A suspension arm includes a ball stud including a spherical ball; a bearing in which the spherical ball is accommodated; a housing having an inner peripheral portion and an outer peripheral portion; an arm body coupled to the outer peripheral portion of the housing; and an insert molding part which is injected to a lower portion of the bearing and the outer peripheral portion of the housing to be coupled to the bearing, the housing, and the arm body. The housing includes a matching portion having a matching surface formed to protrude in a radially outward direction from an upper portion of the outer peripheral portion and to be brought into contact with a mold. By forming the matching portion, it is possible to reduce the volume of the housing and to reduce the weight of the suspension arm while providing the matching surface with the mold.

Devices and methods to extract a desired product from organic matter using supercritical fluid extraction processes are described herein. The extraction vessel generally includes a reaction chamber, a water jacket affixed to the reaction chamber capable of separate pressurization, and a closure mechanism with a gasket, a plug, and a cap ring with ACME threading. The extraction vessel may be sealed by hand closure without a need for additional tools to create a seal able to withstand pressures up to 5,000 psi.

A hybrid bumper assembly for a vehicle includes a steel reinforcement beam and aluminum crush cans attached to end portions of the steel reinforcement beam. The reinforcement beam has a multi-tubular shape that is formed by a high-strength steel sheet that is roll formed to provide at least two tubular portions. A crush can has an interfacing portion that is coupled to an end portion of the reinforcement beam. The end portions of the reinforcement beam and the interfacing portion of the crush cans may be configured to attach together using a select joining technology in a manner that minimizes or eliminates bimetallic or galvanic corrosion between the reinforcement beam and the crush cans.

A technique for creating a weld along a joint. A method begins by positioning a first edge of a first member proximate to a second edge of a second member to form the joint, wherein the joint is to be welded along the length from a first position on the joint to a second position on the joint. A clamping ring of a refill spot welding apparatus is placed to surround an unwelded portion of the length. The clamping ring contacts a top surface of the first member and a top surface of the second member. A first refill spot weld process is performed with the refill spot welding apparatus to join the first member and the second member at a first spot weld on the joint.

A honeycomb panel 1 includes: a honeycomb core 10 having a front surface 10A and a rear surface 10B; and a first plate member 11 provided on the front surface 10A of the honeycomb core 10; a first flange part 111 projecting inside a cell 10S is provided on an end edge of trapezoidal portions 101, 102 of one or more core strips 100 forming the honeycomb core 10, the end edge being positioned on the side of the first plate member 11. The first plate member 11 has one or more through-holes 121 overlapped with the first flange part 111, and is joined to the honeycomb core 10 by welding an outer surface of the first flange part 111, which faces outside through the through-hole 121, and an inner circumferential surface of the through-hole 121.

The present invention relates to an arc welding method for dissimilar material joining for joining a first plate made of an aluminum alloy or a magnesium alloy and a second plate made of steel. A steel-made joining assist member has a stepped external shape including a large-diameter portion and a small-diameter portion, has a hollow portion formed to penetrate the large-diameter portion and the small-diameter portion, and has a total height of the large-diameter portion and the small-diameter portion being equal to or larger than a thickness of the first plate. A pressure is applied to the joining assist member to punch the first plate. The hollow portion of the joining assist member is filled with a weld metal. The weld metal is melted until a penetration bead is formed on the second plate, to weld the second plate and the joining assist member together.

An example system includes: a hand-held welding tool that is manually placed in a welding position, wherein the hand-held welding tool is configured to be activated to cause a contact tip or a welding heat source to automatically move from a first position and to second position during a welding operation, and wherein a welding arc is automatically and repeatedly turned off and on while the contact tip or the welding heat source moves from the first position to the second position to make a plurality of welds between the first position and the second position, wherein, as a travel speed decreases, a time period between each arc on time increases to make equally spaced welds.
