摘要： The art has experienced difficulty obtaining “sound” welds with high-nickel welds above the second pass. Particular problems are tension anomalies and sub-optimal interweld pass fusion at higher order passes of the weld wire, along with undesirably high heat levels transferred to the workpiece. The inventors have discovered that ductile iron-to-ductile iron welds can be reliably formed at mission-critical junctures by compensating for the brittle nature of the heat affected zone through enhancing ductility of the weld itself. The present invention provides in continuing part for a highly durable weld without soundness problems such as tension anomalies, multilayer fusion imperfections, or pinholes; and a method of forming such a weld. The weld is created using high nickel weld wire (filler metal or consumable electrode, or both) welded in a pure inert gas (or mixture of pure inert gasses and even reducing gasses). Additions of weld metal alloys, flux coring, and deoxidizing coatings are not required. The work pieces do not require pre- or post-heat treatment to minimize the effects of the HAZ. Additional inventive features are described more fully below.

摘要翻译： 在第二次通过以上的高镍焊缝获得“声音”焊缝方面遇到困难。 特殊的问题是焊丝高阶通过时的张力异常和次优的焊缝间熔合，以及传递到工件的不希望的高的热量。 本发明人已经发现，通过增强焊接本身的延展性，可以通过补偿热影响区的脆性来可靠地形成球状铁 - 球墨铸铁焊缝。 本发明连续地提供了耐久性很好的焊缝，没有诸如张力异常，多层聚合缺陷或针孔的健全问题; 以及形成这种焊接的方法。 使用焊接在纯惰性气体（或纯惰性气体甚至还原气体的混合物）中的高镍焊丝（填充金属或可消耗电极，或两者）焊接。 不需要添加焊接金属合金，焊剂取芯和脱氧涂层。 工件不需要进行前后热处理，以尽量减少HAZ的影响。 下面将更充分地描述附加的发明特征。

摘要： A gasket for preventing separation of interconnected pipes including a compressible body having a plurality of metal segments partially embedded therein. Each of the metal segments includes an inner surface having at least one tooth configured for engaging a spigot end of a pipe and an outer surface having an arm with a substantially flat portion arranged adjacent to a forward section of a retainer groove of the gasket, the substantially flat portion being configured for displacing the segment radially and axially upon insertion of the spigot end into a bell end of the other pipe thereby decreasing the spigot insertion force required to seat the spigot end within the bell end and the gasket.

摘要： A gasket for preventing separation of interconnected pipes without damaging the pipes. The gasket includes a compressible body having a plurality of metal segments partially embedded therein. Each of the metal segments includes a row of exposed teeth configured for engaging a spigot end of a pipe and a trough configured for pivotably engaging a bead on a bell. The trough is further configured for shearing or deforming the bead and inhibiting over-pivoting of the segment about the bead when the pipes are partially withdrawn away from one another, for example, during over-pressurization of the pipes.

摘要： A gasket for converting a standard mechanical joint into a restrained mechanical joint without the need for altered configuration of the bell, spigot, or gland of the joint, and without the need for additional fittings or devices. In the practice of the present invention, a standard mechanical joint's bell and gland configuration can be employed to connect a spigot end of one pipe length to the bell end of another pipe length in a restrained relationship, with the restraint based on forces superior to rubber-to-pipe friction. In more particular discussion of the embodiments taught, the invention includes forming the gasket to fit within the bell in such a manner that a void, or gutter, exists during rest, into which void the gasket compresses, which in turn influences the rotational motion of the segment. In this manner, the configuration of the gasket influences the timing and extent of rotation throughout the process of securing the gland to the bell.
