strength characteristics.

Installation Considerations

The spacer should be positioned with the locating slots engaged with corresponding features on the workpiece. The spacer body should contact the workpiece surface with the lobes providing defined weld areas. Pre-weld surface preparation should include removal of oil, grease, and oxide layers from the spacer contact area and workpiece surface. Welding parameters require calibration according to spacer material grade, thickness, and equipment specifications. For plated or coated spacers, welding parameters should be adjusted to account for coating effects on electrical conductivity. The locating slots should be fully engaged with the corresponding workpiece features to provide the specified positioning and anti-rotation function. Post-weld inspection should verify proper slot engagement and weld quality through visual examination.
