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.
