Traditionally, there are gas welding methods, arc welding methods, electric pressure welding methods, seam welding methods, etc. to join two metal profiteers, but all of them involve heating the joint to a high temperature locally and simultaneously supplying a filler.

For these metals, -8 gold has a particle size of 60 mesh or more, preferably 100 mesh or more, and is coated with shellac and thickened using a bonding material such as thermoplastic resin. Form into a thin, uniform notebook shape with a thickness of 2 mm to several mm. The filler formed in this way is cut to an appropriate size, and if desired, is pasted and sandwiched between the joining surfaces of the two metal bodies to be joined using an adhesive such as epoxy/resin. Make it into a sandwich shape. These are then introduced into a furnace surrounded by a protective gas such as hydrogen gas, helium gas, chiron gas, carbon dioxide gas, or a mixture thereof.

The method of the present invention is useful for manufacturing metal articles consisting of a combination of several metal products having a total weight of several six grams to several tens of kilograms from the viewpoint of workability, furnace thermal efficiency, etc. Therefore, this method is suitable for manufacturing articles that are mass-produced from various metal parts of industrial machinery, such as mounting fittings for hydraulic and pneumatic cylinders. Hydraulic and pneumatic cylinders are used in all industrial fields as a drive source for linear motion, and even for cylinders of the same size, different mounting brackets are required depending on the mounting location.Therefore, mounting brackets of various shapes are required. needs to be mass-produced. For example, a trunnion metal fitting, which is one of them, has a shape that has cylindrical protrusions pointing outward at two opposite positions on the circumferential surface of a metal ring. There are two methods: to create the original shape by casting or forging and then cutting it, or to manufacture the metal ring and the two cylindrical protrusions separately (this is easy to do), or to join them together by arc welding. These methods have drawbacks in terms of workability during manufacturing and the strength of the manufactured trunnion fittings.
It's been a long time since I've been satisfied. When applying the method of the present invention to the manufacture of this trunnion fitting, the metal ring and the two cylindrical protrusions are manufactured by appropriate cutting, and the metal-straddle alloy and Sorted fillers made of a binder with a thickness of 0.0 gm were pasted with adhesive and held in the shape of sandpaper, and heated at a temperature of 1350° C. for 15 minutes in an atmosphere of hydrogen gas. This is done by allowing it to cool down naturally afterwards. The shear stress of the joint of the trunnion fitting manufactured in this manner was measured to reach 88,000 PSi, which is sufficient strength as a mounting fitting for a hydraulic/pneumatic cylinder.

The bond between the alloy metals is strong and great strength can be obtained. Since the filling material is still formed in the form of a sheet, by producing a large quantity of the sheet-like filling material in advance, the work becomes easier and more reliable, and the work efficiency is improved. Furthermore, since the sheet-shaped filler material is pasted between the joint surfaces and heated at a temperature of 110,000 to 1,600°C in an atmosphere of 1 mm gas, metal profiteering can be performed continuously and automation is easy. This is the ability to improve productivity.
