Abstract: A method and apparatus for preventing a sag of a panel, in which plate to be attached to a skeleton is located on the skeleton supported by a support means, both end parts of the plate are gripped by grasp electrodes of a resistance heating device, current is caused to flow through the plate by the grasp electrodes so as to preheat the plate to a predetermined temperature and to thermally expand it, the plate is welded to the skeleton by a welding machine, and a residual tensile stress is developed in the plate by the thermal shrinkage deformation attendant upon cooling of the plate after the welding. In the case where the plate has a cut-away part, electric conduction members for short-circuiting the cut-away part are interposed in this part so as to form electric conduction paths for the preheating of the plate.

Abstract: A method for preventing discoloration of the area around an indentation in spot welding is provided in which the weld zone and its surrounding area are masked with a non-oxidizing gas such as argon gas, helium gas, nitrogen gas or a mixture of argon gas and carbon dioxide gas from ambient atmospheric air and spot welding is carried out in the atmosphere of the non-oxidizing gas to prevent the discoloration from occurring at the weld zone of a metal sheet under the influence of heat during spot welding.

Abstract: A muffler for a motor vehicle which serves as a reactor for oxidizing or re-burning unburned constituents in engine exhaust gases. The muffler comprises a heat insulated inner shell in which a chamber is provided with a silencing unit and is kept at a high temperature sufficient to oxidize the unburned constituents, an outer shell covering the heat insulated inner shell, and means for absorbing the thermal expansion of the inner shell provided in a supporting device of the inner shell. An exhaust pipe extends into the inner shell and has one end provided with a collector. The collector has a guide opening to pass engine exhaust gases into the inner shell while achieving mixing of the exhaust gases in the collector thereby to promote oxidizing reaction of the exhaust gases.
