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.
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]
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 AWS defines welding PQR as a record of welding variables used to produce an acceptable test weldment and the results of tests conducted on the weldment to qualify a Welding Procedure Specification. For steel construction (civil engineering structures) AWS D1.1 is a widely used standard.
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.
In addition to welders and welding machine operators, there are also schemes to independently certify welding inspectors and related specialities. The duties of the welding inspector are described in ISO 14731; [12] however the requirement for inspector certification are not standardized, so there are differences in requirement between the various schemes.
