The weld access hole or rat hole is a structural engineering technique in which a part of the web of an I-beam or T-beam is cut out at the end or ends of the beam. The hole in the web allows a welder to weld the flange to another part of the structure with a continuous weld the full width on both top and bottom sides of the flange.
The weld time in this process is between 1 and 6 milliseconds. Capacitor discharge stud welding with the latest equipment can create a weld without burn-through showing on the opposite side of very thin metals. CD stud welding is often used for smaller diameter studs and pins, as well as on non-standard materials and for accuracy.
TIME-SERT insert. A threaded insert, also known as a threaded bushing, is a fastener element that is inserted into an object to add a threaded hole. [1] They may be used to repair a stripped threaded hole, provide a durable threaded hole in a soft material, place a thread on a material too thin to accept it, mold or cast threads into a work piece thereby eliminating a machining operation, or ...
In the field of aviation, rivet nuts are often used to attach various items, such as static dischargers and inspection access covers, to the surface of an aircraft. [citation needed] Rivet nuts are an ideal replacement for weld nuts because they will not distort base materials, eliminate weld splatter, toxic fumes, and other by-products of the welding process, and can be installed in many ...
Another option is a tripartite weld where the lug on the anode cable is made of steel with a tapered hole in it. The tapered end of the stud welds through the hole onto the pipeline, welding to both the lug and the pipe and providing a fully welded connection between the anode cable and pipeline.
President-elect Donald Trump’s policy agenda is generally good for business, top executives and analysts told me at the Goldman Sachs Industrial and Materials conference this week. “It’s ...
President-elect Donald Trump lost a bid Monday to get his 34 felony convictions tossed out based on a Supreme Court ruling on presidential immunity, but he still has multiple avenues to fight the ...
A robust robotic arc welding fixture is a part-holding tool used to constrain components for welding in an automated system. [15] Welding fixtures locate parts using these clamps to secure important aspects of the subcomponent, such as holes, slots, or datum surfaces. Careful considerations must be made when designing welding fixtures.
