Abstract: An adjustable electric coil for magnetic particle inspection has a plurality of telescopically interconnected sections. Each of the interconnected sections includes a connector element and a conducting element. The conducting element is joined at a proximal end to an end surface of a peripheral wall of the connector element, and a central opening is defined through the connector element on one side of the conducting element. The conducting element of each section is inserted through the central opening of an adjacent connector element of an adjacent section.

Abstract: A method of repairing a cast iron component is disclosed. The method may include removing a damaged or defective portion of the cast iron component, and pre-heating the cast iron component to a temperature in a range from 200-800 degrees F. After pre-heating, the method may include welding a removed area of the cast iron component using a Cold Metal Transfer (CMT) process with a consumable wire electrode made from one of a carbon steel alloy, a nickel alloy, or a nickel-iron alloy material having a Coefficient of Thermal Expansion (CTE) that is within ±10% of a CTE of the cast iron material of the cast iron component to fill the area where the damaged or defective portion was removed. After welding, the cast iron component may be cooled and the welded portion of the cast iron component may be final machined.
