Methods of repair of a component or adding material to a component using laser welding are disclosed. One method may include repairing or adding material to the component by laser irradiating a wire material with a laser in an inert gas in a vicinity of the component. The laser irradiating the wire material includes modulated pulsing the laser through: a warm up phase during which an on-power of the laser is increased over time to a maximum target on-power, a melt and bond phase during which the wire material is melted and during which the on-power is less than the maximum target on-power, and a stress releasing phase during which the on-power of the laser is less than the on-power during the melt and bond phase. The laser irradiated wire material forms a weld material to repair a damaged area or add material to the component.

A coke plant includes multiple coke ovens where each coke oven is adapted to produce exhaust gases, a common tunnel fluidly connected to the plurality of coke ovens and configured to receive the exhaust gases from each of the coke ovens, multiple standard heat recovery steam generators fluidly connected to the common tunnel where the ratio of coke ovens to standard heat recovery steam generators is at least 20:1, and a redundant heat recovery steam generator fluidly connected to the common tunnel where any one of the plurality of standard heat recovery steam generators and the redundant heat recovery steam generator is adapted to receive the exhaust gases from the plurality of ovens and extract heat from the exhaust gases and where the standard heat recovery steam generators and the redundant heat recovery steam generator are all connected in parallel with each other.

Embodiments of an alloy that can be resistant to cracking. In some embodiments, the alloy can be advantageous for use as a hardfacing alloys, in both a diluted and undiluted state. Certain microstructural, thermodynamic, and performance criteria can be met by embodiments of the alloys that may make them advantageous for hardfacing.

A repair kit and associated method for repairing an automotive coolant pipe for fluid-conducting within an engine block of an engine includes at least a repair stent with a flared end, sealant and instructions for performing the method. The method includes draining coolant from the engine, removing the water pump from the engine without removing the timing chain cover of the engine, inserting the repair stent including a sealant through the coolant passage, wherein the coolant passage extends through the timing chain cover into the engine, re-assembling the water pump to the engine and adding coolant to the engine.

A method of braze repair for a superalloy material component. Following a brazing operation on the superalloy material, the component is subjected to an isostatic solution treatment, followed by a rapid cool down to ambient temperature under pressure The conditions of the isostatic solution treatment combined with the cool down at pressure function to both reduce porosity in the component and to solution treat the superalloy material, thereby optimizing superalloy properties without reintroducing porosity in the braze.

A component has an edge extending in a first direction. The component includes a filler disposed in the component. The filler has at least a first portion and a second portion. The first portion extends in a second direction from the edge into the component. The second portion of the filler extends from the first portion in a third direction. The second direction is substantially orthogonal to the first direction.

An assembly and method for repairing sheathing on a tension member of a post-tensioning tendon may include an outer tube having first and second end portions, a tubular long seal positioned inside the outer tube, the tubular long seal being shorter than the outer tube, first and second seals positioned in the first and second end portions of the outer tube, respectively, and first and second nuts retaining the first and second seals in the first and second end portions of the outer tube, respectively. The assembly may define a longitudinal passage adapted to receive the tension member and the presence of the assembly on the tension member seals the portion of the tension member that is within the assembly. An inner tube may be positioned between the outer tube and the tubular long seal and may radially compress the tubular long seal.
