Her father died in 1947 at the age of 49, shortly before his daughter's fourth birthday. Her mother, Yosene Balfour Ker, daughter of the artist and Life illustrator William Balfour Ker, was born in Ealing, Middlesex, England. [2] She was Lathrop Weld's fourth and last wife. [3] [4] Canadian-born William Balfour Ker had Scottish ancestry. [5]
These included three sons and a daughter, Yosene Balfour Ker, who was a model featured in several paintings by the artist John Sloan, [16] [17] and whose own daughter is actress Tuesday Weld (born Susan Ker Weld). [18] [19] Grave of Ker in Rock Creek Cemetery. Ker died on October 20, 1918, [20] in New York City, [1] at the age of 41.
This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]
The weld time in this process is between 1 and 6 milliseconds. Capacitor discharge stud welding with the latest equipment can create a weld without burn-through showing on the opposite side of very thin metals. CD stud welding is often used for smaller diameter studs and pins, as well as on non-standard materials and for accuracy.
Weld mapping is the process of assigning information to a weld repair or joint to enable easy identification of weld processes, production (welders, their qualifications, date welded), quality (visual inspection, NDT, standards and specifications) and traceability (tracking weld joints and welded castings, the origin of weld materials).
The symbolic representation of a V weld of chamfered plates in a technical drawing. The symbols and conventions used in welding documentation are specified in national and international standards such as ISO 2553 Welded, brazed and soldered joints -- Symbolic representation on drawings and ISO 4063 Welding and allied processes -- Nomenclature of processes and reference numbers.
A time–distance diagram is a chart with two axes: one for time, the other for location. The units on either axis depend on the type of project: time can be expressed in minutes (for overnight construction of railroad modification projects such as the installation of switches) or years (for large construction projects); the location can be (kilo)meters, or other distinct units (such as ...
In general, the operator factor, or the percentage of operator's time spent laying weld, is approximately 25%. [13] The actual welding technique utilized depends on the electrode, the composition of the workpiece, and the position of the joint being welded. The choice of electrode and welding position also determine the welding speed.
