Is it possible to carry out these welding operations when the materials are different? Im thinking of an application where i might want to weld HDPE and Glass Filled Nylon 66.
Im trying to design a pipeline fitting that can be welded to a HDPE or PVC pipeline , the fitting will need to be manufactured out of something with high UTS and Hardness
Can anyone share any information on the technical challenges of doing such an operation .
Regards
Carlos

Not generally a good idea to weld dissimilar materials, plastics even more so, and getting such a joint certified for a pipeline...sheesh. But, crazier ideas have been proposed. A lot of research and time would need to be invested to determine methods for joining and suitable NDT to find flaws in the resultant joints, etc. etc.
The function of a circuit breaker is to provide overload (thermal) and short-circuit (magnetic) protection to a circuit and its downstream components. A circuit breaker functions like an airbag in a car, protecting circuit components and people by tripping the circuit to interrupt the current flow if it detects a fault condition in the control system.

As with any new technology, getting into large-format 3D printing begins with investigation. The first question may be a simple one: what does “large-format” mean? For 3D printers, “large” is a relative term. Many extrusion-based (FFF) 3D printers are referred to as desktop machines, because they fit on table space. Some of these have very respectable build volumes – but when it comes to “large-format,” the machines will need their own dedicated floor space. Large-format 3D printers have significant build volumes and are most often found in professional settings, like manufacturing facilities and R&D centers. Download Now
