Identifying the right cutting and welding tips The tip of a welding or cutting torch is where the action is (see Figure 1 ). Welding tips usually produce positive pressure (higher than 1 pound per square inch ) and are used at equal pressures of acetylene and oxygen. These single-hole copper-alloy tips are attached to a torch handle... Read more...

Minimizing wall thickness variation in seamless tubing Reducing the amount of variation, or achieving more wall thickness consistency, can be the difference between meeting a customer's requirements or not. It also helps to reduce or even may eliminate the customer's need for subsequent processes such as machining. Seamless tube typically is... Read more...

What's that material? An XRF system can be integrated at a detector station before final packaging. The tubes are held in place by a pneumatic clamp while the XRF detector is raised to make contact with the tube and perform the measurement. This process confirms the alloy grade of the material typically in two... Read more...

Effective simulation of hydroforming: Current capabilities and requirements for the future Simulation is used in the hydroforming process to replace the experimental investigation and tests required in a real tryout process. Simulation of hydroforming becomes especially relevant if the feasibility of the metal forming processes has to be checked before expensive tools are actually... Read more...
