Short answer:<\/strong> Resistance spot welded stamped assemblies should be quoted with a weld map, not only a part drawing. The RFQ should define material stack, coating, weld locations, access for electrodes, datum fixture, cosmetic limits, distortion control, peel or shear test requirements, sample quantity, and whether welding happens before or after plating, powder coating, or hardware insertion.<\/p>\n

Spot welding can turn several giporma nga mga piyesa into a ready-to-install bracket, cover, shield, chassis feature, or reinforcement. It can also create distortion, marks, weak nuggets, coating burn, or missed welds if the joint design and inspection plan are vague.<\/p>\n

Spot welded assembly RFQ decisions<\/h2>\n\n\n\n\n\n\n\n\n
Decision<\/th>\nWhy it matters<\/th>\nRFQ detail<\/th>\n<\/tr>\n<\/thead>\n
Weld map<\/td>\nThe tagasuplay needs exact weld count, location, and sequence.<\/td>\nWeld symbols, diameter target, spacing, and priority welds.<\/td>\n<\/tr>\n
Stack and coating<\/td>\nMateryal thickness and coating change heat, marks, and strength.<\/td>\nMateryal stack, plating, galvanized layer, paint, and clean zones.<\/td>\n<\/tr>\n
Access and fixturing<\/td>\nElectrodes must reach the joint without moving datums.<\/td>\nElectrode access, fixture datums, clamp points, and assembly orientation.<\/td>\n<\/tr>\n
Strength evidence<\/td>\nVisual weld marks do not prove joint strength.<\/td>\nPeel, shear, chisel, macro, sample size, and report format.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Start with the weld map and assembly function<\/h2>\n

A stamped assembly drawing should show which surfaces locate the product, which parts carry load, and which welds are structural, grounding-related, cosmetic, or only for handling. If the weld map is missing, the tagasuplay may quote the wrong weld count or choose a sequence that distorts the assembly.<\/p>\n

Spot weld spacing, edge distance, flange width, stack thickness, and access are part of DFM. A weld too close to a bend or pierced hole can mark the part or lose strength. If the assembly also has inserted hardware, review sequence with the inserted hardware torque-out and push-out guide<\/a>.<\/p>\n

For assemblies that must sit flat against a mating frame, define the check condition before approval. A part may pass weld strength and still fail installation because weld shrinkage moves datums, bows a flange, or pulls holes out of position after the final fixture is released.<\/p>\n

Coordinate welding with coatings and flatness<\/h2>\n

Galvanized steel, plated parts, pre-coated sheet, and powder coated components behave differently around welds. Some assemblies should be welded before finishing. Others need masked weld zones or post-weld cleaning. Define acceptable burn marks, spatter, discoloration, and exposed metal before the quote is compared.<\/p>\n

Welding can also move holes, bend angles, and flatness. The RFQ should state whether the assembly is inspected free-state or in a fixture. For vibration-sensitive or load-bearing assemblies, connect the weld plan to the vibration fatigue guide<\/a> and the run-at-rate capacity validation guide<\/a>.<\/p>\n
