Resistance Welding Apparatus TRIZ Cases

A boron-silicon medium-manganese composition forms a tough, weldable hot-rolled steel sheet without complex cooling.

Controlled Mn-Si-B composition and cooling create bainite-rich hot-rolled steel with high toughness, 1450 MPa strength, and spot weldability.

A camera on the electrode holder and a counterweighted display keep the welding seam visible across vehicle models, reducing weld deviation.

A DC battery and pulsed frequency converter replace diesel rail welders, cutting fuel use and emissions while maintaining welding power.

Coordinated electrode speeds cut detection load on the workpiece while limiting welding gun vibration and path deviation in spot welding.

Expansion and contraction gradient features feed a machine learning model to improve resistance spot weld quality assessment under process disturbances.

Molten-part volume change reveals small spatter events in resistance spot welding, improving detection accuracy and weld quality.

A sliding, rotatable guide stop on the lower arm keeps spot welding electrodes aligned on sheet metal and helps avoid seal damage.

Post-weld vibration releases residual hydrogen from the nugget, improving delayed fracture resistance in high-strength steel joints.

Inline electrical signals and machine learning replace destructive weld tests, improving spot weld quality prediction for high-volume production.

Depositing material at the weld interface prevents electrode indentation in metal sheets while preserving weld strength and surface finish.

Sensors trigger coil-end welding and clamping so stamping lines can switch from old to new material without shutdown or uneven feed.

A single ball spline guide and offset rod keep the movable electrode aligned while reducing welding gun width and preserving stable pressure.

Post-weld cancellation stress offsets cooling-induced residual stress in projection-welded nut joints, reducing delayed fracture.

A rotating probe and anvil combine friction stir bonding with resistance welding to join layered dissimilar metals faster with stronger bonds.

Stacked wire mesh circuits enable resistive welding of angled 3D thermoplastic composite joints while preventing current shunting and weld failure.

A detachable dual-heating tool head simplifies assembly and enables 360-degree positioning for more flexible plastic repair welding.

A high-resistivity interlayer concentrates Joule heat during resistance welding of dissimilar steels, improving penetration and joint strength.

A spacer device creates a localized gap between components to concentrate welding current at the resistance point during one-sided joining.

Segmented vibration electrodes induce widespread plastic flow to achieve strong solid-phase welding without surface defects.

A servo-driven cam flash butt welding machine uses a programmable curved body to control holding unit movement.

Evaluating phosphorus concentration gradients in resistance spot weld nuggets prevents interface failure and brittle fracture.

Predicts displacement when allowable load becomes zero by modeling progressive failure across tension, compression, bending, and torsion modes.

A tong-type welding apparatus clamps a beading flange between an electrode and support to join sheet metal parts.

Inclined end surfaces direct melted metal flow inward during resistance welding, preventing radial protrusions that block component insertion.
