The induction welding coil is configured as or otherwise includes a conductive element. This conductive element is configured into at least a plurality of loops arranged within a common plane.

A welding method, which subjects a surface to be built-up of an elongated workpiece to a build-up welding process along a longitudinal direction of the workpiece, includes a step for forming a build-up layer on the surface to be built-up by supplying a filler metal to the surface to be built-up along the longitudinal direction and by applying a laser beam thereto to melt the filler metal. A refrigerant is supplied to the surface to be built-up of the workpiece, during the step for forming the build-up layer.

A method and apparatus for depositing metals and metal-like substances in two and three dimensional form without a substrate in a safe, rapid and economical fashion using gas shielded arc welding equipment and programmable robotic motion. The method and apparatus includes the use and application of robotic controls, temperature and position feedback, single and multiple material feeds, and semi liquid deposition thereby creating near net shape parts particularly well suited to rapid prototyping and lower volume production. Anchor tabs applied as a first layer of deposited material and platen temperature control are provided to improve adherence and removal from the build surface.

Systems and methods are disclosed relating to welding-type power supplies. In some examples, the power supplies may have no vents, which may help prevent environmental contaminants from entering the power supplies. Instead, the power supplies include one or more thermal interfaces configured to conduct heat generated by internal circuitry of the power supply from the interior of the power supply to an exterior of the power supply. Additionally, the thermal interface(s) may be configured for attachment to one or more exterior heat dissipating devices.

A method of controlling a welding cap cooling water controller having a cooling water pipe which includes a test section with a welding cap between an inlet valve in the cooling water inlet and a return valve in the cooling water return, in a first step the pressure of the cooling water in the test section is increased to an overpressure which is above a supply pressure that prevails in the test section during the welding process with the inlet valve open and the return valve open, and subsequently a pressure drop measurement is performed at overpressure. Furthermore, a welding cap cooling water controller is provided which is adapted to carry out such a method.
