摘要: A method for joining two dissimilar metal plates having different volume resistivity with enhanced joint strength. The method includes overlaying a first metal plate made of first metal and a second metal plate made of second metal with higher volume resistivity and higher melting point in comparison with the first metal, bringing a pair of electrodes into contact with the surface of a portion of the second metal plate overlapping the first metal plate, supplying current between the electrodes so as to resistance-heat the second metal present in a current-flowing region to a temperature lower than the melting point of the second metal and higher than the melting point of the first metal, thereby partially melting the first metal plate with the heat so that an intermetallic compound is generated between the first and second metal plates, and thus joining the first and second metal plates via the intermetallic compound.

摘要: A hybrid weld joint for joining sheet metal pieces together. According to one example, the hybrid weld joint exhibits characteristics of both butt welds and lap joints and is used to create a tailor-welded blank assembly where at least one sheet metal piece is made of aluminum or an aluminum-based alloy. Such a tailor-welded blank assembly is particularly suitable for the automotive industry.

摘要: A method for manufacturing structural steel components with local reinforcement is provided. The method comprises selecting at least a zone of the component to be reinforced, providing a steel blank and deforming the blank in a press tool to form a product, wherein the blank and/or the product comprises a groove in the zone to be reinforced, the groove comprising an inner surface and an outer surface. The method further comprises depositing a reinforcement material on the inner surface of groove and locally heating the reinforcement material and the groove of the steel blank or product, to mix the melted reinforcement material with the melted portion of the steel blank or product.

摘要: Improved free-swinging hammermill hammer configurations are disclosed and described for comminution of materials such as grain and refuse. The hammer configurations of the present disclosure are adaptable to most hammer mill or grinders having free-swinging systems. The configurations as disclosed and claimed are non-forged and incorporate a saddle or hammer mouth. The merging of a hammer and saddle improves strength to reduce or maintain the weight of the hammer while increasing the amount of force delivered to the material to be comminuted. The improved configurations incorporate comminution edges having increased hardness for longer operational run times. The improved configurations improve installing, removing, and cleaning hammer components within the hammermill. The improved configurations may incorporate hammermill rod hole of varying shapes and sizes and saddles of varying shapes and sizes or the use of non-planar hammer bodies that have a recessed or protruding surface.

摘要: A method and system for joining relatively thick (i.e., at least 0.07 inch, or between 0.08 and 0.24 inch) sheets of non-weldable aluminum or other material using multiple passes of ultrasonic joining and multiple plugs to create a single larger sheet. Angles and profiles are machined onto edges of the sheets, the angles are overlapped to form a scarf joint, and ultrasonic joining is performed on both sides of the scarf joint, resulting in channels where the angles and profiles intersect. Plugs are extruded or otherwise created and positioned in the channels, and ultrasonic joining is used to join the plugs in the channels. Additional plugs are added until the last plugs are proud of the surface, and then the plugs are machined until the joint is flush with the surface. The plugs may be of the same or a different material as the sheets.

摘要: Provided is a method for machining micro-holes in a metal or alloy product which relates to the field of micro-hole machining. The method reduces the duration of ejection of primary plasma and the residuals produced during the ejection of the primary plasma, improves the smoothness of the hole wall of the micro-hole, and increases the depth limit of the micro-hole. Injecting energy by low-energy pulse laser in two attempts further facilitates the reduction of the diameter of the micro-hole and reduces the possibility of cracks, compared with injection same energy by single high-energy pulse laser. Moreover, a ratio between the diameter of the central ring of the ring spot formed by the focused second laser beam and the diameter of the central ring of the Gaussian spot formed by the focused first laser beam is greater than 1, which can improve the injection efficiency of laser energy.

摘要: First steel material, a carbon sheet, and second steel material are put in a state of being separated from each other, and bonding parts are heated by, for example, applying current from a power supply to the carbon sheet. Alternatively, the bonding parts may be heated by an inductive heating coil. Thereafter, heating is terminated if the bonding parts reaching greater than or equal to the eutectic point and less than the liquidus line temperature is detected in the Fe—C phase diagram. Furthermore, the carbon sheet is made to be sandwiched between the first steel material and the second steel material.

摘要: A method of assembling a first part made from a metal and a second part includes providing a first part comprising an assembly surface, and a second part comprising at least one through orifice. At least part of the second part is arranged on the assembly surface such that the orifice extends across from the assembly surface. A metal connecting part is positioned on the orifice to cover the orifice across from the assembly surface. The connecting part and/or the assembly surface are projected on one another to obtain high-speed plating and welding between the connecting part and the surface part.

摘要: A method of bonding a first frame member and a second frame member includes: a protrusion formation step of forming a protrusion in a predetermined region of a plate by press fabrication; a stacking step of producing such a stack body of flanges and the plate that a leading end of the protrusion of the plate contacts with the flange and the flange is disposed between the flange and the plate; and a welding step of welding the protrusion to the flange by applying welding current between a pair of electrodes while the stack body is sandwiched between the pair of electrodes so that the protrusion is pressed against the flange.
