Pressure Electrodes TRIZ Cases
- Concentric Electrode Spot Welding to Reduce Zinc-Induced LME
An in-line two-step weld uses a concentric electrode to purge zinc coating before spot welding, reducing LME cracking in Gen3 steel.
- Welding Electrode Sliding Member Structure for Thermal Expansion Wear
A thin-wall sliding member with an air passage relieves thermal expansion force, reducing guide-hole wear and guide pin misalignment.
- Hybrid Resistance Welding Electrode for Dissimilar Metal Joining
A pin-and-collar electrode improves heat balance in aluminum-to-thin-steel spot welding, reducing expulsion, cracking, and penetration.
- Convex Copper-Alloy Electrode Tip for Stable Spot Weld Appearance
A convex copper-alloy tip with tuned inner diameter and bottom thickness limits deformation and heat rise while improving spot weld appearance.
- Welding Electrode Sliding Member Structure for Thermal Expansion Wear
A thin-wall sliding member with an air passage absorbs thermal expansion, reducing guide pin wear, misalignment, and welding accuracy loss.
- Aluminum Spot Welding Emboss Geometry for Stable Nugget Formation
A preformed circular emboss guides nugget shape in aluminum spot welding, improving joint strength while reducing electrode contact and adhesive interference.
- Spot Welding Electrode Angle Correction to Prevent LME Cracking
Universal-joint electrode tips correct tilt during spot welding of galvanized high-strength steel, reducing tensile stress and LME cracking.
- Textured Electrode Tip Reconditioning for Oxide-Breaking Spot Welding
A patterned reconditioning tool imprints electrode tips to break oxide layers, lower resistance, reduce dressing downtime, and keep weld quality stable.
- Adjustable Cooling Pipe Positioning for Resistance Welding Electrodes
A movable cooling pipe keeps water flow close to the cap tip, preserving electrode shape and welding quality across shank length changes.
- Grooved Spot-Welding Electrode for Oxide Film Contact Stability
Grooves or blind holes on the electrode tip break oxide films, stabilize current flow, and preserve weld quality after dressing.
- Dissimilar Metal Resistance Joining with Discontinuous Abutting Parts
A discontinuous abutting part boosts resistance heat to melt aluminum against steel, enabling reliable mass-production joining without inserts.
- Magnetic Spot Welding Electrode for Surface Spatter Suppression
A magnetic unit on the welding electrode creates Lorentz force to redirect nugget growth and suppress surface spatter in ultra-high-strength steel welding.
- Dual-Ring Joining Structure for Bending-Resistant Metal Joints
Two axially spaced joining sections distribute bending stress while cutting burrs, spatter, and joining energy in metal assemblies.
- Resistance Welding Contact Geometry to Reduce Plating Adhesion
Curved plate-electrode contact areas stabilize resistance welding, reducing plating adhesion, defects, and electrode wear.
- Steel Cord Welding Electrodes With Flat Contact Areas for Stable Welds
Elongated flat electrode areas stabilize contact resistance in butt welding of twisted steel cord ends, improving weld repeatability.
- Dissimilar Metal Plate Joining via Selective Resistance Heating
Selective resistance heating keeps the higher-resistivity plate below its melting point while melting the other plate to form a strong intermetallic joint.
- Welding Gun Integrated Clamp Arm Wedge Mechanism
A welding gun integrates a clamp arm driven by an inclined section that converts linear displacement into rotational clamping force.
- Resistance Welding Electrode Valve Body for Gas Control
A resistance welding electrode uses a movable valve body to direct compressed air flow only during the welding process.
- Welding Electrode Dynamic Sealing via Elastic Ring
Elastic ring seals guide pin in welding electrode, preventing cooling air leakage during movement.
