Purge gas apparatus and method for a welding system uses automatic purge gas flow control function, such as an MFC, to control ID and/or OD purge gas flow rate or purge gas pressure or both at the weld site.

Welding purge control using electronic flow control

Mechanically attached connections for conduits may include a conduit gripping member and first and second connection members. The first and second connection members may be, for example, a nut member and a body member where the connection members cause axial movement of the conduit gripping member to grip and seal the conduit when the assembly is pulled-up. The mechanically attached connection may include a sensing function for detecting or sensing a condition or characteristic of at least one of the following: the mechanically attached connection, one or more of the connection members, the fluid contained by the mechanically attached connection, or a combination thereof. The sensing function may be, for example, a sensor that is integrated with at least one of the nut member and the body member.

Conduit connection with sensing function

A DC arc start function for a welder. The arc start function is realized using a universal input DC regulator coupled to a DC to DC converter that produces a regulated DC voltage that is sufficient to strike an arc at an electrode of the welder.

Apparatus having DC arc start in parallel with welder power supply

Apparatus and method for determining relative and/or absolute axial position of a conduit end within a fluid coupling includes application of input ultrasonic energy in the form of transient shear waves and analyzing the reflected energy. Application of the input energy collected at different radial positions about a first axial location is used with wavelet based correlation techniques to better analyze the reflected energy signals. Quality of the abutment between the conduit end and a surface associated with the coupling may also be determined as a separate or combined feature of the axial position determination.

Hand-held apparatus and method for determining relative and/or absolute axial position of a conduit end within a fluid coupling includes application of input ultrasonic energy in the form of transient shear waves and analyzing the reflected energy. Application of the input energy collected at different radial positions about a first axial location is used with wavelet based correlation techniques to better analyze the reflected energy signals. Quality of the abutment between the conduit end and a surface associated with the coupling may also be determined as a separate or combined feature of the axial position determination.
